Just back from a small Greek island a few miles from Turkey, where we saw
a large oak tree, with leathery evergreen leaves about 9cm long and 3 cm
wide, with toothed edges.

But the most striking thing was the acorns - almost 5cm long, peering out
of a thick shaggy cup 5.5cm diameter.

Best identification so far is Quercus calliprenos. But I think the scales
on the cup of that one are turned out at the tip, whereas the ones on
mine are laid flat.

Could it be from Quercus macrocarpa, the Burr (or Bur) Oak?

No - the leaves are more linear, and are toothed rather than lobed.
While the acorn size s right, the cup is more massive.
