Titanoboa - Cenozoic Era

Extinct Animals Daily Challenge #1027: Aug 4, 2025

"Cenozoic Era" is also known as the Age of Mammals (Titanoboa lived in the Paleocene epoch)

Estimated up to 50 feet long and 3 feet wide, this snake was the top predator in the world's first tropical rainforest (the territory of today's Colombia). It was also the largest known predator on the planet between the extinction of dinosaurs 65 million years ago and the first appearance of Megalodon ~23 million years ago.

Titanoboa died out around 58 to 60 million years ago, so its dominance was fairly brief in geological terms. Scientists aren't quite sure, but they believe that climate change had something to do with it. The climate started to cool, and the enormous snake and other large reptiles couldn't maintain their metabolism.
