I am now back in Szczecin, and back to work among my silicoflagellates. To start off the second half of my Fulbright photo-blog, I have here a very rare silicoflagellate: perhaps the oldest known double skeleton. This is Vallacerta hannai, and comes from the Cretaceous of Russia. The specimen was found by David Harwood, but I was sitting next to him when he found it.
