Many asteroids of this type are now known; their orbits pass through the inner solar system and cross Earth's orbit. Some of these could potentially hit Earth in the future download. This puts it at 4 degrees Celsius higher than the average temperatures that we experience in this modern age. The warm climate meant that sea levels rose. This meant that a number of lakes and seas inland began to appear. Many of these locations, the Gobi Desert in Mongolia for instance, are nothing more than dry land in the modern age.

Many wild ideas about how the dinosaurs were rendered extinct were presented over the years. 1980: Few satisfactory answers to the mystery behind the extinction of dinosaurs were offered until 1980, when a group of scientists at the University of California at Berkeley — Luis and Walter Alvarez, Frank Asaro, and Helen Michel — proposed a stunning and convincing mechanism for the "K-T extinction" (meaning the extinction of dinosaurs at the boundary between the Cretaceous period (K) and the Tertiary period (T)) The Illustrated Encyclopedia read here Its back and tail also had a series of weird, fist-sized bumps, each one holding a nipple-like structure which has yet to be explained by scientists. These structures may very well be anchoring points for porcupine-like quills, like those found on Triceratops’ older cousin, Psittacosaurus. Or perhaps, some scientists suggest, they were poison glands, oozing toxins to protect the Triceratops’ hindquarters from T-Rex attacks , cited: Digging Dinosaurs: The Search download online download online.

The herbivorous sauropod dinosaurs of the Jurassic and Cretaceous periods were the largest terrestrial animals ever, surpassing the largest herbivorous mammals by an order of magnitude in body mass.
