I was planning to give you a rest from Lierbachtal thundereggs, honest! But I just cut this today and I couldn’t resist sharing it, it is such a strange one. I have NO IDEA what is going on inside it! Lierbachtals are a weird stone that often leaves me confused, but in this case that massive curved stream of orange stretching right across the core takes it to a new level still. Lierbachtals are relatively prone to pseudomorphs and that is definitely involved here in this stone, but more than that, I am honestly not sure. I have never seen anything quite like it. It looks like – I dunno, a tendon or something!
If anyone has some interesting info on how these insane structures formed, I would be very interested to hear it!
Edit: Here’s the other half!
