The remains of the dinosaur "Hadrosaurus" have been recovered from this formation. The "Hadrosaurus" remains all persist to the Woodbury Formation. The hadrosaurus had up to 1,400 teeth. Paleontologists have discovered tracks or fossils from ankylosauria, ornithopods (including a Hadrosaurus), and theropods. In Hadrosauridae, he included "Hadrosaurus", "Cionodon", and tentatively "Agathaumas". The creature was named "Hadrosaurus foulkii". Local dinosaurs include ankylosaurs, "Coelosaurus", "Dryptosaurus", and "Hadrosaurus". He also managed to build one last dinosaur, a hadrosaur ("Hadrosaurus foulkii"). Later that same year, he described these bones under the name "Hadrosaurus occidentalis". Leidy called the creature "Hadrosaurus foulkii" after Foulke. Like all hadrosaurids, Hadrosaurus was herbivorous. The dinosaur was later named "Hadrosaurus foulkii" by Joseph Leidy. In the mid-19th century "Hadrosaurus foulkii" was discovered and named. The hadrosaurus lost about 1,800 teeth a year, leaving behind many fossils for testing. Estimates have the "Hadrosaurus" exhibit as increasing the number of visitors by up to 50%.
