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:
- 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.
- "Trachodon" means "rough tooth".
- 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.
- Trachodon lived between about 77 million years ago and 73 million years ago, during the late Cretaceous period.
- Trachodon lived in North America.
- Trachodon was a herbivore (plant-eater).

Trachodon 3 features writing by some of today's most vibrant storytellers. In God's TV, a new story by Pacific Northwest Bookseller Award favorite Pete Fromm, a husband stands on the brink of fatherhood and looks into a future that's at once bright and impossible. Heather Clitheroe takes us into the mind of a clinical scientist and reveals a compellingly disordered view of the world. And In The Littlest Goat, Dan Pinkerton offers a portrait of a family man paralyzed by a fear of bridges, and over a homecoming weekend, peels back the layers to expose deeper fears that we all carry. In Printer's Devil, an essay on artisan culture, Ray Scanlon recalls his summer apprenticing in a print shop when moveable type was still the industry standard. A portfolio of mixed-media visual art by Marianne Dages rounds out our third issue. |

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Trachodon (meaning "rough tooth") is a dubious genus of hadrosaurid dinosaur based on teeth from the Campanian-age Upper Cretaceous Judith River Formation of Montana, U.S.A. It is a historically important genus with a convoluted taxonomy that has been all but abandoned by modern dinosaur paleontologists. Despite being used for decades as the iconic duckbill dinosaur per antonomasia the material it is based on is composed of teeth from both duckbills and ceratopsids (their teeth have a distinctive double root), and its describer, Joseph Leidy, came to recognize the difference and suggested limiting the genus to what would now be seen as ceratopsid teeth. Restricted to the duckbill teeth, it may have been a lambeosaurine. |
