For years, they've been spraining ankles and shearing teeth in an effort to best each other at basketball, football and hockey.

The Jarada had a narrow pointed snout and a hooked jaw with sharp, shearing teeth in the front.

Like other ceratopsians, Graciliceratops would have been an herbivore, using its powerful beak and shearing teeth to process tough plant matter.

He found that these milk teeth are used for eating solid food as soon as the principal shearing teeth are in place.

The dog linage began 37 million years ago in North America in predators that had distinctive pairs of shearing teeth and ran down prey.

It also lacks the shearing teeth common to most carnivores; the crushing molars of a bear are believed to be an adaptation for a plant diet.

The shearing teeth and strong masseters suggest that it was more specialised to grind and crush flesh and bone than other bat species.

Born with shearing teeth and an insatiable appetite for flesh, he seemingly fulfils the pact when he destroys the last known batch of Saurian eggs.

Unlike most modern carnivorans, in which the carnassials are the sole shearing teeth, other creodont molars have a subordinate shearing functions.

However, instead of grinding or shearing teeth to break up its prey, the creature had a long, retractile proboscis with a serrated edge for piercing its victim's flesh.

Rather than the shearing teeth typical of most carnivores, sea otters have bunodont molars adapted for crushing hard-shelled invertebrate prey (Riedman and Estes 1990).

They have sharp-edged, shearing teeth, and a movable joint between the skull and jaw suspension that allows the lower jaw to move back and forth in a sawing motion.

In the borhyaenids the upper carnassials appear to have been rotated medially around the anteriorposterior axis of the tooth row in order to maintain tight occlusional contact between the upper and lower shearing teeth.

In the lower jaw, behind the canine, there is first a minute peglike tooth, second a two-rooted tooth similar in general outline to a permanent third premolar, and finally a shearing tooth corresponding in function to m1 of the permanent dentition.

These shearing teeth are used for almost two months before being replaced by the permanent teeth and it is, therefore, evident that natural selection could operate to fully as great a degree in determining the form of the deciduous teeth as it may with the permanent teeth.

All known species were quadrupedal herbivores from the Upper Cretaceous, mainly of Western North America (though Sinoceratops is known from Asia) and are characterized by beaks, rows of shearing teeth in the back of the jaw, and elaborate horns and frills.
