Well,” Ellie said. “We know animals have survived. Crocodiles are basically Triassic animals living in the present. Sharks are Triassic. So we know it has happened before.”.
A geologic period within the Mesozoic era; comprises lower, middle and upper epochs from about 250 to 200 million years ago
The first period of the Mesozoic era (after the Permian of the Paleozoic era, and before the Jurassic) thought to have covered the span of time between 225 and 190 Ma; also, the corresponding system of rocks
A period in the geologic time scale that spans from 245 to 208 million years ago
Geologic period that occurred roughly 208 to 245 million years ago During this period, the first dinosaurs appeared
from 230 million to 190 million years ago; dinosaurs, marine reptiles; volcanic activity
The first geological period of the Mesozoic It lasted from 225 Ma until 190 Ma This period saw many land animal groups come and go, ending with the archosaurs diversifying into many of the niches available
(tri-asik)adj Of, belonging to, or being the geologic time, system of rocks, and sedimentary deposits of the first period of the Mesozoic Era, after the Permian Period of the Paleozoic Era and before the Jurassic Period of the Mesozoic Era n The Triassic Period or its system of deposits [Late Latin trias, triad (from the subdivision of this period into three parts) See TRIAD + -IC ] [Back To Top]
The earliest period of the Mesozoic era, spanning the time between 248 and 213 million years ago The name Triassic refers to the threefold division of rocks of this age in Germany
Interval of geologic time, 248-206 million years ago, that marks the beginning of the Mesozoic Era. Many new vertebrates emerged during the Triassic, heralding the major changes that were to occur in both terrestrial and marine life forms during the Mesozoic Era. The seas became inhabited by large marine reptiles. On land, ancestral forms of various modern amphibians arose, as did reptiles such as turtles and crocodilians. By the Late Triassic, archosaurs were becoming more and more dominant, and the first true mammals, small shrewlike omnivores, evolved. Seed ferns dominated the flora of southern Gondwana, and gymnosperms, including conifers, cycads, and ginkgos, were common throughout much of Pangea
