The remains of a ampelosaurio found in 2007 on the site of Lo Hueco have allowed the 3D reconstruction of the brain, which has proved to be extremely small, as recorded by an investigation which has involved the Superior Council for Scientific Research and Publishing PLoS ONE.
The ampelosaurio belongs to the group of sauropods, large dinosaurs that came to colonize large areas of the planet during the Mesozoic Era. Specifically, it is a titanosaurus, a group of dominant herbivores in the latter half of the Cretaceous, ie, the final stage of the Mesozoic.
Early sauropods emerged about 160 million years before the appearance of ampelosaurio. However, despite being the result of a long evolution, the brain shows no remarkable ampelosaurio development. The researcher at the National Museum of Natural Sciences, CSIC Fabien Knoll, co-author, said "this lizard could have reached up to 15 meters long, however, his brain did not occupy more than 8 centimeters." For CSIC researcher, "the increase in brain size has not been favored during the evolution of sauropods."
Another prominent feature of the reconstruction of Cuenca lizard brain is the small size of the inner ear. According to Knoll, "this could indicate that the ampelosaurio not be quickly adapted to move both eyes or head or neck".
So far, only one species of this genus, Ampelosaurus atacis, which was discovered in France is known. However, the differences between the Spanish and French fossil do not exclude the possibility that it could be two different species. Knoll believes that "more remains would be necessary to ensure that it is a new species." Therefore, the team has classified as Ampelosaurus copy sp., Leaving open a specific level identification.
