Allosaurus fragilis Marsh, 1877

11844 Cranium, mandible, and the greater portion of the skeleton lacking the forelimbs and a few other bones; from the Morrison Formation of Carnegie Museum Quarry at Dinosaur National Monument, north of Jensen , Uintah County, Utah (DNM 202). The partial skull, cervicals, scapula-coracoid, and some ribs were originally catalogued CM 11868 but they are part of this skeleton. The specimen was mounted and placed on exhibition in 1938. The right fibula was supplied from DNM 171 found near the skeleton and likely belonging to it. The incomplete skull was replaced in the mount by a cast of one from the same quarry, UU 6000. The forelimbs were cast from USNM 4734. Pictured by Kay—Carnegie Mag. (1940 a), 13:303-304; mentioned by Stovall and Langston—Amer. Midland Nat. (1950), 43:713.

The following specimens all came from the Morrison Formation at the Carnegie Museum Quarry at Dinosaur National Monument near Jensen, Utah, and were collected by Douglass et al., 1909-1923.

21703 Cranium, presacrals, caudals, ilium, ischium (DNM 22).

11843 Cranium (only partially prepared), several centra, ribs, 1 coracoid, and other parts perhaps belonging to a young individual of this genus (DNM 366).

3387 Teeth and fragments (DNM 2).

3382 A tooth (DNM 14).

3383 Small vertebrae etc., perhaps belonging to this form (DNM 187).

33965 Two anterior caudal centra, four spines, three arches (DNM 120/C).

38341 Caudal and claw (marked DNM 130, probably really 102).

21705 Caudal centrum (DNM 193/A) .

33957 Two caudals (with DNM 232).

21757 Three caudals .

33901 Several vertebrae.

33903 Gastralia perhaps belonging to this form (associated with DNM 210).

21713 Left ischium and a metatarsal and other material not yet prepared (DNM 302, part).

21726 Left femur (DNM 39/60L).

21769 Distal end of right femur (DNM 120/N) .

37004 Distal end of metatarsal (DNM 270/26) .

38349 Several incomplete metatarsals (?DNM 197, part).

10002 Proximal end right tibia and fibula from the Morrison Formation, east of Nielsen Gulch, northeast of Carnegie Museum Quarry at Dinosaur National Monument and not far from the latter (DNM 165). The horizon is the same as that of the main quarry. The fibula was incorporated into the mounted skeleton CM 11844.

Collected by Douglass et al., 1913

82 Anterior caudal centrum from the Morrison Formation of Carbon County, Wyoming. It was brought back to Pittsburgh in 1899 by W. J. Holland from his first trip to the West to obtain dinosaurs for the museum. It is of historical importance as the first dinosaur specimen (aside from a cast) to be entered into the museum catalogue. A small section of a sauropod rib found with the centrum bears the same catalogue number.

Collected by Holland, 1899

21736 A large right scapula-coracoid probably belonging to this species. The data concerning it has been lost, but it may have come from the Morrison Formation at Dinosaur National Monument , despite its somewhat unusual coloration.

1254 Both ischia to which has been added a right premaxilla, two teeth, two sacral vertebrae, left humerus, four metatarsals, and several phalanges. These are part of a skeleton of a small individual, some bones of which were formerly catalogued as part of the “catchall” no. 1255 (p. 15) from Quarry N, Freezeout Hills , Carbon County, Wyoming. Many vertebrae and other parts of the skeleton were poorly preserved and were discarded.

2045 A femur from the Morrison Formation of Wilson Creek , Colorado.

36037 Caudal. Quarry B, Red Fork of the Powder River , Johnson County, Wyoming.
