Hi everyone,
Two days ago, I went to Yaxley lake in Cambridgeshire (UK) and I found a handful of ammonites and belemnites. However, buried in the Oxford Clay with those ammonites and belemnites, I found this odd looking pebble which I was not able to identify (I am only able to tell obvious ones like ammonites, belemnites, bivalve, gastropod etc...). Before I decide to throw this away, I just wanted to ask you all whether this is something worth keeping for or just another random pebble. Any help you could offer would be greatly appreciated. I can upload more pictures if you need so please let me know.
Cheers,
Bong
