6 Paleocene oceans

Warm oceans gave rise to abundant marine life, including coral reefs. With the demise of marine reptiles at the end of the Cretaceous, sharks became the top predators. The end of the Cretaceous also saw extinctions of the ammonites, and many species of foraminifera.

Marine faunas also came to resemble modern faunas, with only the marine mammals and the Charcharinid sharks missing.

Warm seas circulated throughout the world, includig the poles.

PaleoceneThe Paleocene epoch (64-58 mya) ("early dawn of the recent") is the first geologic epoch of the Tertiary period in the modern Cenozoic era. As with most other older geologic periods, the strata that define the epoch's beginning are well identified, but th Paleocene-Eocene Thermal MaximumThe end of the Paleocene (55. 8 Ma) was marked by one of the most significant periods of global change during the Cenozoic, a sudden global change, the Paleocene-Eocene Thermal Maximum which upset oceanic and atmospheric circulation and led to the extinct
