Calvarius

Izina risobanura: “The name comes from the Serrat del Calvari hill and the Catalan word 'calvari' meaning 'suffering', referring to its closeness to the extinction event.”1

Calvarius was a small, speedy plant-eating dinosaur that lived near the very end of the Age of Dinosaurs. It was one of the last dinosaurs to walk on Earth before the big asteroid hit.2

Utuntu dushimishije

1

Calvarius is known from just one foot bone, a left metatarsal IV, which was about 15 centimeters long.2

2

It was probably a fast runner. Its long foot bone and light build suggest it could sprint quickly, unlike most other styracostern dinosaurs.1

3

Calvarius lived on a large island called Ibero-Armorica, which is now northern Spain and southern France. On islands, animals sometimes evolve to be smaller because food is limited.2

4

It was one of the last dinosaurs ever. Its fossils were found just 25 meters below the layer that marks the asteroid impact that killed the non-bird dinosaurs.1

5

The fossil was discovered in 2019 by paleontologists from the Institut Català de Paleontologia Miquel Crusafont and the Museu de la Conca Dellà.2

6

Calvarius is the smallest known styracostern dinosaur. Some of its relatives grew over 10 meters long, but Calvarius was less than 2 meters.2

Byakozwe na AIIshusho ya Calvarius yakozwe na AI
Ishusho yakozwe na AI yerekana uko Calvarius ishobora kuba yari isa, yakozwe na mudasobwa hashingiwe ku byo abahanga bazi. Ni ugukeka gusa: inyamaswa nyayo ishobora kuba yari isa ukundi, kandi nta muntu uzi amabara yayo nyayo.

Ibibazo bibazwa cyane kuri Calvarius

?How big was Calvarius?

Calvarius was no more than 2 metres (6.6 feet) long, making it one of the smallest known styracostern dinosaurs.2

?What did Calvarius eat?

Calvarius was a plant-eater. It was an ornithopod, a group of herbivorous dinosaurs.2

Scientists are not sure exactly how big Calvarius was because only one foot bone has been found. They estimate it was less than 2 meters long, but it could have been different.2
