Since dinosaur fossils are usually found embedded in rock, paleontologists associate dinosaurs with the geologic period in which they lived—for example, "the sauropods of the late Jurassic."]]> 2020-04-27 18:53:00 UTC https://padlet.com/kalebhuang1/zbab46f0fdblmt4g/wish/534453573 kalebhuang1 https://padlet.com/kalebhuang1/zbab46f0fdblmt4g/wish/534453574 237–201 million years ago

At the start of the Triassic period, 250 million years ago, the Earth was just recovering from the Permian/Triassic Extinction, which witnessed the demise of over two-thirds of all land-dwelling species and a whopping 95 percent of ocean-dwelling species.]]> 2020-04-27 18:53:00 UTC https://padlet.com/kalebhuang1/zbab46f0fdblmt4g/wish/534453574 kalebhuang1 https://padlet.com/kalebhuang1/zbab46f0fdblmt4g/wish/534453575 Sometimes called “ruling reptiles,” this group of ancient animals included dinosaurs and pterosaurs (flying reptiles)]]> 2020-04-27 18:53:00 UTC https://padlet.com/kalebhuang1/zbab46f0fdblmt4g/wish/534453575 kalebhuang1 https://padlet.com/kalebhuang1/zbab46f0fdblmt4g/wish/534453577 A group of ancient reptiles that later evolved to become mammals]]> 2020-04-27 18:53:00 UTC https://padlet.com/kalebhuang1/zbab46f0fdblmt4g/wish/534453577 kalebhuang1 https://padlet.com/kalebhuang1/zbab46f0fdblmt4g/wish/534453578 Long-necked marine animals (often described as similar to the Loch Ness monster)]]> 2020-04-27 18:53:00 UTC https://padlet.com/kalebhuang1/zbab46f0fdblmt4g/wish/534453578 kalebhuang1 https://padlet.com/kalebhuang1/zbab46f0fdblmt4g/wish/534453579 Ichthyosaurs are large extinct marine reptiles.

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 Earth, a far cry from their slender, man-sized ancestors of the preceding Triassic period. But the fact is that dinosaur diversity reached its peak in the ensuing Cretaceous period.]]> 2020-04-27 18:53:00 UTC https://padlet.com/kalebhuang1/zbab46f0fdblmt4g/wish/534453581 kalebhuang1 https://padlet.com/kalebhuang1/zbab46f0fdblmt4g/wish/534453582 Huge long-necked, long-tailed vegetarian dinosaurs (such as the Apatosaur)
