Census of Marine Life: new species and human impacts
The Census of Marine Life (COML) has just discovered a multitude of new deep-ocean species, proven the overfishing of 90% of the top of the ocean food chain, and traced human impacts back to the time of Christ.
One of the creatures, an Asian sea worm, is the kissing cousin of a fossil, hallucigenia, from the Burgess Shale.
The first time geologists reconstructed hallucigenia, they got it upside down. Read the story in Stephen Jay Gould's Wonderful Life (1989).

Wikipedia on the Burgess Shale, maps and mountain views by geologist Stephen Earle, and artists' reconstruction of the fossils, 520 million years old.
