3 rd Swiss Geoscience Meeting, Zürich, 2005 Mind the “Middle Jurassic ” gap Bone versus track record in dinosaurs
Up to now studies on vicariance biogeography or cladistic biogeography of dinosaurs have been performed with body fossils only. In the Triassic and Early Jurassic these methods have produced rather coherent patterns, probably due to the existence of Pangaea. They show a large cosmopolitan community...

| Summary: | Up to now studies on vicariance biogeography or cladistic biogeography of dinosaurs have been performed with body fossils only. In the Triassic and Early Jurassic these methods have produced rather coherent patterns, probably due to the existence of Pangaea. They show a large cosmopolitan community of herrerasaurids, coelophysoids, prosauropods and basal ornitischians (Holtz et al. 2004). The fossil record of body and trace fossils of dinosaurs in the Middle Jurassic consists of rather limited information. Today more than hundred locations are known to contain either trace or body fossils. Although scattered, they occur on all continents except on Antarctica. The best record |
