300 million year old wheel

Rather interesting find of a wheel some miners found that would have to have been 300 million years old to have been at that layer of earth. Its only an imprint tho as the wheel itself would have had to have disintegrated by now. I’m curious based on its size if its a wheel people actually used for pulling carts or if its perhaps a Dhammacakka symbol from one of the ancient Buddhas such as Lord Kassapa Buddha’s time.
