Venericardia Bimaculata
''Venericardia'' is a widely distributed genus of marine bivalve molluscs, in the family Carditidae. It is the type genus of subfamily Venericardiinae. The closely related '' Purpurocardia'' was for long included here as a subgenus, but is increasingly considered distinct. Species Species of ''Venericardia'' include: * '' Venericardia amabilis'' * '' Venericardia bimaculata'' * ''Venericardia ferruginea'' * ''Venericardia granulata'' * †''Venericardia imbricata'' (Gmelin, 1791) * †''Venericardia iheringi'' (Boehm, 1903) * ''Venericardia planicosta ''Venericardia'' is a widely distributed genus of marine bivalve molluscs, in the family Carditidae.

Paleocene
The Paleocene, ( ) or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by Chicxulub impact, an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification.
