Goldene Mortality-Platte Daguinaspis – 1,3 cm Trilobit – Tazemmourt - Tierfossil (Ohne mindestpreis)

Golden Positive/Negative Inter-Specific Mortality Plate Daguinaspis ambroggii (Hupé & Abadie, 1950) + Brevipelta chouberti (Geyer, 1994) + Nevadotheca (?) sp. – Souss Lagerstätte, Morocco | PAIS9575

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 three (3) species from three (3) different animal groups; Complete Daguinaspis (with 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 a juvenil 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 and Nevadotheca (?) sp. with the trilobite exoskeleton and other detached tergites. Also present a Daguinaspis early Holaspid (H0) cranidium - see high magnification pictures.
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. The trilobite was prepared to proper display.

Why This Stands Out?
• Juvenil 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 three (3) species from three (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 (PAIS9575)
• 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.
