Hey Pete. During one of my visits to Ridgemount Quarry, I found these. Each is less than 1mm.........Don't ask me how I even spotted this little cluster. Eurypterid eggs, spores, Silurian coprolites? Any ideas from anyone would be much appreciated. Thanks. Tom

Hey Tom: As you know there are many weird things in the Bertie Group... this one reminds me of poop or algae cluster ( just guessing) ... leaning towards fossil pooh. PL

We get pellets like this densely packed into burrows in the Afon Gam - in that case, we're going with the name Tomaculum, although that's a form genus and anything could be making it. Because they're rounded, you can rule out arthropod, which is a start. In our case they're associated with organic burrow linings that were almost certainly from ecdysozoan worms - either priapulids or palaeoscolecids, most likely. As the group is quite diverse, and in your case it's not in a burrow (at least, not any more - may have been reworked), pinning down a phylum is going to be tricky. Priapulid might be most likely, though, going by the size and age (nematodes and nemerteans, for example, should be much narrower). Well, it's a start.
