Meaning of trituberculy
trituberculy (n.)
A theory of the development of mammalian molar teeth. The primitive stage is that of simple cones, as in reptiles. The simple cone then developed a smaller cone in front and another behind. Next, a cingulum was developed, and the three cones became arranged in a triangle, the two smaller cusps having moved to the outer side in upper and to the inner in lower molars. This primitive triangle is called the trigon or trigonid and this stage the tritubercular or trigonodont. The trigon being a cutting apparatus, an extension of the posterior part of the crown was developed in lower molars for crushing, and a smaller corresponding part appeared in upper molars. Another large cone then arose, usually from the cingulum. In more complex forms, smaller intermediate cusps appeared.
trituberculy Sentence Examples
- The trituberculy of mammalian molars is a distinctive evolutionary characteristic that facilitates efficient grinding.
- Trituberculy in premolars provides an intermediate stage between the primitive tricuspid pattern and more specialized molar structures.
- Dental trituberculy is a key adaptation for the herbivorous diet of many ungulates, allowing them to grind plant material effectively.
- The trituberculate molars of primates exhibit a variation known as "anthropoid trituberculy," which is associated with a frugivorous diet.
- Trituberculy is an ancestral feature in mammals, with the earliest known examples appearing in the late Triassic period.
- The development of trituberculy facilitated the diversification of mammalian diets and the occupation of new ecological niches.
- Some rodents, such as squirrels, have simplified trituberculate molars that are adapted for gnawing.
- Carnivores typically have trituberculate molars that are modified for tearing and cutting flesh.
- The trituberculy of human molars provides a flat surface for mastication and helps prevent excessive wear and tear.
- Trituberculy in fossil teeth is a valuable indicator of the evolutionary history and dietary habits of extinct species.
