Kimberly C Posted April 20, 2019 Share Posted April 20, 2019 Hello, I find a lot of what I believe to be marine fossils from the Cretaceous period on my land up in Grayson County, North Texas, but I am not certain what kind of fossils they are. Here are pictures of what I think are coprolites? Thank you in advance for your help in identification. Link to comment Share on other sites More sharing options...
DPS Ammonite Posted April 20, 2019 Share Posted April 20, 2019 Welcome to the Forum Kimberly. You have pieces of oysters and or bivalves in a Cretaceous rock that is sandstone or limestone. Take a look at this geology map to see if you can find out what formation they are from. Let us know what you find out. https://txpub.usgs.gov/txgeology/ A good source of info for north Texas fossils is: http://northtexasfossils.com/ Also, consider joining the Dallas Paleontology Society: https://www.dallaspaleo.org/ My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere. Link to comment Share on other sites More sharing options...
