Bulbasaurus

Who’s that synapsid?

It’s Bulbasaurus phylloxyron!

This creature was a member of the dicynodonts, a group of herbivorous mammal-relatives with beaks and protruding tusks. Its fossils are known from the Late Permian of South Africa, about 259-254 million years ago, and it would have been roughly the size of a cat, around 60cm long (2′).

It wasn’t officially named after the pokémon character Bulbasaur, but instead in reference to the bulbous bosses on its snout. But combined with how the species name “phylloxyron” means “leaf razor”, it doesn’t seem to entirely be a coincidence.

Geikia

Geikia elginensis, a dicynodont synapsid from the Late Permian of Scotland (~254-252 mya). Known only from a single skull discovered in the 1890s, it would have measured around 50cm long and was closely related to South African forms like Bulbasaurus.

It had an unusually shortened snout and forward-facing eyes – sort of like a pug with a beak – and a pair of protruding nasal bosses on its snout. It was probably a selective browser, biting off small pieces of vegetation at a time, and its large eyes and stereoscopic vision suggest it may have been nocturnal.
