Re: Ice Sheets Caused Massive Sea Level Change During Late Cretaceous



Thanks Richard, but I should have been a little clearer about what I was
questioning....I was actually wondering about the dropstones and the
plesiosaur calving grounds that Christopher Collinson mentioned.  There are
some reports of dropstones from the Great Artesian Basin in some of the
slightly older (20 - 30 years) geological literature, and there have been
rumours of juvenile plesiosaurs from South Australia in the last couple of
years.  I was wondering whether there has been any discussion of the
dropstones in more recent literature, and if Ben Kear has published his
research into the 'baby' plesiosaurs.

Cheers
Colin
