There is no such thing. The idea of humans living at the same time as dinosaurs seems to have been propagated by the B-movies of the 1950s and 1960s in which dinosaurs attacked humans. In reality, mammals did evolve about the same time as the dinosaurs, but the mammals were not human-like. The dinosaurs died out about 65 million years ago; the first hominids appeared about three to four million years ago; Homo sapiens sapiens (or modern humans) did not appear until about 90,000 years ago.
