Dinosaurs and humans coexisted:  Positive proof!

At left are footprints of a smallish dinosaur, overlain by the footprints of a human.  We can only imagine whether the dinosaur or human saw each other, but clearly the imprints were left in a short period of time, with the human coming slightly later.  Some of the dinosaur footprints also include the imprint of their tails dragging behind them
This is the same image with tracings around the the footprints to enhance the image.  The human footprints are clearly those of a biped.  It is less clear whether the three-toed dinosaurs were bidepdal or not, given the large number of imprints, but our best reconstruction suggest they were.  Click here for the reconstruction.
