This week I have a bit of break from the norm. Rather than giving you a specimen from the Horniman to identify, I have a couple of guest mystery objects from Cyler Conrad for you to attempt.
These two bones were uncovered in an archaeological site in San Francisco, California, USA and they are proving hard to identify. Any idea what they might be from?
As always, you can put your comments and suggestions below, but please also feel free to engage in discussion about these objects – let’s see what emerges!
