Today I wrote an extremely teensy story for ScienceNOW. It’s at the bottom of this list. It’s about a 300-million-year-old fossil brain. That’s really old. Soft tissue doesn’t usually get preserved, but they found this one with the crazy bright x-rays of a synchrotron.
Those little teeny stories only run with one picture, so I’m really just blogging here to share this drawing of what the iniopterygian (it’s a cartilaginous fish, related to sharks and stuff) might have looked like:

Is it just me, or does this fish look…well…kind of dumb? In a wide-eyed, hopeful way. Sorry bout the extinction, little guy.
