Abstract: Call that a sauropod... Sauropods are everybody's archetypal dinosaur: bulky bodies, long necks and long tails. This also reflects the view that they were unspecialized herbivores without significant ecological differences between groups. The new find of a short-necked sauropod from the Late Jurassic of Patagonia, a time of continental break-up and environmental change, shows that not all lineages of sauropods followed the trend towards elongation of the neck. The newly discovered fossils suggest that sauropods were in fact able to adapt rapidly to new environments. By establishing a niche in which a short-necked herbivore could operate, a range of herbivores in a single environment.
