Hi Don, a nice dendrite plate!
But please change the locality: SONThofen is a town in the Alps and the southernmost city in Germany. The famous fossil locality where your dendrites are from is 200 km north of it in the middle of Bavaria and the name is SOLNhofen ;-)
Full name of the locality is: Limestone quarries, Solnhofen, Middle Franconia, Bavaria, Germany. Please change it, thanks!
Regards
Tobi
