NOTE:

The dinosaurs on Noah’s ark were probably juveniles. We can speculate this for two reasons; first, since dinosaurs were reptiles, they probably continued to grow throughout their lives. In their adult stage, the dinosaurs would have been quite large (e.g. the Sauropod could grow to 40 feet (12 meters) in length, 60 feet (18 meters) in height, and weigh 70 to 80 tons.).

It would be much easier to house young dinosaurs on the ark. Secondly, God put the animals on the ark specifically to repopulate the world after the flood. Since the animals had to be able to reproduce after the flood year, God would have saved younger animals to secure their reproductive viability.
