Whats the difference between Oldowan and Acheulean tools?

Question

I know Oldowan tools are older than Acheulean and werent first used by Homo sapiens. But im having a hard time distinguishing them.

Answer 1

Oldowan tools are associated with Homo habilis  (Some sites containing oldowan tools and homo habilis also contain the remains of robust Australopithecines, but most people don't think they made or used the tools).  They are very simple - they look like a round cobble with the top knocked off.

Acheulean tools were made by Homo erectus.  They are much more complex, with many pieces removed to make the final product.  It looks like a hand axe, with a pointy top and a wide, flat base.  We jokingly refer to it as the "Swiss army rock" because it's pretty much an all-purpose tool.  It's good for smashing or cutting.

Answer 2

the workmanship...the implementation,..and the social structures..otherwise, not too much.  The simplicity for the oldowans was ..is.. about as good and reliable method of determination as your gonna get. We all wish for some uniquely defining characteristics.., and we all settle for what we get.

Answer 3

Oh lithics identification just takes a lot of practice.
