I'm curious about the first "beaker" and that last one was inspired by Indricotherium, wasn't it? <u<
The "beaker" was based on a sketch I made, one of several, of various head shapes for a predatory thornback. I couldn't think of which one could give rise to a predator, then I looked at the wiki, and noticed what had moved into the Fermi coastline... the Jaydohve. And since Jaydohves need to roost on dry land from time to time, and the only dry land nearby was Fermi island... well let's just say I made a few modifications to the design and that the rest was history.
As for the last one, that was entirely coincidental. I drew the head first, then based the body on the Voracious Anklebiter Thornback, and created a flora that would experience gigantism in order to provide a food source.
