Roz Posted May 22, 2013 Share Posted May 22, 2013 This is a small bone that I found recently.. It is from the Pennsylvanian Period, Texas. I was really excited when it first opened because I thought those were teeth in the center but they are not. They seem to be fused together.. I thought someone might recognize it from something they have found.. I think it is part of a fish. The first shot is for size only with all the other shots through my loupe.. This shot is the negative side The rest are different views of the positive side Welcome to the forum! Link to comment Share on other sites More sharing options...
Roz Posted May 31, 2013 Author Share Posted May 31, 2013 This one I found recently.. I had hoped maybe a jaw with teeth although even with my loupe I can't tell. If they are teeth then that must be a jaw.. Does it look like a jaw to anyone else? Pennsylvanian period (Texas) Welcome to the forum! Link to comment Share on other sites More sharing options...

Batty Posted June 1, 2013 Share Posted June 1, 2013 The second one reminds me of a preopercle bone on a fish, but that's just me. It may be something totally different ( probably is lol) Link to comment Share on other sites More sharing options...
Bullsnake Posted June 1, 2013 Share Posted June 1, 2013 Hi, Roz I don't see jaw, other than the suggestive shape. Are there any fish that have teeth that extend up into the back of the jawbone (Ramus?)? It looks similar to the piece in your original post, only missing about half of it. Cool looking pieces. I'm surprised nobody recognizes them. Steve Link to comment Share on other sites More sharing options...

They do look somewhat similar although in the first fossil they look more like they are hinged together but if this one has only half it would appear like that I am thinking. I was sure hoping for a jaw but I will keep looking! Welcome to the forum! Link to comment Share on other sites More sharing options...
Missourian Posted June 1, 2013 Share Posted June 1, 2013 (edited) The problem with these bones is that they could just be parts of larger bones. If it came from within a cranium, it may be quite difficult to ID. I have so many in my collection with question-marks on the labels. Edited June 1, 2013 by Missourian Context is critical.

Batty Posted June 2, 2013 Share Posted June 2, 2013 That is a you.S. penny next to it.. Unfortunately I have no idea how big a penny is. I will have to try get some. I do have a dollar note though Link to comment Share on other sites More sharing options...

Roz Posted June 2, 2013 Author Share Posted June 2, 2013 Sorry, Batty.. I have a ruler but it doesn't photograph well.. Do you have M&M's (candy) in Australia? I always have plenty of those !! I will have to get a better ruler.. Welcome to the forum! Link to comment Share on other sites More sharing options...
Batty Posted June 2, 2013 Share Posted June 2, 2013 I only eat m&ms if the kids haven't found them first. Link to comment Share on other sites More sharing options...
Roz Posted June 12, 2013 Author Share Posted June 12, 2013 I am sticking another unknown here for possible ID.. The nodule is one half of an inch. Same age as the others.. (Pennsylvanian Period) Images are from different angles and are taken of both the halves of the nodule.. I am thinking one of you that hunts in the same period may have found one and knows what it is. Thanks! Welcome to the forum! Link to comment Share on other sites More sharing options...
Roz Posted June 29, 2013 Author Share Posted June 29, 2013 I think I am going to have to agree with Mitch that some of these may be from the cranium.. This one just opened recently and I think it visually matches something in one of Mitch's post of his fish head.. I just haven't figured out what it's called yet.. It's 3/4 of an inch.. Positive side and negative Thanks.. Welcome to the forum! Link to comment Share on other sites More sharing options...

Positive side and negative 100_5550-001.JPG 100_5552.JPG Thanks.. Ok, I received some suggestions in order of most likely for this one.. 1. a maxillary bone, from the side of the upper jaw. 2. Another possibility is from the lower jaw, or a branchiostegal ray from behind the jaw, or perhaps a bone from the shoulder girdle. Just updating.. Welcome to the forum!
