Minkin site photos


Attenosaurus subulensis, the footprint of a top predator, and raindrop impressions, both 313 million years old, much older than dinosaurs. Raindrop impressions are very rare at the site, because the muddy tidal flat rarely dried out. The maker of A. subulensis looked a bit like an alligator, and far outweighed any other land animals found in the area.

New book about the site, Footprints in Stone:
