- n. Any of various very large extinct aquatic lizards of the genus Mosasaurus, having modified limbs that served as paddles for swimming. These lizards, thought to have been viviparous and carnivorous, may be early ancestors of the modern monitor lizard.

- n. A general name for the large, extinct marine reptiles of the family Mosasauridæ, including the well-known genera Mosasaurus, Tylosaurus, Clidastes, etc. They had long, pointed heads, rather long bodies, a compressed tail, and limbs modified into short, flattened paddles. They abounded in the Cretaceous period and their remains are particularly abundant in the chalk of Kansas.
The word mosasaur comes from the Meuse river in France.
Pro from Dover: Cuvier was in correspondence with Camper and eventually came around to his conclusion that the mosasaur was a lizard.
Another one of his discoveries, considered the most complete fossil ever found of an extinct marine lizard called a mosasaur, is displayed next to the pregnant plesiosaur.
The mosasaur is a large marine lizard that lived around the end of the Cretaceous period, about 85 million to 65 million years ago, and inhabited the shallow seas that once covered much of Saskatchewan.
A mosasaur seemed the obvious choice, given your half-dozen publications on them!
Well, I've done it once myself, describing a new mosasaur genus and species, Selmasaurus russelli.
And as if that still wasn't cool enough, it was inscribed to me, with a mosasaur illustration!
I should make a post about all the not-so-good mosasaur figurines that have come and gone over the years.
Finally, someone has made an accurate mosasaur figure!
This is interesting for mosasaur specialists of course, but it also allows me an opportunity to talk about two often-misunderstood terms in evolution - “missing link” and “primitive”.
