Eoraptor lunensis (english)
Description of dinosaur
A dinosaur omnivore from lived 230 million years ago, found in the period Carnian-Triassic. His fossils (Holotype PVSJ-512) was found in the Ischigualasto region, in the year 1991 for the paleontologist Ricardo Matínez and describe two years later for the paleontologist Paul Sereno and his team.
About his size, his proportions are similar to Panphagia protos, his weight was about 10 kg while his size, from head to tail, was about 1 m. The name of the genus (Eoraptor) it means “dawn thief” and of his specie (lunensis) it means to “Valle de la luna”, place where it was found. Very similar to Panphagia, Eoraptor is found in the middle of first dinosaurs that belong sauropodomorph.
Brief history of his find
Steve Brusatte narrates in his book Rise and fall of the dinosaurs, a quirky history about Eoraptor discovery. He narrates that during an excursion, by team of Paul Sereno, in Ischigualasto, one of his assistant named Ricardo Martínez, found a rock of the size of a fist. He was about to throw its, but he noticed something shiny and pointed come out of the rock. When he saw again down, he realized that he had torn off the head of the skeleton of dinosaur; that pointed detail was a dinosaur tooth. Two years later of found, the specie was described for Paul Sereno and his team with the name Eoraptor. Since then Eoraptor had become an important picture for video games of Jurassic Park franchise, for example, Jurassic Park III Park Builder.
Own Characteristics
The paleontologist Jose Bonaparte pointed the studied fossil (the holotype PVSJ-512) like a juvenile specimen. About his diet, in many books Eoraptor described like a carnivorous, in many documentaries (As to series “victors of evolution”) they even show him feeding of insects, however, during a course of Sebastián Apesteguía, I heard him to mention like a herbivorous dinosaur, Brusatte also pointed like omnivore dinosaur (similar to Panphagia). The arms of Eoraptor lunensis looked more robust than Eodromaeus a dinosaur contemporary; however, a shared feature by both species, is that the tibia was longer than the femur.
