How did dinosaurs fit on Noah's Ark?
Most dinosaurs were reasonably small - the size of a sheep or pony, on average. Even large sauropods, as young adults, were not overly large. So Noah's Ark had plenty of room for all the land animal kinds, including every dinosaur "kind".
Is there any other evidence of "dinosaurs" living after the flood?
Dragons may have been dinosaurs. Dragon legends exist all over the world, depicting creatures that lived with humans. The country of Wales has a dragon on its flag as its national emblem. Many of the dragon descriptions, carvings, and paintings fit with our understanding on dinosaurs.
What happened to the dinosaurs?
They died out, probably in very recent times. Like many other animals since the Flood, climate changes, diseases, humans and other factors probably caused the extinction of dinosaurs.
Are human bones found with dinosaur fossils?
None have been discovered yet. However, if human bones aren't found with dinosaur bones, it simply means they weren't buried together. Humans have come in contact with lots of animals, like crocodiles and coelacanths, but they aren't buried with humans.
These guys should write comic books.
