Palaeo After Dark

The gang discusses three papers that detail some truly unique examples of morphological convergence; from brachiopods that look like corals to bovids with dinosaurian nasal crests. Also, James designs some conspicuous Mario levels,  Amanda wins an argument that "never happened", Curt is excluded from a business venture, and everything comes back to Zardoz.

In this episode, we discuss the complex relationship between fungi and earth systems processes through time, focusing on the potential role of fungi in facilitating early terrestrialization and the proposed hypothesis that fungi may (or may not) have been indirectly responsible for the Carboniferous coal swamps. Also, Amanda aggressively segues, Curt derails the conversation into navel gazing about the nature of scientific fields, and James goes on a fascinating journey from Angry to Annoyed finally ending up at Resentfully Happy.
