Jellyfish Fossils

Researchers just published their discovery of four types of well-preserved fossil jellyfish in the open-access journal PLoS ONE (go Bora). The jellies are from about a half a billion years ago and not much seems to have changed in their physiology. Utah, of course, is no longer under the sea. See if you prefer this image from the journal:
