Parallelodon antiquus Barrois 1891
Abstract
Parallelodon antiquus Barrois, 1891 Original source Barrois (1891): 200, pl. 3 fig. 3a–b. Type stratum and age “Grès armoricain”; upper Arenig (Babin 1966), Middle Ordovician. Type locality “Chapelle-Glain”; Loire-Atlantique département, Region Pays de la Loire, France. Type material Whereabouts unknown. Remarks Douvillé (1913: 440) placed the species in Actinodonta Phillips in Phillips & Salter, 1848, followed by other palaeontologists (Dechaseaux 1952: 270; Eberzin 1960: 72), whereas Cox (1960) mentioned its true Parallelodon morphology. Pojeta (1971: 17–18) classified the species in “ Pseudarca [Siliquarca]” (Lyrodesmatidae). Amler & Friedel (2025) noted that P. antiquus does not show the typical morphological characteristics of Palaeozoic parallelodontids, particularly with regard to the hinge arrangement, and therefore, doubt the assignment to Parallelodon.
