#Carboniferous #Earth Time of Great Coal Swamps. By the Late Carboniferous the continents that make up modern North America and Europe had collided with the southern continents of Gondwana to form the western half of Pangea. Ice covered much of the southern hemisphere and vast coal swamps formed along the equator.
Early humans and sabre-tooths co-existed 300,000 years ago - Scientists of the Lower Saxony Heritage Authority and of the University of Tübingen excavating at the Schöningen open-cast coal mine in north-central Germany have discovered the remains of a sabre-toothed cat preserved in a layer some 300,000 years old – the same stratum in which wooden spears were found, indicating that early humans also inhabited the area, which at that time was the bank of a shallow lake.
