This is one of the few 'neighbors' of the famous Lierbachtal thundereggs - and looking at it, you can see the similarities! It is hard to judge from three specimens, especially given how varied this patch of ground seems to be, but it does seem to have a certain aesthetic of it's own though - notably a much warmer coloured matrix verging on yellow-brown.
