  2. Everyone should know about this!

    Just too COOL!
  3. Canyon Lake odd balls - Texas Cretaceous

    I agree with JohnJ they are mineral concretions. I think they may be a type of gypsum crystal with an originally pentagonal structure. I have been fooled by the shape as well. The little discs are Orbitolina texana forams (Foramnifera) and an index fossil for most of the Glen Rose. Forams are amazing in being single-celled organisms of "immense" size. Most of the Glen Rose was deposited in fairly shallow waters. imagine shallow salty lagoons. Salts grew forming, layers rich in anhydrite such as gypsum. Later ground water, over all those millions of years, flowed thru those layers disolving the salts and the resulting cavities collapsed. When you read the lithologic descriptions of these formations they call them solution collapse zones.
  4. i search woodbine and then i search the fossils found in that area - unnamed theropods was one of them - when i search that i look at all the different classifications of animals and i see this - Coelophysis bauri - with this description.... "numerous complete to disarticulated skeletons in reddish-colored fluvial siltstones" using this animal as an example of the colors in my rock....i cant help but put my fossil as part of the rear knees. any chance of that? unfortunately this animal comes from the new mexico area but i now have a colorful concept of how some of these fossils can look....other than brown. another animal - the protohadros - similar in body structure....and, again....im drawn to the rear legs. here is a tibia from the protohadros found about an hour from denton, in arlington - arlington archosaur site (AAS) in 2003.
  5. Trimerorhachis skull?

    Not a skull, unfortunately. This looks like it has some cross sectioned gastropods in it. Maybe limestone, with a bit of rudist or other sea fossils in it? Definitely not bone material, however.
  6. Fossil ID

    Welcome to the Forum. Looks like a quartz or quartzite pebble with some mineral inclusions, ... to me. Sorry, ... but I am not seeing a fossil. Keep looking though.
  7. Ray teeth?

  8. Trimerorhachis skull?

    I found this in west Texas, in the Red Bed area. I was wondering if it could be an amphibian skull fossil of some kind. Maybe a trimerorhachis? I'm still learning about the extinct amphibians and reptiles in my state. Any suggestions are welcome!
  9. Tiny theropod tooth ID

    OK, now that was a most informative thread. Thanks. And great score! What an interesting creature, the Dakotaraptor! Cheers.
  10. Penn Dixie 2019 Dig With the Experts

    Membership acquired! Dumped an extra $10 on the non-members weekend pass, but $30 is still very reasonable!!
  11. Fossil ID

    Welcome to the forum! Unfortunately, I am not seeing any sort of fossil here...sorry. Regards.
  12. Fossil ID

    Found this 20 years ago. have packed it around always wonder what it is ..found 20 miles due West of Ellensburg Wa ..I see the head of something looking from left to right . opposite in picture .the head is almost the size of the rock .the white mass is center of it's mouth and eye is located just above that ..there appears to be scales of some kind on the back of it and a patch of green on the bottom. It is all coiled up hope the pictures I have are good enough to ID it ...it is roughly the size of a good potatoe ..
  13. Tiny theropod tooth ID

    Do you think it is from a juvenile specimen?
  14. Tiny theropod tooth ID

    Absolutely awesome news! Thank you so much for all your help!!! Cheers!
  15. i will do just that - thank you very much !
  16. Just a short video of a quick trip to the beach last week to enjoy the spring sunshine!
  17. Today
  18. I'm fairly certain this is not an eroded mosasaur vertebra. I would research other vertebrates in the Woodbine Formation.
  19. Last Minute Fossil Hunt! Found Delphinodon!

    Serves him right for wearing new clothes. You could get back on his good side by mounting this tooth as a pendant and wearing it on a necklace (outside of your shirt) on all future fossil hunts with Cris. Cheers. -Ken
  20. i need to change the resolution on my camera.
  21. Perhaps someone who isn't color blind should take this one.
  22. i agree and thats interesting - i need to quit thinking this thing died on land...it sank and some bottom feeders ate the flesh and those worm eel-like things (hagfish) came and ate into the knuckle areas and gnawed the thing to the core - thats a great mental image. much different than the tool i thought that could have made those marks....chopping the limb from the rest of the carcass or removing the flesh from this particular part of the animal. so perhaps its erosion or perhaps its a bottom feeder sucking the thing down to the marrow - thats great! am i wrong to say this is a "colorful" fossil? is it like this due to fossilization underwater? am i wrong to handle it? am i wrong to think this is a great specimen? it does make a great paperweight !
  23. Coprolite Hardness

    That would all depend on what mineral(s) they were replaced with.
  24. Everyone should know about this!

  25. Coprolite Hardness

    I was recently given some coprolite to polish for a friend. I was wondering if anyone knows what the general hardness would be as it relates to Mohs scale. Thank you
