  2. Dentition - Wikipedia

    en.wikipedia.org/wiki/Dentition

    Since the origin of teeth some 450 mya, the vertebrate dentition has diversified within the reptiles, amphibians, and fish: however most of these groups continue to possess a long row of pointed or sharp-sided, undifferentiated teeth (homodont) that are completely replaceable. The mammalian pattern is significantly different.

  3. Heterodont - Wikipedia

    en.wikipedia.org/wiki/Heterodont

    In contrast, homodont or isodont dentition refers to a set of teeth that possess the same tooth morphology. In invertebrates, the term heterodont refers to a condition where teeth of differing sizes occur in the hinge plate, a part of the Bivalvia .

  4. Glyptosternon - Wikipedia

    en.wikipedia.org/wiki/Glyptosternon

    A recently published study reidentifies G. malaisei as a species of Glaridoglanis, on the basis of the spatulate, homodont dentition on both jaws and the premaxillary tooth patch not extending posterolaterally; and considers it to be a junior subjective synonym of Glaridoglanis andersonii.

    Another similar feature was the composition of the teeth, which contained mostly calcium phosphate which is needed for eating and drinking by aquatic animals, though, unlike modern day toothed whales, they had a heterodont (more than one tooth morphology) dentition as opposed to a homodont (one tooth morphology present) dentition.

    Although M. schmitti can reach between 300 mm to 810 mm in coastal areas with the highest recorded total length documented as 1100 mm. [4] Furthermore, M. schmitti has an inferior mouth with homodont dentition, which refers to the similarity in shape across all the teeth. [5]

  7. Cerrejonisuchus - Wikipedia

    en.wikipedia.org/wiki/Cerrejonisuchus

    The dentition of Cerrejonisuchus is generally homodont, although the third maxillary tooth is enlarged and the fourth is somewhat smaller than the rest. They are conical, labiolingually compressed, each having a relatively rounded apex.

  8. Armadillosuchus - Wikipedia

    en.wikipedia.org/wiki/Armadillosuchus

    Based on its dentition and size, it is believed that it was an omnivore, feeding on invertebrates, plants and possibly scavenging on occasion. Furthermore, its well developed forelimbs may have made the animal a capable burrower, which could have helped Armadillosuchus regulate its body temperature.

  9. Horse teeth - Wikipedia

    en.wikipedia.org/wiki/Horse_teeth

    Horse teeth refers to the dentition of equine species, including horses and donkeys. Equines are both heterodontous and diphyodontous , which means that they have teeth in more than one shape (there are up to five shapes of tooth in a horse's mouth), and have two successive sets of teeth, the deciduous ("baby teeth") and permanent sets.
