Cretaceous

Firstly, the rainforest’s wildlife demonstrates earth’s 8 evolutionary stages: The “Age of the Pteridophytes”, the “Age of the Conifers and Cycads”, the “Age of the Angiosperms”, along with the seperation of Gondwana, biological evolution and radiation during thirty-five million years of isolation, the beginnings and radiation of songbirds, the integration of Australia and Asia flora and fauna, and finally the tremendous effects of the Pleistocene glacial periods on tropical rainforest vegetation

The eras are the largest of the scale divisions. The major eras were Paleozoic era, Mesozoic era and the Cenozoic era. Among these the Mesozoic era is also called the age of reptiles and is divided into three periods: The Triassic, Jurassic and Cretaceous. The Jurassic period was dominated by dinosaurs. They ruled the land, sea and the air during this period. They were like the kings. ‘T-Rex' means Tynnosaurus rex, most ferocious of all the dinosaurs. The name means tyrant-lizard king. It was so

Era. This is one of the newest species of dinosaur that had been recovered. Its fossils was estimated to be at around 125 to 130 million years old. This bring us to a conclusion that Zhenyuanlong Suni exist during the Barremian Stage of the Early Cretaceous Period. Zhenyuanlong Suni was among the many other reptile and dinosaur fossils in the Yixian formation. The Zhenyuanlong suni is a recently discovered dinosaur in Northeastern China. It was found in sedimentary rocks in the ancient lake beds

Why did all the dinosaur die forever and what killed them? Some scientists claim that most dinosaurs died out simply because they didn’t mange to adapt to the changing climate. Dinosaurs been died for over 65 million years ago. We know there are little dinosaurs still called lizards, alligators, and more. Some people ask what does the word dinosaur come from? It was originally defined to mean “fearfully great lizard” by Richard Owen in 1942. The Greek word dinos, when used as a superlative, means

Dinosaurs were huge animals that existed in the past (Triassic period). Species came in different sizes and forms. Some had huge bodies while other tiny bodies and shape. From historical evidence prevalent today, dinosaurs were found in all continents but differed in sizes and physical attributes. The landmass prevalent in different regions denoted the type of species that existed within its boundaries. Some Dinosaurs were herbivores; therefore their teeth and digestive systems were developed

worked by their little brains. 4. Due to starvation. 5. Due to environmental change. 6. Due to Supernova that showered the earth in radiation. 7. Due to iridium-enriched mud. • Extinction- Still a theory. The K-T event, or the Cretaceous-Tertiary extinction event, is the name given for the vanishing of the dinosaurs and different species that took place about 65 million year back. For ages, scientists believed that this event was caused due to the atmospheric and topographical changes

My favorite period was the combination of the Triassic, Jurassic and Cretaceous periods. These periods are referred to as the Mesozoic Era. I loved these eras in particular because these eras dealt with basically nothing but the dinosaurs. I have always been fascinated with dinosaurs, and the fact that such huge animals were just wiped off the face of the earth. After the 5th mass extinction, no dinosaurs survived. Dinosaurs were very unique creatures, and there has not been any like them since this

The K-Pg event, the day life on earth was wiped out, is one of the most notorious extinctions in the history of the world. From jawed fish, to plants, to crocodyliforms (10 species’ fossils have been found, 5 of which are extinct), even a species of pterosaurs, life was extinguished; however, what happened to the creatures? What truly killed the dinosaurs? There are many theories but some ideas are downright insane. Some older ideas consist of comets dusting the Earth with a poisonous gas, or the

In the article “Skin Pathology in the Cretaceous: Evidence for Probable Failed Predation in a Dinosaur” written by Brice M. Rothschild and Robert Depalma, they report their findings on the observation of the skin of a duck billed dinosaur regarding its’ scaled pattern and forming of scar tissue (Rothschild and Depalma 2013). Rothschild and Depalma introduce the issue of dinosaur skin pathology through the finding of damaged dinosaur skin through Lingham-Soliar ‘s (2008) report on the damaged skin

separate continents during the Early Jurassic Period (around 200 million years ago), and dinosaurs would have seen great changes in the world in which they lived over the course of their existence. Dinosaurs mysteriously disappeared at the end of the Cretaceous Period, around 65 million years ago. Many other types of animals, as well as many species of plants, died out around the same time, and numerous competing theories exist as to what caused this mass extinction. In addition to the great volcanic or
