Re: No island fossils

I don't think "islands in the sea" are actually the most
productive means of isolation for stimulating evolution.

Caves and mountains represent other types of isolation, though
often do not represent terribly hospitable environments.

Freshwater lakes can be isolation - for fishies.
E.g. the Cichlid fishes of the great lakes.
These would seem to offer relatively good fossil potential.

Glaciation and deserts could also produce isolation.

It is normally the interior - not the exterior of the desert that
is isolated - and again this is not a terribly hospitable environment,
and might not leave too many fossils.
