Comment on Tylosaurus pembinensis by DrScottHartman

I can definitely see why good quality mosasaur skeletals are so rare. At least for Mosasaurus anyway. It barely has anything substantial pictured that's available online, despite having so much written about a lot of very specific details from supposedly fairly complete specimens.

That and I found the vertebrae are such a grind to draw. 

If you ever do end up looking into Mosasaurus, I really hope it goes a lot more smoothly for you than it did for me, lol.
