Scientific Classification
 
Arguably
nomen nudum
Some scientists consider this a nomen nudum - a scientific name for which an adequate description has not been published
 
  Kingdom Animalia
  Phylum Chordata
  Class Sauropsida
  Superorder Dinosauria
  Order Ornithischia
  Family Hardrosauridae
  Subfamily (?) Lambeosaurinae
  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).

Excerpt: The name Aachenosaurus refers to two fossilized fragments of material that were originally thought to be jaw fragments from a duck-billed dinosaur (a hadrosaur ). However, the fossils turned out to be petrified wood , to the great embarrassment of the discoverer. The fossil's name means "Aachen lizard", named for the Aachenian deposits of Moresnet (which was a neutral territory between Belgium and Germany ), where the fossils were found. A synonym of Aachenosaurus is Aachenoxylon , which was coined by Dr Maurice Hovelacque in 1889/1890. History Aachenosaurus was found and named by the scientist (and abbé) Gerard Smets, on October 31, 1888, who named the type species Aachenosaurus multidens . Based on these fragments he determined that the specimen was a hadrosaur reaching an estimated 4 to 5 meters in length which might have had dermal spines. He defended this conclusion, citing that the fossils had been examined visually with the naked eye, magnifying lenses and with the microscope. However, his error was soon demonstrated by Louis Dollo . Smets at first tried to defend his original identification but was again proven wro...
