Guest Interview

Tyler Greenfield is a paleontologist and cryptozoologist whose blog, Incertae Sedis reveals the truth behind some cryptozoological stories and paleontological mistakes. Since his appearance on episode 10, Tyler has finished his bachelor’s, written a good few papers, appeared on other podcasts (none as good as his debut of course) and is almost done with his masters and is about to start his PhD.

The BBC posted a clip of Spinosaurus hunting Onchopristis from "Walking with Dinosaurs" on YouTube, which anyone should be able to watch. The entire episode should be available for free on the BBC website for anyone in the UK and on the PBS website for anyone in the USA.
