The Laurentide Ice Sheet covers most of present-day Canada and parts of the northern United States in light blue, the Cordilleran Ice Sheet covers the Pacific Northwest in teal, and the Greenland Ice Sheet is marked in purple. Modern international and state or provincial boundaries are outlined for reference. — Pleistocene Epoch Ice sheets during the Wisconsin glacial episode penetrated deep into North America.

Fossil remains of Homo antecessor have been discovered in the Sierra de Atapuerca region of northern Spain, specifically within the Gran Dolina cave site.12

Regarding the timing of their existence, these remains have been dated to approximately 800,000 years ago. Some researchers have also proposed that H. antecessor may have been present in Eritrea in deposits dating to about one million years ago, though the classification and evolutionary placement of these fossils remain subjects of scientific debate among paleoanthropologists.12
