izinto ezimnandi

Iinyani ezimnandi

1

Seitaad's name comes from a Navajo legend about a sand monster that buried its victims in dunes.1

2

The only known fossil of Seitaad was found at the base of a collapsed sand dune, which may have buried the animal after it died.1

3

Seitaad is one of the few early sauropodomorph dinosaurs known from North America.1

4

The species name ruessi honors Everett Ruess, a young artist and explorer who disappeared in southern Utah in 1934.1

5

Seitaad had a plate-like bone on its shoulder blade that helped support its arm.1

6

This dinosaur lived during the Early Jurassic period, when the climate was warm and deserts covered much of the area.1

Umfanekiso owenziwe yi-AI obonisa indlela Seitaad esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.
ubuzile

Eyona mibuzo ibuzwa kakhulu: Seitaad

?How big was Seitaad?

About 3 to 4.5 metres long and 1 metre tall at the hips. It weighed around 70 to 90 kilograms, about the size of a large human.2

?What did Seitaad eat?

?Could Seitaad walk on two legs?

Yes, Seitaad could walk on two legs or on all fours. It had a long neck and tail, and a large curved claw on its thumb.2

?When did Seitaad live?

Seitaad lived during the Early Jurassic Period, about 183 to 190 million years ago. That is millions of years before the famous giant sauropods like Diplodocus.2

Ukufunyanwa
Seitaad was named by scientists Joseph Sertich and Michael Loewen in 2010. The partial skeleton was found in the Navajo Sandstone of southern Utah, near a cliff dwelling called Eagle's Nest.31
Kusaxoxwa ngayo
Scientists are not sure exactly how Seitaad is related to other early sauropodomorphs, because its fossils do not give a clear family tree.1
