Portugese Trilobite Pair
Ogyginus forteyi
Arouca, Portugal
Lower Ordovician
13 x 18 inches each
In fossiliferous sedimentary stone, a fortuitous circumstance may occur in which a fossil, lying on the cleavage plane of a slab, is split in two, revealing two fossils in one. Here, both halves of an impressively large trilobite specimen are well-preserved in the richly colored, deep gray matrix of their locality. The famous Portuguese quarry in Arouca, which sporadically yields slabs of black slate with unique fossils, displays an unusual mineral replacement - the presence of numerous small iron pyrite crystals. The present trilobite specimen lived during the earliest epoch of the Ordovician Period, which extended from 490 – 460 million years ago. Trilobites, once dominant in the marine environment, were the first creatures on Earth to possess eyes.

Massive Trilobite Plaque
Acadoparodoxides
Tikniouine, Anti-Atlas, Morocco
Cambrian
Matrix measures 96 x 45 x 2in, largest trilobite measures 13 1/2in
Over the last decade, Morocco has become famous for its amazing array of trilobites. This rare, massive plate, featuring over 15 large, complete and partial, Acadoparadoxides trilobites, represents one of the finest totally natural assemblages ever to emerge from North Africa. The mere size and orientation distinguish this natural plaque. This is a piece that will appeal equally to the advanced collector and to those who have a keen eye for especially attractive fossil pieces. A cataclysmic event was responsible for the sudden death and burial of this mass of creatures. Every specimen is natural and unrestored. Matrix measures 86 x 45 x 2in, Largest Trilobite measures 13 1/2in

Rare Spiny Trilobite
Hoplolichas plautini
Wolchow Valley, Russia
Ordovician
Measures 5 ¾ x 5 ½ x 1 ¾in
If there was ever a creature that resembled an alien from a distant galaxy, this 450 million-year-old Hoplolichas plautini trilobite from Russia is unquestionably the one. With its amazing free-standing defensive spines (each brilliantly prepared) and pristine caramel-colored exoskeleton, this is one of the most beautiful and rare of all trilobite species.
