Hello All I've come across a few desiccated specimens from a possible prehistoric pit in central England. We had thought they might be acorns, but on a closer look I'm not sure about the structure. Any suggestions would be very gratefully received. Apologies for the quality of the photos - I just dashed them off on my phone! Thank you, Karen Stewart. <https://mail.google.com/mail/u/0/?ui=2&ik=09684cf15e&view=att&th=147f39be51d72e6a&attid=0.1&disp=safe&realattid=f_hz2p34qk0&zw>
