Europasaurus

名字的意思： “Europe lizard”1

吃：植物長脖子恐龍侏羅紀晚期

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

酷東西

趣味知識

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

關於 Europasaurus 最常被問的問題

?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

迷思破解王

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

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

發現: The first fossils were found in 1998 by Holger Lüdtke in a quarry in Germany. After more bones were found, the species was named Europasaurus holgeri in 2006 by Sander and colleagues.1
仍有爭議: Scientists are not sure exactly why Europasaurus became so small, but they think it was because it lived on an island with limited food.2
