The gang discusses two papers that look at examples of soft tissue preservation during the Cambrian. The first paper is a deep dive into the sedimentology and paleoenvironment of the Emu Bay Shale. The second paper makes some interesting claims about soft tissue preservation in a marginal marine environment. Meanwhile, James needs some shortcuts, Curt is locked up, and Amanda should be blamed for everything that happened here.

 

Up-Goer Five (Curt Edition):

The friends look at two papers that look at animals from a long long time ago that lived in the water and were soft but were able to be found in rocks. The first paper looks at a place where there are a lot of animals found in rocks but the types of animals are different from other places around the same time. This paper looks at what the place was like at that time and they see that this was a place where a long line of water that you can drink made its way into the big water that you can not drink. The second paper made us all sad.
