Astigmasaura is a medium-sized rebbachisaurid sauropod dinosaur from the Late Cretaceous period of what is now Argentina. Rebbachisaurids had highly pneumatized bones that helped them to hold their weight on their four pillar-like legs, and extremely long tails. Astigmasaura was likely a ground-level browsing herbivore. © TotalDino · CC BY 4.0 · Wikimedia
