Europasaurus holgeri Variant:Primed characterized by very largeEuropasaurus holgeri is a species of dwarf sauropod dinosaur that lived during the Late Jurassic, specifically in the Kimmeridgian and Tithonian, approximately 154 150 million years ago. Dwelling in what is now Germany during the Late Jurassic, unlike its giant sauropod relatives, Europasaurus experienced an evolutionary phenomenon known as island dwarfism, where a species' body size decreases due to resource limitations on an island or isolated area.
