Palaeo After Dark

The gang talks about two papers that detail the ecology and evolution of some early fishy vertebrates. Can we tell what early coelacanth fish might have eaten? What evolutionary changes occurred when early tetrapods started making their way onto land? Is there an evolutionary trend towards kawaii? All this and less will be discussed.   Oh, and James has made some interesting discoveries about The...

Musical track, "Sail the Canals" from Mario Part...

The gang discusses how exceptional fossil preservation can change our understanding of ancient life, focusing specifically on two new studies that offer insight into trilobite reproduction and hyolith evolution respectively. And when faced with the challenge of describing the indescribable weirdness of hyoliths, the gang falls back on their old mainstay of saying "It's weird" and derailing the con...

Curt thought that a simple podcast about preserving color patterns in feathers would be fun. Little did he know, this decision would end up pushing the group's friendships to the limit. Will the podcast survive? Will there be an episode 103? Find out in two weeks.

The gang celebrates their 100th episode by taking a break and playing Fiasco, a crime/noir storytelling game by Bully Pit Games. A fluorescent motel sign illuminates the inky blackness, its crackling electric hum merging perfectly with the clicking of the cicadas in the humid summer night. A solitary figure stands nearby, barely visible in the garish green and orange glow. She nervously rolls a ci...

In this episode, the gang discusses two papers that look at the ecological and evolutionary impacts of animal camouflage.

Scott Mills, and J. Joshua Nowak. "High fitness costs of climate change‐induced camouflage misma...

< Editor's Note : Skip to 13 minutes in if you only want to get to the science. I didn't have the heart to cut the intro down> In this episode, we eventually get to discussing patterns of extinction selectivity in mammals during two major extinctions (the end Cretaceous and the modern biodiversity crisis). Also, James discusses delicious ways to end the world, Curt details the Lord of the Football...

The gang discusses two papers about archosaur heads, one of which is actually about archosaurs with big heads. Also, Amanda's cat gets revenge for the podcast thumbnail, James wants to be a super villain, Curt decides to drink, and we all design better dinosaurs. Also, this cockatoo gif is a thing that should be known and celebrated. http://i.imgur.com/mZEnTJc.mp4 Midi music from freemidi.org Refe...

The gang discuss two interesting fossil localities that allow us to see snapshots of ancient ecosystems. Meanwhile, Curt describes an alternative Madden series, Amanda is given questionable life advice, and James comes up with a "story" for our fossils. References:  Smith, Krister T., and Agustín Scanferla. "Fossil snake preserving three trophic levels and evidence for an ontogenetic dietary shift...

The gang discusses two papers that deal with the age of animals, one fossil paper looking at tyranosaurids and one modern example looking at Greenland sharks. Meanwhile, Amanda has unique pronunciations, James invents a series of "better" movies, and Curt gets contemplative when left alone.  References:  Nielsen, Julius, et al. "Eye lens radiocarbon reveals centuries of longevity in the Greenland...

It's that time of year again as James and Curt travel to Denver and see the cool, new, interesting paleo research that's going on at the Geological Society of America Meeting 2016. This year they're joined by friend of the podcast Brendan Anderson, as well as ammonoid worker Carine Kline, evolutionary biology April Wright, and a very exuberant and somewhat inebriated David Bapst. Day 1 with James...

In this episode, the gang discusses two studies that look at the extent to which the ecological preferences of an organism are linked to that organism's morphology. Meanwhile, Curt has an existential crisis, Amanda stops caring to the extreme, and James desperately asks for another take. References: Smithson, Timothy R., Kelly R. Richards, and Jennifer A. Clack. "Lungfish diversity in Romer's Gap:...
