Chassternbergia rugosidens
Opinions are split as to whether Chassternbergia represents a valid genus. On one side is Dr. Robert Bakker who plucked its remains from Edmontonia longiceps based upon differences in skull proportions and age then tagged them "Edmontonia (Chassternbergia) rugosidens" in 1988 and George Olshevsky who severed its Edmontonia ties altogether when he coined Chassternbergia in 1991. On the other side is everyone else.
Bakker also erected the family Edmontoniinae to house Chassternbergia, Edmontonia and Denversaurus (the latter of which is probably a specimen of Edmontonia too) and nested it within the Stegosauria. Neither Chassternbergia nor Edmontoniinae have received much in the way of support from fellow paleontologists and more often than not this critter will be listed as Edmontonia rugosidens and classified as a nodosaurid.

Chas (Charles) Sternberg's rough tooth Etymology
Chassternbergia is named in honor of American-Canadian vertebrate paleontologist Charles Mortram Sternberg (1885-1981) - "Chas" being a slang term for "Charles".The species epithet, rugosidens, is derived from the Latin "rugosus" (rough, wrinkled) and "dens" (tooth), named for the rough surface of its teeth.
Discovery
The remains of Chassternbergia were discovered in the lower Dinosaur Park Formation of Alberta, Canada, by Charles Mortram Sternberg.
