Palaeo After Dark

The gang discusses two papers that look at interesting new arthropod fossil finds. The first paper is the discovery of a new early arthropod which complicates our understanding of their evolution, and the second paper is a large deposit of trace fossils which could be caused by mass arthropod molting. Meanwhile, James has issues with formatting, Amanda's cat is a butt, and Curt has some important...

This year, we're peeling back to curtain to give everyone a peak at how we build our holiday fiasco episode. Join us as Curt, James, Amanda, Aly, Brendan, and Antony build up the characters and start forming the main conflicts for our holiday episode, "Mars Incorporated".

The gang discusses two papers that examine the roles of competition, biogeography, and niche evolution in macroevolution. The first paper looks at the expansion of angiosperms and correlates it with the extinction of gymnosperms, and the second paper looks at the complex ways the Great American Interchange affected niches in South America. Meanwhile, Amanda goes for the eyes, James has a device, a...

The gang discusses two papers about things with legs…. and the word snake is their name. Honestly, we've had flimsier excuses for a podcast, just go with it. The first paper looks at a specimen of a legged snake, and the second paper discusses potential evolutionary pathways for convergent evolution in a group of penguin like animals closely related to snake birds (Plotopterids). Meanwhile, Amanda...

The gang celebrates hitting the milestone of 200 podcast episodes by returning to a topic related to their first episode, sharks. The first paper looks at how shark size has changed through time, and the second paper looks at the different ways whirl-toothed sharks were able to eat their food. Meanwhile, James has ideas about the success of Disney movies, Amanda comes back at the wrong time, Curt...

The gang discusses two papers that look in detail at examples of convergence in the fossil record. The first paper uses multivariate statistics to create an "eco-space" in order to study how ecological roles of marine tetrapods changed over the Mesozoic. The second paper looks at the evolutionary history and functional morphology of sabre-teeth in mammals. Meanwhile, James tries a new flavor, Aman...

The gang discusses two papers about interesting finds in the bones of fossil vertebrates. The first paper looks at the evolution of bony parts in early fishes, and the second paper shows a fascinating example of ontological change in a species of sauropod dinosaur. Meanwhile, Amanda's best ideas are ignored, James has unconventional bread opinions, Curt offers some advice, and everyone spends thei...

The gang discusses two papers that investigate niche partitioning and the ecological impacts on bird beak evolution. Honestly, this podcast is just a grab bag of different topics loosely connected together as an excuse for James to continue to espouse his beliefs on pies. The gang discusses one paper about a long necked reptile and another paper about beak morphological evolution in Aves. Meanwhil...

The gang discusses two papers that look at the wealth of information left behind on fossil bones which can let us know about the many organisms which worked to break down and decay dead animals. These feeding traces give clues to the presence of animals that might not easily fossilize. Plus, this topic is an excuse for James to suggest two papers that involve dead dinosaurs. Meanwhile, Curt starts...

The gang discusses two papers that use the trace fossil record to give us a more detailed understanding of the impacts of mass extinctions. Meanwhile, Curt has a new CSI, Amanda has too many synapsids, and James "understands comedy".   Up-Goer Five (Curt Edition): Our friends talk about the marks that feet make on the ground and how these marks can tell us about things that died when really bad th...

The gang discusses two papers about the ecological data that we can learn from looking at trace fossils. The first paper looks at a unique ancient crocodilian behavior, and the second paper shows similar shore bird behaviors over the course of tens of millions of years. Meanwhile, James is full of bones, Amanda is honored, and Curt loves Hanna Barbera.   Up-Goer Five (Amanda Edition):  Today our f...

The gang discuss two papers that describe unique animal fossils which have been known but haven't (until now) been formally described. The first is "Collins Monster", a lobopod from the Cambrian, and the second is a fossil dolphin which is similar to an orca. Meanwhile, James rehabilitates some dolphins, Amanda saw a thing, and Curt witnesses true beauty.   Up-Goer Five (Amanda Version):  Today ou...

Hey now, you're an all-star, get the game on, go play. Hey now, you're a rock star, get the show on, get paid! All that glitters is a long discussion about Mesozoic eggs. One of the papers we discuss suggests that the evolution of hard calcification in dinosaur eggs might have evolved independently multiple times. The second paper tries to determine the origins of a cryptic large soft-shelled egg....

The gang discusses two papers that look at important points in the evolutionary history of land plants. The first paper is a review of the available data for the first time plants moved onto land in the Ordovician, and the second paper looks at the impact that the evolution of herbivory had on plant diversity. Meanwhile, James invents a new insect, Amanda reaches out and touches someone, and Curt...

The gang discusses two papers about arthropod evolution and development. One paper focuses on the evolution of arthropod segmentation, and the other summarizes research on the development of the insect wing. Meanwhile, Amanda has a beer with no unintended consequences, Curt makes a shocking discovery about marketing, and James goes from 0 to professional in milliseconds. As we did last time, here...

(Editor's Note: This episode was recorded a month ago. Everyone at Palaeo After Dark stands with the protesters fighting for justice. Black Lives Matter!) The gang discuss two papers about large mammal-like animals. The first is a Triassic synapsid the size of an elephant, and the second is a mammaliaform from the late Cretaceous of Madagascar. Meanwhile, James has a new technology to discuss, Ama...

The gang discusses two papers about archosaurs. The first paper looks at the trends in brain size relative to body size in birds over their entire evolutionary history. The second paper revisits the dinosaur Spinosaurus and adds more information to the debate over whether this animal had a semi-aquatic lifestyle. Meanwhile, James has some villagers he needs to "un-person", Curt gives alternative d...

The gang discusses two papers about unique taphonomic conditions. One paper describes how these strange "train wrecks" of crinoid columnals might have formed, and the other paper models how bone jams in Dinosaur National Park could have formed. Meanwhile, James's computer has a flux capacitor, Amanda mishears the best new BBC crime drama, and Curt enjoys the chance to talk about Nathan Fillion veh...

The gang discusses two papers that look at modifications of the vertebrate hand. The first looks at how the lobe fin evolved into the vertebrate hand, and the second paper looks at the early limb transformations of early whales as hands became fins. Meanwhile, James's computer is a time traveler, Amanda is upset that everyone is upset about Bunny Day, and Curt wonders about numbers higher than 10....

That gang discusses two papers about fossil soft-bodied Cambrian organisms; one of which is a unique lobopod and the other is a fossil worm. Meanwhile, Amanda could go for some fish, Curt can't stop the puns, James is going to be a cowboy.   Up-Goer Five (James Edition): This week the group looks at two papers that are looking at two very old animals that have long bodies with no legs. One of thes...

The gang talks about two papers which look at the ecology of the Ediacaran. One paper uses trace fossils to infer how ecological systems change as we move from the Ediacaran to the Cambrian, and the second paper identifies some interesting features previously undocumented in Ediacaran fossils. Meanwhile, Curt has ideas about sponges, the internet destroys James's comedic timing, and Amanda is happ...

The gang discusses two papers that look at the human impact on the fossil record. The first paper runs multiple model studies to try and determine when hominines (the group that includes all of our ancestors) first began significantly impacting the biosphere. The second paper estimates what our future fossil record may look like by using the state of Michigan as a model system (much to Amanda's de...

The gang celebrates their 7th anniversary by inflicting pain on themselves for your amusement by discussing a classic paper, Gould's "Paradox of the First Tier". They discuss the paper in its historical context, and also how our knowledge of mass extinctions has changed and evolved from this paper. Meanwhile, James comes up with unconventional ways to communicate, Amanda may need some more whiskey...
