Edmontonia was an armoured dinosaur, a part of the nodosaur family from the Late Cretaceous Period. Its name means 'of Edmonton', as it was discovered in Edmonton, Alberta, Canada.
[edit] Discovery and species
The type species of Edmontonia, E. longiceps was discovered in 1924 by George Paterson. It wasn't named until 1928 by C. M. Sternberg. E. rugosidens, formally named by Gilmore in 1930, is reported from the Aguja formation in Texas. Edmontonia species
- E. longiceps (type)
- E. rugosidens
Edmontonia australis, known from cervical scutes only, is a nomen dubium.[1]
[edit] Paleobiology
Edmontonia was bulky and tank-like at roughly 23ft (7m) long and 6ft (2m) high. It had bony plates on its back and head, many sharp spikes along its back and tail and 4 large spikes jutting out from its shoulders on each side. These large spikes were probably used in contests of strength. To protect itself from predators, it probably would have crouched down on the ground to minimise the possibility of attack to its defenceless underbelly.
