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).

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.

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.

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.

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”.

In this week's episode we discuss a paper about using paleobotany to reconstruct paleoclimate, and then spin this discussion into a longer talk about niche conservatism. Meanwhile, Curt violates Godwin's Law by comparing something that is merely horribly unethical with something that is an absolute evil, James gives the Internet and by extension the world an ultimatum, and Amanda confesses to serial herbicide. We also completely mess up our discussion of what stomatal density is used as a proxy for (hint: it’s actually CO2 concentration.... but we apparently forgot that).

What started as a simple conversation about the Island Rule and small sauropods quickly became a fight for survival as the internet itself rose up to destroy the group. Separated and alone, silenced and cut off by the terrors of this monstrous world wide web, the gang fights to salvage a podcast from the terrible dreck that is, "Horror on Podcast Island 3".

THRILL as Curt creates the perfect designer pet. SCREAM when James details his bizarre dreams. And NO ONE WILL BE ADMITTED TO THE THEATER when Amanda destroys all evidence of her involvement with the show.

In this episode, the gang repeatedly violates Godwin's Law by comparing everything to the Nazis/Hitler. And they also discuss two papers which deal with understanding the complicated originations of evolutionary groups. Meanwhile, James discusses his future career options, Amanda willfully mispronounces the plural of LEGO, and Curt explains why he is never funny. Follow along at home kids and see if you can count all of the Nazi jokes (the true answer might surprise you).

In this episode, the gang gets vitriolic about people getting vitriolic as they discuss the unexpected drama that ensued after a seemingly benign paper on the phylogenetic position of fossil remoras was published. Furthermore, after angrily pleading for everyone to calm the hell down, Curt then proceeds to spread the hate around. Also, Amanda enjoys a delicious non-kosher ham and James extols the virtues of vegetarianism while eating ham.

Also ham.

In this very special episode of Palaeo After Dark, the gang wrestles with the controversial topic of fossil commercialization. Furthermore, tragedy strikes when James discusses the butt-hurt level of animals, Curt needlessly segues into Wounded Knee, and Amanda’s injured back is actively ignored. Will the gang be able to survive this meandering discussion, or will their friendships be forever torn apart?
