A Canadian Lagerstaette that's not the Burgess Shale

Scientists writing in the latest issue of Geology report on a newly identified Lagerstaette in Alberta, Canada, not far from Banff. The Ya Ha Tinda site records a marine ecosystem from the early Jurassic, around 183 million years ago. Here is a short description of the findings. But check out the original paper (the first link above) for nice images of the fossils.

The Bears Ears, and what it means for paleontology

Fossilized dinosaur brain tissue found

The Geological Society of London has released a Special Publication announcing the discovery of fossilized brain tissue in an ornithischian dinosaur. It is unclear whether or not this tissue served as the seat of the dinosaur's soul, but we're sure that a Descartes scholar is bound to look into the issue soon.
