"If one does not look up the true definition and makes up the definition of the word as they like to fit their presupposition that is what it will be to them, but it does not refer to reproductive organ." Well you got me. It probably isn't a reference to the reproductive organs.
"I believe it is a larger animal than that of a hippo or elephant, which I am sure is not what is referred to in the scripture."
Neither what you believe nor what I believe can be taken as verification that Sauropods lived at the same time as man. Objective evidence such as a sauropod fossil found along with human fossils or artifacts would be much better, yet all of the artifacts and human fossils we have found are in stratigraphic layers much younger than every dino fossil ever found.
In any case, how would finding that dinos did not die out as early as thought be evidence for a global flood? Is the existence of modern whales, sharks, crocodiles, coelacanths, etc. evidence for a global flood.
Do not go to Texas where you may see man foot prints and dinosaur prints in the same level of rock.
Do not believe the Roman Coins with dragon depictions on them.
Do not believe the Inca Stones with depictions of dragons on them. Or the fact that the skin pattern depicted was only recently verified.
As to you belief that they went extinct before the flood is unknown. That is assuming you even believe in the Flood of Noah's day.
Before the flood things lived longer and grew larger. After the flood things did not live as long therefore did not grow as large.
It is a scientific fact that reptiles grow until they die. So pre flood larger, post flood smaller.
There are many legends (which is not a scientific fact, same as evolution is not scientific but a hypothesis on unproved ideals) of dinosaurs seem by tribal people in South America and Africa.
