This week I have a guest mystery object for you, from the collection of Andy Taylor FLS FBNA – a regular contributor of specimens to the blog, and this year a fellow attendee of the Natural Sciences Collections Association conference, which is taking place in Machester at the moment – but more about that when I come to the answer next week.
For now, here’s the object:
Let me know if you can figure out what it is – I appreciate that the photography of the specimen makes this a bit more of a challenge, so you may need to dive deep to work it out. Have fun!
Zygoma 
Should I be having frites and a fresh glass of water with this?
in a very broad sense
Thanks for the diving hint! Can bivalves open under pressure?
You’re heading along the right lines
What a cool (cold even) bivalve.
It’s like a horse mussel, only really deep. Going further i’d guess the species might be something like child’s play.
A really great effort – correct genus; wrong species 👌
OK, so maybe not so cool afterall, perhaps instead a lover of heat?
Quite possibly
