New xiphosuran merostomata from the Upper Carboniferous of the Graissessac Basin (Massif Central, France)

Carboniferous merostome arthropods are relatively diversified, but their remains are rare, especially in France. A new specimen has been collected from the southern part of the Massif Central (France). This new taxon of xiphosurid, assigned to Euproops mariae n. sp. from Graissessac, is described; comparisons with closely allied species from Europe are discussed. Based on the associated macroflora, the material is considered to be Stephanian B–C in age. To cite this article: C. Crônier, P. Courville, C. R. Palevol 4 (2005).
