Amargasaurus, the spiny short-necked Sauropod Dinosaur from South America

Описание: When we look back through time, we see many avenues of evolution that we consider strange, for we do not tend to see such things in our day to day lives; however, strange is what life is all about, trying new things, getting to know the environment, striving to reach the top rungs of the jungle gym of life. The Mesozoic, and all the different forms of Dinosaurs were no different, and they produced their fair share of oddities, one of which had a spectacular protrusion from its neck, the “Bitter Reptile from La Amarga” Amargasaurus!
