The K-Pg extinction event, brought on by an asteroid impact and an ensuing impact winter, marked the beginning of the Paleocene and killed off 75% of life on Earth, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene\u2013Eocene thermal maximum, which was a major climatic event wherein about 2,500\u20134,500 gigatons of carbon was released into the atmosphere and ocean systems en masse, causing a spike in global temperatures and ocean acidification.\n\nThe Paleocene continued many geological processes initiated in Mesozoic, and the continents continued moving towards their present positions.

In the oceans, the thermohaline circulation probably was much different than it is today, with downwellings occurring in the North Pacific rather than the North Atlantic, and water density was mainly controlled by salinity rather than temperature.\n\nThe extinction event caused a floral and faunal turnover of species, with previously abundant species being replaced by previously uncommon ones.
