 Due to force exerted by the lower jaw when biting against the upper jaw would decrease with the distance from the joint, the anterior teeth would have been ineffectual for biting and crushing.During jaw adduction, however, the speed of the anterior teeth could allow "Pluridens" to swiftly catch and penetrate small soft prey and a large number of teeth would ensure that it did not loose hold of the prey.The tooth crowns are broad and short which indicates that they were used for crushing, perhaps of thinshelled invertebrates.
