Beelemodon

"Beelemodon" is the informal name given to a genus of undescribed dinosaur from the Late Jurassic. It was possibly a coelurosaur. The fossils of "Beelemodon" consist of one partial skeleton, which was found in the U.S. state of Colorado. The name first appeared in print in 1997, when paleontologist Robert T. Bakker mentioned it during a symposium for the Academy of Natural Sciences. Until the animal is fully described in a formal scientific paper, "Beelemodon" remains a nomen nudum.
