NOTE” PREDATORY FISH HIGH IN THE FOOD CHAIN REPRODUCE IN SMALLER NUMBERS THEN THE FISH THEY ATE. THIS EXPLAINS WHY SOME FOSSIL TYPES SUCH AS PHAREODUS ARE FOUND INFREQUENTLY . OTHER INSTANCES OF RARITY HOWEVER ARE NOT SO EASILY EXPLAINED.

PHAREODUS A LARGE LOOKS POWERFUL WITH A ROBUST BODY WITH LARGE FINS AND STRONG JAWS AND A SET NUMEROUS TEETH. THIS FISH CAN REACH 91 CM OR 3 FEET IN LONG. THEY ARE HIGH ON THE FOOD CHAIN,THEY ARE NOT ABUNDANT AS FOSSIL ARE CONCERNED. SPECIMENS FOUND IN A DIGGING SEASON ARE CAN BE COUNTED ON ONE HAND AND SMALL SPECIMENS ARE MORE RARE. THE MAJORITY OF THIS SPECIES ARE DAMAGED BEFORE FOSSILIZATION .A COMPLETE UNDAMAGED PHAREODUS IS A TREASURE AND WAS A PRIMARY PREDATOR.

SNote: Seasonally some 58 million years ago, in the Green river region of Wyoming, torrential rains would occur in the mountains. The rain would flow down the mountain sides and then wide shallow lakes would form in the valley below. When the dry season would occur these lakes would dry up due to evaporation (similar to certain parts of Africa today). Millions of fish would die in this short period of time. This climatic cycle happened over a 20 thousand year period. Layer upon layer of mud was deposited over these years entombing all these fish. At a much later date volcanic activity uplifted this area to expose all those layers of fossil fish.
