Europasaurus

“European lizard”
SauropodomorphherbivoreLate Jurassic

A sauropod shrunk to the size of a cow by life on a small island

Overview

Europasaurus is a basal macronarian sauropod, a form of quadrupedal herbivorous dinosaur. It lived during the Late Jurassic of northern Germany, and has been identified as an example of insular dwarfism resulting from the isolation of a sauropod population on an island within the Lower Saxony basin.

Why it matters

  • Adult bones from a Lower Saxony quarry show full-grown animals only 6 metres long.
  • Insular dwarfism: its ancestors shrank over generations on a Jurassic island with little food.
  • Named in 2006; hundreds of bones from at least a dozen individuals are known.
