ເລື່ອງໜ້າຮູ້ມ່ວນໆ
Jeholosaurus had a very fast tooth replacement rate, with new teeth growing every 46 days, faster than most early plant-eaters.1
Its eye socket was huge, making up 40% of the skull length, which is a sign it was a young animal.1
The front teeth were narrow and long, like a meat-eater's, but the back teeth were fan-shaped for chewing plants.1
The hip bone pointed backward, which is typical for ornithischian dinosaurs, but it also had a forward-pointing bone that supported its belly.1
All known fossils are from young animals, so scientists don't know exactly how big an adult could get.1
ຄຳຖາມທີ່ຖືກຖາມຫຼາຍທີ່ສຸດກ່ຽວກັບ Jeholosaurus
?How big was Jeholosaurus?
The known fossils are from young animals, so the adult size is unknown. The largest specimen is about 71 centimetres long, with a skull of 6.3 centimetres.1
?What did Jeholosaurus eat?
It mostly ate plants, using its beak and fan-shaped cheek teeth. But its front teeth were sharp like a meat-eater's, so it might have also eaten small animals or bugs.1
?Was Jeholosaurus a dinosaur?
Yes, Jeholosaurus was a small ornithischian dinosaur, a group of plant-eating dinosaurs with bird-like hips.1
?Why did Jeholosaurus have a beak?
The beak helped it nip off plants. Its cheek teeth were fan-shaped for grinding them up, and it may have had fleshy cheeks to hold food while chewing.1
ໄຂຄວາມເຊື່ອຜິດ
ຄວາມເຊື່ອຜິດ: Jeholosaurus was a meat-eater because it had sharp front teeth.
ຄວາມຈິງ: Its back teeth were for chewing plants, and it likely ate plants, though it might have eaten some insects or small animals too.1

- Scientists still debate whether Jeholosaurus was a plant-eater or an omnivore, because its front teeth were sharp and its back teeth were for plants.1
