GOLDEN MORTALITY PLATE Daguinaspis - 1,7 cm Trilobit – Tazemmourt - Tierfossil (Ohne mindestpreis)

Golden Positive/Negative Inter-Specific Mortality Plate Daguinaspis ambroggii (Hupé & Abadie, 1950) + Brevipelta chouberti (Geyer, 1994) – Souss Lagerstätte, Morocco | PAIS9576

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: 5/5 ***** - Museum-grade slab with two (2) species from two (2) different animal groups; Two complete Daguinaspis (one of them with clearly visible pygidium), 3-D detail, colour, positive/negative.
(Graded using our transparent 5-point system — see seller info for details.)

This extremely scientifically significant plate from the Lower Cambrian of Morocco features two 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, including the pygidium (rare !).
It is possible to observe a fossiliferous association of Brevipelta chouberti with the trilobite exoskeleton and other detached tergites.
The slab 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 specimens. Good size.

Collection Code: PAIS9575 | Collected: May 2024

Why This Stands Out?
• Two 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, including the rarely observed pygidium
• Museum-grade slab with two (3) species from two (3) distinct groups
• 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 (May 2024), fully documented provenance (PAIS9576)
• 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, pleurae and pygidium, 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).

Don’t miss this opportunity to own a true milestone in early arthropod, brachiopod and hyolith evolution.
