My first Metengonoceras dumbli ammonite at the Walnut formation. Although not complete, I've been searching this species of ammonite for many years. Plenty of Oxy's, but never ever found this one. This one measures around 4.5 inches / 114.3 mm.

Central Texas Coryell County Walnut Formation bivalve fossil ID
Creek - Don posted a topic in Fossil ID
Went out to the Central Texas Coryell County and looked for some Early Cretaceous fossils. I recognize most of these fossils like Exogyra Texana, Gastropods, and clams I found before, but I can't seem to ID one long elongated bivalve that looks a modern razor clams.

I had a couple long time collecting friends roll through from out of state recently, and the responsibility of a successful outing fell on my shoulders more so than usual since our last outing a year or 2 ago was a bust. I had a full itinerary of sites to roll through, beginning with one in the Walnut Formation (Albian) where I had scored a career high of 68 Phymosoma texanum echinoids 2-3 years prior. We never made it to the other sites. I picked up the first P. texanum within the first 15 seconds on site, and over the next 2-3 hours, our combined take exceeded 100. Many were dusted with glittering marcasite, hard to see in the pics, but will be abundantly evident post prep. There were spatangoids present as well, dominated by Heteraster texanus, and including something in the Hemiaster/Toxaster group with 5 depressed ambulacra. I also picked up a svelt Engonoceras ammonite, thin and fragile, usually found in fragments. Always satisfying to hear your guests exclaim, “Now I have a lifetime supply of this species.” I think I’ll let this place go fallow for a while, then put my wife on point next round.
