The three paleontologists exposed several meters long tracks. They found that a series of round footprints belonged to a sauropod herd. The eleven long-necked lizards of different sizes moved side by side at a steady pace through the silt. The hind feet were on average 57 centimeters long and 46 centimeters wide, the fore feet a little smaller. The animals were related to the largest representatives of the gigantic sauropods, such as Brachiosaurus and Diplodocus. However, the researchers could not determine the nature of the prints alone.
In addition, there were 14 footprints of a relatively large two-legged dinosaur at the site. From the threefold form of the imprints, the researchers concluded that it was an ornithopod. To this group counted for example the well-known Iguanodon and the so-called duck bill dinosaurs, the Hadrosaurier. Many researchers also call the ornithopods "Cows of the Earth's Middle Ages". Schulp and his colleagues now hope to find in the previously barely studied region also bones from the Jura, which could give them information about the distribution of various dinosaur groups.Anne Schulp (Natuurhistorisch Museum, Maastricht, Netherlands) et al .: Plos ONE, vol. 3, no. 5, e2243 Ute Kehse advertisement
