didn't realize such things were believed in 1915.

A web search for "Eogene" turns up papers as late as the '30s.

I've never heard of these before, and can't seem to find a history of
either term on the web. Are these older names for certain units (Early
Cretaceous, Paleocene) or do they reflect erroneous ideas about
correlated strata?
