Podcast 304 - Getting the Timing Right
from Palaeo After Dark
The gang discusses two papers that look into the evolution and timing of key morphological innovations within animal groups. The first paper describes possible raptorial appendages in fossil artiopods, and the second paper finds early evidence of modern bird morphologies in the Jurassic. Meanwhile, Amanda gloats, Curt dies, and James eulogizes. Up-Goer Five (Amanda Edition): Today our friends look at two papers where one friend can feel better about how they do the work than how other people do the work. One paper is about big face hand animals with many parts to their legs that use their big face hands to maybe grab and eat other animals. It says that maybe these animals with many parts to their legs all got the big face hand parts in different ways that other animals with many parts that also have the big face hand parts. The other paper is about the animals that do not have hair or hard skin that fly. It says that the animals that do not have hair or hard skin that fly show up earlier than people maybe thought that they did. They are animals that are more like today's animals that do not have hair or hard skin that can fly. One of our friends has said this for a long time and felt good when they saw this paper.
