Well, I am an idiot, but here is what I think. There was no 65 million years ago. The earth is only about 6,000 years old. Anymore questions email me at connorpkirkpatrick@gmail.com I have only one source to back up my claim, and my source answers all questions with the same answer without even regarding the questions.
Disregard the previous statement while realizing that the author accepts a claim by a man who derived the age of the Earth by adding up the ages of the people mentioned by The Bible. This is both unscientific and just plain wrong. If we know that books are missing from the Bible, which is a man made work in the first place, then we can't possible assume that everyone that existed is listed in Genesis.
To answer your question, an exact answer can not be known, but scientists deduce that anything over 40 pounds could not have survived the event(s) that destroyed the dinosaurs. They estimate 75% of life was destroyed (17% of all families, 50% of all genera.
WE MUST ACCEPT THAT GOD IS NOT REAL. GOD AND THE BIBLE ARE RELICS FROM A TIME WHEN MANKIND HAD ALMOST NO UNDERSTANDING OF SCIENCE. RELIGION IS AN ATTEMPT TO ANSWER QUESTIONS THAT ARE DIFFICULT TO ANSWER. Religion has hurt mankind beyond anything else. Especially Christianity, the religion that the bloodiest and most ruthless people ever have espoused. History has repeated itself and will continue to do so unless we cast aside the chains of religion. Stop the blind faith. Stop believing because you were born into something. IT DIDN'T HAPPEN PEOPLE, MOVE ON.
