I can't get over how fantastic these giant moas look and how sad it is to think that they're just one of the few animals portrayed in this show who just existed in their habitat 600 - 500 years ago. 😍😢 🦤

This is why I love paleontology. For over 20 years, I and most of my colleagues were skeptical about the validity of the genus Nanotyrannus. Now, say hello to Nanotyrannus lethaeus. The image below features a pack of these N. lethaeus attacking a juvenile T. rex. Art by Anthony Hutchings.

Cretaceous sea turtle soft tissues clarify ancestry of scale loss in chelonioids
Kear et al. describe the oldest fossil sea turtle soft tissues. These reveal the repeated
evolution of scale-less skin as a hydrodynamic adaptation for oceanic lifestyles in
chelonioids.
