Podcast 100 - Too Much to Bear

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 cigarette between her fingers, her gaze furtively snapping back and forth between the barely illuminated run down two story building, the "Motel Manna", and the vast empty night. The unexpected flash of a pair of headlights from an all too familiar Dodge catches her gaze and for a second she freezes in place and hopes it's all a dream. The car stops and she knows she's been seen. "Fuck it" she says to herself, cigarette now firmly clenched so tightly in her jaw it would take a crowbar to pry it out. Summer nights like these can just be too much for one person to bare.

"Too Much to Bear" is a story of murder, betrayal, and bear smuggling.

Podcast 98 - When the Mammal Extinctions Are

<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 Footballs, and Amanda really would like to know WHEN we're going to start discussing the papers.

Podcast 97 - Big Heads

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.

Podcast 86 - Echolocation in the Fossil Record

The gang discusses two papers that use functional morphology to determine when echolocation evolved in two groups of mammals, whales and bats. Also, Curt rattles off a wikipedia page on hamburgers, James fights against physics, and Amanda would rather talk about how terrifying Basilosaurus is. Also, to cut this off at the pass, a correction. Bats are the "SECOND" most diverse mammal group and rodents are the most diverse.
