Scientific Classification
nomen dubium
Some scientists consider this a nomen dubium - a scientific name of unknown or doubtful application
  Kingdom Animalia

  Class Sauropsida
  Superorder Dinosauria
  Order Ornithischia
  Family Hardrosauridae

  Genus Trachodon
Trachodon was a herbivore (plant-eater) that lived in North America during the late Cretaceous period, about 77 to 73 million years ago.

The animal was named in 1856 by Joseph Leidy based on fragmentary fossils remains of seven teeth, one of which had a double root. Leidy choose the name Trachodon (which means "rough tooth").

Leidy himself later claim to the conclusion that the teeth were from more than one animal, and that Trachodon should be limited to the double-rooted tooth. Despite being historically important in taxonomy, and being widely known to the public at large, most paleontologists consider the genus Trachodon to be a "nomen dubium" (literally a "doubtful name" - a scientific name which is of unknown or doubtful application).

Trachodon Facts

Here is a summary of some of the key facts about Trachodon:
  1. Trachodon was a genus of dinosaur. Although Trachodon was historically important and is well-known to the general public, today many scientists consider it be a doubtful name ("nomen dubium"), and have abandoned the use of the word "Trachodon", as it has been used to refer to fossils of many unrelated animals.

  2. "Trachodon" means "rough tooth".

  3. Trachodon was a member of the Ornithischia ("bird-hipped") order of dinosaurs. What this means, is that although Trachodon was not closely related to birds, it did have similarly shaped pelvic bones.

  4. Trachodon lived between about 77 million years ago and 73 million years ago, during the late Cretaceous period.

  5. Trachodon lived in North America.

  6. Trachodon was a herbivore (plant-eater).
