If the Hebrew expression translated “great sea monsters” [Hebrew, tan·ni·nim′] includes dinosaurs, which often inhabited swampy, watery areas, this would mean that dinosaurs were created on the fifth “day.” (Gen. 1:21) We do not know whether they continued to exist until man was created (toward the close of the sixth “day”). At the very latest it seems likely that they must have disappeared off the earth at the time of the flood of Noah’s day. Dinosaurs were reptiles, and some kinds of dinosaurs bear strong resemblance structurally and otherwise to lizards (sauros is, in fact, the Greek word for “lizard”; saura in Leviticus 11:29, LXX). Not all types of dinosaurs were of such gigantic size. Hence, even if they had survived till the Flood, this would not have required taking pairs of the mammoth varieties into the ark. Other smaller members of the particular family or “kind” to which these belonged would have sufficed to fulfill the divine command.
