old bones Posted March 2, 2014 Share Posted March 2, 2014 (edited) Here are some of my first finds from the matrix sent to me by member Sacha. It is pebble matrix from the Rattlesnake Creek in Gainesville, Florida. Mostly Miocene. The colours of the teeth are really nice, and the preservation is excellent. I have attempted to ID what I can, but please correct me if I am wrong. First, here are some shark teeth. I think that 'A' and 'D' are Carcharhinus. not sure about the rest... Again, I think 'A', 'D', 'E', and 'I' are Carcharhinus. I had to add this one just to show the great colours! I realize that these are probably too worn to ID, but 'C' looks like a Hemi. Some of these teeth are almost translucent. I already know 'E', and 'F' are Lagodon, as I have found one of those before. And the crushing teeth are 'A', 'C', and 'D'. 'B' and 'G' are new to me tho.

old bones Posted March 2, 2014 Author Share Posted March 2, 2014 continued; I believe that this is a dermal element. These are mostly ray teeth I think ... I think that 'C', and 'I' are Rhynchobatus. And 'G' is Daysyatis. Isn't 'C' a neat colour?! I would love to know what this vert came from. I am amazed that it is in such good condition. Looks like it is missing a process on the opposite side.

old bones Posted March 2, 2014 Author Share Posted March 2, 2014 last one. This bone looks like fish, and there appear to be tooth sockets. I have included several angles. And what is the little chalky thing? I have found several of these. Thanks for looking.. Link to comment Share on other sites More sharing options...
Al Dente Posted March 2, 2014 Share Posted March 2, 2014 The little chalky thing is a foraminiferan, possibly lenticulina. Link to comment Share on other sites More sharing options...
old bones Posted March 3, 2014 Author Share Posted March 3, 2014 The little chalky thing is a foraminiferan, possibly lenticulina. Thank you Al Dente! I looked them up, and that sure looks like it. They are small! Now I have a whole new group of things to learn about and keep in mind while searching matrix. I just have a magnifying glass, no telling what I could find with a microscope!

Sacha Posted March 3, 2014 Share Posted March 3, 2014 Julianna, your pictures are great and you've found allot of great stuff already. Keep it coming! Link to comment Share on other sites More sharing options...
old bones Posted March 3, 2014 Author Share Posted March 3, 2014 Thank you John and thank you for sending the matrix. It is really nice to see all the neat colours and what a terrific variety of specimens from this site. I am really enjoying this! Link to comment Share on other sites More sharing options...
lissa318 Posted March 3, 2014 Share Posted March 3, 2014 Could 3rd picture D be hammerhead? Looks similar to some of mine? Nice finds!!!!! Link to comment Share on other sites More sharing options...
old bones Posted March 3, 2014 Author Share Posted March 3, 2014 Hey Lissa. Could be... I just don't have much confidence yet in shark tooth ID. Lol the colour of that tooth is something else tho. Some in this matrix are almost lavender. And they are still sharp! Link to comment Share on other sites More sharing options...
MarcoSr Posted March 4, 2014 Share Posted March 4, 2014 Great pictures. Really nice specimens. I really do like the colors of the teeth from this site. Here is what I think: 1st picture: D might also be Negaprion, E - Carcharhinus. 2nd picture: B – Carcharhinus, E could also be Sphyrna, F- Negaprion, I could also be Rhizoprionodon. 3rd picture: A, D, F – Carcharhinus, C does look like Hemipristis. 4th picture: A – Sciaenidae (drum) 5th picture: Looks like a ray dermal element (thorn) 6th picture: A, B, G - Dasyatis, and yes C, I look like Rhynchobatus 8th picture: Agree with Al Dente Marco Sr. 1 "Any day that you can fossil hunt is a great day."

old bones Posted March 4, 2014 Author Share Posted March 4, 2014 (edited) Marco Sr, thank you very much for taking the time to look at these and helping me to ID them. Now I can label these correctly for my gallery images that I am working on. ( If I can ever get away from searching matrix! lol ) Each time that I get an ID from you and the other fine folks on here, I can recognize it for future specimens.

For some teeth you may have several possible ids because different genus/species can look so similar. Even experts looking at some teeth feature by feature can't make a 100% id. The more teeth you see the easier it will be to id them. Marco Sr. "Any day that you can fossil hunt is a great day."

Herb Posted March 6, 2014 Share Posted March 6, 2014 nice finds. Is it just me or does every state in the Union have a "rattlesnake" creek?
