Going through Permian matrix. We have found many teeth and other identifiable microfossils. I have also found many of these metallic looking dark rocks. Are they bone fragments, or partially melted rocks? Thank you.
-
Hello, I recently visited a Permian site near Waurika Pond and collected microfossils for my students to explore back in the classroom. Is there a guide to identifying these fossils out there somewhere or is piecemeal searching here the way to go. If not, I will be making the one page guide over the summer have it to offer. Any help on something simple for my elementary aged students would be much appreciated. IMG_0064.DNG IMG_0065.DNG

Just acquired this associated fish vertebrate, the size of the rock behind this is about 28 cm, and that site produces a lot of megalodon teeth so I think it’s a Miocene fish. I'm not sure if it's identifiable by the vertebrae alone.

Need the Teeth Experts, Peace River, Small Vertebrate Teeth ID help needed.
Bone Daddy posted a topic in Fossil ID
Hi Folks, Lately I have been finding a lot of small teeth in my sifter. Most are damaged and that doesn't help trying to ID them. I lack a reference collection and the necessary books to compare these to, so I am asking for some help from our resident Peace River and vertebrate experts. My photos aren't the best and I know that doesn't help, but I did my best with my dated camera and hand tremors. I have numbered the teeth in the photos and will provide notes for them below : 1) This is a complete tooth and a very attractive little guy. 2) This is a tiny complete tooth and I do not think it is a fossil. 3) This is a crown only. The roots are missing. 4) The crown is missing on this one. It's roots only and probably cannot be identified. 5) Broken tooth. 6) Broken tooth. 7) Crown only, no root. 8) Crown only, no root. 9) Broken small horse tooth or something along those lines. 10) Broken small horse tooth or something similar.

Hi everyone! I have no idea what this is. I looked up various scapulas and hip bones from various things (mostly reptiles) and could not find a match. It gets weirder though, while this one is from North Florida I have another almost identical one from the Moroccan Kem Kem! This piece measures 7.5 cm/2.95 inches long. The "fan" is 5.2 cm/ 2.05 inches wide. The base is 2.6 x 2 cm/ 1.02 x .79 inches. I'll try and get some pics of the Moroccan one but it broke and I have to fix it. What do ya'll think?

How to id Ice Age Mammal bones Book recommendations
jikohr posted a topic in General Fossil Discussion
Hi everyone! I've been dabbling in Ice Age Mammal material and I'm having a hard time differentiating isolated bones between all the different large hairy and not hairy beasts we had back then, particularly in the South Central and South East U.S. Does anyone know any good id books that can help with that? Thanks! -

Found the vertebrate in some landscaping river rock. I have no clue on the type of animal. I'm pretty sure it's part of a vertebrate but I could be wrong. The pointed thing I found by ft. Worth. I have no clue with that either.

Hello all! I’ve just gotten home from Tucson, it was a great show. Having taken a 5+ year hiatus on fossil collecting, this was a wonderful return to the community, and getting to talk to some of the kindest and most knowledgeable people in the world. While there was much less as far as fossils go compared to the last time I went, I found some really good things to add to my ever growing collection. Prognathodon Currii Tooth Morocco 2 1/2 in or 6 1/2 cm Dromaeosaurid Tooth (Unknown Species) Tegana Formation, Tafallit Morocco 2 1/2 in or 6 1/2 cm Nanotyrannus Tooth Lance Formation, Weston County Wyoming 0.9 in or 2.3 cm Osteitchthyes Vertebrae Upper Aguja Formation, Texas Carcharadon Hastalis Bakersfield, California 1 5/8 in or 4.3 cm Isurus Planus Bakersfield, California 3/4 in or 1.9 cm Various Pathological Shark Teeth Morocco Titanothere Jaw South Dakota Titanothere Vertebra South Dakota Unknown Vert (found in box marked South American Gar, definitely not that ) Tylosaur Vertebra Upper Cretaceous Tallahatta SE Alabama Massive Phytosaur Vertebra Quay County New Mexico Unknown Mosasaur Premax Tegana Formation, Morocco Partial Unknown (Platecarpus relative?) Mosasaur Skull in Plaster Most of the upper section of the skull, eye socket is partially visible. Very very strange teeth. The guy had thought it was Platecarpus, but he said the teeth were likely too short. Chunk-O-saurs Hell Creek South Dakota Ammonites As always, I’d love identifications on anything I don’t have IDs on. Hope you all have a great rest of your weekend, stay safe!

Hey all! I’ve got a piece I’ve been looking at and considering purchasing when I have the funds. It’s marked as a Mosasaur rear jaw section, and it’s not reading to me as such, but I still have an interest in bones from the area so I figured it was worth a shot having the experts look at it. I’m hoping to improve my fossil preparation skills and I’m interested in doing some restorative work on some less special pieces.

Howdy! I recently went to Post Oak creek, and ended up with more matrix than I can immediately use. Rather than let it sit unsearched, I figured it was worth a shot to post some up for trade here. Each bag has a pound of material in it, and they have proved to be very productive. I’ve found numerous ptychodus teeth, a (poorly preserved) lobster carapace, shark and fish vertebra, various bones, coprolites, and of course, lots of other shark teeth. So there’s lots of different things that can be found. I’ve got around 25-30 lbs I’d be willing to trade. I am primarily interested in vertebrate material, but I’ll also look at ammonites, and really anything else since I’ve finally gotten back into collecting again.

How many Myllokunmingia specimens are known to science? I keep on seeing wildly varying numbers, ranging from 1 to close to 100, and I really want to get a straight answer.
