izinto ezimnandi

Iinyani ezimnandi

Arkansaurus is the only dinosaur fossil ever described from the state of Arkansas.1

Its foot bones show a greenstick fracture, which is the first time such a healed break has been found in a dinosaur fossil.1

The dinosaur was discovered in 1972 by Joe B. Friday on his farm, and it was named after him and the state.1

Arkansaurus was a basal ornithomimosaur, meaning it was an early relative of the ostrich-like dinosaurs, but not as advanced.1

It lived along the shoreline of a shallow sea that covered parts of North America during the Early Cretaceous.2

Scientists think Arkansaurus could run fast because its foot bones were long and slim, with three toes.2

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

Arkansaurus was a very fast runner, with strong back legs and an ostrich-like build.4

?When did Arkansaurus live?

Arkansaurus lived during the Early Cretaceous period, about 113 to 100 million years ago.1 4

?Is Arkansaurus a dinosaur?

Yes, Arkansaurus is a dinosaur. It is an ornithomimosaurian theropod dinosaur.1

Inyaniso ngeentsomi

Intsomi: Some people think Arkansaurus was a meat-eater like a raptor.

Inyaniso: It was actually an omnivore, eating plants, insects, and maybe eggs, based on its beak and toothless mouth.2

Kwiingcali zeedayinaso

Igama lenzululwazi: Arkansaurus
Inikwe igama ngu:: Hunt and Quinn 20186
Iqela: Iidayinaso-nciniba
Usapho / iclade: Ornithomimosauria6
Ukuhlelwa: Theropoda > Ornithomimosauria6
Ubudala bamatye: 113 ukuya ku-100 izigidi zeminyaka (Albian)6
Amazwe: iUSA6
Iirekhodi zeefosili: 1 kwi-Paleobiology Database6
Ukufunyanwa: The foot bones were found in August 1972 by Joe B. Friday in a gravel pit near Lockesburg, Arkansas. Dr. James Harrison Quinn studied them and named the dinosaur Arkansaurus fridayi, but he died before publishing. The name was officially published in 2018 by paleontologists ReBecca Hunt-Foster and James Harrison Quinn.1
Kusaxoxwa ngayo: Scientists are not sure exactly what Arkansaurus looked like because only foot bones have been found. Its appearance is guessed from related dinosaurs.2
