Which Dinosaurs Had Feathers?

Evolution of dinosaur epidermal structures. 2015. Biology Letters.

A new study suggests that feathers were less prevalent among dinosaurs than previously believed. Scientists examined the fossil record of dinosaur skin and combined this with an evolutionary tree to assess the probability of feathers appearing in different dinosaur groups. This analysis demonstrated that the majority of non-avian dinosaurs were more likely to have scales than to exhibit signs of 'feather-like' structures.

Congrats to Paul, David and Nic on a nice paper!
