Europasaurus, a dwarf sauropod dinosaur, was relatively small compared to its sauropod relatives. It reached lengths of 6.6 to 19.7 feet (2 to 6 meters), stood about 3.3 to 6.6 feet (1 to 2 meters) tall, and likely weighed around 1 to 2 tons. This size reduction was likely due to island dwarfism during the Late Jurassic period.
