Ornithopods

Ornithopods of the Morrison Formation
Genus	Species	State	Member	Material	Notes	Images
Camptosaurus	C. amplus	WY			A species named for a large foot found at Como Bluff.	Othnielosaurus
	?C. depressus	WY		"Illia and vertebrae."	The ?C. depressus remains may be from non-Morrison strata.
	C. dispar	CO OK UT WY		"[Twenty-five to thirty] disarticulated skull elements, some with associated postcrania, approximately [ten] partial, articulated skeletons, juvenile to adult."
Drinker	D. nisti	WY		"Partial skull and postcranial skeleton."	A basal hypsilophodont about 2 m long, slightly smaller than Othnielosaurus. It is distinguished from other Morrison Ornithopods by the complexity of its tooth denticles.
Dryosaurus	D. altus	CO UT WY	Brushy Basin	The remains of many individuals have been uncovered, with some sites containing hundreds of bones from Dryosaurus of multiple age groups.	A large dryosaurid iguanodont up to 2.4 m (7.9 feet) long and 114 kg (251 lbs) in weight. It was physically similar to Othnielosaurus, although larger and with more derived teeth.
Nanosaurus	N. agilis	CO WY			A small ornithopod, possibly a hypsilophodont
Othnielia	O. rex	CO UT WY		"[Two] partial skeletons, postcranial elements, teeth."	A small hypsilophodont 2 m in length.
Othnielosaurus	O. consors				A basal hypsilophodont about 2 m long.
Uteodon	U. aphanoecetes	UT	Brushy Basin
Uncontroversial ootaxa Reports
Preprismatoolithus	P. coloradensis	CO	Salt Wash	Eggshell present in great abundance at the so-called "Young Egg Locality" which seems to have been a dinosaur nesting ground. Congeneric eggshell fossils are found at additional Colorado sites including the Fruita Paleontological Area, the Uravan Locality and Garden Park.	P. coloradensis is described by John Foster as being "of the prismatic basic type," with subspherical eggs about 10cm (4 inches) in diameter. This oospecies has been attributed to "hypsilophodontid" dinosaurs, although a lack of associated embryo material currently makes confirming the egg-layer's identity impossible.
Uncontroversial ichnotaxa Reports
Anomoepus		CO			Morrison Anomoepus lack the handprint impressions found associated with earlier instances of the ichnogenus in New England.
Dinehichnus		UT	Saltwash	Multiple Dinehichnus trackways have been discovered. The tracks run parallel to one another, indicating that the trackmaker was at least somewhat of a social animal.	Dinehichnus are attributed to dryosaurids. The tracks preserve feet characterized by widely splayed toes and that are rotated somewhat toward the midline of the trackmaker's body. Each track is accompanied by "distinct ... heel impressions".

Discredited taxa or combinations
Genus	Species	State	Member	Material	Notes	Images
Camptonotus	C. dispar				The original name for Camptosaurus, which was preoccupied by a cricket.
Camptosaurus	C. aphanoecetes	UT	Brushy Basin		Reclassified as Uteodon.
	C. browni				Junior synonym of C. dispar.
	C. medius				Junior synonym of C. dispar. Lack of fusion in the neural arches of the type specimen's vertebrae indicate the specimens were from a juvenile.
	C. nanus				Junior synonym of C. dispar. Lack of fusion in the neural arches of the type specimen's vertebrae indicate the specimens were from a juvenile.
"Laosaurus"	L. altus				Now known as Dryosaurus altus
L. celer	WY			Considered dubious due to fragmentary remains.
L. consors
"L. gracilis"				Considered dubious due to fragmentary remains.
Tichosteus	T. aequifacies	CO		"Vertebrae."
	T. lucasanus	CO	"Vertebra."
