Donald M. Henderson is a Canadian paleontologist working in Alberta. He specializes in bite strength comparisons in ceratopsians, dinosaur buoyancy, and studying dinosaur locomotion.
Donald got interested in paleontology through the art of dinosaurs. He obtained his Bachelor's from the University of Toronto in 1992, and finished his PhD at the University of Bristol in 1999. He is currently the Curator of Dinosaurs at the Royal Tyrrell Museum in Drumheller, Alberta.
Donald is a proponent of pushing the importance of art and dinosaur illustrations in the science of paleontology. In 2015, he published a paper based on a painting by Robert Nicolls called "Double Death". in the painting, two Carcharodontosaurus saharicus have a juvenile Limaysaurus tessonei suspended between them while fighting over it, one holding the tail and one holding the neck. In his paper, Donald proved that this painting was factually possible based on estimated lifting strengths of the Carcharodontosaurus necks.
Donald has described, or helped describe, two new species of dinosaur.
