Schleitheimia (named after the type locality of Schleitheim), is an extinct genus of sauropodiform sauropodomorph dinosaur, which was closely related to Sarahsaurus,[1] from the Gruhalde Member of Klettgau Formation of Switzerland. The type species, Schleitheimia schultzi was formally described in 2020.[1]
Discovery and naming
The type material was collected between 1952 to 1954 by E. Schutz. They were donated to the University of Zürich in 1955. In 1986, most of the material was described by Peter Galton, who referred them all to the species Plateosaurus engelhardti.
In 2020, Oliver Rauhut, Femke Holwerda and Heinz Furrer redescribed most of Schutz's remains, as well as some remains in the collections of the Museum zu Allerheiligen in Schaffhausen and new remains from a recent excavation led by one of us Holwerda. They found that these remains represented a new genus and species, which they named Schleitheimia schultzi, honoring the type locality and the discoverer of the type remains.
The holotype, PIMUZ A/III 50, was found in a layer of the Klettgau Formation dating from the Norian. It consists of a partial right ilium or shinbone. Several other bones from the general locality were designated as paratypes. Because they are consistent in morphology, the describers referred all of the to the same taxon, if not the same individual.[1]
Description
Schleitheimia's holotype shows a unique combination of traits that in themselves are not unique. There is a broad, rounded ridge on the iliac blade that ends in a large, rounded expansion on the ilium. The fourth tronchanter of the ilium is very robust. The crista tibiofibularis of the femur is broad and that no posteriorly facing shelf is present lateral to the crista.[1]
