Soft tissue, cells, blood in dinosaur remains

What Does Soft Tissue in Dinosaur Bones Mean for Evolution? - Dr. Kevin Anderson - YouTube

The reality is the dinosaurs are not 65 millions yrs old, only a few thousand years and killed by the flood.

 

I think they did. Scripture talks about kinds, not species.
Many varieties of tyrannosaurs existed, so just a pair could represent all tyrannosaurs.
Another of their videos says a kind is not a species, it is a supergroup and within the representative kind of the animal exists all the variations of species.
So for example, they mention 'felids' as a kind under which exist many kinds of cats. So the felid that got on the ark, with the genetics of those 2 individuals existed all the various cat varieties, lions, tigers, domestic cats etc... Dog kind same way.
So no lions and tigers on the ark, just some kind of cat perhaps.

There were many different elephant like creatures in fossils too, but a 'elephant kind could have produced all the varieties of elephants.

The other thing, God draws the animals he wants on the ark, bringing them to Noah , maybe he just did not want some of them.
speculation since we did not see it.

20 Two of every kind of bird, of every kind of animal and of every kind of creature that moves along the ground will come to you to be kept alive.

5 And Noah did all that the Lord commanded him.

6 Noah was six hundred years old when the floodwaters came on the earth. 7 And Noah and his sons and his wife and his sons’ wives entered the ark to escape the waters of the flood. 8 Pairs of clean and unclean animals, of birds and of all creatures that move along the ground, 9 male and female, came to Noah and entered the ark, as God had commanded Noah. 10 And after the seven days the floodwaters came on the earth.

 

God brought the animals to the ark, Noah did not need to go and catch them.
God would have tamed them too. Only after the flood did God put fear and dread of man into the animals. So perhaps the violence before the flood was man against man, not beast against man. but after the flood, animals will be held accountable for killing man.

After the flood, God tells man he can eat animals, before that God had only given plants as food for man.
Genesis 9
So God blessed Noah and his sons, and said to them: “Be fruitful and multiply, and fill the earth. 2 And the fear of you and the dread of you shall be on every beast of the earth, on every bird of the air, on all that move on the earth, and on all the fish of the sea. They are given into your hand. 3 Every moving thing that lives shall be food for you. I have given you all things, even as the green herbs. 4 But you shall not eat flesh with its life, that is, its blood.

5 Surely for your lifeblood I will demand a reckoning; from the hand of every beast I will require it, and from the hand of man. From the hand of every man’s brother I will require the life of man.

verse 5, a life for a life God required for the life blood of a man. Before the flood the earth was full of violence, must have been much killing, so here God reminds man he still cant get away with murder and violence, there will still be a reckoning, even though this is a new start for people.

 

Another thing, God may have after the flood recreated anew any creatures he did not have Noah explicitly bring into the ark, such as fungi, bacteria, protists, maybe insects. Did Noah really want to bring mosquitos, horse flies, gnats, etc... on the ark with him. And I dont expect God would do that to Noah and the animals.
