Please help identify these items or help verify if they are even fossils
Maneralization posted a topic in Fossil ID
Hello. I am new here and I have quite a few specimens that I believe to be teeth or claws, that appear to have fossilized from a mineralization or petrification process, but I could certainly be wrong. These have all been collected from SW Missouri. Any help would be greatly appreciated. -
There are a lot of submissions to identify dinosaur material and a good number do not have enough information or its the wrong type of to assist in identification. Some posts are great. So I've prepared this for what I'm looking to help in this process. What is needed: An accurate provenance is the most important item required to obtain an ID. 1) USA & Canada Formation State or Province County or Nearest Town (a MUST) 2) Other localities Country Formation Nearest Town, Area 3) On Jurassic Theropod teeth I need measurements and serration density shown in the illustration (CH, CBL, CBW and Density). With Cretaceous teeth just need Crown Height - measured from the distal base to tip. If more is required I will ask. For herbivores All I need is CH. 4) Photos Tim @Fossildude19 always post this image to get the best overall photos. Additional requriements: Photos need to be sharp and HD. Out of focus images are useless Avoid holding anything, use some support like the putty (what I use - Fun-Tak) or plastic holders. Tak is just a temporary support not good long term and don't press hard No HANDS I do not want to see fingers in any photos. Your hands shake and fingers hide some of the specimen. There are a few exceptions when photographing the base of the tooth or articulation surface of a claw. No OBTUSE photos unless asked for. All straight in shots On Theropod Teeth these are examples of the ONLY 4 photos needed to start. With herbivore teeth I just need one image of both sides. Both Sides Base Mesial Carina May require an angle view to see distal characteristics like texture, undulations, blood grooves BUT not needed at first. I may require a close up of the serrations to see the shape of the denticles. If you plan to be a long term collector I do recommend purchasing a Digital USB microscope. They are relatively inexpensive and go a long way to help in identification. Otherwise sharp HD closeup photos would be needed. Not needed initially. For Claws I just need 5 photos, straight in shots, no obtuse angles. Length measurement Examples of all sides needed and measurement (red line) - I use putty under the claw to make it square to the camera lens For Phalanges need views from all sides Reminder just because all the information is provided it does not guarantee an ID especially from material outside of the US and Canada.
