The gang discusses two papers that look at the fossil frog record. The first paper identifies fossil frogs from Antarctica, and the second paper looks at some exceptional soft-tissue preservation. Meanwhile, James has ideas for expanding the brand, Amanda asks for clarification on an important topic, and Curt makes some executive decisions.

Up-Goer Five (James Edition):

The group looks at two papers that are interested in animals that are wrong and good at jumping and live in the water but some can walk on land and climb trees. The first paper is looking at one from the very cold land in the bottom of the round thing we live on, where we do not find any of them today because it is too cold. The animal is known by two small bits but we can tell what type of jumping thing it is and so we know it is part of a group that is found in two areas that do not touch today, but the place at the bottom of the round thing we live on is between them, so that makes sense! But it is very cold today, so that is strange, but the animal being there and the things we find with it seems to show that is must have been a little hotter then.

The second paper is looking at one of the animals that is good at jumping that is found with lots of round things that become babies in it. This is very cool because the animal is also still soft in places in it that means it was not the most grown it could be and so was making babies when it was still young. There is also a thought that the animal may have died while trying to make babies which is interesting.
