Here is a very unique trace fossil. This is a fine slab of trilobite trackways from the Devonian of Morocco. There are a number of trackways present and also some other trace fossils. The trackways are clearly defined. You can easily see how the legs of the trilobite pushed up ridges of mud as the arthropod crawled along the bottom of the sea. This is an extremely interesting plate of trilobite trackways from this new find in Morocco.
