Spectacular graptolites with extraordinary preservation!!! - Fossilised animal - Clononograptus rigidus (Hall, 1858) - 22 cm - 17 cm

Spectacular plate with a Clononograptus rigidus specimen. There are also other Clonograptus specimens partially preserved and other types of graptolites. Plate with a very well fossilized Clononograptus. The Clononograptus is spectacular, it is very complete and shows extraordinary preservation. Specimens of this quality are extremely rare. The contrast of the fossils with the matrix is spectacular. The extraordinary preservation of the fossils allows viewing in great detail the delicate structures of the different graptolites. The preparation of the specimen was very laborious, preserving the finest details. A specimen worthy of a Museum.

Graptolites are an extinct class of the phylum Hemichordata. They are fossils of colonial animals that emerged at the end of the Cambrian and disappeared at the beginning of the Carboniferous. Graptolites are small animals that lived in groups or colonies. Some colonies formed branched shapes. The different types of graptolite colonies had branches with different forms. They can be straight, curved, or even spiral in form.
The fossil beds of the Fezouata Formation, near the Moroccan town of Zagora, are providing a rich and varied record of fossils with extraordinary preservation, so much so that soft parts or soft-bodied animals are frequently preserved. This type of preservation is similar, though later in time, to that of the famous Burgess Shale (Canada).

These are fossils dating between 480 and 472 million years ago. Back then, Morocco was an ocean and lay near the South Pole.
