MADRID, 27 Researchers from the National Council of Scientific and Technical Research (CONICET) of Argentina have discovered a new dinosaur, the Leonerasaurus taquetrensis, according to the organization. Thus, a recent study published in the journal PLOS One shows the discovery of the remains of new dinosaur to complete one of the gaps "most important" in the evolutionary history of Sauropodomorpha and which is the transition between the primitive and the giants prosauropods sauropods.
Specifically, he explains that sauropods are among the best known groups of dinosaurs, giant four-legged herbivores, long neck and long tail, which inhabited the Earth during the Jurassic and Cretaceous, and evolved from much smaller species, graceful and biped known as prosauropods. " However, scientists said that was still unclear evolutionary chain transformations between primitive prosauropods and giant sauropods, as no intermediate forms were found in the fossil record.
CONICET researcher in the Paleontological Museum Egidio Feruglio, Diego Pol, said that "details of their teeth and suggest that pelvic anatomy is much closer to the origin of the sauropods that prosauropods previously known." The Leonerasaurus has been discovered in the Sierra de Taquetrén, in north central Chubut Province (Argentina).
Pol has indicated that "was discovered within the framework of an exploration project Jurassic rocks of Patagonia."
