Jurassic Period, second of three periods of the Mesozoic Era. Extending from 201.3 million to 145 million years ago, it immediately followed the Triassic Period (251.9 million to 201.3 million years ago) and was succeeded by the Cretaceous Period (145 million to 66 million years ago).

Which Period of time came after Jurassic?
Cretaceous Period, in geologic time, the last of the three periods of the Mesozoic Era. The Cretaceous began 145.0 million years ago and ended 66 million years ago; it followed the Jurassic Period and was succeeded by the Paleogene Period (the first of the two periods into which the Tertiary Period was divided).
Why did the Jurassic era end?
The cause of this extinction is unknown, but there is some speculation (by sedimentologist Stephen P. Hesselbo et al.) that it was triggered by the release of huge methane deposits from within the Earth (these deposits formed beneath the seabed as surface algae dies and sinks to the sea floor).
What came after the dinosaurs?
About 60 million years ago, after ocean dinosaurs went extinct, the sea was a much safer place. Marine reptiles no longer dominated, so there was lots of food around, and birds like penguins had room to evolve and grow. Eventually, penguins morphed into tall, waddling predators.
What are the 3 eras of dinosaurs?
The 'Age of Dinosaurs' (the Mesozoic Era) included three consecutive geologic time periods (the Triassic, Jurassic, and Cretaceous Periods). Different dinosaur species lived during each of these three periods.
Which is older Silurian or Cambrian?
The major divisions of the Paleozoic Era, from oldest to youngest, are the Cambrian (541 million to 485.4 million years ago), Ordovician (485.4 million to 443.8 million years ago), Silurian (443.8 million to 419.2 million years ago), Devonian (419.2 million to 358.9 million years ago), Carboniferous (358.9 million to ...
What went extinct during the Jurassic period?
At the end of the period there was one of mass extinctions associated with the dinosaurs (Condie, 344). This dinosaur extinction was paralleled by a shift in dominate vegetation from the conifers and cycads of the Jurassic period to shorter, primitive flowering trees (346).
What did the world look like during dinosaurs?
All continents during the Triassic Period were part of a single land mass called Pangaea. This meant that differences between animals or plants found in different areas were minor. The climate was relatively hot and dry, and much of the land was covered with large deserts. Unlike today, there were no polar ice caps.
Can global warming bring Jurassic era?
Answer: yes, it can brings back the jurassic era ,due to high amount of heat ( the reason why the dianosors died ) as human body infact every living organisms cannot survive in high amount of heat , gases etc........
How did life evolve after the dinosaurs?
Plants and animals came back much faster than thought, with plants spurring mammals to diversify, the team reports today in Science. ... Half the plant species died out. With the great dinosaurs gone, mammals expanded, and the new study traces that process in exquisite detail.
Can humans go extinct?
Scientists say there is relatively low risk of near term human extinction due to natural causes. The likelihood of human extinction through our own activities, however, is a current area of research and debate.
Can dinosaurs come back?
The answer is YES. In fact they will return to the face of the earth in 2050. We found a pregnant T. rex fossil and had DNA in it this is rare and this helps scientists take a step closer of animal cloning a Tyrannosaurus rex and other dinosaurs.
Did T Rex live in Jurassic period?
tyrannosaur, any of a group of predatory dinosaurs that lived from the late Jurassic Period (about 150 million years ago) to the latest Cretaceous Period (about 65 million years ago), at which time they reached their greatest dominance. ... The best-known and largest member of the group is Tyrannosaurus rex, or T. rex.
What dinosaurs had 500 teeth?
This bizarre, long-necked dinosaur is characterized by its unusually broad, straight-edged muzzle tipped with more than 500 replaceable teeth. The original fossil skull of Nigersaurus is one of the first dinosaur skulls to be digitally reconstructed from CT scans.
How long after dinosaurs did humans appear?
After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.
