This shoe-print fossil was discovered in a seam of coal in Nevada. The coal is aged to be over 15 million years old!! And lest you think that this is the fossil of some kind of animal whose shape merely resembles a modern shoe, close-up examination of the fossil reveals the traces of a double line of sewed stitches around the perimeter of the shape are clearly visible. The right side of the heel appears to be more worn down than the left.
There are multiple stories that go with this “finding” which takes from the credibilty of the story.
