Closeup of M. hoffmannii teeth, with a replacement tooth developing inside the root of the lower right tooth. The features of teeth in Mosasaurus vary across species, but unifying characteristics include a design specialized for cutting prey, highly prismatic surfaces (enamel circumference shaped by flat sides called prisms), and two opposite ...
Mosasaur teeth are of rather uniform morphology (with a few exceptions, such as in Globidens) with a pointed and curved tooth crown that sits on a pedicel composed of bone. [7] The enamel surface is smooth and the crown is subdivided into a lingual and labial surface while the outer surface of the crown is made of enamel and the inner layer is ...
Instead, they primarily relied on stratigraphic associations and Cuvier's 1808 research on the holotype skull. Thus, in-depth research on the placement of Mosasaurus was not undertaken until the discovery of more complete mosasaur fossils during the late 19th century, which reignited research on the placement of mosasaurs among squamates.

A side-by-side comparison of a typical "crushing" mosasaur tooth (left, Igdamanosaurus) and a typical "cutting" mosasaur tooth (right, Mosasaurus). Teeth of Prognathodon seem to contain characteristics of both. It is worth noting that P. overtoni displays heterodonty similar to other mosasaurines, such as Globidens and Carinodens. For instance ...
Tooth remineralization is the natural repair process for non-cavitated tooth lesions, [1] [2] in which calcium, phosphate and sometimes fluoride ions are deposited into crystal voids in demineralised enamel. Remineralization can contribute towards restoring strength and function within tooth structure.
Globidens ("Globe teeth") is an extinct genus of mosasaurid oceanic lizard classified as part of the Globidensini tribe in the Mosasaurinae subfamily. Globidens belongs to the family Mosasauridae, which consists of several genera of predatory marine lizards of various sizes that were prevalent during the Late Cretaceous.
These crowns are also flared at their bases and have smooth enamel surfaces. [1] The dental bones have fifteen teeth on each side. The pattern of heterodonty in the lower dentition mirrors that of the premaxilla and maxillae. The first five teeth are straight and conical and each has only one dentate tooth and an anterior keel.
Russell (1967, pp. 123–124) [6] defined the Mosasaurinae as differing from all other mosasaurs as follows: "Small rostrum present or absent anterior to premaxillary teeth. Fourteen or more teeth present in dentary and maxilla. Cranial nerves X, XI, and XII leave lateral wall of opisthotic through two foramina.
