Stuff You Should Know
Short Stuff: Trovants

That's right. When they started getting serious and we're like, guys, can we move past alien pods and dinosaur eggs and really try and figure this out?

Well, probably so, because that's where all that stuff takes place. But when they finally got serious, they were like, you know what's going on here? This is a concretion.

And a concretion is something that starts out as a little pebble or something or a leaf maybe, and then starts getting depositions, maybe sandstone, other kinds of grit and minerals washed along a river, just building up and sort of cementing, almost like a snowball rolling downhill. That is a concretion.

And they all got busy. So they, in Oslo, they hypothesize that the minerals were carried by a prehistoric river along these little sandy sediments and formed kind of a slurry solution, like you said, of mainly calcium carbonate. Along with calcium carbonate, you can also get sandstone from iron oxide and quartz. But in this case, the sandstone is calcium carbonate.

So another little oddity here we have to talk about is the fact that these things secrete cement. And this is sort of what lends people to think like these things are alive. It's after a big rain. They will absorb the minerals from that rain. And then those minerals come in contact with the chemicals that are already in that stone, that calcium carbonate and the other stuff.
