Huge 12.5 Inch Long 50 Million Year Old Trout. Mioplosus labracoides was an extinct relative of modern day trout. It is over 50 million years old from the famous Green River Formation near Kemmerer, Wyoming. Mioplosus was a predatory fish that had two dorsal fins and a fan-like tail. This huge 12.5 inch long fossil is one of the largest found for this species and is virtually complete with excellent detail in the head, body and fins. The 3.5 inch head is a beautiful very dark brown color even with sharp little teeth in both the upper and lower jaws. The rest of the body is a lighter chocolate brown color with complete vertebrae and spines with just the tips of some of the delicate spines restored. The 18 x 7.5 inch limestone matrix has been backed with wood and even has a hook for hanging if so desired. Small fish are common from the Green River formation but large fish such as this Mioplosus are in great demand from both collectors and interior decorators for hanging on the wall.
