Abstract:

We document body fossils of the xiphosurid (horseshoe crab) Euproops danae Meek and Worthen from lacustrine black shale of the Missourian interval of the Beeman Formation near Alamogordo, New Mexico. These xiphosaurids, associated with conchostracans, bivalves, microconchids, fish scales and a paleoflora, are from a likely freshwater lake deposit. This is the first report of E. danae from the western USA and the first documentation of xiphosurid body fossils in the Pennsylvanian of New Mexico.
