Caprinidae

	Caprinidae Caprinidae is a family of rudists, a group of unusual extinct saltwater clams, marine heterodont bivalves in the order Hippuritida. These stationary intermediate-level epifaunal suspension feeders lived in the Cretaceous period, from 140.2 to 66.043 Ma. The rudists became extinct at the end of the Cretaceous, apparently as a result of the Cretaceous–Paleogene extinction event The Cretaceous–Paleogene (K–Pg) extinction event (also known as the Cretaceous–Tertiary extinction) was a sudden mass extinction of three-quarters of the plant and animal species on Earth, approximately 66 million years ago. With the .... Fossils of this genus have been found in the sediments of Europe, China, Cuba, Egypt, Guatemala, Jamaica, Japan, Mexico, Oman, the Philippines, Turkey, Russia, the United States and Venezuela.

picture info	Rudists Rudists are a group of extinct box-, tube- or ring-shaped marine heterodont bivalves belonging to the order Hippuritida that arose during the Late Jurassic and became so diverse during the Cretaceous that they were major reef-building organisms in the Tethys Ocean, until their complete extinction at the close of the Cretaceous. Shell description The Late Jurassic forms were elongate, with both valves being similarly shaped, often pipe or stake-shaped, while the reef-building forms of the Cretaceous had one valve that became a flat lid, with the other valve becoming an inverted spike-like cone. The size of these conical forms ranged widely from just a few centimeters to well over a meter in length. Their "classic" morphology consisted of a lower, roughly conical valve that was attached to the seafloor or to neighboring rudists, and a smaller upper valve that served as a kind of lid for the organism. The small upper valve could take a variety of interesting forms, including: a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Titanosarcolites ''Titanosarcolites'' is a genus of giant rudist bivalve from the Cretaceous. Its fossils have been found in Jamaica, Southeastern Mexico and the Southern US. It belonged to the now extinct family known as Caprinidae Caprinidae is a family of rudists, a group of unusual extinct saltwater clams, marine heterodont bivalves in the order Hippuritida. These stationary intermediate-level epifaunal suspension feeders lived in the Cretaceous period, from 140.2 to ..., a group that went extinct during the KT extinction event, 66 MYA. ''Titanosarcolites'' was one of the last members of this group. There were several species, including ''T. alatus'', ''T. giganteus'', ''T. macgillavryi'' and ''T. oddsensis''. Description ''Titanosarcolites'' was rather large, perhaps being 2 meters in overall size at its largest. References Cretaceous bivalves Hippuritida {{Paleo-bivalve-stub ...

	Heterodonta Heteroconchia is a taxonomic infraclass of saltwater clams, marine bivalve molluscs, belonging to the subclass Autobranchia This infraclass includes the edible clams, the cockles and the Venus clams. Description These bivalves are distinguished by having the two halves of the shell equally sized (i.e, they are ''equivalved'') and having a few cardinal teeth separated from a number of long lateral teeth. Their shells lack a nacreous layer, and the gills are lamellibranch in form. Most species have a siphon.
