[PAR] [TLE] Palaeoscincus [SEP] Palaeoscincus (meaning "ancient skink" from the Greek παλαιός and σκίγγος) is a dubious genus of ankylosaurian dinosaur based on teeth from the mid-late Campanian-age Upper Cretaceous Judith River Formation of 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, it was somewhat well-known to the general public, often through illustrations of an animal with the armor of "Edmontonia" and the tail club of an ankylosaurid. [PAR] [TLE] Judith River Formation [SEP] The Judith River Formation is a fossil-bearing geologic formation in Montana, and is part of the Judith River Group.  It dates to the upper Cretaceous, between 80 and 75 million years ago, corresponding to the "Judithian" land vertebrate age.  It was laid down during the same time period as portions of the Two Medicine Formation of Montana and the Oldman Formation of Alberta.
