Ancient Acrocanthosaurus footprint fossilized in beige stone underwater.
A view down of an Acrocanthosaurus footprint in stone underwater. It is in the middle, and the water is clear. The lake bed is beige stone, with some darker areas on the bottom left. The footprint has three short vertical lines in the stone that are spread out, and then one curved horizontal line in the middle under the three. The print is dark in the beige stone. There is a reflection in the water on the bottom right. It is a line of light. There are also two white circles of light with rays in the middle, slightly to the left. One is above the other.
