When they re-analyzed a skeleton that was discovered in Trossingen in 1922, consisting mainly of the rear of the body, Regalado Fernandez and Werneburg established that many of the bones were not the same as a typical Plateosaurus. For instance, the partial skeleton displayed, among other derived characters, broader and more strongly-built hips with fused sacral vertebrae as well as unusually large and robust long bones - both features implied locomotion on four legs. This is unlike the Plateosauridae, which although resembling the long-necked sauropods from the Jura region likely moved on only two legs.

Following in-depth comparison of all anatomical characteristics, the scientists recategorized the partial skeleton from Trossingen in the dinosaur tree of life and established that they had discovered a previously unknown species and genus. It is highly probable that Tuebingosaurus maierfritzorum was a quadruped and accordingly far more closely related to the later large sauropods such as Brachiosaurus or Diplodocus than with the Plateosauridae. The surrounding sedimentary rock and the preservation of the bones indicate that this Tuebingosaurus had sunk into a swamp and died. The bones on the left side of the body were probably on the surface and exposed to the elements for several years.

-Its genus name, Tuebingosaurus, is a homage to our beautiful university city and its inhabitants,- says Werneburg. The species name maierfritzorum is a tribute to the two German zoologists, Professor Wolfgang Maier from and Professor Uwe Fritz from Senckenberg Natural History Collections Dresden. The new species has now been described in the latest edition of the Senckenberg Natural Science Society’s journal Vertebrate Zoology, which also pays tribute to Wolfgang Maier on his 80th birthday.

In sum, the scientists have been able to show by their project that the early European dinosaurs were far more diverse than previously thought. The individual parts of the skeleton of Tuebingosaurus maierfritzorum, which until now have been stored separately, are now reunited and can be seen in two large display cabinets. Besides thousands of other treasures, there are two complete Plateosaurus skeletons from Trossingen, partial skeletons of two sauropods and one stegosaur from Tanzania to wonder at in Tübingen’s paleontological collection.
