複数の Daguinaspis ambroggii の死亡プレート。スース・ラゲステット、モロッコ - 動物化石

Description
Very fossiliferous slab with a cluster of five (5) adult Daguinaspis ambroggii (Hupé & Abadie, 1950) dorsal external molds, from the Lower Cambrian Souss Lagerstätte, Morocco – ~521–515 million years old. Featuring collective behaviour (or possible diagenetic enrollment) with exceptional overall preservation. No restoration whatsoever.


MY GRADING FOR THIS SPECIMEN: 5/5 ***** — several Daguinaspis mortality slab (rare!), great anatomical preservation, pronounced tridimensionality (signature of rapid burial in the Souss Konservat-Lagerstätte).

Trilobite Size (largest Daguinaspis, for reference): 3.4 × 1.7 cm (big for the species!)

Matrix Size: 14.5 × 14.5 cm

Weight: 390 g


Taxonomy
Daguinaspis ambroggii (Hupé & Abadie, 1950)
Family: Fallotaspididae
Order: Redlichida
Class: Trilobita.

Lithostratigraphy: Upper Amouslek Formation

Age: Lower Cambrian (Series 2, Stage 3) — ca. 520–515 Ma

Biostratigraphy: Daguinaspis Zone, Issendalenian

Locality: Tazemmourt Section, northern slope of the Western Anti-Atlas, Morocco

Collected: February 2025


This scientifically significant slab presents a rare assemblage from Africa’s first and oldest Cambrian Lagerstätte — a true window into early animal community dynamics.


Note the characteristic, perfectly preserved heart-shaped cranidia of the adult D. ambroggii specimens, the elegant 3D relief across the entire cluster (minimal compression, indicating rapid burial conditions and early diagenetic cementation), and the conspicuous, well-preserved pleural spines on nearly all individuals — a testament to the extraordinary taphonomic fidelity of the Souss biota.


This split is not just lucky — it’s a representative sample of the world-class fossiliferous potential that defines the Cambrian Souss Lagerstätte, where soft-tissue impressions, articulated clusters, and behavioural signals are routinely preserved. And were I have the luck to do my main research :-)


Authenticity & Preparation
100% natural – no painting, no shadowing, no composite additions.
No restoration — the slab is presented exactly as collected.


Perfect for serious collectors and museums seeking a scientifically significant, display-ready Cambrian fossil assemblage. It is representative from the only known trilobite-bearing Lagerstätte in Africa and deserves a place in any institutional or private collection.

********

All our trilobites were repaired after being broken at the settlement (they were glued in the lab). The vast majority don't suffer any reconstruction (=restoration) or composition. That's something we are proud to maintain as a philosophy in our work. If so, we'll tell you for sure right here.

Legally sourced and shipped from Portugal with registered tracking.

Do not hesitate to ask any questions. We will be more than happy to provide any additional details.
