There is no evidence to support such a claim. Fantastic creatures appear in folklore from all times and places. There is no reason to believe that the ancient Hebrews would be different.
The "tail like a cedar," which creationists think indicates a large dinosaur, is not even a real tail. "Tail" was used as a euphemism in the King James version. A more likely translation for the phrase is, "His penis stiffens like a cedar" (Mitchell 1987). The behemoth was probably a bull, and the cedar comparison referred to its virility.
