Fabiany Herrera is a paleobotanist specializing on a diverse array of time periods and paleofloras, including the Mazon Creek Flora from the Carboniferous when Lycopods were friggin' trees, as well as the utterly bizarre Jurassic and early Cretaceous Bennettitales & Corystospermaceae from the excellently preserved Mesozoic lignite of Mongolia.

Many of the plants we talk about in this episode HAVE NO LIVING OR EXTANT RELATIVES - they represent fantastical lineages of plants whose base branches that simply got clipped off the tree of life either during mass extinctions events or gradually during climatic changes. Umaltolepis - a ginkgo relative - is an exception to this, but still an equally bizarre plant.

This was a really fun conversation and it could've gone on much longer but we ran outta time. Hope you enjoy.
