[D] Stephanosaurus [Su] [dG]
Describer
Lambe, 1914
Time
Cretaceous Late Campanian
Classification
Ornithischia Ornithopoda Hadrosauridae Nomina Dubia
Diet
Herbivore
Fossilsite
Judith River Wedge, Alberta, Canada
Info
Genus - Skull
\\\\\\\"crowned lizard\\\\\\\" Named for the helmet-like nasal bones that crowned its skull; Lambe proposed the name in 1914 for two imperfect crested skulls that he incorrectly associated with skeletal material earlier identified as Trachodon marginatus.
However, Brown (and then Gilmore) showed that the type material attributed to Stephanosaurus is not definable and came from different individuals of more than one type of hadrosaur.
Parks proposed the new name Lambeosaurus in 1923 based on the helmet-crested skull material only. \\\\\\\"Trachodon marginatus\\\\\\\" is now a nomen dubium.
