> Diplodocids are known from deposits present in the U.S.A., Europe, South America, and Africa. According to the available evidence, the oldest diplodocid sauropod dates back to the Oxfordian of Europe, whereas the most recent ones are from the lowermost Cretaceous of South America and Africa.
It als says that "The European diplodocid fossil record is scarce and fragmentary," but that still sounds like evidence for Diplodocus in Europe, doesn't it?
