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?

In this episode, the gang has a conversation about the various factors affecting total global diversity and how these factors might affect patterns of radiations. Also, Amanda finds a new twitter handle, James drinks a few 11% alcohol beers,  Curt details Winnie the Poo's crack addiction, and the whole podcast is routinely interrupted by random people showing up during the recording. Also, congrats to Dr. James Lamsdell for successfully defending his thesis.

In this episode, the gang is all back in the same zip code and celebrate by having a long discussion on the origin and extinction of the large mammals from the Cenozoic known as the Megafauna. Somehow this gets.... weird. Meanwhile, James defends the Star Wars Empire, Curt argues why turtles should be ninjas instead of mere heroes, and Amanda confuses Michael Bay with Roland Emmerich. Also, congrats to Dr. Amanda Falk for defending her thesis.

With thesis defenses on the horizon, the group looks to a comforting and familiar topic to escape their morose nerves; mass extinctions. Specifically, they discuss two papers about patterns of survivorship across mass extinction events and use this as a springboard to talking about general macroevolutionary patterns. Also, James fires Curt, Amanda fires James, and Curt decides to host his own private podcast in the middle of the real podcast with special guest Amanda. SPOILERS for House of Cards in the first 30 seconds of the podcast.

In this episode, the gang “gives the people what they want” by talking about two papers that look at a giant theropod dinosaur from the Iberian Peninsula. Also, Curt discusses alternate Star Wars history, James requests that everything be cut, and Amanda goes “full dragon”.

In celebration of the podcast’s one year anniversary, the gang decides to discuss two papers about live birth in the fossil record. At least.... that was the plan.... however the second paper proves to be far more problematic than the gang had bargained for. What started off as a simple, breezy pun takes a... darker turn. Isn’t that how all birthdays go, though?

 

Meanwhile, James discusses the importance of proper breeding in selecting your animal metaphors, Curt tells the apocryphal story of the podcast’s “history”, and the whole gang talks at length about the secret xenomorph invasion during the Triassic. Also, the gang gets a whole new set of microphones and everyone is super excited about them, especially James’ heater which occasionally stops by to say hello.
