Dinosaur footprints preserved at the Langenberg Quarry display a possible reason for the extinction of Europasaurus, and potentially other insular dwarfs present on the islands of the region.
The footprints are located 5 m (16 ft) above the deposit of Europasaurus individuals, which shows that at least 35,000 years after that deposit there was a drop in sea level which allowed for a faunal overturn.
The inhabiting theropods of the island, that coexisted with Europasaurus, would have been about 4 m (13 ft), but the theropods that arrived over the land bridge preserve footprints 
up to 54 cm (21 in), which indicates a body size between 7 and 8 m (23 and 26 ft) if reconstructed as an allosaurian.
It was suggested by the describers of these tracks (Jens Lallensack and colleagues), that these theropod taxa likely made the specialized dwarf fauna extinct, and the bed from which the footprints originated (Langenberg bed 92) is probably the youngest in which Europasaurus is present.
