About: Tawa (dinosaur)   Sponge Permalink

An Entity of Type : owl:Thing, within Data Space : 134.155.108.49:8890 associated with source dataset(s)

Tawa was estimated to have been 2 m (6.5 ft) long, almost 2.5 feet at the hips. Other estimates suggest that Tawa weighed 40 kilograms (88 pounds) at most.[4] The holotype, a juvenile individual, cataloged GR 241, consists of a mostly complete but disarticulated skull, forelimbs, the pectoral girdle, a partial vertebral column, hindlimbs, the pelvic girdle, ribs, and gastralia. The determination was made that this specimen is a juvenile based on the presence of an open braincase and unfused neurocentral sutures.[3] An isolated femur GR 244 suggests that adults were at least 30% larger than the juvenile holotype. Tawa preserves characters that can be associated with different dinosaur taxa. It's skull morphology resembles that of coelophysoids and the illium approximates that of a herrerasa

abstract
  • Tawa was estimated to have been 2 m (6.5 ft) long, almost 2.5 feet at the hips. Other estimates suggest that Tawa weighed 40 kilograms (88 pounds) at most.[4] The holotype, a juvenile individual, cataloged GR 241, consists of a mostly complete but disarticulated skull, forelimbs, the pectoral girdle, a partial vertebral column, hindlimbs, the pelvic girdle, ribs, and gastralia. The determination was made that this specimen is a juvenile based on the presence of an open braincase and unfused neurocentral sutures.[3] An isolated femur GR 244 suggests that adults were at least 30% larger than the juvenile holotype. Tawa preserves characters that can be associated with different dinosaur taxa. It's skull morphology resembles that of coelophysoids and the illium approximates that of a herrerasaurid. Like the coelophysoids, Tawa has a kink in its upper jaws, between the maxilla and the premaxillae. With respect to limb proportion, the femur is very long compared to the tibia. A neck vertebrae adaptation in Tawa supports the hypothesis that cervical air sacs predate the origin of the taxon Neotheropoda and may be ancestral for Saurischians, and also links the dinosaurs with the evolution of birds. Compared to earlier dinosaurs like Herrerasaurus and Eoraptor, Tawa had a relatively slender build. The following were assigned as paratypes: a nearly complete skeleton (GR 242); femora, pelvis and tail (GR 155); and cervical vertebrae (GR 243).
