This devil's toenail, or Gryphea,
used to recline like a shelly armchair on Warwickshire's sea bed.
Devil's toenails get a bad name
from their appearance. Thankfully they have more in common with
today's oysters than with the smelliest pair of prehistoric feet!
The picture shows a devil's toenail
found at Stretton-on-Fosse.
