Many of the mammalian faunal assemblages of the Early Pleistocene start in the Gelasian. The effects of this on benthic whale fall community assemblages is not well understood. These are formed by deformation of pre-existing sedimentary rocks which changed its mineral assemblages (metamorphism). Alkali basalts typically have mineral assemblages that lack orthopyroxene but contain olivine. The depositional environment of the majority of Burgess-Shale-type assemblages is outer shelf, deeper water. In contrast, fish assemblages in reefs that experience bleaching exhibit potentially damaging changes. This is consistent with climate interpretations based on contemporaneous paleo-floral assemblages and geological evidence. Among all the late Quaternary assemblages of megafauna, only Madagascar was dominated by large primates. Nonetheless, there are a variety of important species and assemblages. This is supported by fossil assemblages and cave paintings showing groups. Usually, this represents the protolith chemistry, which forms distinct mineral assemblages. Using this scheme, galaxies, star clusters and other large assemblages of objects have been simulated. She is most recognizable for her sloppy craft assemblages of furniture and ceramics. Bat guano also contains pollen, which can be used to identify prior plant assemblages. In January 1996, forensic anthropologists located and exhumed 53 skeletal assemblages.
