What is the difference between cro-magnons and Homo sapiens sapiens?

Cro-Magnon is an informal word once used to refer to people who lived alongside Neanderthals toward the end of the last ice age (around 35,000-10,000 years ago). The name came about because in 1868 parts of five skeletons were found in a cave by that name located in the Dordogne Valley of France.

Recently it has been considered that the physical dimensions of 'Cro-Magnon' are not sufficiently different enough from modern humans to warrant a separate designation. Essentially, we're a bunch of Cro-Magnons.

The differences between these early modern humans and us are slight and may be attributed to a different life style (hunting and gathering verses TV watching and video game playing). Some, though, insist there is a physical difference that indicates the Cro-Magnons are a really different people from us.

There is not enough bones to look at. There is not, at present (and maybe never) enough of a sample size to settle the argument.
