When did the Dinosaurs go extinct according to christians?

About 65 million years ago according to science, and therefore according to a majority of Christians.

When did God create dinosaurs, and when did they become extinct?

The Bible does not provide specific answers to this question.

If the Hebrew expression translated great sea monsters includes dinosaurs, which often inhabited swampy, watery areas, this would mean that dinosaurs were created on the fifth day.

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.

According to historical records, it appears somewhere around the 1500s.

However, there are natives deep in the Congo who when shown pictures of different animals, won't recognize a bear or a humming bird, but will recognize a sauropod, whom they call "Mokele-Mbembe", so it's possible that they are not entirely extinct.

Christians hedge the answer.  Instead, they insist that "missing links" don't exist, and assert that God instantaneously created creatures, thus dinosaur fossils strengthen their beliefs.  In the second link, Christians point out that dinosaur fossils contain blood cells and collagen that would have rotted away in 65 million years, but must indicate, instead, that the fossil is merely 6,000 years old, and myths of dragons are merely encounters of modern men and dinosaurs.  Could it be that dragon myths were created by finding dinosaur bones?  Some Christians assert that the dragons mentioned in the bible are really dinosaurs.

Oh, the whale is still in the ocean so I bet the walking dino is on this earth hidden some where.

Christians believe that dinosaurs disappeared around 1863. This coincides with the completion of the transcontinental railroad. The dinosaurs died along with the buffalo.

Most Christians around the world agree with the accepted evidence-supported view of when the dinosaurs lived and died, between 230 and 65 million years ago.

You are likely wondering what young-earth creationists think about the subject.  You can find that here:

Warning: it is *profoundly* stupid.  I personally find it too dumb to be funny, but your mileage may vary.

A person can know numerous truths by reciting the rosary every day with care and sincerity.

Do you any proof they were ever alive....I mean we have rocks in the shape of bones, aka Fossils.   Put all that proves is that fossils exist

Probably part of the history God gave a 4 billion year old earth when he created it 6000 years ago

WE HAVE no way of knowing and it has nothing to do with religion.
