[D] Gallimimus mongoliensis
Describer
Barsbold, 1998
Time
Cretaceous Late
Classification
Saurischia Theropoda Tetanurae Coelurosauria Ornithomimosauria Ornithomimidae Nomina Dubia
Diet
Omnivore
Fossilsite
Baynshirenskaya Svita, Bayshin Tsav (Baishin Tsav) South-eastern Mongolia
Length
4 meter
Info
(\\\"Gallus (chicken) mimic from Mongolia\\\")
Gallimimus mongoliensis is distinguished from Gallimimus bullatus on the following characters: relatively straight claws, humerus (upper arm bone) and ulna (lower arm bone) are shorter, thus entire arm structure is much meager, smaller skull
Since Gallimimus mongoliensis had shorter forelimbs with rather straight claws, it is suggested that this animal was not good at grasping the prey in comparison to Gallimimus bullatus. This animal possibly had different eating behavior from that of Gallimimus bullatus
Kobayashi and Barsbold (2006) Ornithomimids from the Nemegt Formation of Mongolia. J. Paleont. Soc. Korea. Vol. 22, No. 1, (2006) : p. 195-207.
\\\"A nearly complete skeleton of ornithomimid (MPD 100/14) was found from the Baishin Tsav of southeastern Mongolia (where a primitive but toothless ornithomimosaur, Garudimimus brevipes, was discovered) and was imfornally called Gallimimus mongoliensis by Barsbold. It possesses derived features (e.g., lack of teeth, subequal metacarpals, and arctometatarsalian condition of metatarsals) of Ornithomimidae. It also differs from Gallimimus bullatus in having a small skull, more proximally positioned medial divergence of metacarpal I, nearly straight manual unguals, and shorter metatarsals. The length ratio of manus/humerus is 0.91, greater than Gallimimus bullatus, but a common ratio for ornithomimosaurs. These suggest that this ornithomimid (MPD 100/14) is not Gallimimus but belong to another genus, perhaps a new taxon.\\\"
