This week I have an object that I found hiding in an unnumbered box during a reshuffle of the Horniman bone room (more about that later):
I managed to work out what it was and reunite it with other parts of the same specimen, which was very satisfying, but it took me four attempts where I checked against other specimens to get the correct identification. Do you think you can do better?
As always you can leave your questions, thoughts and suggestions in the comments box below. Good luck!
Zygoma 
Part of the Z.A. and skull. Last time we had one of these it was an elephant. Given the shortness of the Z.A., probably something with a short face (front to back). Primate?
Z.A. & skull is right and the face is shortish…
Has Peter put a pinnie on?
Very good!
This one is easy – to a point. This is the squamosal of a phocid seal. My library is not yet here, but odds are its a harbor seal or another phocine. The telltale sign is the massively inflated tympanic portion.
It’s about the right size for a harbor seal but that suture doesn’t match the shape from the harbor seals I see around my area (Alaska)
