Sell them. I would buy one.
Very cool...i'd buy them too. In fact, you could be on to a winner here...making accurate ,life sized models of the species we're all crazy about....
Also, make a diploclaus?...spelling?
Pretty good job, nice craftsmanship, indeed! Quality there! i may have to bother you when i have $$$$ to spend! You do this things for museum, you should, if not, you can make a few bucks selling them to geeks like us.
Aphaneramma would be an interesting one or a Gerrothorax those kinda look silly. But i prefer Acanthostega and Ichthyostega and those lovely early tetrapods. Good luck if you ever do a Tiktaalik!
