Palaeoscincus

Palaeoscincus (meaning "ancient skink" in Greek) is a genus of ankylosaurian dinosaur based on teeth discovered in Montana. Like several other dinosaur genera named by Joseph Leidy ("Deinodon", "Thespesius", and "Trachodon"), it is an historically important genus with a convoluted taxonomy that has been all but abandoned by modern dinosaur paleontologists. Because of its wide use in the early 20th century, "Palaeoscincus" is often shown with the armor of "Edmontonia" and the tail club of an ankylosaurid.
