What year did the plesosaur exist?
Plesiosaurs existed during the Mesozoic Era, particularly during the Jurassic and Cretaceous periods, which ranged from about 201 to 66 million years ago.
Which species evolved during the Cretaceous period?
Willow tree, a type of angiosperm
Fossil of dinosaurs are found in Cretaceous rock but not in tertiary rock?
This statement is not accurate. Fossils of dinosaurs have been found in both Cretaceous and Tertiary rock layers. The Cretaceous period ended around 66 million years ago, and the Tertiary period followed, lasting until about 2.6 million years ago. Dinosaurs lived during the Mesozoic Era, which includes the Triassic, Jurassic, and Cretaceous periods.
When did dinosaurs exist?
Non-avian dinosaurs existed from around 230 million years ago in the Triassic period until the end of the Cretaceous period, 65 million years ago. The cause of their extinction is most likely an asteroid impact coupled with environmental change.
Dinosaurs and angiosperms were the most visibly dominant lineages during which geologic era?
I know that the angiosperms were most dominant during the cretaceous period but im not too sure about the dinosaurs dominant era. I would assume they were both dominant in the same era but I am not 100% sure.Read more: http://wiki.answers.com/Dinosaurs_and_angiosperms_were_dominant_lineages_during_with_geologic_era#ixzz1G5bqBpQR
What was the dominant land animal during the Jurassic and cretaceous period?
The dinosaurs were the dominant land animals during the Jurassic and Cretaceous periods, rising to dominance during the late Triassic.
How many pirod was there during the dinosaur time?
There were three periods during the mesozoic era; the Triassic, Jurassic and Cretaceous.
What Era did dinosaurs live in?
The dinosaurs lived in the Mesozoic Era, which includes the Triassic, Jurassic, and Cretaceous periods. The first dinosaurs appeared in the late Triassic and went extinct at the end of the Cretaceous.
What are the three time periods the dinosaurs live in?
Dinosaurs lived from the Triassic to the Jurassic to the Cretaceous Or Dinosaurs lived 150 - 65 million years ago, that was during the Triassic, Juassic and the Cretaceous periods.
What period were dinosaurs from?
None-avian dinosaurs first appeared in the Triassic period and were the dominant land vertebrates through the Jurassic and Cretaceous periods. At the end of the Cretaceous period, 65.5 million years ago, all non-avian dinosaurs went extinct. Birds, which are now classified as dinosaurs, continue to live to his day.
What era did dinosaurs dominated earth?
Dinosaurs dominated the Earth during the Mesozoic Era, which lasted from approximately 252 to 66 million years ago. This era is divided into three periods: the Triassic, Jurassic, and Cretaceous. Dinosaurs thrived during these periods, particularly in the Jurassic and Cretaceous, until their extinction at the end of the Cretaceous period, likely due to a combination of volcanic activity and an asteroid impact.
What is a sitta osaurus?
There is no animal called the sitta osaurus. There is however, a stegosaurus. A stegosaurus was a herbivore that lived during the Jurassic and Cretaceous periods.
What were the three main time preiods of the dinosaur?

When did Dakosaurus exist?
During the Late Jurassic and Early Cretaceous.
The breakup of Pangaea occurred during the .?
The breakup of Pangaea occurred during the Mesozoic Era, specifically during the Jurassic and Cretaceous periods. This process led to the formation of the modern continents we know today.
What is the dominant vertebrates throughout the Cretaceous period?
The common consensus is that dinosaurs dominated the land, being the most diverse large animals, and reaching huge sizes. In the oceans, large marine creatures included plesiosaurs, pliosaurs, ichthyosaurs (during the Jurassic and early Cretaceous), and mosasaurs (during the Cretaceous). The skies were ruled by pterosaurs. Coniferous trees were the primary large plants.
