The post-flood effects on all the animals were tremendous: the climate, habitat and continental form were all impacted greatly, making it difficult for animals to survive with the same ease as they did before the flood. Moreover, within 110 years after the flood, the human population began to disperse around the world. Most scientists today believe that human pressure was the most significant factor in animal extinction, including dinosaurs (Science, June 8, 2001, p n1819, 1888-1896).

In spite of the harsh conditions they faced, there is evidence that some dinosaurs did live after the flood.

There are some indications that dinosaurs lived after the flood. For example, in the Book of Job, the author discusses the behemoth in chapter 40. The animal described clearly matches the description of a Sauropod (commonly known as a Brontosaurus). However, the Book of Job was written about 300 years after the flood; the present-tense description of the beast indicates that the animal alive at the time had to have descended from the survivors on Noah’s ark.
