Fab Abs? Ancient Fossil Fish Had Em!

Palaeontologists have discovered an ancient fossil fish that shows surprising signs of having abdominal muscles, previously thought to have only developed in land animals.


apping the oldest fossilized vertebrate muscles ever seen — in Gogo fish thought to be 380 million years old — researchers worked out the position of the muscles and the orientation of the muscle fibers.

The fossil fish, found in the Kimberley region of Western Australia, are enclosed in limestone nodules and are known for their exceptional preservation.

"The muscles in the abdomen cavity that we found weren't expected because even in living fish their main mode of propulsion is of course to flap their tails to left and right so all the muscles are sitting on the side of the body," said Gavin Young from Australian National University's Research School of Earth Sciences.
