The shells of bivalves are used in craftwork, and the manufacture of jewellery and buttons. Bivalves have also been used in the biocontrol of pollution. Bivalves appear in the fossil record first in the early Cambrian more than 500 million years ago. The total number of known living species is about 9,200. These species are placed within 1,260 ...
Bakevelliidae is an extinct family of prehistoric bivalves that lived from the Late Mississippian until the Middle Eocene. [1] Bakevelliidae species are found worldwide, excluding Antarctica. Living a stationary life attached to substrate in marine and brackish environments, they formed shells of an aragonite composition with a low amount of ...

All species of this genus, including the remaining extant species, G. humanus, are found in the fossil record from the Cretaceous to the Pliocene (age range: from 99.7 to 2.588 million years ago). Fossils are found in the marine strata of Eastern North America, Eurasia and the Indo-Pacific. [2] Fossil shell of Glossus humanus from Pliocene of Italy
Neithea is an extinct genus of bivalve molluscs that lived from the Early Jurassic to the early Paleocene, with a worldwide distribution. [1] Neithia sp. are inequivalve. That means that the two valves are not the same shape, the right valve being strongly concave and the left valve being flattened or concave.
This genus is known in the fossil record from the Carboniferous period to the Eocene period (from about 313.8 to 37.2 million years ago). Fossils of species within this genus have been found in marine sediments all over the world. [1] [2]
