Gastric Stone

[fig rocks]

I was told this is a gastric stone from a dino gut! How would they know?

Unless they found it inside the gut of a dinosaur when they were digging it out I have no idea. It does sound better than "this is a shiny rock"

Ro,

For gastoliths, the texture of the surface is described as "greasy" or "like silk" as opposed to tumbled or river polished. It has to do with the way stomach acid etches the stone rather than what man made polishes or natural tumbling do.

Yup, that describes the texture exactly, thanks Don!

That's cool, I've often wondered the same thing. Now I know.
