A new specimen of aistopod from the famous Stephanian deposits of Montceau-les-Mines was discovered in the collections of the Muséum d’Histoire naturelle d’Autun. It is the first nodule of this site that has been studied by X-ray tomography. This specimen is probably a juvenile of the genus Phlegethontia, also known in the Westphalian of North America and eastern Europe. The teeth of this animal seem pedicellate, which would reveal that this character was more homoplasic than previously suggested. It also seems that aistopods were terrestrial rather than aquatic.
