While we walked round Buttermere yesterday Tom was enjoying some Welsh sunshine:
On what feels like the first proper day of winter, I went to Bracelet Bay via Mumbles. I was in search of oncolites and other Early Carboniferous fossils as well as Mediterranean gulls, which spend their winter in the bay, usually in good numbers.

| Prominent calcite crystals, with haematite veining, in faults in the Carboniferous limestone. |
 |
| Oncolites: fossils of cyanobacteria algae that form spheres, similar to stromatolites. |
 |
| A mixture of black-headed and Mediterranean gulls. |
