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...

Podcast 311 - On a Wing and a Trace
Palaeo After Dark
The gang continues “Wet Hot Archosaur Summer” with a discussion about pterosaur trace fossils. The first paper tests a method for assigning pterosaur traces to potential trace makers, and the second paper is a case study of actually assigning traces to a species. Meanwhile, Amanda herds cats (figuratively and literally), James can only accomplish three things, Curt keeps it light, and everyone upholds their “journalistic integrity”. Up-Goer Five (Curt Edition): The friends talk about two papers that look at the marks that animals leave on the ground. These marks are made by...

Podcast 310 - This Podcast Is Two Darth Vaders Tall
Palaeo After Dark
Wet 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...

Podcast 309 - Wet Hot Archosaur Summer Begins
Palaeo After Dark
The gang kicks off a summer of archosaurs by talking about crocodyliforms. The first paper describes an early Cenozoic large notosuchian, and the second paper investigates how cryptic species impacts divergence times within the clade. Meanwhile, Curt diagnoses a problem, James tries to “help”, and Amanda does not care. Up-Goer Five (Curt Edition): The friends talk about two papers that look at animals that today most of the time live in water and grab food from the edge of the water and you should never smile at. The first paper a really big one of these animals that lived a long...

Podcast 308 - Failing to Talk About the K/Pg Mass Extinction
Palaeo After Dark
The gang tries to discuss two papers that look at the evolutionary impacts of the K-Pg mass extinction. Specifically, they look at one paper that estimates sampling probability throughout the late Cretaceous to determine if record bias influences our understanding of the extinction, and another paper that looks at species area relationships to investigate ecological shifts in response to the event. However, the gang gets completely lost and sidetracked throughout. They starting talking about the papers around 18 minutes in… and very quickly lose track again. It’s going to be one of those...

Podcast 307 - Glow in the Dark Shrew Jorts
Palaeo After Dark
The gang discusses two papers that look at the evolutionary impact of shifts in habitat occupation. The first paper looks at a clade of sharks moving into the depths, and the second paper investigates habitat shifts in mammals across the Cretaceous and Paleogene. Meanwhile, Amanda has some opinions, James is doing much better, and Curt is easy to amuse. Up-Goer Five (Curt Edition): The friends talk about two papers that look into how animals change when they move from one type of place to another. The first paper looks at animals with big teeth that has soft parts inside and live in...
info_outlineThe gang discusses two papers that look at patterns of niche conservatism or niche evolution in the fossil record. The first paper looks at the pollen records of trees in Portugal to test if changing climate can explain modern tree distributions, and the second paper looks at the impact of Late Devonian extinction pulses/invasions on brachiopod communities. Meanwhile, Curt summarizes the podcast, James has brachiopod facts, and Amanda cannot control her cats.
Up-Goer Five (Curt Edition):
Our friends talk about two papers that look at where animals live and what they do in the world, and also if that stays the same or changes over time. The first paper looks at tall living things that make their own food and lose a part of themselves every fall. This looks at one place that has just a few of these types of living things but in the past there were different types there. Also, back then it was not as warm and the rain was different. This paper wants to see why the tall living things we have in this part of the world are where they are right now. What they saw was that, some of the changes in the tall things seem to be tall things following where they want to live; when things get warmer or colder they move to follow the change. But some things seem to be moving into places that are very different from where they started, so they are changing what types of places they like to live in.
The second paper looks at animals that live on the bottom of the big blue wet thing and take food out of the water and were found all over the world a long time ago. It looks at a time when a big change killed a lot of living things. This paper looks at how this changed the types of these animals over time. What they find is that, a lot of the animals that die because of the change have another animal from somewhere else doing the same thing move in and take that animal's place. The things that do not die just keep on doing their own thing. It does not look like there is much change in what the animals are doing either from the big change that happened, or from the new animals moving in.
