After the Lord has a little introductory chat with Job He jumps right in and states;
Chap 40; "Look at the behemoth, which I made along with you and which feeds on grass like an ox. 16 What strength he has in his loins, what power in the muscles of his belly! 17 His tail sways like a cedar; A Brontosaur?
Chap 41; "Can you pull in the leviathan with a fishhook or tie down his tongue with a rope? Can you fill his hide with harpoons or his head with fishing spears? 8 If you lay a hand on him, you will remember the struggle and never do it again! 9 Any hope of subduing him is false; the mere sight of him is overpowering.
There is a U-boat log signed off by all present on the bridge where a Kronosaur like creature did a tail dance after they torpedoed a freighter. Not a good spot for a dip don't you think?
For centuries ship crews have documented creatures like these, as have a number of terrestrial sources.
I am in no sad state at all. I have been blessed and encouraged to chase down this stuff all these years and watch the other side fall apart time and again. God has allow me to work in places where this evidence actually is Vs cutting and snipping from weblinks following someone else's lead to nowhere.
But you can really tell because it's tail.
