Quick question...
Does anyone have any information on the Pectinid clam genus Clavicosta? I have been trying to identify a couple of spiny shells I found at the Wilson Clay Pit in central Texas. I have a lead, but I cannot find much information on the genus other than Newell describing it in 1938 in Late Paleozoic pelecypods: Pectinacea. University of Kansas Publications, State Geological Survey of Kansas 10(1):1-123. I looked up the book, but I don't have $100 to buy it on Amazon!
Thanks in advance to anyone who might be able to help.
