AI-assisted summary
Description from the seller
Spectacular plate with more than 25 complete specimens of Rhopalocystis havliceki, a primitive and enigmatic echinoderm that lived during the Ordovician of the eocrinoid group. This species is the largest of the Ordovician Rhopalocystis from Zagora. Eocrinoids were a primitive group of echinoderms, possibly related to crinoids.
The slab contains at least 25 complete specimens and remains of many others. Accumulations like this are very rare. 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 Rhopalocystis havliceki. There is a plate and a counterplate. A specimen worthy of a museum.
Plate 1: 2010 g; 39 x 16 x 1.7 cm
Plate 2: 776; 36.5 x 15.5 x 1
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.
