The next months I will build a website about lithophysae, thundereggs, Porhyrkugeln or as I put it: Framed agates!
Found during the works on the gaspipeline, just east of St.Egidien. Some have very thin lens shaped cavities. Also stunning colorful eggs were found here, maybe the best in Saxony. Till now …. 😉 But the ones in this gallery are nice examples too.
