How Did Those Huge Dinosaurs Fit on the Ark?
Although there are about 668 names of dinosaurs, there are perhaps only 55 different “kinds” of dinosaurs. Furthermore, not all dinosaurs were huge like the brachiosaurus, and even those dinosaurs on the Ark were probably “teenagers” or young adults.
Creationist researcher John Woodmorappe has calculated that Noah had on board with him representatives from about 8,000 animal genera (including some now-extinct animals), or around 16,000 individual animals. When you realize that horses, zebras, and donkeys are probably descended from the horse-like “kind,” Noah did not have to carry two sets of each such animal. Also, dogs, wolves, and coyotes are probably from a single canine “kind,” so hundreds of different dogs were not needed.
According to Genesis 6:15, the Ark measured 300 x 50 x 30 cubits, which is about 460 x 75 x 44 feet, with a volume of about 1.52 million cubic feet. Researchers have shown that this is the equivalent volume of 522 standard railroad stock cars (US), each of which can hold 240 sheep. By the way, only 11% of all land animals are larger than a sheep.
Without getting into all the math, the 16,000-plus animals would have occupied much less than half the space in the Ark (even allowing them some moving-around space).
Conclusion
The Bible is reliable in all areas, including its account of the Ark (and the worldwide catastrophic Flood). A Christian doesn’t have to have a blind faith to believe that there really was an Ark. What the Bible says about the Ark can even be measured and tested today.
