Large fish skull (profile) and post cranial bones from an extinct predatory fish, on matrix, 32" x 32.5". Skull measures 26.5" long and 21.5" tall. Lower jaw measures 10.5" long. Approximate weight is 30 pounds. Estimated length of entire fish would have been approximately 10 feet. Skull is 3-dimensional and has substantial depth and relief (lots of peaks, valleys and ridges). There are a total of 24 teeth of various sizes (most are in excellent condition), plus 8 cervical vertebrae and a partial pectoral fin. The largest tooth is 1.75" long. The cranial crest is present and articulated; all cranial elements exhibit superb texture and detail. Trauma in the area around the skull indicates that sharks and other scavengers most likely devoured the body of the fish, as evidenced by the vertical protrusion of a portion of the pectoral fin out of the top of the skull. Several of the cervical vertebrae are also disarticulated and scattered; plus, two of the gill plates were torn from the skull and deposited below and to the right of the lower jaw. Specimen is an exciting and striking display fossil of the largest fish species (except sharks) that ever roamed the prehistoric Cretaceous seaway! A mounting cable has been installed on the back side, making it 100% ready for a wall mount. UNIQUE decorator fossil!
