Chelichnus ✝
| Description | Chelichnus is an ichnogenus of Permian tetrapod footprint. The name means tortoise traces, because the shape of the prints was originally mistakely thought to be produced by a tortoise. This is now known to be incorrect, as tortoises did not evolve until much later. It was first found in Corncockle Quarry in Dumfries, Scotland.
