The gang discusses two papers that look at the complex evolutionary history of sauropod dinosaurs. In particular, these papers try to determine how sauropods geography might have affected their evolutionary history. Also, James learns some valuable lessons about hot tub safety, Curt mindlessly quotes Futurama, Amanda discusses the surprising skills of her cats, and everyone has a deeply disturbing realization about the Flintstones.
Up-Goer Five (James Edition):
This week the group looks at two papers that focus on big stupid angry animals with no hair. Both papers are looking at the type of big stupid angry animals with no hair that were very big and had thick legs and really long necks. The papers are interested in where the big angry animals with really long necks lived, and how where they lived change over time.
The first paper looks at a new big angry animal with a long neck from the place where food is big and people are armed. The reason this animal is interesting is because it is part of a group that was thought to all be dead but the new animal shows that they lived longer than we thought. All the older animals in its group came from a long way away, and so this animal shows that the group lived longer than we thought and that they did so by moving into a new place.
The second paper also looks at a big angry animal with a long neck from the hot place with the long water running through it. This animal is part of a group we find on lots of other places, but not here. This animal shows that the group made it into the very large land where the rains are, even though a different group of animals with very long necks are usually there.
