Episode 204 - The Messinian Salinity Crisis
Around six million years ago, the Mediterranean Sea dried up, wreaking havoc with local marine life and leaving a dramatic legacy in the geologic record in the form of massive salt deposits. This episode, we’ll explore the evidence for this event, why it happened, how it ended, and the impact it left in the fossil record.
In the news: marine crocs, giant cicadas, giant tadpoles, and drowning bats.

Cute-E - Jackalopes
Welcome … to Cute-E!
Every October during Spook-E, we have fun speculatively evolving monsters from myths and stories, but we leave out the cuddlier side of fiction. In Cute-E, we’re choosing kinder creatures and discussing how they – or something like them - could evolve here on Earth, pulling inspiration from real-world species across our planet’s history. This year’s theme is Tiny Monsters.
This episode, we look at a local legend. How might real-world evolution result in elusive and mysterious rabbits with antlers? Our creatures to create this time: Jackalopes.

Episode 202 - Fungi and Animals
It’s the final part of our fungal trilogy!
Fungi and animals interact in a wide variety of ways, from parasitism to partnership to predation. This episode, we explore how fungi and animals have evolved alongside each other and the adaptations they have developed to take advantage of each other, and we’ll examine how far back we can find these fungus-animal interactions in the fossil record.
In the news: pterosaur feet, sauropod tails, a Cretaceous crater, and fossil fireflies.
