AI-assisted summary

Description from the seller

Spectacular complete specimen of Nimchacystis agterbosi, a primitive and enigmatic echinoderm that lived during the Ordovician. The specimen is perfectly preserved, showing the body, the appendage, and the distele. The animal Nimchacystis is a primitive echinoderm from the group of the soluta. Nimchacystis had an oval body, a lateral feeding appendage, and a twisted and flattened dististele. These animals are interpreted as active epibenthic feeders that consume detritus and use their distíteles to crawl over soft substrates. There is plate and counterplate.

The plates contain one complete specimen. Specimens with this level of preservation are extremely rare. The contrast between the fossils and the matrix is spectacular. The extraordinary preservation of the fossils allows for detailed observation of the delicate structures of Nimchacystis. The preparation of the specimens has been extremely laborious, as the fossils are very delicate. A specimen worthy of a museum.

Rolled Nimchacystis dimensions: 40 x 25 mm.

Plate: 799 g; 16.5 x 13 x 3 cm
Plaque: 915 g; 14 x 12 x 4 cm


Plastic supports included.

The Fezouata formation sites, near the Moroccan city of Zagora, are providing a rich and diverse record of fossils with extraordinary preservation, often including soft tissues or soft-bodied animals. 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.
