The Paleocene-Eocene Thermal Maximum (PETM) at 56 million years before present is arguably the best ancient analog of modern climate change. The PETM involved more than 5 o C of warming in thousand years (actually a little slower than rates of warming over the last 50 years), fueled by the input of more than gigatons (a gigaton is a billion tons!) of carbon.

The Paleocene-Eocene Thermal Maximum (PETM) was a period of natural global warming that took place almost 56 million years ago. It came at a time when the atmospheric concentration of CO2 was already higher than today, and global temperatures also much warmer.

The PETM warming was a roughly ,year long event where global temperatures rose by a further. The nonmarine phase of Eocene cycles consists primarily of a lower arenaceous unit and an upper argillaceous unit.

The new species is stratigraphically well constrained and probably represents the youngest known species of the genus, extending its geological record into the Middle Eocene.
