Pyrite dimples with fossilised wood

Recommended Posts

Another find from Saltwick Bay, this time very recent. I'm guessing that the main chunk is fossilised wood of some sort, but I'm stumped by the small (~1cm diameter) patch of pyrite that exhibits very regular dimples (see images 1 & 2). Any ideas?

This looks like an encrusting bryozoan of some sort.

Very interesting! I've seen one or two like this before in other people's collections from there and none of us have been able to identify it.
(The main piece is indeed wood.)
