Was there humans alive during devonian era?

The were definitely no humans in the Devonian Period. The Devonian Period lasted from 416 to 359 million years ago. Homo sapien or modern human did not evolve until 200 thousand years ago in the Pleistocene Epoch of the Quaternary Period, some 358.8 million years after the Devonian ended. They are the only living example of the genus Homo in which the earliest members evolved 2.8 million years ago during the Pliocene Epoch of the Neogene Period. Modern humans are also in the family Hominidae which also includes all the great apes and some lesser apes. The earliest examples of Hominids date back to about 20 million years ago in the Miocene Epoch of the Neogene Period. In turn we belong to the order of primates which were thought to have evolved close to the end of the Cretaceous Period or the start of the Paleogene Period about 66 to 65 million years ago. Even the family Mammalia of which we belong did not evolve until the late Triassic Period about 200 million years ago. This was still some 159 million years after the end of the Devonian. Mammals evolved from the Reptilian Synapsida Subclass. They themselves did not evolve until the Carboniferous Period about 309 million years ago, some 50 million years after the Devonian. There were not even reptiles during the Devonian. Reptiles were thought to have evolved from amphibians during the Carboniferous Period about 320 million years ago. During the Devonian our only ancestors alive were the amphibians.

Devonian to cretaceous is the the geological age of ammonoids They first appeared during the Devonian Period (approximately 410 million years ago). They almost died out at the end of the Permian Period (251 million years ago), and again at the end of the Triassic Period (205 million years ago). They finally became extinct at the end of the Cretaceous Period (65 million years ago), perhaps as a result of a lowering of ocean levels.
