Even if people had seen dinosaur bones, nobody thought of putting
them together until near the end of the 19th century. There was no
way of looking at the bones and seeing this:

Where do you get that the Hebrews and ME people didn't see them?
Behemoth and Leviathan in the bible are dinosaurs. It also mentions
dragons in several places, and not as allegories. Some others here:

It may take several posts to answer these misconceptions but here's a start.
"Behemoth" as used in the Bible is most likely a hippopatamus.
<< Behemoth or "colossal beast," possibly the hippopatamus. The description given in Job 40: 15 suggests that this was a creature of the Nile and other great river valleys. Job uses him to indicate the amazing creative powers of God. >>
--Harper's Bible Dictionary, 1973
Even if you want to quibble about what "behemoth" is, it is clearly a massive animal, as described in Job, hence the name. It is a vegetarian, not a meat eater. It clearly lives in rivers and marshes. It is not fully a land animal. It is not a predator, and not a fast moving animal.
Always adopt the simplest theory that fits the facts. Start with things that we know exist, with animals that we know were around during recorded history. Try the hippopatamus.
Even if you stretch the behemoth animal in Job to be a dinosaur, it still gives us no reason to think any any similar animal was feared as a predator, or moved swiftly on land. Dinosaurs laid eggs. Job doesn't say anything about Behemoth laying eggs or hatching from eggs.

Look at Behemoth,
which I made along with you
and which feeds on grass like an ox.
16 What strength it has in its loins,
what power in the muscles of its belly!
17 Its tail sways like a cedar;
the sinews of its thighs are close-knit.
18 Its bones are tubes of bronze,
its limbs like rods of iron.
19 It ranks first among the works of God,
yet its Maker can approach it with his sword.
20 The hills bring it their produce,
and all the wild animals play nearby.
21 Under the lotus plants it lies,
hidden among the reeds in the marsh.
22 The lotuses conceal it in their shadow;
the poplars by the stream surround it.
23 A raging river does not alarm it;
it is secure, though the Jordan should surge against its mouth.
24 Can anyone capture it by the eyes,
or trap it and pierce its nose?
--Job 40: 15-24 NIV
