New record of the Early Jurassic myriacanthid holocephalan Myriacanthus paradoxus AGASSIZ, 1836 from Belgium

A right upper posterior ("palatine") toothplate from the Grès de Florenville (bucklandi zone, Lower Sinemurian, Early Jurassic) of Clairefontaine (Belgian Lorraine) is described and identified as Myriacanthus paradoxus AGASSIZ, 1836. This, the first record in Belgium, extends the known palaeogeographical range of the species.
