Friday mystery object #67

Here’s a specimen without any identification from the Horniman’s collections. I thought I knew what it was straight-away, but then had to spend ages trying to confirm the identification. I just hope you all come to the same conclusion as I did!

As usual, put your questions, observations and suggestions in the comments section below and I’ll do my best to reply during the day. Good luck!

    • To the best of my knowledge (I took this photo a good few weeks ago) the skull is pretty much complete. I don’t think that turtles have a solid wall behind the eye-sockets like primates – their braincase isn’t that big and an open robust skull structure will help with equalising pressure during a dive.

      • OK, so I’m looking through the skull. Turtle then. But which sort. Not a Loggerhead, the skull’s the wrong shape. Is it an adult?

        “Equalising pressure during a dive”- sea turtle then, rather than a terrapin, etc?

      • I have no idea. The frontal view makes it hard to see what shape the beak is, but the nasal opening looks too small for everything species I’ve seen so far. There’s only seven to choose from, it shouldn’t be this difficult.


  1. Skullsunlimited has four sea turtle skulls. I think it is a Olive Ridley Sea Turtle or a Green Sea Turtle but if I had to choose one I think it is most like a Green Sea Turtle because the other one has an extra bit of bone on the edge of the eye bit.
