Ima Surchin Posted September 19, 2021 Author Share Posted September 19, 2021 So it isn't possible it went through a petrification? Link to comment Share on other sites More sharing options...
Mainefossils Posted September 19, 2021 Share Posted September 19, 2021 @Ima Surchin, it is highly unlikely that this rock is an example of petrified remains. Soft body preservation is an extremely rare occurrence, the link shown describes this type of preservation for dinosaurs, https://online.ucpress.edu/abt/article/83/5/298/117017/Preservation-of-Soft-Tissues-in-Dinosaur. The likelihood for this to be such an instance is extremely low, especially in an area where such finds have not been seen before. You are in an excellent place for fossils! Do you have access to some geology maps and papers on your area? Research and patience are two of the best tools of a paleontologist, some luck also helps. Happy Hunting! 1 1 The more I learn, the more I find that I know nothing. Regards, Asher Link to comment Share on other sites More sharing options...

Ima Surchin Posted September 19, 2021 Author Share Posted September 19, 2021 Thank you! Yeah it looks like it was right on a coat line during the Cretaceous period. Definitely under or near water. And I do have some turtle remnants, they just gotta be. I'll post them when I clean them. This property has belonged to my best friend's family for years, without digging for things. We're now doing it! Link to comment Share on other sites More sharing options...

As a fellow Texan, I and others here would celebrate any turtle fossils you found. By the same token, we hope you learn that many rocks can manifest strange, natural features. 4 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
Brandy Cole Posted September 20, 2021 Share Posted September 20, 2021 When I first started fossil hunting, I was very unsure what turtle fossils may look like, and it helped me to see examples from other people on this forum. Turtle shells are hard material, and it's pretty common to find them even if you don't find bones. At least where I am in southeast Texas, fossilized shell fragments are one of the most common things I find. I'm including pictures of an example below. The first key thing to look for is an almost spongey looking filling. This is osteoporosity, and it should be pretty obvious in both shell and bone (if they're broken, which is very common). It helps you tell the difference between a real fossil and a rock, since you generally won't see anything resembling that texture in most rocks. In terms of determining whether it's a bone fragment or a turtle shell, it helps to look for the kind of suture or seam-looking lines that naturally divide up the turtle shells. I've included an example where I circled the spongey looking section I'm taking about in blue and the suture lines in red. Good luck to you! --Brandy 2 Link to comment Share on other sites More sharing options...
