Thundereggs from the UK
The UK is not known for thundereggs. Indeed, for a long time I and much of the thunderegg world was convinced that there was none here at all. The following thundereggs are locations I found myself and, while they are known to geologists, I believe this is the first time they have been presented to the rock-hounding scene. These are ancient thundereggs - older than those in Germany and far older than the USA ones. This explains why they are so decayed and weathered.
