Description
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
