Podcast 283 - Stolen Podcast

Palaeo After Dark

The gang discusses two papers about an interesting locality in South America and the various body fossils and ichnofossils found in this locality. This podcast originally started as a patreon request to podcast about fossil procyonids… but it ended up like this… ooops!

Meanwhile, James has a vocal doppelganger, Amanda deals with being human, Curt deals with scams, and everyone talks way too much about visuals on an audio podcast.

Up-Goer Five: (Curt Edition)

The friends talk about a place that has rocks from a long time ago that give us an idea of the types of animals that were around in the land areas under where the friends are today. The land where our friends are one used to not be touching the land that is under them like it is now. Once these two lands touched, then the animals from each land moved into the other lands. This place is from a time before these two lands had finished touching, so some animals moved over but others had not yet. The first paper looks at some parts of a type of animals that is brother/sister to animals that grab food out of our place we put food that we can not eat anymore. These animals had moved onto the land under the land our friends are on before the two lands had stopped touching. The place where these parts are found is interesting because it seems like it is under water for some time but there are some bits that are not under water. The first paper shows some marks in the ground that are interesting, but the second paper goes in on these marks to show that they are homes and marks from food searches from other animals. These marks show that the animals in this area were doing a lot of things to make homes and look for food under the ground. This shows that even before other animals moved from the other land, animals in this area were doing cool things in the ground.
