Thanks..... The graphic certainly shows the highstand during the Late
Cretaceous... now I need to convert depth into areal coverage...
I might take this opportunity to remind everyone that the cited Hallam
article:
Hallam, A. 1989. The case for sea-level change as a dominant
causal factor in mass extinctions of marine invertebrates. /Phil. Trans.
Royal Soc. B/ 325, 437-455.
and many others are available on-line (and free) from the Royal Society
website through mid-November:

Click on the "archives" at the bottom of the page.
