Sidersaura was a huge, long-necked plant-eater that lived in what is now Argentina. It may have been one of the biggest members of its dinosaur family, reaching about the length of a school bus. Its star-shaped tail bones gave it the name 'star lizard'.1

Sidersaura had a hole between its forehead and top of the skull called a frontoparietal foramen, which is rare among sauropods. Only a few other long-necked dinosaurs like Apatosaurus have it.1

Its thigh bone (femur) was 1.55 metres (5.1 feet) long, making it the biggest known of any rebbachisaurid dinosaur.1

The bones of four Sidersaura individuals were discovered together, including one found just 20 metres (66 feet) from the skeleton of the giant meat-eater Meraxes.1

Sidersaura belongs to a group called rebbachisaurids, which mostly lived in the southern continents. It was one of the last of its kind before they went extinct.1 2

The star-shaped haemal arches (bones under the tail) of Sidersaura earned it the name 'star lizard'. No other named dinosaur has exactly this shape.1

Sidersaura lived about 106 million years ago during the Early Cretaceous period, in a region that is now the desert-like Huincul Formation in Argentina.3 2

Anc discutà: Scientists are still debating exactly how Sidersaura is related to other rebbachisaurids, especially because it has some features that are also seen in titanosaurs.1 2
