酷東西

趣味知識

Mahuidacursor is known from a partial skeleton that includes neck and back bones, part of the shoulder, and the right arm.2

The name Mahuidacursor comes from the Mapuche language word for 'mountain' and the Latin word for 'runner'.1

This dinosaur lived during the Santonian stage of the Late Cretaceous, about 86 to 83 million years ago.3

Histology (study of bone tissue) shows the only known Mahuidacursor was a sexually mature adult, but not fully grown.2

Mahuidacursor had a strongly bowed upper arm bone and a weakly developed deltopectoral crest, features shared with other South American ornithopods.2

Scientists think Mahuidacursor was a ground-dwelling, egg-laying dinosaur that moved actively on land.3

關於 Mahuidacursor 最常被問的問題

?How big was Mahuidacursor?

It was a medium-sized ornithopod, but scientists do not know its exact length or weight because only a partial skeleton has been found.1 5

?What did Mahuidacursor eat?

It was a plant-eating dinosaur, as it belonged to the ornithopod group of herbivores.1

?Could Mahuidacursor run fast?

Yes, it had a slender body and long legs, and scientists think it was a fast runner adapted for a cursorial (running) lifestyle.5
