Amazing plate with the tracks of 4 different trilobite tracks crossing the plate, as well as 2 different Gastropod (snails) that left their impressions on the prehistoric seafloor with each stride, the track on the top shows the impression of the long thin shell perfectly! There is also a worm burrow on the bottom of the plate.

This is the only plate I have ever seen from Morocco with these Gastropod (Fustiglyphus) tracks, they have only been described from the Ordovician of the USA. The similarities are too obvious to ignore.

Found often near the fossils of the trilobite Asaphellus aff. fezouataensis, it is thought these trace and burrows are from that trilobite.


These ichnofossils (trace fossils) show a snapshot of life 445 million years ago. Rusophycus (Trilobite resting nest), Cruziana (trackways furrowing/emerging), & Diplichnites (walking/striding) ichnofossils - trace fossils - are all present on the various plates. Even some non-trilobite tracks on a couple - worms and even other arthropods.
