luklaus Posted November 12, 2011 Share Posted November 12, 2011 Found in Hickory Creek(Ardmore OK) gravel bar alongside some cret bones. I'll post the bones later, not enough to identify...but maybe??. This is something members of our club have found before and nobody seemed willing to research, but now I have one lol It's not the mountain ahead, but the minerals in my shoe...."Siddartha" You'll find me hanging round www.sgams.net Oklahomas Finest Link to comment Share on other sites More sharing options...

LanceH Posted November 12, 2011 Share Posted November 12, 2011 The left one looks like concentric layers of elephant tusk or part of tooth roots, but my Pleistocene is weak. Link to comment Share on other sites More sharing options...
Rob Russell Posted November 12, 2011 Share Posted November 12, 2011 If they are indeed marine fossil's I'd go with a piece of orthoconic naulitoid or possible sphuncle mold. The second a cephalopod of some sort. Perhaps from the michelinoceroid or endoceroida families. Finding my way through life; one fossil at a time.

luklaus Posted November 13, 2011 Author Share Posted November 13, 2011 from the outside the first one looks just like the second. I found another one in my rock pile and this one got cut...at the time we thought it was a chert concretion but now I kinda wonder....I'll post it directly, but I'm having a water pump issue and it takes precedents It's not the mountain ahead, but the minerals in my shoe...."Siddartha" You'll find me hanging round www.sgams.net Oklahomas Finest Link to comment Share on other sites More sharing options...
luklaus Posted November 13, 2011 Author Share Posted November 13, 2011 I really gotta do the pump but I noticed there are some fine details my camera didn't pick up...I've got a macro lens and tripod so I'll post more ...later It's not the mountain ahead, but the minerals in my shoe...."Siddartha" You'll find me hanging round www.sgams.net Oklahomas Finest Link to comment Share on other sites More sharing options...

luklaus Posted November 13, 2011 Author Share Posted November 13, 2011 All three fossils seem to be the same thing, I'm really getting a hard time about these thangs. They are found in gravel beds usually. My friend also has one and it is very similar. I am just mis-keying like crazy, must be tired...

Ludwigia Posted November 13, 2011 Share Posted November 13, 2011 Is it possible that paleozoic rubble also finds its way into these gravels. Those look like broken bits of a large Nautiloidea at first glance or part of a belemnite septum. Is the substance all recrystalized or do I see bone substance in there too?

luklaus Posted November 13, 2011 Author Share Posted November 13, 2011 The lighting was not right for pics,but... Is it possible that paleozoic rubble also finds its way into these gravels. Those look like broken bits of a large Nautiloidea at first glance or part of a belemnite septum. Is the substance all recrystalized or do I see bone substance in there too? It looks to me like chert, but then again it could be. Do you know what those fine cross-hatched lines are that you can see if you look at the holes where it's broken out. Post number 8 and 9 ..both on left side. If you download you can blow them up a lot It's not the mountain ahead, but the minerals in my shoe...."Siddartha" You'll find me hanging round www.sgams.net Oklahomas Finest Link to comment Share on other sites More sharing options...
Ludwigia Posted November 13, 2011 Share Posted November 13, 2011 (edited) Do you know what those fine cross-hatched lines are that you can see if you look at the holes where it's broken out. I've seen things like that before under various circumstances, but can't really say what they are. I must say, this has me confounded, but I'm still thinking Nautilus.

luklaus Posted November 14, 2011 Author Share Posted November 14, 2011 I think it's amazing that I've got three of something , nobody has.... Really the photos don't do this specimen justice, they are heavy like a rock and all three have a central spine or ...shall we say, stem. The preserved fossil is "hard" like a 6.5 on mohs scale. Will take a polish real nice. The vugs or cavities are filled with non-crystalline quartz. Things from the Pleistocene aren't agatized...probably not the cretaceous either.

Xiphactinus Posted November 14, 2011 Share Posted November 14, 2011 that last photo helps a lot. This one specimen at least is a weathered cephalopod. Link to comment Share on other sites More sharing options...

Maniraptoran Posted November 14, 2011 Share Posted November 14, 2011 6.5? you must have a piece of the tail end of the cephalopod shell. that part is so densely clacified it feels more like metal than stone. Link to comment Share on other sites More sharing options...

luklaus Posted November 14, 2011 Author Share Posted November 14, 2011 6.5? you must have a piece of the tail end of the cephalopod shell. that part is so densely clacified it feels more like metal than stone. I'm basing this on the polish that is on specimen 3, and also having polished many different type of agates. I used a scratch test, except it didn't scratch.I'm not sure about "calcified"....wouldn't that be a lot softer, like calcite.

TqB Posted November 14, 2011 Share Posted November 14, 2011 From those good last pics, I think that one may be an actinoceratid nautiloid - they have large siphuncles, expanded between the septa as shown in the photo (thanks, Treatise!). From the hardeness, sounds like they're silicified - very nice! Tarquin Link to comment Share on other sites More sharing options...
luklaus Posted November 14, 2011 Author Share Posted November 14, 2011 (edited) I googled "actinoceratid nautiloid" and I agree..thanks everybody I really appreciate the effort. This is a great place to post for sure. I have more mysteryies coming up Edited November 14, 2011 by luklaus It's not the mountain ahead, but the minerals in my shoe...."Siddartha" You'll find me hanging round www.sgams.net Oklahomas Finest Link to comment Share on other sites More sharing options...
