Illeanus sarsi, Ordovician, SWE

Light brown, almost pastry-colored large trilobite standing out beautifully from the mica-rich, silvery-grey silt matrix, which makes it popular with collectors. The deformation is tectonic and characteristic of this species from this region.The genus was buoyant and an active predator.Age: Middle Ordovician, Llandeilo (correlates with Darriwilium);Locality: Valongo, Norte region, PortugalSize trilobite: 8 cm; matrix: 13.5 x 10 Colors in photos may differ slightly from the original for technical reasons.   

Rust-brown large trilobite on a massive stone block, which also contains gastropods of the genus Platyceras and brachiopods.Ectillaenus giganteus was buoyant and an active predator.Age: Middle Ordovician, Llandeilo (correlates with Darriwilium)Locality: Ciudad Real, SpainSize trilobite: 6 cm; matrix: 15 x 9 x 6 cmColors on photos may differ slightly from the original due to technical reasons.   

A trilobite pygidium and cephalon, exceptionally well preserved on little matrix, very detailed.Age: Ordovician, Sandbian, Letna Fm;Locality: Beroun, Czech RepublicSize: Cephalon - 4 x 2 x 1 cmColors on photos may differ slightly from the original due to technical reasons.

Trilobite pygidium and cephalon, preserved in remarkable detail on little matrix.Age: Ordovician, Sandbian, Letna Fm;Locality: Beroun, Czech RepublicSize: Cephalon - 5 x 2,5 x 1 cmColors on photos may differ slightly from the original due to technical reasons.

Beautifully preserved trilobite with clear segmentation.The locality in the Czech Republic is no longer accessible!Ellipsocephalus hoffi was entirely sightless and inhabited deep, low-light zones of the ocean. This species also curled up differently: Its micropygidium was folded under the thorax and cephalon (double fold), while other trilobites curled up like woodlice.Age: CambrianLocality: Czech RepublicSize of trilobite: approx. 1.5 - 2 cmColors on product photos may differ from those of the original specimen due to technical reasons.

Very decorative trilobite on matrix.A characteristic trilobite of the Wheeler Shales, which can compete with the Burgess Shale in diversity and conservation.Age: Cambrian, Wheeler Shale;Locality: Utah, USA Fossil size: approx. 3 x 2 cm Matrix: 8.5 x 7.5 x 1.5 cmColors on product photos may differ from those of the original specimen due to technical reasons.
