Art, I finally got around to checking some things. Thre is plenty of
Oligocene strata and it is found in drill cores of the DSDP. See "Brian E.
Tcholke, "Tertiary Paleoocianography of hte Western North Atlantic Ocean,"
in The Geology of North America Vol. M, "The Western North Atlantic Region",
1986
There is oligocene sediment beyond Bermuda and there is over 2000 meters of
Oligocene lower miocene shown in that article also.
If you ever find the reference, I would still like to look at it but I don't
think the author was correct.
