The similarity between other later east coast US and European Stone Age stone tool technologies has been noted before.
But all the US European-style tools, unearthed before the discovery or dating of the recently found or dated US east coast sites, were from around 15,000 years ago - long after Stone Age Europeans (the Solutrean cultures of France and Iberia) had ceased making such artefacts.
Most archaeologists had therefore rejected any possibility of a connection.
But the newly-discovered and recently-dated early Maryland and other US east coast Stone Age tools are from between 26,000 and 19,000 years ago - and are therefore contemporary with the virtually identical western European material.
Dating as an institution is a relatively recent phenomenon which has mainly emerged in the last few centuries.
