Golden Positive/Negative Plate Daguinaspis ambroggii (Hupé & Abadie, 1950) – Souss Lagerstätte, Morocco | PAIS9600 Please see the high-resolution photos for full details: specimen in matrix context, isolated view, and magnified close-ups. Additional images available upon request. OUR GRADING FOR THIS SPECIMEN: 4/5 **** - detail, colour, positive/negative, untouched. Lacking visible pygidium (inside negative part). (Graded using our transparent 5-point system — see seller info for details. This scientifically significant plate from the Lower Cambrian of Morocco features a adult internal and external moulds (AKA positive/negative or part/counterpart) of Daguinaspis ambroggii (Hupé & Abadie, 1950). It exhibits extreme detail from all anatomical characteristics, exception made to the pygidium (not visible, as on the vast majority of Falotaspidids). The specimen comes from the Daguinaspis Zone of the Upper Amouslek Formation, the only horizon in the Tazemmourt Section with Konservat-Lagerstätte-type preservation. Restoration details: All natural specimen, untouched slab after split. Dimensions Trilobite: 3.1 × 1.5 cm Matrix: 10 × 4.3 cm Weight: 171 g Scientific Details Species: Daguinaspis ambroggii (Hupé & Abadie, 1950) Family: Fallotaspididae Order: Redlichiida Class: Trilobita Lithostratigraphy: Upper Amouslek Formation Age: Lower Cambrian (Series 2, Stage 3) – ca. 520–515 million years old Biostratigraphy: Daguinaspis Zone, Issendalenian, from the Souss Fossil Lagerstätte Locality: Tazemmourt Section, Northern slope of the Western Anti-Atlas, Morocco Collection Code: PAIS9600 | Collected: July 2025 Why This Stands Out? • Adult internal and external moulds of Daguinaspis ambroggii, showing well-preserved cranidium with concave pre-glabellar field extending to the eyes and great detail at all anatomical characteristics • Elegant 3D preservation with minimal compression, indicating rapid burial and early diagenetic stabilization • Striking yellow diagenetic coloration, likely due to iron oxide mineralization – enhancing contrast and visual appeal • Freshly collected (July 2025), fully documented provenance (PAIS9600) • From the Tazemmourt Section – type locality of the Souss Lagerstätte, the first Cambrian fossil lagerstätte known from Africa • Museum-grade specimen offered with no reserve price Special notes on Coloration : The specimens exhibit striking yellow hues, likely resulting from mineralization processes in the exoskeleton – possibly involving iron oxides incorporated during diagenesis. These tones enhance the contrast with the warm-toned limestone matrix and highlight the 3D relief of the axial lobe, cephalic structures, and pleurae, adding both aesthetic elegance and taphonomic interest. Additional Notes: Daguinaspis ambroggii was among the earliest defined genera of Cambrian trilobites based on Moroccan material and is restricted to the Western Anti-Atlas. Its occurrences suggest a preference for fine-grained siliciclastic sediments (Geyer, 1990, 1996). The absence of the pygidium - in this case, hidden - is common in fallotaspidids and may reflect post-mortem disarticulation prior to burial. Don’t miss this opportunity to own a true milestone in early arthropod evolution. Questions? We’re happy to help. Contact us for additional photos, details, or scientific references.
