Here are some animals groups that live during the Mesozoic: Mammals which apeared about 200mya. Dinosaurs. By the cretaceous Birds had evolved from theropod dinosaurs. Pterosaurs Pleisosaurs and Pliosaurs Lizards. Snakes which first apeared during the Mesozoic. Mosasaurs. Sharks and Fish Insects.
yes the only time during the mesozoic in which they didn't exist was the earliest triassic, when they had not yet evolved. some people think that birds are dinosaurs, in which case dinosaurs would also be in the Cenozoic (the period immediately after the mesozoic, which is the one that occurs today).
It is hard to say what animal group was the most successful during the Mesozoic. However, reptiles were the so called "dominant" animals. Dinosaurs lived on land, pterosaurs flew through the air, and plesiosaurs, icthyosaurs, and mosasaurs were some of the largest creatures in the oceans.

The first dinosaurs evolved in the Mesozoic. At the end of the Mesozoic, all non avian dinosaurs became extinct. Therefor, all non avian dinosaurs, and some avian dinosaurs (birds), lived in the Mesozoic.

Toothed birds lived in the Mesozoic Era during the Cretaceous Period, specifically in the Late Cretaceous. They were among some of the earliest birds that evolved before losing their teeth as part of their adaptation for flight.
No, the sunrise itself does not make any noise. However, some atmospheric conditions during sunrise, such as birds chirping or wind rustling through trees, may create sounds associated with the sunrise experience.

No. The 1st vertebrates appeared in the fossil record about 525 million years ago during the Cambrian Period. This was in the Paleozoic Era.
There were many species of flying reptiles that lived during the Mesozoic Era. Some examples of them are Pteranodon, Pterodactyl, and Quetzalcoatlus.
