3213 BCE to 3070 BCE
Land transport vehicles in Sumer include sledges and the earliest known wheeled carts, which appear around 3150, representing the first use of the wheel for transportation.
A clay tablet from the period 3200—3100 (found by twentieth century archaeologists in the courtyard of the Eanna Temple in Uruk) contains a pictograph of a wheeled cart.
