"Illia and vertebrae."^[4]

The ?C. depressus remains may be from non-Morrison strata.^[2]

C. dispar^[5]

"[Twenty-five to thirty] disarticulated skull elements, some with associated postcrania, approximately [ten] partial, articulated skeletons, juvenile to adult."^[4]

Drinker^[1][8]

D. nisti^[8]

• WY^[3][9]

"Partial skull and postcranial skeleton."^[10]

A basal hypsilophodont about 2 m long,^{[citation needed]} slightly smaller than Othnielosaurus.^[8] It is distinguished from other Morrison Ornithopods by the complexity of its tooth denticles.^[8]

Dryosaurus^[1]

D. altus^[5]

• CO^[6][11]
• UT^[5]
• WY^[3][12]

• Brushy Basin^[13]

The remains of many individuals have been uncovered, with some sites containing hundreds of bones from Dryosaurus of multiple age groups.^[11]

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.^[12]

Nanosaurus

N. agilis

• CO^[6]
• WY^[3]

A small ornithopod, possibly a hypsilophodont

Othnielia^[5]

O. rex^[5]

• CO^[6]
• UT^[5]
• WY^[3]

"[Two] partial skeletons, postcranial elements, teeth."^[14]

A small hypsilophodont 2 m in length.

Othnielosaurus^[1]

O. consors

A basal hypsilophodont about 2 m long.

Uteodon

U. aphanoecetes^[15]

• UT^[15]

• Brushy Basin^[15]

Preprismatoolithus^[16]

P. coloradensis^[16]

• CO^[16]

• Salt Wash^[16]

Eggshell present in great abundance at the so-called "Young Egg Locality" which seems to have been a dinosaur nesting ground.^[16] Congeneric eggshell fossils are found at additional Colorado sites including the Fruita Paleontological Area, the Uravan Locality and Garden Park.^[16]

P. coloradensis is described by John Foster as being "of the prismatic basic type,"^[16] with subspherical eggs about 10cm (4 inches) in diameter.^[17] This oospecies has been attributed to "hypsilophodontid" dinosaurs, although a lack of associated embryo material currently makes confirming the egg-layer's identity impossible.^[16]

Anomoepus

• CO^[18]

Morrison Anomoepus lack the handprint impressions found associated with earlier instances of the ichnogenus in New England.^[18]

Dinehichnus^[18]

• UT^[18]

• Saltwash^[18]

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.^[18]

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".^[18]

Camptonotus

C. dispar

The original name for Camptosaurus, which was preoccupied by a cricket.

Camptosaurus^[1]

C. aphanoecetes^[15]

• UT^[15]

• Brushy Basin^[15]

Reclassified as Uteodon.

C. browni^[19]

Junior synonym of C. dispar.^[19]

C. medius^[2]

Junior synonym of C. dispar.^[19] Lack of fusion in the neural arches of the type specimen's vertebrae indicate the specimens were from a juvenile.^[2]

C. nanus^[2]

Junior synonym of C. dispar.^[19] Lack of fusion in the neural arches of the type specimen's vertebrae indicate the specimens were from a juvenile.^[2]
