Found 7 results

  1. I hit a new spot in Northeast Texas. This area is a mix or cretaceous and pleistocene. The rooted mosasaur tooth and my first croc tooth made my day. Both are super rare for this area. I also found the largest Enchodus jaw I've found since I started hunting four years ago.
  2. Beaver tooth or mammal claw NJ Cretaceous

    NJ Cretaceous streams, found a few of these over my time, just not sure what they are. Any advice? Sorry for crappy pics, if its an issue and a piece that's nto easily determinable I will take more exact close ups. Thanks all!
  3. I'm thinking beaver tooth??????

    Found in Peace River. I think maybe beaver??? or capybara??? or could be totally wrong about everything.
  4. bony trabeculae

    Are there species specific patterns for trabeculae ? If one has a tiny piece of bone, can one tell a mastodon from a beaver or a horse by the pattern or size of the spaces? Reptile, mammal, or dinosaur? what kind of clues on can get from bone chips?
  5. Castoroides

    http://www.researchgate.net/publication/268035498_Taxonomy_of_the_Pleistocene_giant_beaver_Castoroides_(Rodentia_Castoridae)_from_the_southeastern_United_States
  6. Was doing some fossil collecting today in the NJ cretaceous streams, when I found this beauty. I am pretty sure that it is an incisor of a giant beaver. I was coming back when I decided to double check a gravel bank and there it was.
  7. These are a few of the pdf files (and a few Microsoft Word documents) that I've accumulated in my web browsing. MOST of these are hyperlinked to their source. If you want one that is not hyperlinked or if the link isn't working, e-mail me at joegallo1954@gmail.com and I'll be happy to send it to you. Please note that this list will be updated continuously as I find more available resources. All of these files are freely available on the Internet so there should be no copyright issues.
