Podcast 300 - Shameless Dead Juvenile Specimen Joke
Manage episode 463209543 series 73318
The gang discusses two papers that look at some exceptionally preserved juvenile fossil specimens and the interesting clues these fossils give to the ontogeny of extinct groups. The first paper is the current oldest preserved tadpole, and the second paper is an exceptionally preserved mummified sabre-toothed cat. Meanwhile, Amanda becomes light, James is visited, and Curt is left in the dust and the filth.
Content warning: This episode contains covers some potentially dark material given that these fossils are juveniles. The following time stamps represent some of the more sensitive moments in which the group make morbid jokes about the subject matter.
6 min 3 sec to 6 min 39 secs.
58 min 13 seconds to 58 min 29 secs
Up-Goer Five (Curt Edition):
The friends talk about two papers that show some kids from animals groups that are no longer around. These papers are cool because they show how animals from a long time ago changed as they got older. The first paper looks at the kid of an animal group that changes a lot from a thing that moves through water to a thing that jumps on the ground. This kid is somewhere in the middle of jumping and moving through water. This is the oldest of this type of kid we have found so far. The group today is different because they go through this really big change. This paper shows that they were going through this really big change a long long time ago and shows that this change probably happened early on in their time line.
The second paper looks at a kid that is from a group of animals with hair and long teeth. This kid was in ice and so we have a lot of things that we would not get that are soft. This is the first time we have seen the soft parts for this age of this animal and it shows us that lots of things we see in the grown animals were also there when they were kids.
