Query: When was evidence of the Catopsbaatar first found?
Catopsbaatar is a genus of multituberculate, an extinct order of rodent-like mammals. It lived in what is now Mongolia during the late Campanian age of the Late Cretaceous Period, about 72 million years ago. The first fossils were collected in the early 1970s, and the animal was named as a new species of the genus "Djadochtatherium " in 1974, "D. catopsaloides". The specific name refers to the animal's similarity to the genus "Catopsalis". The species was moved to the genus "Catopsalis" in 1979, and received its own genus ("Catopsbaatar", Greek and Mongolian for "visible hero") in 1994. Five skulls, one molar, and one skeleton with a skull are known; the latter is the genus' most complete specimen. "Catopsbaatar" was a member of the family Djadochtatheriidae.
The Celtiberian inscriptions have been found mainly in the Ebro valley and near the sources of the Tagus and Douro rivers, where Roman and Greek sources place the Celtiberian people. The Celtiberian inscriptions were made on different types of objects (silver and bronze coins, ceramic receptacles, bronze plaques and tesseras, amphores, stones, spindle-whorls, etc.). There are just under two hundred surviving inscriptions, one of which is exceptionally long: the third Botorrita bronze plaque (Zaragoza) with more than three thousand signs containing a census of nearly 250 people. Almost always the direction of the writing is left to right. The fact that nearly all the Celtiberian inscriptions were found out of archaeological context does not allow a precise chronology to be established, but it seems that the earliest inscriptions in the Celtiberian script date from the 2nd century BCE while the latest ones date from the 1st century BCE.
Fossils from other parts of the UK and Iberia, mostly isolated teeth, have subsequently been attributed to "Baryonyx" or similar animals. Isolated teeth and bones from the Isle of Wight, including hand bones reported in 1998 and a vertebra reported by the British palaeontologists Steve Hutt and Penny Newbery in 2004, have been attributed to this genus. In 2017, the British palaeontologist Martin C. Munt and colleagues reported cranial remains of two "Baryonyx" individuals from the Isle of Wight, and stated they would be examined and described in the future. A maxilla fragment from La Rioja, Spain, was attributed to "Baryonyx" by the Spanish palaeontologists Luis I. Viera and José Angel Torres in 1995 (although the American palaeontologist Thomas R. Holtz and colleagues raised the possibility that it could have belonged to "Suchomimus" in 2004). In 1999, a postorbital bone, a squamosal bone, a tooth, vertebral remains, metacarpals, and a phalanx from the Sala de los Infantes deposit in Burgos Province, Spain, were attributed to an immature "Baryonyx" (though some of these elements are unknown in the holotype) by the Spanish palaeontologist Carolina Fuentes Vidarte and colleagues. Dinosaur tracks near Burgos have also been suggested to belong to "Baryonyx" or a similar theropod. In 2011, a specimen (ML1190) from the Papo Seco Formation in Boca do Chapim, Portugal, with a fragmentary dentary, teeth, vertebrae, ribs, hip bones, a scapula, and a phalanx bone, was attributed to "Baryonyx" by the Portuguese palaeontologist Octávio Mateus and colleagues, the most complete Iberian remains of the animal. The skeletal elements of this specimen are also represented in the more complete holotype (which was of similar size), except for the mid-neck vertebrae. In 2018, the British palaeontologist Thomas M. S. Arden and colleagues found that the Portuguese skeleton did not belong to "Baryonyx", since the front of its dentary bone was not strongly upturned. Some additional spinosaurid remains from Iberia appear to belong to taxa other than "Baryonyx".
Cats in ancient Egypt were valued very highly and were seen to be very close to the gods. They believed the cats were an embodiment of the goddess Bastet. Harming a cat in ancient Egypt was an offense punishable by death. When a cat died the Egyptians would mummify and bury their cats as an offering to the gods.
Tsintaosaurini is a tribe of basal lambeosaurine hadrosaurs native to Eurasia. It currently contains only "Tsintaosaurus" (from Shandong, east China) and "Pararhabdodon" (from Spain and France).
"Koutalisaurus", also known from late Cretaceous Spain and formerly referred to "Pararhabdodon" 
, may also be a tsintaosaurin because of its association with the latter genus; some recent work also suggests it may indeed be referrable to "Pararhabdodon".
The fossilized remains of "Homo sapiens idaltu" were discovered at Herto Bouri near the Middle Awash site of Ethiopia's Afar Triangle in 1997 by Tim White, but were first unveiled in 2003. Herto Bouri is a region of Ethiopia under volcanic layers. According to radioisotope dating, the layers are between 154,000 and 160,000 years old. Three well preserved crania are accounted for, the best preserved being from an adult male (BOU-VP-16/1) having a brain capacity of . The other crania include another partial adult male and a six-year-old child.
Platecarpus ("flat wrist") is an extinct genus of aquatic lizards belonging to the mosasaur family, living around 84–81 million years ago during the middle Santonian to early Campanian, of the Late Cretaceous period. Fossils have been found in the United States and a possible specimen in Belgium and Africa. A well-preserved specimen of "Platecarpus" shows that it fed on moderate-sized fish, and it has been hypothesized to have fed on squid, and ammonites as well. Like other mosasaurs, it was initially thought to have swum in an eel-like fashion, although another study suggests that it swam more like modern sharks. An exceptionally well-preserved specimen of "P. tympaniticus" known as LACM 128319 shows skin impressions, pigments around the nostrils, bronchial tubes, and the presence of a high-profile tail fluke, showing that it and other mosasaurs did not necessarily have an eel-like swimming method, but were more powerful, fast swimmers. It is held in the Natural History Museum of Los Angeles County.
Pottery samples recovered from sites in modern Southwestern United States and Northwestern Mexico have tested positive for the ratio of methylxanthines associated with those produced by "Ilex vomitoria". The same study also identified methylxanthines ratios associated with "Theobroma cacao". Neither plants are native to the areas from which the pottery samples were recovered, which suggests trading between areas where those plants are native. The chemical analysis also suggests a possible increase in drinks prepared from cacao after the year 1200, and a decrease in the use of drinks prepared from "Ilex vomitoria". Freshwater shells from Texas and Arkansas have been recovered from Pueblo Bonito, which have been used as possible evidence for the trade of "Ilex vomitoria" from the east. There are also some stands of "Ilex vomitoria" in Mesoamerica, so the exact origins of the "Ilex vomitoria" used to prepare the drinks is currently unknown.
Prieto-Márquez returned again to the dentary in 2013, in a study alongside colleagues providing a review and investigation of hadrosaurs from all over Europe. Further preparation of the specimen in the time since his last study regarding it revealed the uniqueness of the dentary had been exaggerated significantly by reconstruction of the specimen when it was first prepared in the 1990s. The "Tsintaosaurus" specimens showing the similar condition were found to have been distorted from a similar process. Correcting for the innaccuracies, the Los Llaus dentary is indistinguishable from that of multiple lambeosaurines, and shares no particular connection to "Tsintaosaurus". With this, their reasoning for assignment of the specimen to "Pararhabdodon" was voided, and the specimen is now considered a completely indeterminate lambeosaurine dentary.
In 1983, a relatively complete skeleton was excavated from the Smokejacks pit in Surrey, Engand. These remains were described by British paleontologists Alan J. Charig and Angela C. Milner in 1986 as the holotype of a new species, "Baryonyx walkeri." After the discovery of "Baryonyx," many new genera have since been described, the majority on very incomplete remains. However, other finds bear enough fossil material and distinct anatomical features to be assigned with confidence. Paul Sereno and colleagues described "Suchomimus" in 1998"," a baryonychine from Niger on the basis of a partial skeleton found in 1997. Later in 2004, partial jaw bones were recovered from the Alcântara Formation, these were referred to a new genus of spinosaurine named "Oxalaia" in 2011 by Alexander Kellner.
Cats in ancient Egypt were represented in social and religious practices of Ancient Egypt for more than 30 centuries. Several Ancient Egyptian deities were depicted and sculptured with cat-like heads such as Mafdet, Bastet and Sekhmet, representing justice, fertility and power.
The deity Mut was also depicted as a cat and in the company of a cat.
Funerary cults are especially associated with ancient Egypt, where it was common for royalty, those associated with royalty, cats, and the wealthy to be mummified. This practice was done so as to preserve their bodies for the journey to the afterlife. The deity Osiris, who was the dying and reviving god and Lord of the Egyptian afterlife, was usually depicted as a mummy in Egyptian art. Also at Bubastis, where Bast was worshiped, there was a massive cat cemetery. Cats were also thought to journey to the afterlife, usually to join their owners. These needed their own material goods for this journey, such as food.
Since the late 1940s, a strand of scholarship has argued that the African forest elephants used by Numidia, the Ptolemies and the military of Carthage did not carry howdahs or turrets in combat, perhaps owing to the physical weakness of the species. Some allusions to turrets in ancient literature are certainly anachronistic or poetic invention, but other references are less easily discounted. There is explicit contemporary testimony that the army of Juba I of Numidia included turreted elephants in 46 BC. This is confirmed by the image of a turreted African elephant used on the coinage of Juba II. This also appears to be the case with Ptolemaic armies: Polybius reports that at the battle of Raphia in 217 BC the elephants of Ptolemy IV carried turrets; these elephants were significantly smaller than the Asian elephants fielded by the Seleucids and so presumably African forest elephants. There is also evidence that Carthaginian war elephants were furnished with turrets and howdahs in certain military contexts.
Watson Brake is an archaeological site in present-day Ouachita Parish, Louisiana, from the Archaic period. Dated to about 5400 years ago (approx. 3500 BCE), Watson Brake is considered the oldest earthwork mound complex in North America. It is older than the Egyptian pyramids or England’s Stonehenge. Its discovery and dating in a paper published in 1997 changed the ideas of American archaeologists about ancient cultures in the Southeast and their ability to manage large, complex projects over centuries. The archeologists revised their date of the oldest earthwork construction by nearly 2000 years, as well as having to recognize that it was developed over centuries by a hunter-gatherer society, rather than by what was known to be more common of other, later mound sites: a more sedentary society dependent on maize cultivation and with a hierarchical, centralized polity.
The caves and rock shelters vary in size and what they contain. Many contain paintings and other forms of graphic representation. Contents include ceramics and stone tools. The corn materials show similarities to the first vestiges of the domestication of wheat and rye in the Middle East. One of the deepest caves is called the Cueva de la Paloma. The caves have been studied since the 1960s, especially the Cueva de Guilá Naquitz (white stone in Zapotec), which has some of the best evidence for the domestication of corn and squash, which dates back more than 10,000 years. Other caves, such as those near Yagual and Mitla confirm findings at Guilá Naquitz and show human occupation to about 8000 years BCE the sites also show similarities to the Head Smashed and Buffalo Jump Complex sites in Canada. Many more smaller caves with similar artifacts are thought to exist in the area.
Baryonyx () is a genus of theropod dinosaur which lived in the Barremian stage of the Early Cretaceous Period, about 130–125 million years ago. The first skeleton was discovered in 1983 in the Weald Clay Formation of Surrey, England, and became the holotype specimen of B. walkeri, named by palaeontologists Alan J. Charig and Angela C. Milner in 1986. The generic name, "Baryonyx", means "heavy claw" and alludes to the animal's very large claw on the first finger; the specific name, "walkeri", refers to its discoverer, amateur fossil collector William J. Walker. The holotype specimen is one of the most complete theropod skeletons from the UK (and remains the most complete spinosaurid), and its discovery attracted media attention. Specimens later discovered in other parts of the United Kingdom and Iberia have also been assigned to the genus.
The earliest known Ugarit contact with Egypt (and the first exact dating of Ugaritic civilization) comes from a carnelian bead identified with the Middle Kingdom pharaoh Senusret I, 1971–1926 BC. A stela and a statuette from the Egyptian pharaohs Senusret III and Amenemhet III have also been found. However, it is unclear at what time these monuments got to Ugarit. In the Amarna letters, messages from Ugarit BC written by Ammittamru I, Niqmaddu II, and his queen, were discovered. From the 16th to the 13th century BC, Ugarit remained in constant touch with Egypt and Cyprus (named Alashiya).
The earliest true polecat was "Mustela stromeri", which appeared during the late Villafranchian. It was considerably smaller than the present form, thus indicating polecats evolved at a relatively late period. The steppe polecat's closest relatives are the European polecat and black-footed ferret, with which it is thought to have shared "Mustela stromeri" as a common ancestor. The steppe polecat likely diverged from the European polecat 1.5 million years ago based on IRBP, though cytochrome b transversions indicate a younger date of 430,000 years. As a species, the steppe polecat represents a more specialised form than the European polecat in the direction of carnivory, being more adapted to preying on larger rodent species; its skull has a stronger dentition, its projections are more strongly developed and its muscles of mastication are more powerful. The steppe polecat's growth rate is also much slower than the European polecat's, as its skull undergoes further development at an age when the European polecat attains full growth. The species may have once been present in Pleistocene central Alaska.
Puncture marks made by teeth on several "Eutrephoceras" fossils (such as "E. campbelli", of the Trent River Formation in Vancouver) are cited as evidence of mososaur predation on this genus.
The earliest known artifact with Zapotec writing is a "Danzante" ("dancer") stone, officially known as Monument 3, found in San Jose Mogote, Oaxaca. It has a relief of what appears to be a dead and bloodied captive with two glyphic signs between his legs, possibly his name. First dated to 500–600 BC, this was initially considered the earliest writing in Mesoamerica. However, doubts have been expressed as to this dating as the monument may have been reused. The Zapotec script appears to have gone out of use in the late Classic period.
The Talara Tar Seeps in Peru represent a similar scenario, and have also produced fossils of "Smilodon". Unlike in La Brea, many of the bones were broken or show signs of weathering. This may have been because the layers were shallower, so the thrashing of trapped animals damaged the bones of previously trapped animals. Many of the carnivores at Talara were juveniles, possibly indicating that inexperienced and less fit animals had a greater chance of being trapped. Though Lund thought accumulations of "Smilodon" and herbivore fossils in the Lagoa Santa Caves were due to the cats using the caves as dens, these are probably the result of animals dying on the surface, and water currents subsequently dragging their bones to the floor of the cave, but some individuals may also have died after becoming lost in the caves.
"Catopsbaatar" belonged to the order Multituberculata, a group within Allotheria (an infraclass of mammals outside Theria, the group that contains modern placentals and marsupials). Multituberculates are characterized by having premolars and molars with multiple low cusps, arranged in longitudal rows. Multituberculates are the best-known group of mammals from the Mesozoic Era, when the dinosaurs dominated; although the earliest multituberculate remains are from the Jurassic Period, the group is known as recently as the Eocene Epoch (thereby surviving the Cretaceous–Palaeogene extinction event). The group may have become extinct due to competition with eutherian mammals, such as rodents. Multituberculates were mainly known from teeth and jaws until the 1920s, when more complete specimens were discovered—first in Asia, and then elsewhere. Postcranial bones (the rest of the skeleton, other than the skull) remain rare.
At one time, the genus was also formally reported from the upper Cretaceous of Mongolia. However, that material was subsequently referred to the genera of "Djadochtatherium" and "Catopsbaatar". "Catopsalis" is within the suborder of Cimolodonta and a member of the superfamily Taeniolabidoidea.
Although multituberculates were thought to have been carnivores or herbivores, since American palaeontologist William A. Clemens and Kielan-Jaworowska suggested modern rat kangaroos as analogues for the group in 1979 they have been considered omnivores (feeding on both plants and animals). Uniquely among mammals, multituberculates employed a backward chewing stroke which resulted in the masticatory muscles—the muscles which move the mandible—being inserted more to the front than in other groups (including rodents). Gambaryan and Kielan-Jaworowska reconstructed the masticatory musculature of various multituberculates in 1995, and found that "Catopsbaatar" and its relatives had very powerful masticatory musculature, due to their high zygomatic arches and large anterior and intermediate zygomatic ridges and coronoid processes. Their powerful incisors, with limited bands of enamel, would have been well adapted to gnawing and to cutting hard seeds (similar to rodents). Since it was larger than some other multituberculates, "Catopsbaatar" would only have to open its mouth 25 degrees to crush hard seeds in diameter; a 40-degree gape would have caused dislocation. After the incisors cut, the premolars and molars would begin to grind with a "power stroke".
According to Gambaryan and Kielan-Jaworowska, the adaptation for crushing hard seeds sometimes—as in "Catopsbaatar"—opposed the benefit of a low condylar process (which discourages mandibular dislocation). The anterior and intermediate zygomatic ridges of the skull were the origin of the superficial masseter muscle, which facilitates chewing. The separation of the origin of this muscle into two parts and the rounded muscle scars left by them are unique among mammals to multituberculates. The masticatory muscles of multituberculates independently evolved features shared with rodents and small herbivorous marsupials. As with rodents, multituberculates may have been capable of bilateral mastication—where both rows of teeth in the mandible perform the same function simultaneously—and unilateral mastication (where the rows on one side are used).
Kielan-Jaworowska and American palaeontologist Robert E. Sloan considered the genus "Djadochtatherium" a junior synonym of "Catopsalis", and created the new combination "C. catopsaloides" in 1979. American palaeontologists Nancy B. Simmons and Miao Desui conducted a 1986 cladistic analysis which indicated that "Catopsalis" was a paraphyletic taxon (an unnatural grouping of species), and "C. catopsaloides" required its own generic name. Kielan-Jaworowska followed Simmons and Miao's suggestion, moving "C. catopsaloides" to its own monotypic genus ("Catopsbaatar") in 1994. "Catops" is derived from the Greek word "katoptos" ("visible" or "evident"); "baatar" is Mongolian for "hero", and the name refers to "Catopsbaatar"'s similarity to the genus "Catopsalis" (as is the case for the specific name). The name "Catopsalis" itself consists of the Greek words for "visible" and "cutting shears" ("psalis").
Later in 1994, Kielan-Jaworowska and the Russian palaeontologist Petr P. Gambaryan mentioned caudal (tail) vertebrae which may have belonged to "Catopsbaatar"; this attribution is uncertain, since they may instead belong to the related "Tombaatar" (named in 1997). A fourth skull (PIN 4537/4, a juvenile), discovered during the 1975 Soviet−Mongolian Expedition, was mentioned by Gambaryan and Kielan-Jaworowska in 1995. Canadian palaontologist Phillip J. Currie found a new "Catopsbaatar" specimen during the 1999 Dinosaurs of the Gobi expedition, organised by the American Nomadic Expeditions Company. Housed at the Mongolian Academy of Sciences in Ulaanbaatar as PM120/107, this most completely preserved known specimen consists of the complete skull (which may be slightly flattened) and partial skeleton of an adult individual. The specimen has rather complete fore- and hind limbs, which were unknown for the genus until then and which are generally rarely preserved in multituberculates. Its pelvic ilia were stolen and destroyed by a schoolboy on tour at the Natural History Museum of Oslo, when it was prepared in 2000. The specimen was reported in 2002 by Kielan-Jaworowska, Norwegian palaeontologist Jørn Hurum, Currie and Mongolian palaeontologist Rinchen Barsbold, who also mentioned another skull (PIN 4537/5, a juvenile) found during the 1975 expedition. "Catopsalis joyneri", the basis of the name "C. catopsaloides", was moved to the new genus "Valenopsalis" in 2015.
