A primitive predatory dinosaur

lovethee History

This species provides the first good skulls, two to be precise, of a primitive predatory dinosaur. (walking dinosaur suit)The type includes a head with jaws that is missing most of the roof pieces, plus some tail bones. Another specimen with a complete but crushed skull has been Ianguishing in the MCZ for years, the skeletal parts-including the bird-style shoulder blade and humerus mentioned abovewere described by Donald Brinkman and Hans-Dieter Sues.2 The long, low skulls of these individuals look similar and may be the salne species. The most interesting item is the size of the tooth at the middle of the upper jaw; it was a good-sized fang that probably poked out from under the lips. Otherwise the head was strongly built, especially in the snout and jaws. In terms of evolutionary development,(realistic dinosaur costume) Frenguelh’sourus was clearly intermediate to staurikosaurs and herrerasaurs. Fernando Novas noted its similarity to the latter, while Brinkman and Sues emphasize the similarity of its hip’s ischium to the former. I think it is a primitive herrerasaur because the MCZ vertebrae have their kind of distinctive hour-glass shape. Since I do not think hemerasaurs are theropods, this is not considered to be the first known theropod-contrary to the suggestion by Novas that it was. Frenguellrsaums shared its Ischigualasto habitat with its close relatives lsch isaurus and Flerreroscurus.

 

one of the most unusual and speciabzed of paleodinosaurs. A big-toothed jawbone Reig referred to this species may not really belong, so we know nothing for certain of its head. The one shown on the skeletal restoration is drawn after Freng’uelhsaurus, as are the humerus and some of the forward vertebrae. (Animatronic dinosaur) The slender shoulder blade is taken from a newly identified relative, and it parallels those of advanced theropods and birds. The backswept pubis and well-developed antitrochanter joint surface in the hip socket each match the similar structures found in both ornithischians and protobirds. (animatronic dinosaur for sale)The pubes also have a big boot, otherwise known only in the advanced theropods. The vertebral bodies are hourglass-shaped, like those of the allosaurs. All in all, a remarkable suite of advanced features. It has been suggested that Sfcurfkosourus prfcef was a juvenile of Herrercsaurus, but the discovery of juvenile Herreroscurus hips and other differences show that this was not so. It has even been offered that henerasaurs were early brontosaurs, far as it may be from reality.
