Description
Enrolled Fossil Trilobite – Reedops maurulus
Devonian Period (~393–383 million years ago)
Found in the Anti-Atlas Mountains, Morocco
Taxonomic Classification:
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Trilobita
- Order: Phacopida
- Suborder: Phacopina
- Superfamily: Acastoidea
- Family: Acastidae
- Genus: Reedops
- Species: Reedops maurulus
- Originally described by Richter & Richter in 1923
Geological Context:
- Age: Middle Devonian
- Stage: Eifelian to early Givetian
- Location: Near Alnif or Erfoud, Anti-Atlas region, southeastern Morocco
- Formation: Lower to mid-Devonian marine shale and limestone beds
- Depositional Environment: Shallow marine shelf with low oxygen zones, likely silty and calcareous muds accumulating in warm epicontinental seas
Morphology and Diagnostic Features:
- Reedops maurulus is known for its distinctive globular cephalon (head), finely detailed compound eyes, and enrolled defensive posture, which this specimen perfectly displays
- Enrolled specimens are particularly sought after, showing how trilobites protected themselves from predators
- It features well-developed pleural lobes, axial lobes, and clearly segmented thoracic rings
- The surface may show fine tubercles and sculpture, especially on the glabella (central lobe of the head)
- Known for excellent preservation in Moroccan limestone, many Reedops specimens display exceptional 3D detail
Palaeobiological Significance:
- Trilobites such as Reedops were benthic (bottom-dwelling) detritivores or scavengers
- Their enrolment behaviour represents an evolutionary response to increasing predation in marine ecosystems
- The genus Reedops is often used for studies in trilobite visual systems due to its highly developed schizochroal eyes
Specimen Details:
- 100% genuine specimen of Reedops maurulus, expertly cleaned and preserved
- Collected from Devonian strata in Morocco, a globally recognised hotspot for trilobite fossils
- Presented in its fully enrolled defensive posture, showcasing iconic trilobite behaviour
- Scale rule / cube = 1cm – see photos for exact sizing
- This is the actual specimen you will receive – no stock photography
- Comes complete with a Certificate of Authenticity
Summary:
This Reedops maurulus trilobite is an excellent enrolled specimen from the Devonian seas of what is now Morocco. With its finely detailed features, evolutionary significance, and iconic posture, it makes a fascinating display fossil for collectors, educators, or anyone with an interest in ancient marine life. A classic Devonian fossil from one of the world’s richest palaeontological regions.
