Hi Michael,

<<I'm not convinced. Crocodiles can pass the sea, and Seymour Island is not
the antarctic continent. We sohuld get more information from the Atlas
Project. For my eyes the maps show separation in late Cretaceous. For me it
sounds very strange if there were feasible land bridges from South America
to Australia in Eocene. If there were a connection: Where are the australian
Eutheria / Xenarthra?>>

The sloth's at Seymour Island along with gondwanatherians and a rhea,
(Eocene).  The presence of monotremes (Monotrematum) in the Paleocene of
Patagonia suggests immigration.  Monotremes are otherwise only known from
Australasia since the Lower Cretaceous.
