    Cyphaspides Trilobite 80mm

    £482.00
    Jorf Cyphaspides sp. trilobite discoveries are unearthing some beautiful opaque and in some cases, almost translucent calcified carapaces, the hardness of the limestone here creates crisp definition when complete individuals are conserved to a high standard as is the case here. The right-hand genal spine to this specimen has a translucent quality when viewed under a powerful lens, a result of the mineralisation within the deposition of the fossil layer. The vaulted cephalon and thoracic segments crisp and well defined, these running through to the pygidium and it's two recognisable longer pygidial spines. Genus: Cyphaspides sp.

    Drotops Megalomanicus Trilobite 138mm

    £792.00
    Drotops Megalomanicus Trilobite 138mm. This fossil trilobite can still unveil a story of its evolution through the complex schizochroal eye, as multi compound eyes stand up from the cephalon, filled with a multitude of convex lenses, which were made up of the mineral calcite this having endured the test of time in its taphonomic state. Trilobites melted their exoskeleton or carapace, these carapaces are often found enrolled, like a defensive ball.

    Ceratonurus Spiny Trilobite 85mm in overall length in the fossil matrix which is found in the 'couche rouge', Red fossil layer, as is the Crotalocephalus trilobite at the same location in the same red layers. A remarkably well-preserved fossil arthropod displaying excellent preparation and conservation which enables us a glimpse back in time to the Devonian era, and into the life of this particular arthropod, invertebrate trilobites which once proliferated the sea's 400 million years ago. Some were free swimmers, most lived solely on the sea bottom, with appendages and spines which were for defence. The bottom of murky seas could have been a very poorly lit place, disturbed by the multitude of foraging marine life.
