Lithodomous

li·​thod·​o·​mous

Adjective

Burrowing in rock

Come on, seriously, other than a crossword puzzle no one is going to use this one, are they?

I was just happy to find two in a row that did not come from Latin.  Nope, we cobbled this one out of the Greek word  lithodomos, meaning mason and adding our own “ous” on the end of it.
