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....

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...

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-G...

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 uph...

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 o...

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 a...

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...

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 t...

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 frie...

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 a...

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 lo...

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 grou...

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...

The gang discusses two papers that look at some exceptional soft-tissue preservation during the Silurian. The first paper potentially identifies a unique type of pterobranch, and the second paper looks at some early molluscs. Meanwhile, James has seen some movies, Amanda has a skibidi day, and Curt's soul dies.   Up-Goer Five (Curt Edition): The friends talk about two animals from a long time ago...

The gang discusses two papers that look at some exceptionally preserved juvenile fossil specimens and the interesting clues these fossils give to the ontogeny of extinct groups. The first paper is the current oldest preserved tadpole, and the second paper is an exceptionally preserved mummified sabre-toothed cat. Meanwhile, Amanda becomes light, James is visited, and Curt is left in the dust and t...

The gang discusses two papers that look at the evolution of photosynthesis in different groups. The first paper looks at what might be the first fossil evidence of thylakoids, and the second paper finds evidence for photosynthesizing symbiotes in Devonian fossil corals. Meanwhile, Amanda is making a lasagna, James has a lot of opinions about lasagna (~10 minutes until we actually get to the paper)...

Sausage, Biscuits, Eggey, and Crankshaft make their way into the big mansion. Will they be able to pull off the heist of the century and deliver a perfect Christmas for the raccoons of the junkyard, or will they all go down in a blaze of glory?

The gang discusses two papers that look at patterns of mosaic evolution, one paper looking at cat evolution and the other paper looking at bird ecomorphy. Which means the gang talks about Amanda's two favorite taxonomic groups. Meanwhile, Curt enjoys some realistic bird calls, Amanda remains a threat, and James provides relevant "facts".   Up-Goer Five (Curt Edition): The friends take a look at ho...

The gang discusses two papers that detail interesting findings about the soft tissues of extinct arthropods. The first paper does a detailed study of the limbs attached to the trilobite head. The second paper describes the newly discovered head of the ancient myriapod Arthropluera , and discusses the larger implications this fossil has for the evolution of millipedes. Meanwhile, Curt explores new...

The gang discusses two papers that look at examples of soft tissue preservation during the Cambrian. The first paper is a deep dive into the sedimentology and paleoenvironment of the Emu Bay Shale. The second paper makes some interesting claims about soft tissue preservation in a marginal marine environment. Meanwhile, James needs some shortcuts, Curt is locked up, and Amanda should be blamed for...

The gang discusses two papers that look at two Lagerstätten (fossil localities of exceptional preservation). The first Lagerstätte is a unique complex early Triassic community found near the equator, and the second Lagerstätte is a collection of exceptional trace fossils from the Pennsylvanian. Meanwhile, James is convinced in the existence of a town that doesn't exist, Amanda takes an unexpected...

The gang looks at two papers that compare similar structures in unrelated animals to see if there might be evidence of convergence. The first paper compares Spinosaurus to phytosaurs and the second paper compares the hyoid bone of ichthyosaurs and toothed whales. Meanwhile, Curt will try it, James waits for something that never happens, and Amanda has a surprise.   Up-Goer Five (Curt Edition): The...

The gang discusses two papers that look at convergence (maybe?) in modern arthropods.
