Digestive structures in Middle Ordovician trilobite Prionocheilus Rouault, 1847 from the Barrandian area of Czech Republic

Original language description

Remains of digestive system preserved in lightly damaged articulated specimen of comparatively rare calymenid trilobite Prionocheilus vokovicensis (Šnajdr, 1956) are described for the first time. The specimen comes from the Middle Ordovician Šárka Formation of the Prague Basin and contains a post-stomach part of alimentary canal preserved through the axial region of glabella and seven (possibly eight) anterior thoracic segments. The anterior-most part of digestive system is unknown as the anterior glabellar lobes are not preserved in the studied specimen. In the cephalic shield, remains of two posterior glabellar gut diverticulae are seen in the left side of glabella. Six (possibly seven) pairs of small cavities developed right and left of gut represent remains of thoracic gut diverticulae. The discussed specimen is the first undoubted examples of digestive structures within the family Bathycheilidae Přibyl, 1953.
