From the about page:
Mythic Articulations was created in late 2013 with one goal in mind ― to create what nature won't. More specifically, to create the skeletons and skulls of mythical creatures and cryptids. We offer a growing variety of replica osteological specimens of animals that you just can't get anywhere else, because they don't exist (or haven't been proven to exist). Be it the elusive Bare-Fronted Hoodwink, the mighty Wolpertinger, or something else that you might have actually heard of, we'll do our best to make it real. We use state of the art 3D Printing techniques to create each replica.Check out his website, Mythic Articulations, for his designs, which are 3D printed to order and mailed to you via Shapeways (where I found his work) or his Etsy shop. He also does prints and some poseable skeletons.
