Lithology and environment
Primary lithology: not reported
Environment:marine indet.
Geology comments: the marine Aitym Formation
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils,mesofossils
Collection methods and comments
Collection excludes:some macrofossils
Collection methods:field collection
Reason for describing collection:taxonomic analysis
Collectors:Joint Uzbekian-Russian-British-American-Canadian (URBAC-98) Collection dates:1998
Collection method comments: Collection of the Zoological Institute, Russian Academy of Sciences, Saint Petersburg (abbreviated ZIN)
Taxonomic list comments:The Aitym fauna consists of varied, mainly marine vertebrates (e.g., diverse and abundant chondrichthyans and more rare osteichthyans, infrequent plesiosaurs, sea(?) turtles), and of some marine invertebrates, including oysters, belemnites, and ammonites (Placenticeras kyzylkumense). The remains of terrestrial vertebrates are extremely rare in this site. There are few bones of salamanders and lizards, teeth of crocodiles, shell fragments of possibly terrestrial turtles
