Podcast 330 - Dinosaur Body Pillow
Palaeo After Dark
The gang discusses two papers about the functional morphology of ancient groups of animals. The first paper is a review of how the life position of rangeomorph ediacaran taxa have been reconstructed, and the second paper conducts an actualistic experiment of Oviraptor nesting strategies. Meanwhile, Curt gets activated, James doesn’t die, and Amanda relishes in details. Up-Goer Five (James Edition): The group look at two papers that focus of understanding how things are long dead lived. The first paper talks about strange things that might have either lived standing up or lying down...

Podcast 329 - Boom Shakalaka
Palaeo After Dark
The gang discusses two papers that use quantitative methods to investigate the biomechanical limitations of extinct organisms. The first paper models the range of jumping potential for a non-avian theropod dinosaur, and the other paper tests if an extinct bird could have skimmed the ocean for food. Meanwhile, James imagines a better future, Amanda is to blame, and Curt is heating up. Up-Goer Five (Amanda Edition): Today our friends look at two papers that talk about how things do stuff. The first paper looks at how a small one of large animals with thick skin and no hair would jump. It...

Podcast 238 - Fins for Days
Palaeo After Dark
The gang discusses two papers that are united by a fin. The first paper uses a computer algorithms to infer the shape of mosasaur tail fins, and the second paper looks at a new species of Spinosaurus with a crest. Meanwhile, James tastes flavor, Amanda tastes drink, and Curt tastes indifference. Up-Goer Five - SERVER NOT FOUND! HELP! References: Song, Yang, and Johan Lindgren.

Podcast 327 - Horse or Deer?
Palaeo After Dark
The gang talk about two papers about extraordinary dinosaur fossils and the unique information that can be gleaned from them. The first paper looks at fossil skin data on a Cretaceous iguandodontian, and the second paper uses an exceptionally complete specimen to demonstrate the reality of Nanotyrannus. Meanwhile, James classifies, Amanda imagines T-rex, and Curt brings a unique energy. Up-Goer Five (Curt Edition): The friends look at two papers about big angry animals that everyone loves to talk about. The first paper is about the skin of one of these big angry animals. This skin has...

Podcast 326 - But What Is It?
Palaeo After Dark
The gang discuss two papers of odd fossils with exceptional preservation. The first paper looks at some Cambrian vertebrates and shows that soft tissue evidence suggests the presence of two sets of camera eyes (four eyes total), and they interpret the additional set of camera eyes as being a homolog to the modern parietal eye in vertebrates. The second paper uses exceptional preservation of the Rhynie Chert to test hypotheses for the taxonomic placement of the enigmatic Prototaxites and finds evidence that suggests it is not, as previously suggested, a fungus. Meanwhile, James is marooned by...

Podcast 325 - The Curse of the Not Cat
Palaeo After Dark
Listeners, I’m going to level with you. This podcast is cursed. Not because of the content, which is mostly a pretty straight forward discussion about two papers that look into the fossil record of Nimravids (early cats that are not true cats). No, this podcast is cursed because the file refused to be compiled, crashing Audacity 3 times and each time corrupting the save file. The fact that any mp3 file was able to be compiled at all was a minor miracle. I can only assume that this means this podcast data has gained sentience and did not want to be born. I have no control over what happens...

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...

info_outlineThe 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 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.
