The gang discusses two papers that detail how the stratigraphic record affects our understanding of the fossil record. Meanwhile, Amanda gets very enthusiastic, James burns straw men, and Curt isn't sorry.

In this episode the gang tries to have a discussion about the fossil preservation of birds. Instead they get completely sidetracked imagining the penguin apocalypse. Meanwhile, Amanda slowly goes crazy, James keeps hearing things, and Curt delights in a mispronunciation.
"Up goer five" text summary
This time the group looks at papers about how animals that have bits that mean they can fly break down when they are dead. The first paper looks at what happens to animals that have bits that mean they can fly when their bodies are left in bad water. These studies are used to see how long animals that could fly were dead before they were covered by stuff in old places where lots of dead things are found in the same place. The study shows that there are fewer types of animals that could fly in these old places where lots of dead things are found in the same place than we would expect. The second paper uses a computer to find out whether we should expect to find all the types of animals that could fly in these old places where lots of dead things are found in the same place. This study shows that we should not expect to find all of the animals that could fly in these old places, but instead that because on the type of old place we should expect to see different types of animals that could fly because of where they lived.
