On this
large slab of rock there are three body resting traces that
are followed by three separate trackways. All of the trackways
head in the same direction. These trace fossils are the world's
earliest evidence of herding behaviour in vertebrate animals,
made long before dinosaurs roamed the Earth. The trackways were
all made by Seymouria, a primitive reptile. The cracks you see
in the rock were made as the sun baked the muds. |
