Pectinodon bakkeri
(Bakker's comb tooth)Etymology
Pectinodon is derived from the Latin "pecten" (comb) and the Greek "odon" (tooth), in reference to the comb-like serrations on the rear edge of its teeth.
The
species epithet,
bakkeri, honours palaeontologist Robert Thomas Bakker.
Discovery
The first remains of
Pectinodon were discovered at "Bushy tailed blowout" in the Lance Formation of Niobrara County, Wyoming, USA.
The
holotype (UCM 38445) is a 6mm long adult tooth. Three juvenile teeth (UCM 38446, UCMP 73098, UCMP 125239) were assigned as paratypes. Referred material includes eight adult teeth (UCMP 125240-125247).
