The gang discusses two papers that look at fossils of the early whale group Basilosauridae. Specially, these papers describe the largest whale recovered from this group, as well as the smallest whale from the group. Meanwhile, Amanda has a lovely home, James has some whale facts, and Curt has some art critiques.

Up-Goer Five (Curt Edition):

The friends talk about two papers that look at one group of big animals that breathe air but move in the water that are no longer around today. These papers are looking at different animals within the same group. The cool thing about both of these papers is that they talk about the same thing, but from different ways of looking at it. This is because one of these papers is about the biggest animal that people have found in this group and the other paper is about the smallest animal found in this group. This is a big thing because this is a group that today has gotten really big and the reasons why these groups get big has been something people are really interested in. These papers show that these animals were getting both big and small very early on in the group.
