Dec 2023 - I am moving the website to a new server it will take time to get all the photos uploaded. I am also reformatting the pages to work better with smart phones and also enlarging many photos.
About:
Welcome to my website documenting some of the paleontological fauna of the North-central Texas region. Here you will find pictures of fossils mostly collected by myself with a few from others. I am currently accepting good quality photographs of fossils not already on the website. If you see an ID that is incorrect or incomplete please let me know. Some IDs are very general because of lack of time for in-depth researching. I can't give out specific hunting sites because I get asked frequently. This website is an educational, non-commercial project. I don't buy, sell or trade fossils. Enjoy!
I would like to thank photo contributors Roz M, Barry A, Mike O, Tera S, Wes K, Kerry K, W Knight, Frank H, Roger F, Ted L, Adam A, Robert R, and Sterling Z.
Texas:
The surface geology of the North Texas region is mainly limestone, shale, clay and sandstone that was deposited during the middle portion of the Cretaceous Period (110-90 million years ago locally). During most of the Cretaceous Texas was covered with a shallow to moderate depth sea that extended at times from Canada to the Gulf so the fossils will be of marine animals and plant life. There WERE brief periods when the sea level was low enough that dry land was exposed and the dinosaurs roamed. Areas to the west are "Pennsylvanian" age (300 mya) and "Permian" age (280 mya) further west.
