This is a laughable suggestion to those who do not believe in creation or the worldwide flood in Noah’s day. But the dinosaurs could easily have been accommodated on board the Ark. The Ark that God gave Noah the instructions to build was a huge enclosed barge-like vessel with three decks inside, a small window, and a large door in its side. The dimensions for the vessel was 300 cubits (450 feet) long, 50 cubits (75 feet) wide, and 30 cubits (45 feet) high. Noah’s Ark was built to float. It did not have rudders or sails on it. God directed it were He wanted it to go. The Ark had the capacity at these dimensions to easily accommodate approximately 16,000 animals. Put into perspective the equivalent volume of the Ark was equal to 522 railroad livestock cars each of which can hold 240 sheep. God brought to Noah pairs of each kind (or basic type) of land-dwelling air breathing animals for him to put on the Ark (Genesis 7:2,3,8,22). This requirement would have included the dinosaurs, after all God created them, along with man, on day six (Genesis 1:24-27).
Here is some “dinosaurs on the Ark” questions that can be answered. How did Noah squeeze hundreds of different dinosaur species into the Ark along with the other animals? Noah did not put each species, but two of each “kind” on the Ark. Paleontologists make careers out of inventing new species names, but there were really only about 60 different basic dinosaur kinds. That would be about 120 dinosaurs (male and female) that were put on the Ark. Just look at all the species (breeds) of dogs we have now. Not all these dogs were on the Ark. Actually only one “kind” was on the Ark. The dogs we have now are a variation of the “kind” that was on the Ark.
How could Noah have fit enough food aboard to feed all these hunger dinosaurs and other animals for a whole year? Maybe Noah feed them the plants they ate in Genesis chapter one. Or maybe they were able to fast like reptiles and mammals are known to do. Dinosaurs probably ate less than the birds and the mammals that were on the Ark. God might of put them all into a state of hibernation and they stayed that way for a period of time during the Flood. Many animals still hibernate when the winter months set in in places today, especially reptiles.
How did Noah handle the Tyrannosaurus and other carnivores on the Ark? God made a provision for T. rex and other carnivores to keep their mouths shut when Noah and his family were around them. Just like God shut the mouths of the lions when Daniel was thrown into the lion’s den (Daniel 6:22). With God nothing is impossible.
How did the large dinosaurs such as Diplodocus be able to fit on the Ark? God most likely put juvenile dinosaurs on the Ark. Dinosaur eggs such as a sauropod dinosaur were about the size of a football. So even the big-bodied behemoth began small.
The dinosaurs on the Ark survived the Flood (Genesis 6-8), but the ones that were drowned in the Flood or were suffocated by mud, along with the other land-dwelling air breathing creatures are found in the fossil record. During that year successive super-tsunamis sent sandy slurries sliding across land surfaces, swallowing everything in their paths. This not impacts from outer space, is the origin of the vast majority of dinosaur extinction recorded in the fossil record. The dinosaurs that came off Noah’s Ark were introduced to a harsher environment but some survived traveling to more agreeable habitats in tropical regions. Others died out and became the dragon legends we hear today. Yes, dinosaurs were on the Ark.
