How cold was antarctica in the mid-late
Triassic? Lystrosaurs were found there from the (late Permian???),..no? And
dinosaurs were found that must have at least migrated through there also
(Jurrassic-Cretaceous?). Could someone clarify these time frames?
What sparked me off was a statement by
Wellnhofer in his Pterosaur book (pg 9 under diagram of fossil
distribution)..."The distribution of fossil finds indicates that pterosaurs
once lived on all continents except Antarctica." Is this just poor phrasing
due to translation probs, or is he indicating that (statistically), there is
indication that there really were no Pterosaurs in Antarctica? Was it just too
cold for them, even at that earlier time? The earlier pterosaur finds do seem to
be grouped around the equatorial region (for the Triassic)....Just how cold was
it?
