Comparison of Some Mosasaurs

Here we compare the medium-sized Platecarpus tympanicus (a rather generalized species), the also-medium-sized Globidens dakotensis (with robust jaws), and the small Carinodens belgicus (with almost saw-like teeth). These animals are NOT to scale. The latter two belong to a clade called Globidensini, which represent one of the more unusual, though less well-preserved, groups of mosasaurs out there, which develop deeper jaws and broader teeth than the rest.
