Around 56 million years ago, rapid global warming sparked the PETM. Early primates like the tiny Archicebus (from China, weighing under 1 oz) spread across the Northern Hemisphere. Teilhardina and Cantius were other early primates with adaptations for climbing. 🌍🔥
First true primates emerged during PETM 56 million years ago
Key facts
- The earliest true primates appear around 56 million years ago during the PETM (Paleocene-Eocene Thermal Maximum)
- The PETM was a period of rapid global warming 5-8°C over a few thousand years
- During the PETM, the Arctic had subtropical swamps with palm trees and crocodiles as far north as Saskatchewan
- Early primates like Aribbus (from China) weighed less than 1 ounce
- Cantius and Talhardina are other early primates with adaptations for climbing
- These early primates were widespread across the Northern Hemisphere
- Finding earlier primates is difficult because features didn't evolve all at once and tiny animals fossilize poorly
