Fossilised guts in trilobites from the Upper Ordovician Letná Formation (Prague Basin, Czech Republic)
Original language description
The preservation of digestive structures of trilobites is extremely rare. Here we describe two new examples of trilobites from the Upper Ordovician Letná Formation (Prague Basin, Czech Republic), which display remains of the digestive system. The first specimen, assigned to Selenopeltis buchi (Barrande, 1846), exhibits cavities under the posterior part of the glabella and the axis of most thoracic segments. These cavities are interpreted as remains of metamerically paired digestive caeca and constitutethe first example of preserved digestive structures in the order Odontopleurida. The second specimen belongs to Birmanites ingens (Barrande, 1852) and displays a tube-like structure, filled with a finely-grained material, that runs under the axial lobe of the entire trunk. We interpret this structure as a gut infilling similar to that repeatedly observed in the Moroccan Basilicus calzadai. These specimens confirm that the depositional environment of the Letná Formation was locally favour
