The steppe bison is an extinct species that was once found in a band of the world's northern latitudes, including the United Kingdom, Europe, Russia and Canada.
They went extinct roughly 5400 years ago.
Dating back to the Ice Age, these were found in Siberia in summer 2020. They measure ~6.5-7.5" long.
