Fossil trilobite of the genus Austerops sp. from the Middle Devonian, Djebel Issoumour, Morocco, on original matrix, dimensions 93 × 79 × 40 mm, weight 334 g.
Description from the seller
Trilobite belongs to the genus Austerops, one of the most well-known representatives of the order Phacopida, which lived about 390 million years ago during the Middle Devonian. The specimen comes from the famous fossiliferous formations of Djebel Issoumour, located near Alnif in the southeastern region of Morocco.
During that period, this area was covered by the warm waters of the Rheic Ocean, with ideal conditions for fossilization: fine sediments, low oxygen concentrations, and rapid burial.
Austerops is distinguished by its robust and slightly granular exoskeleton, broad and rounded glabella, and well-developed schizocral eyes composed of individually arranged lenses, which provided an extremely precise vision.
The body structure, with a segmented thorax and well-defined pygidium, suggests an active benthic lifestyle on the seabed.
The specimen is complete and beautifully preserved, with morphological details such as the thoracic ridges, the granulation of the cuticle, and the cephalic shape clearly visible.
The natural coloration varies between brown, reddish tones, and lighter shades, highlighted by professional preparation that has preserved the original surface of the fossil.
Age: Middle Devonian (~390 million years ago)
Genus: Austerops sp.
Order: Phacopida
Origin: Djebel Issoumour, Alnif, Morocco
Measurement of the trilobite (without matrix): 62 mm.
Condition: Authentic specimen on original matrix.
