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...

Podcast 306 - Birbs Grinding on the Edge of the Pareto Front
Palaeo After Dark
The gang discusses two papers that use morphometrics to investigate patterns of selection on bird morphology. The first paper looks at the morphology of feathers, while the second paper looks more broadly at various parts of the avian body. Meanwhile, James breathes new life into a classic, Amanda is passionate about formatting, and Curt exposes “the truth”. Up-Goer Five (Curt Edition): The friends talk about two papers that look at animals that move in the air. Both of these papers look at how these animals look and try to find out why these animals look the way they do. The first...

Podcast 305 - Skin in the Game
Palaeo After Dark
The gang discusses two papers that look at preserved skin/external tissues. The first paper shows a unique record of Cambrian molting, and the second paper looks at the first preserved samples of plesiosaur skin. Meanwhile, Amanda commits an "own goal”, Curt shares some old internet fun, and James has opinions about fins. Up-Goer Five (Curt Edition): The friends talk about two papers that look at skin that is very very very old. The first paper looks at animals from a long time ago that lose their skin when they get too big for it when then grow. They found these parts on the skin...

Podcast 304 - Getting the Timing Right
Palaeo After Dark
The gang discusses two papers that look into the evolution and timing of key morphological innovations within animal groups. The first paper describes possible raptorial appendages in fossil artiopods, and the second paper finds early evidence of modern bird morphologies in the Jurassic. Meanwhile, Amanda gloats, Curt dies, and James eulogizes. Up-Goer Five (Amanda Edition): Today our friends look at two papers where one friend can feel better about how they do the work than how other people do the work. One paper is about big face hand animals with many parts to their legs that use...

Podcast 303 - When Is It The Crown
Palaeo After Dark
The gang discusses two papers that look into the timing of evolution of the “crown group”. The first paper looks at fossil glass sponges, and the second paper looks at the phylogeny of lampreys. Meanwhile, James gives some sound advice, Amanda has ambitious hobby plans, and Curt imagines the perfect media crossover. Up-Goer Five: (Curt Edition) The friends talk about two papers that look at groups of animals and try to see when the things that we see today in these groups may have first happened in the past and what we can tell us about why those things might have happened. The...

Podcast 302 - A Rambling Homage to Vrba
Palaeo After Dark
The gang celebrates the research of the late Elisabeth Vrba by talking about two of her papers, as well as her research more broadly. And, despite their best efforts, they get easily distracted on tangentially related side discussions. Up-Goer Five (Curt Edition): The friends talk about two papers from someone who they want to remember the memory of because that person is no longer with us. They talk a lot about this person's work, and some other things that come up as they are talking. The big things these two papers look at are how small things working together can build things that...
info_outlineThe gang discusses two papers that investigate evidence of symbiosis in the fossil record. The first paper looks at wormy organisms living inside Cambrian vetulicolians, and the second paper shows potential evidence of hydroids growing in mollusc shells. Meanwhile, Amanda is haunted, James’s computer is totally cooperating, and Curt may or may not have had to stitch this podcast together from other sources.
Up-Goer Five (Curt Edition):
The friends look at two papers that look at animals that live inside of other animals. Sometimes these things live inside other things and both of the things do well because of it. Sometimes, these things live inside other things and they cause problems for the thing they live in. These two papers look at the ways we can see old bits of things that used to live in other things and how we can try and figure out why they might have lived inside other things. The first paper looks long animals living inside a weird animal from a long long time ago. These long animals are all in a small part of these animals that looks like where these weird animals would breathe. Many long animals live inside one of these weird animals. The second paper looks at how hard parts of animals grow over things trying to live on them and we can use use the way these things grow to get an idea of what could have been living on them.
