Podcast 48 - BearShark

/

The gang gins up a flimsy excuse to talk about short-faced bears and megalodon. Also, Amanda researches topics for future podcasts on air, Curt becomes transfixed by Google image searches, and James's mind is broken by the thought of Mr. T.

Podcast 47 - A Merry Little Maiming; Pathology in the Fossil Record

/

In this episode, the gang looks at a few cases of fossil pathologies in arthropods, birds, and amphibians and discusses the interesting broader evolutionary ramifications of these studies. Meanwhile, Amanda wrangles cats, and Curt confuses everyone by consistently assigning taxa to the wrong groups (for example: loriciferans are not priapulids, even though they are closely related). Oh... and  James leads a legitimate discussion on science ethics.

Podcast 46 - Better Circles; A Rambling Conversation About Higher Taxa

/

After spending 2 hours fighting the internet (drinking the whole time), the gang finally starts recording a bit tipsy and ends the evening fairly wasted. And like an e-mail sent after a long night out at the bars, they record a podcast on properties of higher taxa that they immediately regret in the sobering light of day.

Podcast 45 - Ethics in Kangaroo Journalism

/

The gang stumbles their way through several papers about kangaroos, particularly focusing on a meat eating rat kangaroo. Also, stressed and annoyed at the current internet climate, James and Curt spend most of the podcast relentlessly mocking GamerGate while Amanda decides to ignore them and play with the cat. Also.... texting.

Podcast 43 - Nontroversy; The Tale of the Dog-Paddling Spinosaurus

/

The gang discusses the new Spinosaurus material while also trying to completely alienate their audience, starting at jingoistic humor and ending with mass suicide jokes. Meanwhile, Amanda discusses her misgivings about musicals, James compares the other podcast hosts to Peanuts characters, and Curt struggles to understand a perplexing metaphor.

Podcast 42 - Terror Birds and Captain Scarlett

/

In this episode, the gang concludes their marathon of prerecorded episodes with two papers about the biomechanics of the Terror Birds. We also talk about chukars for pretty much no reason. Also, Curt freaks out about birds, James starts a rumor about Aristotle, and Amanda is assaulted by her cat.

Podcast 41 - Hallucigenia; Eating Planets and Crapping Rainbows

/

In this episode of Palaeo After Dark, the gang discusses the complicated history of Hallucigenia, and somehow gets completely derailed into rambling conversations about Star Trek 5, proper pronunciation, Gould’s “Wonderful Life”, microwave ovens, the effects of aging on your storytelling abilities, natural kinds versus individuals, puppy petting, poor puns, minions, food, Hell and Michael Bolton, LSD, oracles, stilt walkers, emus, otaku cat people, evolutionary convergence, My Little Pony, tripe, confusing a camera with a mouth, rubber bands, contingency, the importance of bricks, improper ways to train your cat/James, choking hazard candies, milk allergies, sharing, and historically important beers. Also, Amanda shares her reconstruction of Hallucigenia in its natural habitat (why it has a shapely pair of human legs, no one can say). If you want to get the point where we actually start talking about science, skip to 19:39 (it’s one of those podcasts).

Podcast 40 - Treading Water; Let's Talk About Hippos

/

In this episode, the gang spirals into insanity while discussing a strange paper about hippo biogeography. Also, James discusses childhood cartoon trauma, Amanda graduates from beer to vodka, and Curt lowers the bar.

Podcast 39 - Fractal Fronds; Ediacaran Ecology

/

In this episode, the gang discusses two papers that look at the ecology of the early life forms of the Ediacaran period. Also, James discusses the American dream, Curt details the secrets of the podcast's "success", and Amanda is nearly murdered by her cat.

Podcast 38 - Podcast Team VS The League of Sinister Papers

/

This week, instead of picking papers with a similar theme the gang decided to talk about the craziest papers they could find. The end result: yetis and airplanes... Maybe this was a mistake.

Meanwhile, James describes his theory of automobile evolution, Amanda discusses swimming polar bears, and Curt describes the life and times of the podcast gang in Tomodachi Life.

Podcast 37 - Derp Birds

/

In this episode of Palaeo After Dark, the gang discusses two papers that use morphometric analysis to test how strongly ecology imprints on evolution, which culminates in Curt drunkenly stumbling his way through hierarchy theory. Also, James and Curt talk about the wonder that is Machete Kills, and Amanda wins an argument only using the word “meh”.
