Description
A small, large-eyed mosasaur from the Late Cretaceous of the northern continents, its name sounds like someone wanted to outdo Platecarpus. Proportions here are almost entirely based on scale bars, so even though those were for the most part consistent, they may not be the most reliable.References:

Is the fish-like tail, with the longer lobe on the bottom - as opposed to the more traditional eel-like tail - preserved in the fossil record? I'm no mosasaur expert, but I've noticed a lot of modern reconstructions are portraying the fish-version.

As far as I know, it's not preserved for many species, but in some specimens (Prognathodon is one I recall) the soft tissue outline shows the fish-like tail, and in others like Tylosaurus and Platecarpus, you can spot where the tail would have to be broken in order to support the flat eel tail. Since no soft tissue impressions have turned up with an eel-shaped one, most people have been bracketing the fish shape to all derived mosasaurs.

It's a composite of marshi specimens made by Lingham-Soliar; he may have used primaevus as a guide, but I'm not sure it was possible then.

Why this one has a very fat scale bar, or should I say scale cube?

Looked better for the floating mosasaur.
