Utuntu dushimishije

Sarahsaurus is one of only three sauropodomorph dinosaurs known from the Early Jurassic of North America.2

Its name honors Sarah and Ernest Butler, whose generosity helped science in Texas.1

The specific name 'aurifontanalis' means 'of the gold spring', referring to Gold Spring, Arizona, where the first skeleton was found.1

Scientists used CT scans to study the skull of Sarahsaurus without damaging the fossils.1

Sarahsaurus belongs to the group Massospondylidae, which includes dinosaurs mostly found in the southern continents.2

The holotype skeleton includes a partial skull, most of the backbone, both arms, and both legs.1

Ibibazo bibazwa cyane kuri Sarahsaurus

?How big was Sarahsaurus?

Sarahsaurus was mid-sized for a basal sauropodomorph. Its vertebral column measured more than 3.1 metres (10 ft) long, and one estimate gives a total length of about 4 metres (13 ft) and a weight of 200 kilograms (440 lb).3

?What did Sarahsaurus eat?

Sarahsaurus was probably a plant-eater, but it had very large, powerful hands, which might mean it also ate some meat, making it an omnivore.3

?When did Sarahsaurus live?

Sarahsaurus lived during the Early Jurassic period, about 200 to 190 million years ago.3

?Where was Sarahsaurus found?

All Sarahsaurus fossils were found near Gold Spring, Arizona, in the Kayenta Formation.3 1

?Why is it called Sarahsaurus?

It is named after Sarah Butler, who helped fund a dinosaur exhibit, and the species name 'aurifontanalis' means 'of the gold spring', after the place where it was found.3

?Was Sarahsaurus a dinosaur?

Yes, Sarahsaurus was a dinosaur, specifically a basal sauropodomorph, a group of long-necked dinosaurs.3

Gusenya ibinyoma

Ibivugwa: Some people think Sarahsaurus was a giant, elephant-sized dinosaur.

Ukuri: Sarahsaurus was actually quite small for a sauropodomorph, only about 4 to 5 meters long and weighing as much as a black bear.4
