Worm
Early Ordovician (Arenigian)
Upper Fezouata Formation
Zagora, Draa Valley

The Fezouata Formation is a globally significant fossil deposit preserving a wide range of early marine life in fine-grained sediment, including soft-bodied organisms that are rarely preserved elsewhere. Worm fossils from this formation represent early benthic seafloor dwelling animals living in shallow marine environments.
