none dinosaurs are extinct
California was under a shallow sea during the time that dinosaurs lived. Dinosaurs lived on land, so none lived in California.
Plesiosaurs were not dinosaurs. They were a clade of marine reptiles that lived at the same time as the dinosaurs.
No! Although this is a common mistake, all dinosaurs were land animals. All animals that lived in the sea at the same time as the dinosaurs weren't actually classed as dinosaurs even though they have similarities :)
No way! There were thousands of species of reptiles that lived both during, before, and after the dinosaurs lived on earth. There were the synapsid reptiles, as well as the anapsid reptiles, which were mostly gone when the dinosaurs arrived. There were also many diapsid reptiles that lived during the time the dinosaurs did. Such species include deinosuchus, dimetrodon, gorgonops, Quetzalcoatlus, and rutiodon. Dinosaurs were not reptiles themelves. They evolved from reptiles, many had warm blood even feathers,

Dinosaurs lived from the Triassic to the Jurassic to the Cretaceous, which means that they lived in an entire era called the Mesozoic. Dinosaurs lived 230-65 million years ago. In the Mesozoic era.
the dinosaurs lived from 250 million years ago to 65 million years ago.

The Dinosaurs lived in 3 Geologic time periods-The Triassic, Jurassic, and Cretaceous. These 3 time periods where the three periods of the Mesozoic Era, which is also known as the Age of Reptiles.
There were many species of flying reptiles that lived during the Mesozoic Era. Some examples of them are Pteranodon, Pterodactyl, and Quetzalcoatlus.
There were many animals that coexisted with dinosaurs. There were mutlituberculate and marsupial mammals, such as Ptiloduc, Didelphodon, and Alphadon. There were pterosaurs in the air and relatives of modern crocodiles in freshwater habitats. Some crocodile like animals lived strictly on land at that time. Lizards, frogs, and salamanders lived alongside dinosaurs. And most invertebrate groups that exist today had representatives alive at the time of the dinosaurs.
