Theiophytalia kerri Brill & Carpenter, 2006 - ornithopod dinosaur skull from the Cretaceous of Colorado, USA. (YPM 1887, public display, Garden of the Gods visitor center, Colorado Springs, Colorado, USA) This skull is the holotype and only known specimen of an entire genus of ornithopod dinosaurs, Theiophytalia. Ornithopods were herbivorous dinosaurs. From exhibit signage: A Brand New Dinosaur Species Theiophytalia kerri What we know about the dinosaur fossil - so far: It is the only Theiophytalia kerri fossil known to exist in the world. It is a brand new genus and species of dinosaur. Theiophytalia kerri means "belonging to the Garden of the Gods". "Theios" is a Greek word that means "belonging to the gods" and "phytalia" means "garden". "kerri" honors James Hutchinson Kerr (pronounced "Care"), who discovered the dinosaur fossil. Theiophytalia was a medium-sized dinosaur, measuring about 30 feet from head to tail. It was found in 1878 in the Garden of the Gods in the lower Lytle Member of the Purgatoire Rock Formation of the Dakota Group. The dinosaur fossil skull is from the Aptian-Albian Age of the Cretaceous Ear, 125 - 100 million years old.
Dinosaur Fossil Discovered, then Forgotten 1878 - James Kerr, geology professor at Colorado College, finds a fossil skull "in one of the ridges east of the red rocks of the Garden of the Gods." 1886 - O.C. Marsh, famous 1800s dinosaur collector from Yale University, obtains the fossil skull from James Kerr, identifies it as a Camptosaurus dinosaur, and sends the fossil to the Yale Peabody Museum in New Haven, Connecticut. 1886 - 1995 - While the dinosaur fossil skull safely rests in the Yale Museum for many decades, knowledge of its existence is forgotten in Colorado Springs. Rediscovery - 117 years later 1994 - Colorado Springs City park staff research new exhibits for the Garden of the Gods Visitor and Nature Center, set to open in 1995. They meet with Doctor Kirk Johnson, curator of paleontology at the Denver Museum of Nature & Science. 1995 - Kirk Johnson refers the park staff to his museum colleague Doctor Ken Carpenter, expert dinosaur scientist. Doctor Carpenter remembers seeing in his files "something about a dinosaur fossil found in Garden of the Gods" and mails the following article to park staff. Camptosaurus amplus No. 1887, Yale Museum, consisting of portions of the skull and lower jaw. It was collected from deposits in the Garden of the Gods, Colorado Springs, Colorado. With this specimen was found the following note in Professor O.C. Marsh's handwriting, "Part of this animal and various Sauropoda bones were taken out by Professor Kerr in 1878." A Case of Mistaken Identity Reveals a Brand New Dinosaur! 1996 - Kirk Johnson (a Yale alumnus) secures permission to hand-carry the Camptosaurus fossil from the Yale Peabody Museum to Denver so that Ken Carpenter can make a cast (a precise replica) of the fossil. Doctor Carpenter notices irregularities in the Camptosaurus fossil and decides to re-examine the fossil when his schedule permits. 1997 - The Camptosaurus fossil replica is given to the City of Colorado Springs and is exhibited at the Garden of the Gods Visitor and Nature Center. 2006 - Doctor Carpenter and his associate Kathleen Brill reassess the fossil skull and note that it differs from other Camptosaurus skulls in several significant ways, such as the narrower mouth and snout, and the position of the nasal openings, and the bony structures over the eyes. Also, microscopic identification of the rock matrix clinging to the fossil, and research of archival maps, reveal that the fossil skull was actually found in the lower Dakota Rock Formation, not the Morrison Formation as originally reported in the 1800s. The skull is from a dinosaur that lived in the Cretaceous Ear and can't be a Jurassic Era Camptosaurus. Doctor Carpenter's exacting research reveals that the dinosaur skull is a brand new genus and species of dinosaur! He names it Theiophytalia kerri. 2008 - The Theiophytalia kerri is proudly re-exhibited at the Garden of the Gods Visitor and Nature Center.
