barefootgirl Posted April 14, 2009 Share Posted April 14, 2009 Sweet finds man! You always seem to have lady luck on your side. In formal logic, a contradiction is the signal of defeat: but in the evolution of real knowledge, it marks the first step in progress toward victory.

Auspex Posted April 14, 2009 Share Posted April 14, 2009 A few Cook Mountain goodies....The biggest Ecm gastropod I've ever heard of.... Since I don't know anything from anything about your Cook Mountain stuff, I am free to appreciate without prejudice; I really like the gastropod "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!

MikeD Posted April 14, 2009 Share Posted April 14, 2009 That gastropod is amazing (and the jaw is cool, too)! I've not seen one like that. Do you have an ID? Link to comment Share on other sites More sharing options...
Uncle Siphuncle Posted April 14, 2009 Author Share Posted April 14, 2009 No sir Mike, that's why I showed it here...calling all experts! Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils." Link to comment Share on other sites More sharing options...

Awesome Dan, the jaw made me sit up and the gastropod put me back down. Keep 'em coming. Brian Brian Evans For every complex problem, there is a solution that is simple, neat, and wrong.

jkfoam Posted April 14, 2009 Share Posted April 14, 2009 Dan, I have never seen a snail that large in the Gulf Coast cook Mountain Formation. Now large snails are known in the Eocene. Pictured below is a snail I collected from the Eocene, Gosport Sand Fm, Claiborne, Alabama some years ago. It is Papillina papillata (Conrad) Now as to the identity of that snail you found in the Cook Mountain, I don't know. My first thought was that it was a Clavilithes sp.. You need to post some more pictures of that thing, better lighting on the bottom half and show the aperture. Below is a picture of a very large Clavitilithes macrospira from the Eocene, Barton Beds, in the UK. It is way bigger than the Clavilithes texanum from the Cook Mountain formation. JKFoam The Eocene is my favorite Link to comment Share on other sites More sharing options...
Uncle Siphuncle Posted April 14, 2009 Author Share Posted April 14, 2009 Jim Wow if you have never seen a gastropod that large from the Ecm, it must be something special as most folks don't have the experience in that formation that you do. I'll post more pics, but the aperture and bottom whorl are completely gone. It is clearly Ecm since I dug it out of the bedded exposure. I knew it was significant when my boy and I laid eyes on it, even though it isn't complete. I've since dipped it in thinned Butvar as it was very fragile with many cracks. Have you ever seen bone in the Ecm of TX? I'm curious to hear your take on that piece. Trust me, I've examined countless TX Pleistocene bones and precious few have the density of the specimen shown. Thanks for your input sir. Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils." Link to comment Share on other sites More sharing options...
MikeD Posted April 14, 2009 Share Posted April 14, 2009 Sent your picture to the experts that I know (that are not on this forum). Looks like jkfoam nailed it. Here is what one of them said: "Hey Mike, that’s a beauty, his name is Clavilithes sp. The spelling may be off by a letter or two there, but he is supposedly a Weches-Only formation type of guy. I’ve found a few large pieces similar to that one and one large full specimen all in Weches formation outcrops. Very nice specimen. Thanks again for the photo; keep ‘em coming. Chris" He also sent this. Link to comment Share on other sites More sharing options...
tracer Posted April 14, 2009 Share Posted April 14, 2009 dan - the archaeocete whisperer - um, look. does the thing have a bunch of cancellous bone showing on the breaks? let's face it, the density is probably due to mineralization which could easily have occurred over early pleistocene type time frames. it being found on float atop Ecm sounds kinda like it was evicted from its real home and ended up squatting on a big pile of diagenetically altered gastropod poop. my guess would be that it hails from one of the usual megabiggiefaunal suspects, a la mammoth, nipple tooth, or "big lazy". but your poundage may vary.

Thanks for your input sir. Dan, All my Paleontologist friends always reminded me to be on the look out for evidence of whale in my collecting in the Texas Eocene, but I never found anything or heard of anyone else finding any. As far as finding any bone all I ever found was a few fish bone pieces and they were small. This is not to say that mammal bones are not present in the Cook Mountain Fm. D.T. Dockerty in his publication " The Invertebrate Macropaleontology of the Clarke County Mississippi Area" states that the Archusa Marl Member of the Cook Mountain Fm has a land mammal locality where titanothere bone was collected (page 45). Of course, there is always the possibility of Pleistocene material being washed into the Eocene exposure. Jim The Eocene is my favorite Link to comment Share on other sites More sharing options...
Uncle Siphuncle Posted April 14, 2009 Author Share Posted April 14, 2009 If I were sure this were Pleistocene I'd have skipped it across the ripples. I reckon I'll hold onto it for a while......

I reckon I'll hold onto it for a while...... it wouldna skipped. it woulda just sunk and laid there for years until somebody found it and said, "look, vinnie! eocene whaleans hunted with bb guns!"
