T. Rex Toddler Answers Noah's Ark Questions

In 2006, the fossil of a juvenile Tyrannosaurus-like dinosaur named Tarbosaurus was collected from the Gobi Desert. Investigators examined the fossil in detail this year and estimated that the creature died at two to three years of age. This young specimen not only offers insights into the growth and development of these dinosaurs, it also sheds light on certain misconceptions connected to the biblical account of Noah's Ark.

Paleontologists examined tell-tale growth markers found inside the Tarbosaurus fossil leg bones to establish its approximate age. In a study published in the Journal of Vertebrate Paleontology, they estimated that the girth of its tibia bone grew at just over a centimeter per year on average.1 At two or three years of age, the youngster was nine feet long from nose to tail, but weighed only about 70 pounds.2

This fossil's description inadvertently refutes two common but uninformed objections to the historicity of the Bible's account of Noah's Ark. First, critics often claim that large creatures such as tyrannosaurs could not possibly have fit on such a relatively small vessel. Similarly, there is supposed to be no way that all the species of animals could have been transported in Noah's famed wooden barge.

The first objection assumes that Noah and his family had to have taken full-grown dinosaurs on board the Ark, which is typically presumed to have been smaller than its actual biblical dimensions. The Ark was at least 45 feet high, minus the required dimensions for hull structure.3 If the three decks that the Lord specified for its construction were evenly spaced from bottom to top, they would have offered about 15 feet of clearance. Tyrannosaurs could reach 40 feet in length, and the adults would therefore not have fit well on such a deck.

But why would Noah have taken older dinosaurs on board, when younger ones would have fit just fine? The juvenile Tarbosaurus under investigation would have stood waist-high next to most men, and therefore it would have been easily accommodated on the Ark.

Regarding the question of how all the different species could have fit on the Ark, Asia's Tarbosaurus looks so much like North America's Tyrannosaurus that some evolutionary paleontologists suggest that they should be considered the same species. The study authors found a list of clear similarities between their Tarbosaurus specimen and tyrannosaurs, including the "D-shaped" cross-section of the teeth and the distinctive two-fingered tiny forearms.

It is therefore very probable that both these creatures, though granted separate "species" names by virtue of having been found on separate continents, nevertheless were part of the same tyrannosaurids that were one of the "[beasts] of the earth" created to reproduce "after [their] kind."4 Noah was not required to board every species, but only two of every kind—a much broader category than species.5

Researcher John Woodmorappe generously equated "kinds" with the modern, broader classification "genus," noting that many animals grouped in the still-broader designation of "family" can interbreed. Adding all the kinds of nostril-breathing, land-living creatures—both extinct and extant—Woodmorappe estimated that 16,000 animals went aboard the Ark, requiring a maximum of only two of its three decks.6

It has also been suggested that the dinosaur genus Nanotyrannus was just a juvenile Tyrannosaurus.7 Thus, three different species, and probably more, could have been represented by only two youthful tyrannosaurids on the Ark. The Tarbosaurus toddler illustrates two reasons why Noah's Ark was a feasible project. Not only did Noah only need to take juvenile members of very large creature groups, but he only had to take two of every kind—not two of every "species." And the Ark was more than capable of handling that.
