Leonerasaurus was a small, plant-eating dinosaur that lived in what is now Argentina. It had a long neck and walked on four legs, but it was much smaller than its giant sauropod cousins. This dinosaur helps scientists understand how the biggest dinosaurs evolved.2 1

Leonerasaurus had four vertebrae in its sacrum (the part of the spine that connects to the hips), just like giant sauropods, even though it was much smaller.1

Its teeth were spoon-shaped and had no serrations, which is a feature seen in early sauropods.1

The fossil was found with many bones still connected, including the neck, back, hips, and shoulder bones.1

Leonerasaurus lived during the Early Jurassic period, about 199 to 184 million years ago.2 4

It was a close relative of sauropods, but it was not a true sauropod itself.1

The only known specimen is a subadult, meaning it was not fully grown when it died.2
