The Jurassic period lasted from 199 million years ago until 145 million years ago. The average temperature was 3 degrees Celsius (5.4 degrees Fahrenheit) warmer than today's average.
Back then, the New World and the Old World were just beginning to split, beginning the formation of the Atlantic Ocean. Europe was a cluster of islands, very close to North America. South America was connected to Africa, but both South America and Africa together were separate from the other continents. Australia and Antarctica were merged together, and barely separated from Africa and South America.
North America and Africa both had savanna climates.
At this time, the dominant plants were conifer trees, and other common plants included cycads, cycadeoids, ferns, and ginkgoes. There were no flowering plants at this time.
The dominant land animals were the dinosaurs. During the Jurassic, they greatly diversified, evolving into sauropods (long necked, herbivorous dinosaurs) such as Brachiosaurus, Diplodocus, Apatosaurus, and Camerasaurus, carnivores such as Allosaurus, and the famous Stegosaurus, as well as the ancestors of the Iguanodontids and hadrosaurs. In the ocean, the dominant animals were plesiosaurs, some with long necks, and others with short necks that looked a lot like giant crocodiles. In the air, there were pterasaurs (flying reptiles). Other animals included smaller reptiles, small mammals, frogs, salamanders, and even the primitive ancestors of birds.
1. Most dinosaurs were actually vegetarians!
2. The T-Rex wasn't even alive during this time!

yes there were plants during this time period. there were trees
I believe that dont know
Triassic
Dinosaurs first appeared in the middle of the Triassic period. The extinction during the Triassic-Jurassic periods allowed dinosaurs to grow to mammoth proportions.
jurassic The Triassic was the earliest period of the Mesozoic, followed by the Jurassic then the Cretaceous. The Cretaceous was of the greatest duration.
Thrinaxodon lived during the Triassic Period. They died out about 245 million years ago, at the end of the Olenekian portion of the Triassic period.
Triassic Period! :)
yes there were plants during this time period. there were trees
No. Fruit trees first appeared during the Cretaceous, two periods after the Triassic. The only trees in the Triassic were conifers.
1) Pangea begun to break apart during this period. 2) Dinosaurs began to evolve during the Triassic Period. 3) The joining and separating of the continents affected which kinds of dinosaurs lived where.

No. the first Dinosaurs were in the Triassic period, which came later
The period after the Triassic is the Jurassic.

After the Triassic period, the Jurassic period began, followed by the Cretaceous.
