Description
Platynota>Mosasauroidea>Mosasauridae>Tylosaurinae>Tylosaurus>T.proriger
Cope, 1869
Time: Santonian-Middle Campanian (86.5-75 million years ago)
Length: Up to 12.75 meters, based on the ''Bunker'' specimen (1.8m skull)
Weight: Up to 6.1 tonnes, based on a GDI scaled to the length of the ''Bunker'' specimen.
Habitat: Seas of the Western Interior Seaway, Kansas, Alabama, Nebraska and much of the central U.S, North America. The genus is also known from Europe and possibly Alaska, in the Maastrichtian. The preferred environment of Tylosaurus seems to have varied depending on the region in which they lived, with individuals found in Alabama living preferably in shallow and nearshore waters, and favoring deep water far from shore in the western U.S.
Ecology and hunting habits: Large aquatic apex predator. Tylosaurus may have used its long, cylindrical snout to ram against prey or in intraspecific combat.
Diet: Contemporary bony fish, sharks, smaller mosasaurs, elasmosaurid plesiosaurs, and flightless diving birds such as Hesperornis. In one occasion, a Tylosaurus is known to have scavenged the corpse of a hadrosaur that was carried off to sea.
Competition: Fellow Tylosaurus, seeing as mosasaurs, like their modern relatives, were most likely cannibalistic.

I never thought I would have so little to say about this thing. (kinda) Requested by .

Update 07/08/17:
-Lineart completely remade.
-Replaced human scale figure
-Updated common name (just added Sea because why not)
-More accurate size estimate, now along the centra as is the norm, instead of in a straight line.
-Removed ''average adult'' estimates, they're dumb.
-Minor text corrections.
