Barring an elaborate hoax, this could be one of the biggest fish stories of recent memory. From the NYTimes:
Scientists have discovered fossils of a 375 million-year-old fish, a large scaly creature not seen before, that they say is a long-sought “missing link” in the evolution of some fishes from water to a life walking on four limbs on land. You have GOT to see the photo. Wacky.
