Graptolites are an extinct class of the Phylum Hemichordata. They are fossils of colonial animals that appeared at the end of the Cambrian and went extinct at the beginning of the Carboniferous. Graptolites are small animals that lived in groups or colonies. Some colonies formed branching shapes. The different types of graptolite colonies had branches with various shapes. They could be straight, curved, or even spiral.
The deposits of the Fezouata formation, near the Moroccan city of Zagora, are providing a rich and diverse record of fossils with extraordinary preservation, up to soft tissues or soft-bodied animals being recorded fairly frequently. This type of preservation is similar, although later in time, to that of the famous Burgess Shale site (Canada).

These are fossils dating from between 480 and 472 million years ago. At that time, Morocco was an ocean and was located over the South Pole.
