Genesis 1:21

"God created the great creatures of the sea and every living thing with which the water teems and that moves about in it, according to their kinds, and every winged bird according to its kind. And God saw that it was good."  Genesis 1:21

So again God has created exactly what he said he was going to create.  Now all the waters and skies are filled with the creatures that swim and fly, and God sees that it is good.  There's no way of knowing how many of each kind God created, but it was enough that they could multiply and thrive.  I don't know if any of these are dinosaurs, but I tend to believe there were.  Like the great creatures of the sea, I think included not just whales, but dinosaurs also.  But no where does it ever give an exhaustive list of the animals God created in the Bible.
