Europasaurus was a tiny sauropod dinosaur that lived on an island in what is now Germany. It was a dwarf, much smaller than its giant relatives like Brachiosaurus. Scientists think it shrank because food was limited on its island home.2 1

Datu dibertigarriak

Europasaurus is one of the smallest known sauropods, only about as long as a car.1

It lived during the Late Jurassic, about 154 to 151 million years ago.1

Fossils of at least 11 individuals were found together, suggesting they lived in herds.2 1

The first fossil was a single tooth found by a private collector named Holger Lüdtke in 1998.1

Bone studies show that Europasaurus grew more slowly than its giant relatives, a sign of island dwarfism.2

About one third of the Europasaurus bones found have tooth marks, probably from fish or crocodile-like scavengers.1

Young Europasaurus had well-developed inner ears, meaning they could probably hear well and may have stayed close to adults for protection.1

zure galderak

Europasaurus: gehien egindako galderak

?How big was Europasaurus?

About 5.7 to 6.2 metres long, weighing 750 to 2,100 kilograms as an adult. That is roughly as long as a car.1 3

?Why was Europasaurus so small?

It was a dwarf species due to insular dwarfism, meaning it shrank because it lived on an island with limited food. Bone studies show it grew more slowly than its giant relatives.2 1

?What did Europasaurus eat?

It was herbivorous, meaning it ate plants. Conifer cones and twigs from araucarian trees (like modern monkey puzzle trees) have been found at its fossil site.3 1

?Did Europasaurus live in herds?

Yes, fossils of at least 11 individuals were found together, suggesting they lived in groups. Scientists think a herd might have drowned while crossing a tidal zone.1

?When did Europasaurus live?

It lived during the Late Jurassic Period, about 154 to 151 million years ago.1 3

?Where was Europasaurus found?

Its fossils were found in a quarry at Langenberg Mountain in northern Germany. It lived on an island in the Lower Saxony basin.1

Mito-hauslea

Mitoa: Europasaurus was just a baby of a larger sauropod.

Egia: Bone histology shows that the fossils are from adults, not juveniles. Europasaurus was a true dwarf species.2 1
