JohnJ Posted July 9, 2008 Share Posted July 9, 2008 This past weekend I explored some new places that didn't pan out too well. So I headed back to a place in the Upper Cretaceous (possibly Austin Chalk) I call "Ammonite Bluff" (see my gallery). In the past, I've seen cast sections of huge ammonites (up to 4 ft. in diameter) eroding from this bluff. This time, I ducked a low tree branch and raised my head to see this wonderful 14" nautiloid cast! It's my largest find of this type. I'm short on reference material to assist with an ID...anyone??? On the 4th, I picked up these two at a different location, but similar formation. However, the fun started on the 3rd with this Texas Archaic blade!

Auspex Posted July 9, 2008 Share Posted July 9, 2008 Oh Wow! Looks like you had a great time. Any one of those finds would have made my weekend.

Roz Posted July 9, 2008 Share Posted July 9, 2008 That is one of the best, intact ones I have ever seen from Texas. Sorry that I cannot help with the ID. Welcome to the forum! Link to comment Share on other sites More sharing options...
Uncle Siphuncle Posted July 9, 2008 Share Posted July 9, 2008 John There aren't nearly as many genera of nautiloids as ammonites documented in the Texas Cretaceous, but I'd bet a paycheck you have either Cymatoceras or Eutrephoceras of one species or another. If memory serves Cymatoceras sort of ended its reign in Austin times and Eutrephoceras took over in Taylor and Navarro seas. Perhaps someone with more concrete facts can step in at this point. Holler at me about possibilities for this coming weekend. Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils." Link to comment Share on other sites More sharing options...
