Naw. A paleantologist friend tells me this was an acrocanthasaurus, or something like that, that lived on my place 110 million years ago. I'll have to take his word for it since I'm not quite that old. Mud infilled the track and it solidified into a thin piece of limestone. I flipped it up with the backhoe and left the teeth mark on the left side. That was a shame. I would have used a rock bar to lift it had I known what was on bottom. That dude had one heck of a set of claws on him. No telling what you'll find when you get to digging fence posts in this country.
