Klompmaker José Flores-Ventura Francisco J. Vega Ciencias de la Tierra Mexico Decapoda Crustacea Brachyura Campanian A new species of the homolid crab, Zygastrocarcinus carolinasensis n. sp., is reported from the Upper Cretaceous (upper Cam - panian) strata of Coahuila, NE Mexico. Only the anterior part of the ~8 mm wide carapace was preserved in addition to a part of the sternum (sternites 1-6). The sternum is the oldest figured example of a fossil homolid sternum, and also of the entire section of fossil Homoloida. The sternum seems to be similar to extant homolids in general outline, and to an earlier described Eocene homolid. Hitherto, Zygastrocarcinus spp. were only known from the northern part of the USA (Wyoming, Montana, and South Dakota). Thus, the new species extends the geographic range of the genus during the Cretaceous to much of North America. Additionally, this is the second fossil homolid known from Mexico. 2013 artículo científico 1405-3322 https://www.redalyc.org/articulo.oa?id=94348266009 en http://www.redalyc.org/revista.oa?id=943 Boletín de la Sociedad Geológica Mexicana application/pdf Sociedad Geológica Mexicana, A.C.
