RARE Conocoryphe heberti Trilobite Fossil (Partial) – Middle Cambrian – Murero Formation – Spain – Certified Authentic

RARE Conocoryphe heberti Trilobite Fossil (Partial)

Middle Cambrian – Murero Formation – Rambla de Valdemiedes, Mureri, Zaragoza
Province, Spain

This is a genuine partial trilobite fossil of Conocoryphe heberti, from the world-renowned Murero Formation in Rambla de Valdemiedes, near Mureri in northeastern Spain. A significant site in European palaeontology, the Murero region is famed for producing some of the most scientifically studied Cambrian trilobites

Geological & Stratigraphic Details

• Locality: Rambla de Valdemiedes, near Murero, Zaragoza Province, Spain
• Formation: Murero Formation
• Geological Period: Middle Cambrian (~510–500 million years ago)
• Stage: Wuliuan Stage (formerly Languedocian)
• Biozone: Typically found in the Eccaparadoxides Zone
• Depositional Environment:
• Shallow to moderately deep marine setting
• Fine siliciclastic deposits—shales, siltstones, and mudstones
• Deposited under low-energy, oxygen-poor conditions

Fossil Type & Morphology

• Type: Trilobite (partial – often cranidium or thoracic fragments)
• Species: Conocoryphe heberti
• Order: Ptychopariida
• Superfamily: Conocoryphoidea
• Family: Conocoryphidae
• Genus: Conocoryphe
• Formally described by: Barrande, 1848

Morphological Features (if identifiable in the specimen):

• Smooth cephalon with a wide, flat glabella
• Lack of eyes – Conocoryphe heberti is completely eyeless (atheloptic)
• Simple thorax with consistent segment structure
• Rounded pygidium, relatively featureless

Scientific & Historical Importance

• Conocoryphe heberti is one of the most classic and widely cited eyeless trilobites of the Middle Cambrian
• Often used in biostratigraphic zonation across the European Cambrian system
• Valued for its palaeoecological significance, being part of the soft-bottom marine community
• Frequently found alongside paradoxidid trilobites in the Murero Lagerstätte
