Ibirania was a tiny sauropod, one of the smallest long-necked dinosaurs ever found. It lived in a dry, inland part of Brazil about 80 million years ago. Despite its small size, it had air-filled bones just like its giant relatives.1 2

ເລື່ອງໜ້າຮູ້ມ່ວນໆ

Ibirania is one of the smallest sauropods known, only about 5.7 metres (19 feet) long.1 2

Its bones were extremely hollow and filled with air sacs, like a bird's, which helped make it lighter.1

Scientists found fossilised parasites inside the bone canals of one Ibirania leg bone, the first time such parasites have been seen in a dinosaur.1

One Ibirania specimen had a bone infection called acute osteomyelitis, which scientists studied using CT scans and thin slices of the bone.1

Ibirania lived in a dry, inland environment, and its small size may have been an adaptation to scarce resources, not island life like other dwarf sauropods.1

It belonged to a group called Saltasaurinae, which includes some of the smallest titanosaurs.1 2

ຄຳຖາມທີ່ຖືກຖາມຫຼາຍທີ່ສຸດກ່ຽວກັບ Ibirania

?How big was Ibirania?

About 5.7 metres (18.7 feet) long, making it one of the smallest sauropods ever found.1 2

?What did Ibirania eat?

It was a plant-eater. Its name means 'tree wanderer,' which hints that it browsed on trees and shrubs.1

?Did Ibirania have feathers?

No, it did not. Ibirania was a sauropod, and sauropods had scaly skin, not feathers.1

?Why was Ibirania so small?

Scientists think its small size was an adaptation to living in a dry, inland environment with scarce resources, not because it lived on an island.1
