PLESIOSAUR / PLIOSAUR EARLY JURASSIC TO CRETACEOUS PERIOD: 220 million - 65 million years ago. Plesiosaurs were magnificent ocean-dwelling reptiles that flew gracefully through the water with massive paddles. They are often mistakenly called 'dinosaurs' but they not dinosaurs and are correctly classified as marine reptiles. They were around almost as long as the dinosaurs from the Triassic period 220 million years ago until the end of the Cretaceous 65 million years ago. Their remains have been found on every continent.

- Dinosaurs died at the very end of the Cretaceous period, which was from about 65 to 145 million years ago.     The Jurassic period was before the Cretaceous period and … was the period between 145 to 200 million years ago.The Triassic period was before the Jurassic period, and was the period between 200 million to 251 million years ago.nswered by The Community. Making the world better, one answer at a time. No, dinosaus became extinct at the end of the Cretaceous Period. They ended up dying because the dust was so bad that it changed the weather, which changed the temperature and the way plants grow, which eventually killed off the dinosaurs.

Learn About the Different Dinosaur Periods Thanks to the movie Jurassic Park, people identify the Jurassic period, more than any other geological time span, with the age of dinosaurs. The Jurassic is when the first gigantic sauropod and theropod dinosaurs appeared on the earth, a far cry from their slender, man-sized ancestors of the preceding Triassic period.

- The Carboniferous period (360-300 million years ago) is famous for its dense coal swamps that eventually turned into modern coal deposits. It was during the Carboniferous that the first true amphibians appeared, evolving by the start of the ensuing Permian period into the first reptiles and lizards.

Triassic Period and Dinosaurs That Lived In The Scientists believe that Triassic period ended by a huge volcanic eruptions about 207-212 million years ago. The Pangaean continent breaks into many parts. About 35% animal die and extinct. Primitive dinosaurs were extinct too, but remaining dinosaurs evolved to be more adaptive in the next era, the Jurassic Era. This extinction made dinosaurs as the dominant , abundant and diverse creatures to “rule” the Earth for the next 150 million years. Here are the complete list of Dinosaurs that lived in Triassic Period. ( Source: Wikipedia) A

- Dinosaurs are a diverse group of reptiles of the clade Dinosauria that first appeared during the Triassic period. Although the exact origin and timing of the evolution of dinosaurs is the subject of active research, the current scientific consensus places their origin between 231 and 243 million years ago. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201 million years ago.

Cretaceous Plants Some plants from the Jurassic period were still around, such as mosses, ferns, horsetails, cycads and conifers. More and more flowering plants (angiosperms) now began to appear. They quickly spread and became the main ground covering. This evolution was helped by the new appearance of bees to pollinate the plants.

Cretaceous Period The name is now applied to all materials deposited above Jurassic Period rocks but below Tertiary Period rocks. During the Cretaceous more land was submerged than at any time since the Ordovician Period. Tectonic plates moved apart, causing major mountain building, and continents began to resemble those existing today.

Geologic Time Scale The hey day of the dinosaurs occurs. Appearance of the famous T-Rex.This period had high tectonic and volcanic activity. Primitive marsupials developed. It was the first appearance of flowering plants. It ended with the K-T extinction of dinosaurs, pterosaurus, ammonites, and 50% of marine invertebrates that was probably caused by an asteroid impact. It was the heyday of dinosaurs.

- Jurassic Period: Life. Today, the name Jurassic conjures up images of the phenomenally successful book and movie, Jurassic Park. It is quite true that the dinosaurs dominated the land fauna -- although many of the dinosaurs featured in Jurassic Park, such as Triceratops and Tyrannosaurus rex, did not evolve until after the Jurassic was over.
