Coelacanth fossil sheds light on fin-to-limb evolution

ottom of the sea floor.

Rather, these distinctive blue fish swim with their heads down, hovering just above the sea floor using an organ in their nose to detect living things in the mud.

It was astonishing luck that we found it, Friedman said, adding that the fossil had fallen off a cliff a couple of hundred feet high and landed in a different set of rocks. The four-inch long specimen details the fin of the animal, which the scientists approximate would have been about 18 to 24 long.

The scientists will return to the Wyoming site next summer to collect more samples.
