File-Picture taken in August 2017 show linear clusters of trilobites (arthropods) on the surface of the rock slab. These fossils come the Fezouata Shale in Morocco (near Zagora). Their age is 480 million years. The trilobites are all oriented towards the same direction. The head part has a long spine in the front. There are also two lateral spines along the animal's body.
