I distributed an email with a pic a couple of weeks ago about a possible mineral coated fruit that I could not identify. At the time I wasn't certain if it was a metal object, but we have x-rayed it and it really looks like a fruit with multiple seeds inside. Now I am not certain if it is a subfossil mineral coated/replaced fruit or an actual fossil fruit, any idea? I've found a few publications of fossils from the London clay that are vaguely similar. As to ID, assuming it is a Holocene plant remain, I've ruled out the Tilia, Fraxinus and possibly Commiphora possibilities (due to size, different numbers of ridges, different number of seeds....). Any further suggestions are welcome.

Thanks for the help!
