The Sixth Extinction: An Unnatural History by Elizabeth Kolbert is a nonfiction book about the mass extinction happening around us. Kolbert proclaims that we are currently living in the middle of a sixth, man made extinction. During the last half a billion years the Earth has experienced multiple mass extinctions, where accelerated rates of change altered and contracted the diversity of life on Earth. While the past five extinctions have been caused by nature, this time, however, the sixth extinction

Introduction: What exactly caused the Pleistocene megafauna extinction? The exact reason for the Pleistocene extinction is still unknown, however the data presented below can be used to conclude why the Pleistocene extinction happened. The authors used data from the thickness growth rates of mastodon’s teeth and the condition of Pleistocene species’ teeth. This data can provide the answer to what caused the extinction, and if humans had anything to do with the extinction. Methods Section:

Three Major phases took place in the break-up of Pangaea due to Continental Drift. 1. First Phase. It began in the early middle Jurassic at about 175 million years ago, when Pangaea started to break away from the Tethys Ocean in the east of the pacific in the west giving rise to the supercontinents Laurasia and Gondwana. The breaking that took part between North America and Africa created multiple failed breaks. One break resulted in a new ocean, the North Atlantic Ocean. The Atlantic Ocean did not

The elasmosaurus was an aquatic plesiosaur of formidable size which existed in the Campanian stage of the Cretacious period. There are several distinct types of elasmosaurs, but for the purpose of this paper the focus will be on elasmosaurs that are non-aristonectine – or elasmosaurs not of the group Aristonectinae which were distinguished by their larger heads and shorter-necks. In this paper, I will discuss the discovery of existing fossils, the timeframe it existed in, the locations in which it

Lorenzo Fuchs Period 2 IB Biology Devunian Dalaconic Period -409 million years ago -Diversification of bony fishes, first amphibians and insects. In this scale/illustration we can observe that the scale places the time period (Devonian) after the Silurian period but before the Mississippian period and the Pennsylvanian period, both of which form part of the Carboniferous period. Not to mention we can observe the species which were dominant in this era. During this era it was the existence of

Biodiversity crisis of the Anthropocene epoch. The Earth’s history has been divided into eras, periods and epochs (geological time span) by geologists. The current era is called the Cenozoic Era which is subdivided into several groups with the most recent group being the Quaternary Period. The Quaternary period began 65 million years ago and was further divided into two epochs: the Pleistocene and the Holocene. The Pleistocene epoch was thought to begin 2.58 million years ago (Angus, 2016). The

There is few section of method of presenting the Dinosaur Program. The teaching social skills to young children must be fit with the children’s learning styles, temperaments and cognitive abilities due to the methods and processes given. There are vast of differences in children’s development abilities between the ranges of 3 to 8 years old. This is because some children in the group might be able to read but some could not and some will be able to grasp the relatively complicated ideas. This program

1) How are sedimentary rocks used to interpret past dinosaur habitats? How is the geologic principle of uniformitarianism used for this type of interpretation? Sedimentary rocks interpret dinosaur habitats through encased environmental structures of the past. Through sedimentary rocks, paleoecologists’ can examine the arranged formation of sedimentary structures to specify what type of environment the dinosaurs’ lived in. An example of a specific sedimentary rock structure can be seen through formed

As a child, my love for dinosaurs was huge. I was so interested by their size, their habits, and how all of their lives vanished one day. That is why my favorite book growing up as a kid was Danny and the Dinosaur. I loved this book not only because it showed pictures of the dinosaur, but because of how Danny and the dinosaur became friends. Danny wished that he could become alive and be friends with him. All of a sudden, the dinosaur starts talking! The messages I learned from this book as
