THE MARINE REPTILE TIMELINE

While the era of dinosaurs is now fairly fixed in the popular consciousness, far less attention is given to the reptiles of the same time period that returned to the sea. While not dinosaurs, these reptiles too reached impressive proportions- and gained traits, like live birth and warm-bloodedness, that we now associate with mammals.

Take my hand and I’ll walk you through the world of seafaring reptiles, all the way back to diminutive Mesosaurus 300 million years ago…

“Atopodentatus unicus” is the freakiest tetrapod I have ever known; a marine reptile with hoof-like claws, a curved upper filled with hundreds of needle-like teeth, and a cleft that splits the upper jaw in two that has teeth inside it like some kind of Lovecraftian, eldritch abomination of evolution.

And I freaking love it.
