Podcast 324 - Pick Up the Pieces
Palaeo After Dark
The gang discusses two papers that use fragmentary fossils of animals to investigate the origins of major groups. The first paper describes an Early Ordovician eurypterid, and the second paper looks at mosaic evolutionary patterns in an early squamate. Meanwhile, James has bird opinions, Curt delights in not knowing, and Amanda will definitely be on time. Up-Goer Five (Curt Edition): The friends look at two papers that are using broken bits of things to learn a lot about animals from a long time ago. Both of these papers are looking at old animals that may give us new looks at how big...

Podcast 322 - Obligatory Dinosaur Podcast 3: Dino With a Vengeance
Palaeo After Dark
The gang discusses two papers that are about dinosaurs, and that is all that connects them! The first paper investigates community structure during the Cretaceous, and the second paper describes a well preserved “mummy” of a duck-billed dinosaur. Meanwhile, Amanda is doing well (really she is now), Curt makes an awkward segue, and James has not seen Tremors. Up-Goer Five (Curt Edition): The friends talk about two papers about big angry animals from a long time ago. The first paper looks at how many types of big angry animals were in a place before something bad happened and all the...

Podcast 321 - Getting Mostly Stems Here
Palaeo After Dark
The gang discusses two papers that have very little in common with each except for the word “stem”. The first paper uses birth death models to simulate the fossil record in order investigate if neutral models can produce patterns similar to the “crown”/“stem” evolutionary dynamics that have been observed in real data. The second paper investigates stem mandibulate fossils to investigate the timing of major key innovations in the evolutionary history of this arthropod group. Meanwhile, Amanda decides, James bullies, and Curt explains. Up-Goer Five (Curt Edition): The friends...

Podcast 320 - von Herrerasaurus
Palaeo After Dark
The gang discusses two papers that investigate injuries in fossil bones. The first paper tests hypotheses about the causes of facial injuries in herrarasaurids, and the second paper tests if inferred hunting strategies map onto injury patterns in predators from the La Brea Tar Pits. Meanwhile, Curt provides some hypotheses, Amanda gets spiritual, and James is photogenic. Up-Goer Five (Curt Edition): The friends talk about two papers that look at why animals from a long time ago got hurt. The first paper looks at some very old and angry animals with no hair that all got hurt in the...

Podcast 319 - CSI Crato Formation
Palaeo After Dark
The gang discusses two papers that use taphonomic experiments to test hypotheses about the paleo-environmental conditions of the Crato Formation. Meanwhile, Amanda has her daily requirements, James longs for the rack, Curt launched a new podcast concept, and no one on this podcast can keep to a topic for longer than five minutes. Up-Goer Five (Curt Edition): The friends talk about two papers that look at rocks that come from the same place. This place is a spot where you get a lot of soft things from animals in the rocks which would usually not be able to be in the rocks because they...

Up-Goer Five (Curt Edition):
The friends talk about two papers that have very little to do with each other, other than the fact that they have one of the same words in them. The first paper looks at the ways in which animals change over time and how they make more of each other and how the ways things live and die can make it look like there are some groups that do better than others. The paper shows that some of this is something we should see even if it is just because of how things make more things and the fact that we care more about the things that live today than the things that do not live today.
The second paper looks at how animals that have many parts that repeat make their arms and legs. This paper looks at very very old animals from groups that are not around today but maybe could be close to those groups. The group of animals today that this group is close to has a lot of things that all of them share, like that they make mouths from a lot of arms, and also they have things on the front they use to feel things, and that they are three parts. This paper is using these old animals that are close to this group to try and see which things today in this group appeared first, and which things may have taken some time before they appeared.
