Species: Chotecops ferdinandi

Location: Bundenbach, Hunsrück, Germany

Age: Lower Devonian

Chotecops is a genus of trilobites from the order Phacopida, suborder Phacopina, family Phacopidae. It was initially erected as a subgenus of Phacops but some later authors thought it distinctive enough to raise its status. Species assigned to this genus occur between the Emsian and the Famennian. Chotecops is the most sought after trilobite in the Hunsrück Slate due to the excellent preservation.

Like in all sighted Phacopina, the eyes of Chotecops are compounded of very large, separately set lenses without a common cornea (so called schizochroal eyes), and like almost all other Phacopina, the articulate mid-length part of the body (or thorax) in Chotecops has 11 segments.

 

The central raised area of the cephalon (called glabella) consists from back to front of an occipital ring, but unlike in its close relative Phacops the preoccipital ring in Chotecops is flat and not reduced to its sides, and the furrow defining its front (S1) is shallow. One or two pairs of furrows (S2 and S3) may be visible further to the front which are weak at best. The large frontal lobe is moderately vaulted and falls steeply to the furrow that defines the border at its front. The space between the glabella and the eyebrow (or palpebral area) is flat. The headshield has a finer sculpture. The tailshield (or pygidium) is weakly furrowed. These characters distinguish it from Phacops.
