The Poundersaurolophus is a species of Dinotrux, combining aspects from a Pile driver and a Parasaurolophus. They are often referred to simply as Pounders, with one serving as one of the main antagonists of the series beginning in season three.
Pounders possess pile drivers for faces and have clawed tails that can grip objects or other Dinotrux. Though they are not the largest variety of Trux, their raw power enables them to take on and drive away Tyrannosaurus Trux and Craneosaurs. The only specimens seen in the series have not spoken, though they have demonstrated intelligence and the ability to understand other Trux. Pounders operate by using their raw power to smash structures, rocks, and other Trux in order to mark their territory and drive out unwanted others; this appears to be done mainly for ore.
