Job is believed to have been a contemporary of Abraham. The Biblical descriptions of Leviathan and Behemoth would qualify them as dinos. Job was antediluvian. Dinos were antediluvian.
Job 40:15-19
15 Behold now behemoth, which I made with thee; he eateth grass as an ox.
16 Lo now, his strength [is] in his loins, and his force [is] in the navel of his belly.
17 He moveth his tail like a cedar: the sinews of his stones are wrapped together.
18 His bones [are as] strong pieces of brass; his bones [are] like bars of iron.
19 He [is] the chief of the ways of God: he that made him can make his sword to approach [unto him].
Job 41:1-10
1 Canst thou draw out leviathan with an hook? or his tongue with a cord [which] thou lettest down? 2 Canst thou put an hook into his nose? or bore his jaw through with a thorn?
3 Will he make many supplications unto thee? will he speak soft [words] unto thee?
4 Will he make a covenant with thee? wilt thou take him for a servant for ever?
5 Wilt thou play with him as [with] a bird? or wilt thou bind him for thy maidens?
6 Shall the companions make a banquet of him? shall they part him among the merchants? 7 Canst thou fill his skin with barbed irons? or his head with fish spears?
8 Lay thine hand upon him, remember the battle, do no more.
9 Behold, the hope of him is in vain: shall not [one] be cast down even at the sight of him?
10 None [is so] fierce that dare stir him up: who then is able to stand before me?
"Leviathan" and "Behemoth" were dinosaurs? What criteria do you use to define a dinosaur?
Job 40:15-19 15 Behold now behemoth, which I made with thee; he eateth grass as an ox.
Dum Dum's interpret this to mean he had a tail like a cedar. But then Dum Dum's never made it past the fourth grade.
