According to Science Views, no one knows for sure what caused the end of the Jurassic period, but they do know that several species started to die out, which gave rise to the Cretaceous period. Scientists do not believe that the transition from the Jurassic period to the Cretaceous period was as violent as the transition that took place at the start of the Jurassic period.Continue Reading
Science Views says that the Jurassic period started after a large extinction at the end of the Triassic period. Scientists believe that the start of the Jurassic period was caused by the splitting of Pangaea, which was what the continents were called before they split up into different landmasses. The splitting of Pangaea caused massive earthquakes and volcanic eruptions, which gave way to a large extinction. No such global event took place during the transition between the Jurassic period and the Triassic period.
The end of the Jurassic period is marked by what scientists call “The Great Extinction.” Many theories exist as to how this extinction took place, but some evidence suggests that it was due to plant decay. The creatures that survived during this transition included bugs that fed on dead organisms and mammals that fed on insects.Learn more about Dinosaurs
There are numerous theories regarding the extinction of the dinosaurs, including the triceratops, at the end of the Cretaceous period. The most prevalent theory describes the sudden destruction of the dinosaurs, and 50 to 75 percent of the planet's flora and other fauna, being due to a huge asteroid impact that dramatically altered the environment. However, despite strong evidence, there is no conclusive proof, explains the Smithsonian Institution.Full Answer >
Because dinosaurs are classified as reptiles, one might assume that they are cold blooded, but some scientists suggest that dinosaurs may have been somewhere between cold and warm blooded. Though most animals fall into either category, there have been some intermediary species known to science, with dinosaurs potentially being one of this number.Full Answer >
The velociraptor became extinct at the end of the Cretaceous Period due to an asteroid strike at the Yucatan Peninsula that occurred roughly 65 million years ago. This extinction event, known as the K-T boundary, also killed all other known species of non-avian dinosaurs.Full Answer >
The end of the dinosaurs is one of the greatest mysteries of paleontology. The leading theory of their extinction involves a massive meteor impact, possibly the one that created the Chicxulub crater in Mexico. Alternative theories include multiple global impacts, a sudden change in the sea level and a worldwide increase in volcanic activity that drastically altered the atmosphere and global climate.Full Answer >
