Tuarangia is a Cambrian shelly fossil interpreted as an early bivalve, [1] though alternative classifications have been proposed and its systematic position remains controversial. [2] It is the only genus in the extinct family Tuarangiidae [ 3 ] and order Tuarangiida . [ 1 ]
The largest known extinct bivalve is a species of Platyceramus whose fossils measure up to 3,000 mm (118 in) in length. [ 64 ] In his 2010 treatise, Compendium of Bivalves , Markus Huber gives the total number of living bivalve species as about 9,200 combined in 106 families. [ 65 ]
The family Camyidae was first proposed by Hinz-Schallreuter in a 2000 paper discussing the Cambrian bivalves from Bornholm and reviewing the proposed Cambrian bivalve taxa of the time. In the same paper, Hinz-Schallreuter noted that the species Modiolopsis thecoides , known from one specimen which is now lost, most likely belonged to Camya . [ 3 ]
Anadara is a genus of saltwater bivalves, ark clams, in the family Arcidae. It is also called Scapharca. [1] This genus is known in the fossil record from the Cretaceous period to the Quaternary period (age range: 140.2 to 0.0 million years ago). These fossils have been found all over the world. [2]
Isognomon is a genus of marine bivalve mollusks which is related to the pearl oysters. [1] Isognomon is known in the fossil record from the Permian period to the Quaternary period (age range: 254.0 to 0.012 million years ago). Fossils of species within this genus have been found all over the world. [2]
