S12DB22 Was T. rex Feathered? What the Fossils Really Tell Us

Were pachycephalosaurs really headbutting each other? Could they have been covered in fuzzy filaments? And does the evidence for scaly skin mean that T. rex was definitely not feathered?

In this Dinosaur Bite, Iszi Lawrence and Dr Dave Hone get into the details of dinosaur skin, from the healed injuries on thick-skulled pachycephalosaurs to the mysterious patterns preserved in tyrannosaur fossils. Dave explains why what looks like a scale is not necessarily a scale, and why we still have a lot to learn about the coverings of many dinosaurs.
We also hear about the challenges of preserving delicate fossil evidence. Sometimes palaeontologists have to make difficult decisions about what to save, and occasionally that means deliberately breaking bones to get a fossil out of the ground in one piece. It's a reminder that the fossil record is shaped not only by what nature preserves, but also by what researchers can recover.
