 My name is Dr. Kyron Prince and I'm a carbonate geologist. What that means is that I study carbonate deposits. So carbonate deposits are everywhere. Think of a reef, a coral reef for example. That's a pretty famous example of a carbonate deposit. Or if you ever walked along a beach and picked up a shell, chances are that shell was made of calcium carbonate. So this is a mineral that organisms frequently will use to build skeletons or hard parts in marine environments. And I come along afterwards and study those skeletons to determine what environment was like in the past. And it has great information about what ancient climate was like, what ocean conditions were like. And it's a really great tool for figuring out past environments, even those from millions of years ago. It's pretty cool if you ask me.
