CRYSTALS & DINOSAURS | What Crystals Reveal About the Past

Hey, Ty. Yeah. Noticing some crystals out here. What's going on with these crystals? Uh, let's see. It's probably gypsum. There was a couple of spots where, man, they were just totally thick. Gypsson or selonite. So, is this something that you can find out here? It is. Yeah, they you find it a lot of places. So, it's a precipitant mineral. It uh means that the water that this deposit was in was salty brackish was uh like an estuary type thing that would have had a lot more salty brackish water in it. Okay. So these salt and these minerals would have prec precipitated out in the dirt and then they erode back out. So that what you're seeing inside those is actually the mud or moss or whatever it was that was in the ground when they dinosaurs were here. So this is a good indicator to look at and say, "Hey, there was we're we're near the coast. We're we're close to the close the tidal areas, things like that. Her backwater pools are very stagnant and brackish and dry up every year and stuff." Unfortunately, it doesn't help with the dinosaur preservation. It actually hurts. How so? So it's it because that sort of environment is very slow deposition. It doesn't bury them very fast and it's more acidic. So the bones didn't preserve as well. So you don't find as many good bones where you're finding the gypson. So this is an indicator that hey this is probably that layer is probably not have anything in
