like mammals and others birds‚ warm blooded. Dinosaurs are creatures that lived on Earth around 251 million years ago. Dinosaurs lived in the Mesozoic Era. This era contained three separate subsections: the Triassic Era‚ the Jurassic Era‚ and the Cretaceous. When the Mesozoic Era ended‚ most or a majority of the dinosaurs were extinct due to a catastrophic event that is still unknown to us today. Dinosaurs walked in an upright position‚ some dinosaurs used two legs‚ other used four to walk and move

origin of the park reveals that it was deposited in layers. The layers are composed of sediments such as sand‚ silt‚ and clay that have been cemented to form sedimentary rocks. The sedimentary rocks in this area were deposited during the late Cretaceous Period which was 67 to 75 million years ago. Deposition and erosion are geologic process that created the formation of The Badlands. Some of the formations that took place at the Badlands National Park are: • The Sharp formation is light in color

North Australia experienced warm weather and South Australia experienced cool weather. Tasmania became covered by water due to sea levels rising and ice caps formed in Antarctica‚ Evidence of this can be found through the carbon dating of ice caps that can be dated back to the cretaceous period.

Dinosaurs lived on earth 65 million years ago. They lived on the earth much before any human being was born. They ruled the earth for over 165 million years‚ till 65 million years ago. They were huge monsters‚ even bigger than elephants. The word "dinosaur" was taken from a Greek word which means terrible lizard. But they weren’t exactly lizards. Lizards are one type of reptile and dinosaurs are another type. Not all dinosaurs were giants. Some dinosaurs were no bigger than small dogs. The smallest

The term “dinosaur”‚ was coined in 1982 by Richard Owen and was meant to refer to dinosaurs’ impressive size rather their scary appearance. Dinosaurs are considered to be the biggest animals to ever walk on Earth. They lived on every continent‚ including Antarctica

called the Age of the Reptiles. This era was split up into three sections‚ the Triassic which was from 245 million years ago to 208 million years ago‚ and then the Jurassic which was 208 million years ago to 146 million years ago and finally the Cretaceous period which lasted from 146 million years ago to 65 million years ago when dinosaurs started to die off. Over many years scientists have developed many different

small arms: that they were simply a vestigial organ and served no useful purpose. While this idea floats through popular culture‚ paleontologists remain skeptical; it seems unlikely that this feature of theropod dinosaurs would persist into the late Cretaceous period if they served no purpose‚ especially with the muscle and capabilities these arms had (Strauss 2017). The writers of Meet the Robinsons most likely chose to represent the function of Tiny’s arm in this way because it fits comfortably in the

The legend of the Chupacabra begins in March‚ 1995 in Puerto Rico and since its initial report there have been multiple sightings worldwide‚ the majority being in Latin America but also including: The Philippines‚ Russia‚ China‚ Thailand‚ and even lower parts of the US like Texas and Florida.

that the fossils were of a giant lizard-like animal which he named Megalosaurus bucklandii. Geologist James Parkinson decided that the creature “should be called ’Megalosaurus (Megalos‚ great; saurus‚ a lizard)’ (Delair and Sarjeant‚ 2002‚ p. 192)”. The discovery took the science world by storm. Other scientists‚ like Georges Cuvier‚ soon identified their own fossils as new species of animals similar to the Megalosaurus and the Quarterly Journal of the Geological Society of London where Buckland

Who wouldn’t‚ what with the exotic sea creatures and land creatures that lived in those times and would eventually become extinct or evolve to the animals of today?
