Dosinia Glauca
''Dosinia'' is a genus of saltwater clams, marine bivalve molluscs in the family Veneridae, subfamily Dosiniinae Deshayes, 1853. The shell of ''Dosinia'' species is disc-like in shape, usually white, and therefore is reminiscent of the shells of Lucinid bivalves. The genus is known from the Cretaceous to the Recent periods (age range: 99.7 to 0.0 million years ago). Fossils of species within this genus have been found all over the world. Species Extant and extinct species within this genus include: * '' Dosinia abyssicola'' T. Habe, 1961 Indo * '' Dosinia acetabulum'' Conrad 1832 † * '' Dosinia acetabulum'' thori Ward 1992 † * '' Dosinia africana'' Gray 1838 * '' Dosinia alta'' (R. W. Dunker, 1848) Red Sea * '' Dosinia altenai'' Fischer * '' Dosinia amphidesmoides'' (Reeve, 1850) Indo * '' Dosinia angulosa'' Philippi, 1847 Pacific * ''Dosinia anus'' (Philippi, 1848) * '' Dosinia aspera'' Reeve, 1850 Indo * '' Dosinia bilunulata'' (Gray, 1838) Indo * '' Dosin ...

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...
