  2. Mosasaurus - Wikipedia

    en.wikipedia.org/wiki/Mosasaurus

    In each jaw row, from front to back, Mosasaurus had: two premaxillary teeth, twelve to sixteen maxillary teeth, and eight to sixteen pterygoid teeth on the upper jaw and fourteen to seventeen dentary teeth on the lower jaw. The teeth were largely consistent in size and shape with only minor differences throughout the jaws except for the smaller ...

  3. Mosasaur - Wikipedia

    en.wikipedia.org/wiki/Mosasaur

    Mosasaurs possessed a thecodont dentiton, meaning that the roots were cemented deeply into the jaw bone. Mosasaurs did not use permanent teeth but instead constantly shed them. 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.

  4. Globidensini - Wikipedia

    en.wikipedia.org/wiki/Globidensini

    Both the genera Globidens and Prognathodon (sometimes classified as a globidensin, though most often not) have adaptations to a powerful jaw musculature. The ratio between the length of the supratemporal fenestra and the total length of the skull has previously been used as an improvised measurement for mosasaur bite force, and is quite high in these genera (0.27 in Globidens dakotensis and 0. ...

  5. Thalassotitan - Wikipedia

    en.wikipedia.org/wiki/Thalassotitan

    Like all mosasaurs, Thalassotitan had four types of teeth, corresponding to the jaw bones they are located on. On the upper jaw were the premaxillary teeth, maxillary teeth, and pterygoid teeth (located separate from the main jawline near the rear of the skull); while on the lower jaw only the dentary teeth were present.

  6. Carinodens - Wikipedia

    en.wikipedia.org/wiki/Carinodens

    Carinodens is an extinct genus of Cretaceous marine lizard belonging to the mosasaur family. "Carinodens" means "keel teeth" and was named in 1969 as a replacement name for Compressidens, "compressed teeth", which was already in use for a gadilidan scaphopod mollusk.

  7. Prognathodon - Wikipedia

    en.wikipedia.org/wiki/Prognathodon

    As with most mosasaurs, the teeth of these specimens are carinate, with the carinae aligned roughly parallel to the jaw. On unworn teeth, the apex is acute but blunt, and has fine, wavy, anastomosing ridges for as much as 25% of the crown height. Such ornamentation could potentially strengthen the teeth.

    An intact prehistoric mastodon jaw was discovered in the backyard of a Hudson Valley house after the homeowner initially saw a pair of teeth poking up by a plant, according to state officials.

  9. Mosasaurini - Wikipedia

    en.wikipedia.org/wiki/Mosasaurini

    Bell proposed that the Mosasaurini should be abandoned and that all members of the tribe should be incorporated into the Plotosaurini. While other scientists agree that a tribe containing Mosasaurus should be monophyletic, they argue that Mosasaurini should be the valid tribe. For example, in a 2012 study, Aaron LeBlanc, Caldwell, and Bardet ...
