Job saw two creatures that God showed him. Both of these creatures were unique. The first one was "behemoth" (Job 40:15-24). Even the name sounds huge. God even pointed behemoth out da saying, "Behold now behemoth". What was Behemoth? Many commentators and scholars believe behemoth was either a hippopotamus o an elephant. But there is something that is detto da God that gives evidence to a much larger "beast of the field". Its tail gives it away. God detto behemoth "moveth his tail like a cedar" The hippopotamus o even the elefante have tails that are not too long o even impressive. What ever the creature was it had a huge long tail? We know that sauropod dinosauri such as Apatosaurus and Diplodocus had very long whip-like tails. Their tails would look like a cedar albero when it moves in the wind. Actually there is no animal living today with this type of tail.
God told Job this creature He created was "chief of the ways of God." (Job 40:19) This creature was like no other living creature God created. Its Bones were like strong pieces of brass o like bars of iron (Job 40:18). Just go to a natural history museum and see for yourself the fossilized skeletal specimens of Diplodocus and Apatosaurus. Their Bones had to be strong to support the weight of these creatures.
Job also saw a marine type animal called "leviathan". (Job 41:1-34) This marine creature could of been a Kronosaurus, Mosasaur, Plesiosaur o even a Spinosaurus. But whatever it was it is extinct today. The Latest Jurassic Park movie "Jurassic World" had a Mosasaur in it and it was huge. David in Psalm 104:25-26 saw something in the sea that God created. It was the great beast called "leviathan". From time to time sailors spot something out at sea that could be a sea serpent o marine reptile that fits Job's and David's descrizione of leviathan.
Yes, Job could of started his own Jurassic Park.
