Need help identifying please


Recommended Posts

Its a vesicular (fancy geo word for hole(s)) Rhyolite (extrusive volcanic rock).  The holes were created by escaping gases as the lava cooled, then infilled by Quartz at a later date, creating the small white "pearls" seen in the sample.

I did soak it in vinegar for several days to clean it up. It looks to me like they have crinoids in it. Thanks for the reply I’m in the desert of AZ so their are so many cool rocks to be found. 

Upon looking closer, it does appear you have fossiliferous limestone.
