The scriptures indicate that all flesh will be resurrected and that God will reverse the curse of sin which is death. Will dinosaurs be resurrected and will they be present on the New Earth along with resurrected mankind?
Luke 3:6 does in fact say:
“And all flesh shall see the salvation of God” (KJV). (και οψεται πασα σαρξ το σωτηριον του θεου).
And then 1 Cor. 15:39 says:
“All flesh is not the same flesh: but there is one kind of flesh of men, another flesh of beasts, another of fishes, and another of birds”. (ου πασα σαρξ η αυτη σαρξ αλλα αλλη μεν ανθρωπων αλλη δε σαρξ κτηνων αλλη δε σαρξ πτηνων αλλη δε ιχθυων).
So it is probably a legitimate exegetical position to say that “all flesh” (men, beasts, fishes, birds…and why not dinosaurs?) “shall see the salvation of God”.
