Abstract

This article highlights the role of Jean-Baptiste Beurard in the history of palaeoichthyology. A former canon of the Cathedral of Toul, he became a government employee attached to the mine administration between 1794 and 1815 after the turmoil of the early revolutionary period. He was in charge of supervising the mercury mines in the new departments annexed by France on the left bank of the Rhine. In July 1799, he rediscovered in the area of Münsterappel the famous Lower Permian deposit of “ichtyolites” (fossil fish) impregnated with cinnabar. He sent several specimens to institutional collections in Paris. Representatives of the species Paramblypterus duvernoy (Agassiz, 1833) (Actinopterygii, Amblypteridae), probably sent by Beurard before 1809 according to the testimony of Barthélémy Faujas de Saint-Fond, have been identified in the collections of the Muséum national d’Histoire Naturelle, Paris. Another specimen that indisputably belonged to Beurard is preserved in the Geosciences Collections of the Sorbonne University (Paris) and is of particular historical interest. Beurard also possessed in his collection two samples of fossil fish from the Cenomanian of Haqel, in present-day Lebanon, received from his nephew Claude Charles Harmand (1784–1847), naval officer, in 1817. Based on those specimens, Henri Marie Ducrotay de Blainville described and named the two species Clupea beurardi Blainville, 1818a, and Clupea brevissima Blainville, 1818a. The first one is no longer considered valid and the second one is now assigned to the genus Armigatus Grande, 1982 (Actinopterygii, Clupeomorpha), of which it is the type species. One of these specimens is kept at the Natural History Museum, London, and comes from the collection of William Willoughby Cole (1807–1886), Earl of Enniskillen, who had acquired part of the Beurard collection. Erroneously labelled Clupea beurardi by Beurard, this sample actually bears the four syntypes of Armigatus brevissimus. A lectotype is designated here to settle the identity of the species, which is certainly the most abundant and iconic one found in the Haqel deposit.
