Podcast 171 - Birds Get Swole in New Zealand

Palaeo After Dark ·

2019/09/15

The gang discusses some very interesting papers about bird fossils in New Zealand. These papers describe how many different types of birds ended up on New Zealand throughout the Cenozoic, and each time they experienced significant increases in their size. Sadly, since this was a very straightforward topic, no one could quite manage to focus on anything. So meanwhile, Curt remembers childhood animations that no one cares about, James makes it “fun” for himself and no one else, Amanda drinks the

Podcast 170 - The Impact of Taphonomy; On Conodonts...

Palaeo After Dark ·

2019/09/01

The gang discusses two very different papers that are sort of united together based upon the importance of taphonomy. First, they look at a paper about how the ways in which conodont elements are preserved can affect our understanding of their evolution. Second, they talk about the recent finding of exceptionally preserved therizinosaur dinosaur nesting sites. Meanwhile, Amanda finds herself dealing with a failing webcam, Curt enjoys burying the lede, and James is never wrong unless he wants to be

Podcast 169 - Learning about Agnostids

Palaeo After Dark ·

2019/08/18

The gang takes some time to discuss two papers about agnostids, a strange group of trilobite-like arthropods whose evolutionary history has been the subject of considerable debate. First, we discuss a short paper summarizing the history of the agnostid debate, and then we discuss a brand new paper using new material and Bayesian phylogenetics to offer a fresh new hypothesis. Also, James channels frustration into fun, Amanda nearly has her house destroyed by cats, and Curt asks the Star Wars

Podcast 168 - Alligator Teeth and Too Small Cats

Palaeo After Dark ·

2019/08/04

The gang discusses two papers that look at the diets of past and present crocodylomorphs using patterns in teeth shape and enamel. It turns out, past relatives of crocodiles were likely a lot more experimental in the types of feeding strategies they implemented than we might expect. Meanwhile, Curt comes up with a great name for a Lamsdell lab bowling league, Amanda loves possums, and James has some very strong opinions about the “Cats” trailer.

Palaeo After Dark ·

2019/07/21

[TRIGGER WARNER: Some dead baby jokes because we were in a very weird mental place, and also way too much rambling conversations about Star Wars] The gang celebrates their cross continental trip to the 2019 North American Paleontology Convention by immediately getting on microphone the next day to talk about fossil Pterosaur eggs and what they can tell us about Pterosaur reproductive strategies. As expected, this may not have gone well. Witness the horror as barely conscious minds try and keep on

Podcast 165 - Sharks for St. Crispin's Day

Palaeo After Dark ·

2019/06/23

The gang have a “Shark Week” and discuss two papers about the ecology of modern tiger sharks. The first paper talks about a unique feeding strategy for some tiger sharks in which they can consume a fairly large amount of song birds. The second paper discusses how tiger shark populations are distributed around the islands of Hawaii, a place known for fairly high concentrations of tiger sharks. Meanwhile, James informs us of an important holiday, Curt imagines the ultimate battle of goose and shark,

Podcast 164 - Rails and Snails

Palaeo After Dark ·

2019/06/09

The gang talks about two papers that are interested in iterative evolution, the repeated evolution of the same or similar morphological characteristics within or among species. Specifically, they are focused on iterative evolution in species on islands. The first paper they discuss looks at how being flightless might have evolved multiple times on the same island within the same species of rails. The second paper looks at repeated changes in developmental timing associated with climatic changes on

Podcast 163 - Triassic Fish Questions

Palaeo After Dark ·

2019/05/26

The gang discusses two papers that look at the extinction and survivorship patterns of clades across the Triassic mass extinction event. Specifically, they look at changes in morphospace in ray-finned fishes as well as phylogenetic patterns of extinction in early archosaurs. Interestingly enough, both studies suggest very low ecological selection (at least in the characteristics we can study in the fossil record), but the archosaur study shows clear phylogenetic clustering of extinction. Meanwhile,

Podcast 162 - Turtle Power

Palaeo After Dark ·

2019/05/12

The gang discusses a few papers that look at the evolutionary history, biogeography, and life habit of Mesozoic turtles. Specifically, they look at a paper about a stem turtle with interesting information about the evolutionary history of turtle morphology, a paper on a special fossil of a marine turtle with exceptionally preserved eggs, and a paper that investigates the biogeographic history of turtles. Basically, its a whole lotta turtles! Meanwhile, James resurrects some old arguments, Curt

Podcast 161 - Whales Not Whales

Palaeo After Dark ·

2019/04/28

The gang discusses two papers that look at how various animals associated with whales have reacted to environmental shifts over the last several hundred thousand years. The first paper looks at polar bears and reviews data on the potential utility of whale carcasses on polar bear survival during warmer periods in recent Earth history. The second paper investigates how changes in the shell chemistry of barnacles attached to whales may preserve important information on whale migratory patterns

Podcast 160 - Weasel Time

Palaeo After Dark ·

2019/04/14

The gang finds two papers that discuss the ecology of fossil mustelids, the objectively best group of mammals. Both of these papers look at creative solutions to try and interpret past life habits for some very complex and debated fossil organisms. Meanwhile, James becomes passionate about food, Amanda wonders what sitcom the podcast must be, Curt discusses the true American Dream, and everyone is very sorry about how off track we get in this podcast.

Palaeo After Dark ·

2019/03/31

The gang discusses two papers about the Cretaceous mass extinction event (i.e. the time that the non-avian dinosaurs died). Specifically, they talk about the Deccan Traps, a widespread volcanic province that was active during the extinction event. The first paper studies the timing of the volcanic activity to determine if the onset of volcanism can be explained by the large bollide impact (Editors Note: Apologies to all igneous petrologists who will likely be yelling at our ignorance of hard rock

2019/03/17

The gang celebrates their 6th anniversary by taking some time to talk about two papers about early mammal ecology. The first paper looks at some unique traces left by Mesozoic mammals, while the second paper attempts to determine how early mammals might have chewed their food. Meanwhile, James has made friends with his new Eevee named DMX, Amanda finds the fuel to sustain herself, and Curt imagines some tactical mammal stealth action.

Podcast 156 - Never Underestimate the Little Snake

Palaeo After Dark ·

2019/02/17

The gang discuss two papers that look at the links between morphology and ecology. Specifically, they discuss a fossil marine reptile with a very unique looking skull that gives clues to a possible “platypus” like life-habit. However, they also discuss a modern ecological study of crustacean-eating snakes which shows that sometimes unique behaviors can greatly expand the potential prey species available to a predator. Meanwhile, James regales us with tales of an epic battle, Amanda is good at social

Podcast 155 - But What Would It Taste Like

Palaeo After Dark ·

2019/02/03

The gang discusses two papers that use fossil evidence to interpret physiology and functional morphology of extinct animals. First, we discuss a new study that suggests ichthyosaurs may have evolved blubber to help them regulate their temperatures. Second, we talk about a new study that uses robotic models to test how early tetrapods may have moved. Meanwhile, Amanda mixes caffeine and alcohol, Curt forgets Shane Black movies, and James tries to pull the ultimate mid episode twist. Up-Goer Five

2019/01/20

The gang gets together to record their first episode back from the holidays. And what better topic to discuss than hyoliths, those strange shelly Cambrian fossils. Specifically, the gang discusses two papers that look at new discoveries of the soft tissue and the hard shells of these hylothis to try and determine the evolutionary placement of hyoliths. Are hyoliths molluscs? Are hyoliths brachiopods? Are they somewhere in between? Meanwhile, Amanda hears some good news, Curt does his best hyolith

At the end of a long year, the gang takes a moment to reflect on the various strategies they use to try and keep themselves sane when things get stressful. So please join us as we discuss the joys of knitting, painting, and unconventional youtube video series in this special self care episode of Palaeo After Dark. Honestly though, it's a lot of knitting. Here’s to a safe and happy new year.

Podcast 152 - Community Reboot

Palaeo After Dark ·

2018/12/23

The gang looks over two older review papers that are interested in communities and trophic disruption. What is important in keeping communities together and how can stable systems become destabilized? They use these two review papers as a general jumping off point to talk about the difference between a species that is just non-native vs invasive, trophic collapse or cascades, and the importance of systems interactions in keeping communities at a stable equilibrium. Meanwhile, Amanda is always
