Pycnodont fish teeth from Ketton Quarry

By March 24, 2019News

Below and above with scale is a fine example of what I believe to be a partial jaw from an extinct species of pycnodont fish called Eomesodon cf. trigonus or Gyrodus sp found by one of our members on a recent trip to Ketton Quarry.
Our members have found single teeth from this fish from previous visits to Ketton Quarry, but this find is a first for the society as far as I’m aware.

Below are some comparison examples which are also from the Bathonian stage (Jaws of Gyrodus sp. and Eomesodon cf. trigonus).

Top: Prearticular (splenial) of Gyrodus cuvieri (Natural History Museum, London).
Bottom: Prearticular (splenial) of Eomesodon cf. trigonus (Department of Geology, University of Leicester).

The specimen is now in the hands of society member Richard Forrest going through a rather tricky prepping process.
