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.12

Mfundo zosangalatsa

1

Ibirania is one of the smallest sauropods known, only about 5.7 metres (19 feet) long.12

2

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

3

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

4

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

5

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

6

It belonged to a group called Saltasaurinae, which includes some of the smallest titanosaurs.12

Mafunso ofunsidwa kwambiri okhudza Ibirania

?How big was Ibirania?

About 5.7 metres (18.7 feet) long, making it one of the smallest sauropods ever found.12

?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

Ibirania was named in 2022 by Navarro and colleagues based on fossils found on a farm in Ibirá, São Paulo, Brazil. The name means 'little tree wanderer' after the town and its small size.12

Scientists are still studying the tiny parasites found in Ibirania's bones to figure out exactly what they were.1
