Germany
In the following you will find the sources of thundereggs from Germany I have in my collection.
This page deals with Bavaria, Lower Saxony and Saarland, cause the amount of sites is not that great. The locations of Baden-Wurttemberg, North Rhine-Westfalia, Saxony and Thuringia are on seperat pages.

Bavaria
Kornberg
The sources of Kornberg, Lenau and Unterwappenöst are located in the Oberpfalz not far east of Kulmbach. These are quite rare materials of lithophysae agates often showing veins or vein like fillings in eggs or jasper and agate veins in rhyolite.
Lenau
The vein jaspers of Lenau are quite famous like that dog-teeth sample. They usually formed in rhyolite.
Sailauf
The quarries of Rehberg and Hartkoppe near Sailauf are the best known locations for thundereggs in Bavaria. The quarries are located near Aschaffenburg and closed for collecting. Sometimes one can find ancient material.

Unterwappenöst
The Unterwappenöst material is the only of my collection of those three locations with a real shaped thunderegg (#1). It's quite rare material and mostly known as the source Aign.
Lower Saxony
Ravensberg
In Lower Saxony, next to the boarder to Thuringia, there are a few locations of thundereggs near the city of Bad Sachsa. They can get very big (up to 600-800 mm), but not so nice filled in that size range.
Those here are from the location of Ravensburg (#1) and Ravensburg - Tennisplatz (#2-4).
Saarland
Leistberg (aka. Oberthal)
The, I would call it, ancient location of the Teufelskanzel near Oberthal in the Saarland is the only source of thundereggs in the Saar-Nahe-Complex (Permo-Carbonian). The Teufelskanzel (devils pulpit) is a rock formation and nowadays closed as a natural reserve with a strict prohibition for collecting there.
But there are another location near by which is not in the wilderness area - Güdesweiler or Rötelpfad (new name).
Güdesweiler / Rötelpfad
Those eggs below are from the location of Güdesweiler or Rötelpfad - an old nearly forgotten place re-discovered in the last years. They are more weathered so that the gros of them has a white matrix. The old finds tend to be larger, the new ones are smaller.
Teufelskanzel
The Teufelskanzel specimens, as shown below, are more dark in matrix and show a greater variety of colors in the filling. Moss, plume and pseudos are rarely seen but divers crystals occur quite often.
