Spiny Ceratarges Trilobite Fossil on Matrix from Morocco (299.6 grams)

Trilobites, an early arthropod relative of spiders, horseshoe crabs, and scorpions, preserved in this level of detail only occurred as a result of very sudden underwater landslides c...

This is an extremely ornamented member of the trilobites' well-known and globally distributed Lichid family. These trilobites have adapted for extreme defensiveness. Their long genal appendages afford them controlled escape from the water column...

Psychopyge elegans is a trilobite species from the Devonian Hamar Laghdad deposits near Alnif, Morocco. It is a member of the Order Phacopida. The species is known for its strange sh...

Ptychopariida is a large, heterogeneous order of trilobite containing some of the most primitive species known. The earliest species occurred in the second half of the Lower Cambrian...

This 100% complete trilobite fossil of the species crotacephalina on its natural limestone matrix is estimated at approximately 400 million years old, dating back to the Devonian per...

This beautifully preserved Crinoid fossil showcases intricate arm structures radiating from a compact calyx, all naturally embedded in sandstone matrix. With distinct detail and orga...

This fossil of ammonite, names Goniatite, from Morocco, is presented on an unique custom stand, made to be aesthetic and discreet. The ammonite is polished, showing a nice black and...

The extraordinary fossil Harpes trilobite, measuring eight four millimetres overall, is a wonderfully articulated and fine specimen. Exotic trilobites have influenced some of the most iconic sci-fi films and helped shape the structure of some of the most sophisticated architectural buildings in modern times. The Harpes trilobite, with its unique patterning and streamlined aesthetic, is a species that never fails to intrigue. Its wide, heavily pitted brim, fringe with a curled rim, and elegant taper to the point of both cephalon long spines make it a true enigma. The eyes set back high on the glabella, and the well-defined thoracic segments add to its allure for inquiring minds. With reference once more to the Martian-looking brim, this wide brim with innumerable pitting could have aided the invertebrate lift, much like a hydrofoil. Again, this is the theory at this time. Palaeontologists theorise the possible functions of these anatomical features, either being a wide sieve to filter bottom sediments for food or to detect movement, a sensory organ. Over the 250,000,000-year range of the trilobites, many different morphological adaptions developed from free swimmers to bottom sifters. The expanded and pitted cephalic fringe, a distinct anatomical development seen in harpetids and trinucleids types, including the Harpes trilobite, is a significant area of study in palaeontology. This species, featured in a beautifully designed lucite display case...
