Bit of a stretch to say the dinosaurs were around in Jesus day...
But see Job 40 beginning in v 15.
“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; the sinews of his thighs are close-knit. 18 His bones are tubes of bronze, his limbs like rods of iron.
