Foshunter Posted September 17, 2015 Share Posted September 17, 2015 Was looking through boxes for an ammonite and found what I thought was a starfish arm but now not sure. This is an old find from the Sulphur R. Ozan Form. Any ideas, the back side is featureless and the front not much better Tom Grow Old Kicking And Screaming !!"Don't Tread On Me" Link to comment Share on other sites More sharing options...
fossilized6s Posted September 17, 2015 Share Posted September 17, 2015 The ribbing says Cephalopod, to me. Can we get a look at the larger broken end, inside? ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...
belemniten Posted September 17, 2015 Share Posted September 17, 2015 ii agree with him i also think its a Cephalopod Many greetings from Germany ! Have a great time with many fossils Regards Sebastian Link to comment Share on other sites More sharing options...
Foshunter Posted September 17, 2015 Author Share Posted September 17, 2015 Thanks, The ends are featureless, this seems to be a cast of what ever. ID will depend on features on the one side, if that is any help Tom Grow Old Kicking And Screaming !!"Don't Tread On Me" Link to comment Share on other sites More sharing options...
Ptychodus04 Posted September 17, 2015 Share Posted September 17, 2015 looks like a cephalopod to me as well. Reminiscent of the Pennsylvanian ones from the Bridgeport/Mineral Wells areas. Of course, this one is Cretaceous.

Herb Posted September 17, 2015 Share Posted September 17, 2015 the orthocone cephalopod that I know of in the Cretaceous is Baculites sp. Most others had died out by the late Triassic. I'm sure someone will correct me if I am wrong. :-) . The chambers seem awfully close together?

Plax Posted September 17, 2015 Share Posted September 17, 2015 looks like a pelecypod tube to me, can't think of the name off hand but maybe gastrochaena? wild guess Link to comment Share on other sites More sharing options...

I'm sure someone will correct me if I am wrong. :-) . The chambers seem awfully close together? I thought they were pretty close, too. That's why I wanted to see if there was a siphuncle present. Being a river find though, it could have washed in from somewhere else. Just a thought. ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...

Being a river find though, it could have washed in from somewhere else. Just a thought. Where it was found was a portion of the river I called linestone falls. The area had an uplift of soft limestone and the piece was imbedded in it. That area has now been washed flat. I know there isn't much detail in the piece, this is the only one have collected or seen, it is a big?

Guguita2104 Posted September 18, 2015 Share Posted September 18, 2015 I'll say belemnite phragmocone...It doesn't seem baculites, because we can't see the flower shaped suture lines. Here is a litography of one: Regards, Link to comment Share on other sites More sharing options...

Here are a litography of one: Belemnite.png Regards, I believe you have solved the mystery, I am amazed that anyone could even ID this fossil from the lack of well defined detail. Found thes publication that shows Belemnite in the Cretaceous of Texas.

Wrangellian Posted September 18, 2015 Share Posted September 18, 2015 You don't always see the sutures on bacs, if the outer shell is present or if you only have a living chamber. But I am troubled by the faint ribbing I see. I have seen no baculites or belemnites with that kind of ribbing - on Bacs usually the ornamentation is more widely-spaced and slanted/sinuous (a bit S-shaped), and belemnites are usually smooth, no? Someone will no doubt correct me if I'm wrong, maybe there are bacs or belemnites with that kind of ornamentation. If there was a chance this was from the Penn. I would guess Conularia (or maybe an orthocone?). Otherwise I am stumped. Link to comment Share on other sites More sharing options...

Wrangellian Posted September 18, 2015 Share Posted September 18, 2015 That's not ribs, but growth lines, that are common in belemnites. Are you sure? They look 3-dimensional (the growth lines I've seen on belemnites have all been 2D). Link to comment Share on other sites More sharing options...

abyssunder Posted September 19, 2015 Share Posted September 19, 2015 Very interesting thread. I see a lot of possible variants. Hard to decide which one is the most appropriate for the best ID. For all that, is that possible to see a picture from the opposite side of the specimen?

abyssunder Posted September 19, 2015 Share Posted September 19, 2015 I know that it's from Upper Cretaceous,Tom, and my guess could be that it's a piece of heteromorph ammonite of the family Diplomoceratidae.

erose Posted September 20, 2015 Share Posted September 20, 2015 I'm also not convinced it's a belemnite and it definitely isn't a Baculites. All the belemnite casts I have ever seen tapered much quicker than that.the angle is just too small. Also never seen one that was flattened. Are you 100% sure this is from the Sulfur River? It looks way more Paleozoic to me. Link to comment Share on other sites More sharing options...
Guest GemstoneAndFossil Posted September 20, 2015 Share Posted September 20, 2015 This looks similar to a recent find of mine , I will post pics asap , is there some kind of limit to picture posts ? Link to comment Share on other sites More sharing options...
