1. MARSUPIALS II: Zoogeography & Diversity EEOB 625 21 January 2004

2. Zoogeography of Metatherians Place of origin: North America or South America? How do we decide? Possible routes of dispersal for descendants of Didelphidae: northern or southern routes evidence from fossils in Antarctica Isolation & radiation of S. American marsupials 130 fossil genera, including Borhyaena & Thylacosmilus What about other forms (genera an families) ( p. 75-80 )

5. Zoogeography of Metatherians II Evolution and Radiation of metatherians in Australia Reached Australia before eutherians Major radiation of large metatherians (Thylacoleonidae & Diprotodontidae) until the Pleistocene & then extinction. Why Competition with eutherians or arrival Aboriginies?
