Just like any other rocks, they're going to break down over time, thanks to weathering and erosion. It was slightly higher Monthly Weather Review, Vol.
But once they're exposed, that's when they start to degrade. So it's kind of a double edged sword, because without the river, we wouldn't be able to see them. And then the river carves down through those layers and exposes the tracks. And for over a hundred million years, those were protected and preserved by those layers of sediment and rock. What protects these tracks? You know, they were laid down as a dinosaur walked on these muddy seashores and then within a few days or possibly a few weeks, sometime in the not too distant future from when they were put there, a flood covered it over with sediment.

And they walked through the limy muddy seashore on the edge of the Cretaceous Ocean that ran through what's now the United States."Almost all of Texas has been in drought since mid-Julycharacterized by widespread loss of pastures and crops as well as water shortagesSource: United States Drought Monitor"So the tracks that we're able to see are the ones that are in the most danger of being eroded away. So not a small it's not a small critter for sure. Interactive weather map allows you to pan and zoom to get unmatched weather details in your local neighborhood or half a world away from The Weather Channel. They were about seven tons or so and they were big.
But it was still a pretty large, a large creature.
