Closeup of mosasaur bone. This specimen has mineralized in such a way that the crystals form in planes, so that they reflect light at a given angle creating a glassy flash. This phenomenon is not captured in the photo. -

I found this very small mosasaur bone (part of the paddle I assume), and it has a very small hole towards the top. This was found in the Cretaceous North Sulphur River of Ladonia, Texas. There have been a few discussions on other forums whether this is a natural or man-mad occurance. Has anyone else here ever found a mosasaur vertebrae or bone that has a near perfect hole in it? I’m very interested in how this occurred. Thank you for your input! -
Hey yall! These are a couple of items that were found in the North Sulfur River that I am uncertain about what they are. One appears to be bone, but has a rather porous and bubbly side and a flat and smooth other side. The other looks to be enamel, possibly from mastodon?? Thank you!
