Large fish skull (profile) and post cranial bones from an extinct predatory fish , on matrix, 40 1/2” wide and 24 1/2” tall. Skull measures 34” long and 19” tall. Lower jaw measures 12 1/2” long. Approximate weight is 45 pounds. Estimated length of entire fish would have been approximately twelve (12) feet.
Skull is three-dimensional and has substantial depth and relief (lots of peaks, valleys, and ridges). There are a total of thirty-six (36) teeth of various sizes (most are in EXCELLENT condition), plus fourteen (14) cervical and dorsal vertebrae with ribs.
The largest tooth is 1 3/4” long. The cranial crest is present and articulated. All skeletal elements exhibit superb texture and detail. Trauma (disarticulated vertebrae and ribs) in the posterior area of the skull indicates that sharks and other scavengers most likely ate the body of the fish.
This is an exciting and striking display fossil of the largest fish species (except sharks) that ever roamed the prehistoric Cretaceous seaway! Specimen has mounting hardware installed on the back side and is 100% ready for a wall mount. Spectacular exhibit or decorator fossil!
