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...

Podcast 318 - Derp Fish Returns
Palaeo After Dark
The gang discusses two papers that provide nuanced information to test when key innovations in vertebrate evolution occurred. The first paper looks at unique semi-terrestrial trace fossils in the early Devonian in order to determine the trace maker, and the second paper looks at fossils that could provide information about the origins of teeth. Meanwhile, Curt has theme park ambitions, James provides Amanda with new anxieties, and Amanda leaves it all to chance. Up-Goer Five (James Edition): The group talk about two papers that are looking at the earliest time things have been seen in...

Podcast 317 - Bring the Brain Power
Palaeo After Dark
The gang discusses two papers that deal with fossil brains. The first paper looks at a fossil arthropod from the Cambrian and uses neurological characters to determine its phylogenetic placement. The second paper looks at a synapsid braincase and tries to infer why this one species has lost its parietal eye when other members of the species have he eye. Meanwhile, Curt invents some new sponsors, Amanda has plans for James, and James discusses some personal growth. Up-Goer Five (Curt Edition) The friends talk about two papers that look at very old brains in animals that are long gone....

Podcast 316 - Sail Back Bros
Palaeo After Dark
The gang discusses two papers about skin preservation in fossil tetrapods. The first paper describes skin impressions from a Permian synapsid, and the second paper identifies feather-like structures in an early Triassic diapsid. Meanwhile, James considers the horse, Amanda shames extinct animals, and Curt quotes “philosophy”. Up-Goer Five (Amanda Edition): Today our friends talk about things that are sort of close to things with hair but not that close to things with hair. They are closer to things with hair than to things with dry skin with no hair or long many-part skin things....

Podcast 315 - Final Transmission from the Black Lodge
Palaeo After Dark
The gang ends “Wet Hot Archosaur Summer” with the final podcast recorded from our undisclosed location in the woods. For this podcast, we indulge Amanda by talking about birds and trace fossils. The first paper looks at the remains of nesting sites that date back to the Cretaceous, and the second paper investigates sources of error in estimates of avian maximum speeds from trace fossils. Meanwhile, Amanda has a message for the bears, James proposes an alliance with the crows, and Curt does an “homage”. Up-Goer Five (Curt Edition): The friends talks about two papers that will...

Podcast 314 - Weird Archosaur Summer
Palaeo After Dark
The gang is all back together in one place again as they unite in an undisclosed cabin in the woods to record the last two podcasts for Wet Hot Archosaur Summer. For this episode, the gang talks about herbivorous pterosaurs and wadding T-rex. Meanwhile, James experiences relative sobriety, Curt welcomes everyone to the Great Northern, Amanda is fueled by spite, and we all get completely off track. Up-Goer Five (Curt Edition): The friends are together for the first time in a long time and so they have a lot of fun together and sometimes they talk about a paper or two. The first paper...

Podcast 313 - Ooooo Banana
Palaeo After Dark
Wet Hot Archosaur Summer continues as the gang discusses two papers that look at the evolution and biogeography of early archosaurs. Specifically, one paper describes new material from an early dinosaur group, and the other paper looks at the niche preferences of early pterosaurs and their closest sister group, the lagerpetids. Also, James tries out a new flavor, Curt likes consistency, and Amanda provides some ASMR. Up-Goer Five (Curt Edition): The friends look at two papers about the early types of animals that would give us lots of different types of big angry animals like the big...

Podcast 312 - Sick Skateboard Tricks
Palaeo After Dark
The gang discusses two papers about the ecology of sauropods. The first paper investigates the biomechanics of the Plateosaurus tail, and the second paper looks at direct evidence of sauropod diet from gut contents. Meanwhile, James “makes it interesting”, Amanda may have recorded on the wrong microphone, Curt makes a bold rebrand, and everyone vaguely remembers “Denver: The Last Dinosaur”. Up-Goer Five (Curt Edition): The friends talk about two papers that look at animals with along necks from a long time ago that kids love and were in a movie where one of them called Little...
info_outlineWet Hot Archosaur Summer continues as the gang discusses two papers about crocodylomorph evolution. The first paper looks at the impact mass extinctions had on disparity within the group, and the second paper uses new phylogenetic data to revise our understanding of size trends and biogeography of crocodylomorphs during the Cenozoic. Meanwhile, Curt invents a measurement, James invents a new way of eating, and Amanda invents a new phobia for herself.
Up-Goer Five (Curt Edition):
The friends talk about two papers that look at big angry animals that you should never smile at, again! This time they are looking at very old big angry animals you should never smile at. The first paper looks at how different these animals were in the past and looks at how different they are today. A lot of people think that the big angry animals today are not as different than they were in the past and that this might be weird. The paper finds that these big angry animals have been more different in the past, but that the animals today are not so much the same as each other in a weird way. There were times in the past where these animals were as different from each other as we see today, and they even got more different again after that.
The second paper looks at a new way of thinking about two animals from the past that were really big and you really should not smile at. These animals were thought to be part of this one group that is not as big today and also would be really weird because these some of these animals in the past are found across the big blue wet thing and we do not think that they can move across that big blue wet thing because of the stuff that is in the big blue wet thing that is not water that makes your food good. This paper shows that these big animals are probably not in that group, and so they use this to see what this means about where this one group of animals was living and how they got smaller.
