The number of prisms in Mosasaurus teeth can slightly vary between tooth types and general patterns differ between species [g] —M. hoffmannii had two to three prisms on the labial side (the side facing lips) and no prisms on the lingual side (the side facing the tongue), M. missouriensis had four to six labial prisms and eight lingual prisms ...
Replacement teeth developed within a pit inside the roots of the original tooth called the resorption pit. This is done through a distinctively unique eight-stage process. The first stage was characterized by the mineralization of a small tooth crown developed elsewhere that descended into the resorption pit by the second stage.
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 ...
An 1854 depiction of Mosasaurus in Crystal Palace Park. One of the earliest paleoart depictions of Mosasaurus is a life-size concrete sculpture constructed by natural history sculptor Benjamin Waterhouse Hawkins between 1852 and 1854 as part of the collection of sculptures of prehistoric animals on display at the Crystal Palace Park in London.
The crown length is greater than the crown width in front of the tenth maxillary tooth. The maxilla is long and the frontal is narrow. The frontal bone slightly enters the orbits dorsally. [3] G. dakotaensis Russell, 1975 - The height of the tooth crown is less than the greatest tooth crown diameter behind the fourth maxillary tooth. The crown ...
De Saint-Fond's romantic but inaccurate presentation of the discovery of Mosasaurus showing Hoffmann on the left. Johann Leonard Hoffmann (1710–1782) was a Maastricht army surgeon and amateur geologist who collected fossils from the local Mount Saint Peter .
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.

The teeth have a slight posterior and medial recurvature and are noted for having smooth surfaces (which is different from other species of Prognathodon) except for minor wrinkles at the tips of the tooth crowns. The roots of the teeth are quite large at about 1.5 times the size of the tooth crowns and are barrel-shaped.
