The ontogeny of the dwarf sauropod Europasaurus holgeri and the phylogeny of basal Macronaria (Saurischia, Sauropoda)
Zusammenfassung der Projektergebnisse
Europasaurus holgeri is a remarkable island dwarf sauropod dinosaur, one of the most spectacular discoveries in German paleontology in Germany in the last 50 years. The project being reported on here was aimed at the initial morphological description of this exceptional material which was completed despite the change in principal investigators during the middle of the project. Major results include detailed descriptions of cranial and postcranial axial skeletal morphology, the great ontogenetic change observable in this material, the surprising recognition of the existence of a small and a large morph (both being dwarfed), and new and greatly refined phylogenetic analysis of Europasaurus and macronarian sauropods in general. Additional research projects were spawned by this DFG project, most notably a major project funded by the VW foundation. Thus Europasaurus, the "pocket sauropod", is rapidly becoming a classic in the study of sauropod dinosaurs, the largest creatures that ever lived on land.
