Palaeoscincus
''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. Reassigned species Seven species have been referred to this genus over the years, six of which have since been reassigned to other genera: *''Palaeoscincus africanus'', named by Robert Broom in 1910/1912, a partial jaw from the Tithonian-Valanginian-age Upper Jurassic-Lower Cretaceous Kirkwood Form ...

Edmontonia
''Edmontonia'' is a genus of panoplosaurin nodosaurid dinosaur from the Late Cretaceous Period. It is part of the Nodosauridae, a family within Ankylosauria. It is named after the Edmonton Formation (now the Horseshoe Canyon Formation in Canada), the unit of rock where it was found. Description Size and general build ''Edmontonia'' was bulky, broad and tank-like. Its length has been estimated at about 6.6 m (22 ft). In 2010, Gregory S. Paul considered both main ''Edmontonia'' species, ''E. longiceps'' and ''E. rugosidens'', to be equally long at six metres and weigh three tonnes.Paul, G.S., 2010, ''The Princeton Field Guide to Dinosaurs'', Princeton University Press p. 238 ''Edmontonia'' had small, oval ridged bony plates on its back and head and many sharp spikes along its sides. The four largest spikes jutted out from the shoulders on each side, the second of which was split into subspines in ''E. rugosidens'' specimens. Its skull had a pear-like shape when viewed ...
