No, dinosaurs were not alive during the Ice Age. Dinosaurs roamed the Earth during the Mesozoic Era, which spanned from about 252 to 66 million years ago. They became extinct long before the Ice Age, which began approximately 2.4 million years ago and lasted until about 11,700 years ago.
The extinction event that wiped out the dinosaurs occurred around 66 million years ago, likely due to a combination of volcanic activity and a massive asteroid impact. This event marked the end of the Cretaceous period, the last period of the dinosaur age.
During the Ice Age, the dominant terrestrial animals were mammals, such as mammoths and saber-toothed cats, which adapted to the colder climates. Thus, while dinosaurs are fascinating creatures that once ruled the Earth, their era had long passed before the Ice Age began.
