The Paleozoic era age approximately 300 million years (542 mya to 251 mya). This time period consists of two of the most important events in the history of animal life. In the beginning, multi celled animals underwent a dramatic explosion in diversity, this resulted in almost all living animal phyla appearing within a few million years. At the other end of the Paleozoic, it withstood the largest mass extinction in all of history. This event wiped out approximately 90% of all marine animal species
The Permian Time frame was the last time of the Paleozoic Time. Enduring from 299 million to 251 million years back, it took after the Carboniferous Time frame and went before the Triassic Time frame. By the early Permian, the two-extraordinary mainland’s of the Paleozoic, Gondwana and Euramerica, had crashed to frame the supercontinent Pangaea. Pangaea was formed like a thickened letter "C." The best bend of the "C" comprised of landmasses that would later wind up present-day Europe and Asia. North
I chose the Mummy Cave because I love Wyoming, my home state. Upon searching I found the Mummy Cave which is a rockshelter or better known as a cavern which is on the left bank of the North Fork of the Shoshone River in Park County. The findings from Mummy Cave have momentous import for the description of western American prehistory. Archaeologists reveal Mummy Cave was occupied for over 8,000 years from 7280 B. Results of the Mummy Cave investigations were published in Science in 1968. The excavation
Thrinaxodon was one of the descendants of the survivors of the Permian extinction and serves as one of the most well and understood transitional fossils from the early Triassic; Robert Broom became famous for finding specimens of early hominids in South Africa. Archeaocete whales had nostrils on the end of their snout rather than a blowhole like modern whales and dolphins; Leigh Van Valen pointed out archeaocete whales had blunt triangular teeth similar to land dwelling, hoofed mesonychids. Pezosiren
The mammoths have captured our imagination for many years; however the exact cause of how this incredible species died out is still not completely understood. The last Mammoths roamed the earth just over 3000 years ago, meaning they brushed shoulders with our early ancestors. There are two main schools of thought with regards to the extinction of the mammoths; one being that humans living during the time of the mammoths hunted the species into extinction, and the other citing climate change as the
100,000 years ago, the woolly mammoth (Mammuthus primigenus) roamed the Earth. The woolly mammoth is one of the most studied megafauna of the Pleistocene epoch, which spanned from 2.6 million to 11,700 years ago. Most populations of it died out around 10,000 years ago [4], although a small population survived until around 3.7 thousand years ago on Wrangel Island [6]. The woolly mammoth was one of the many now-extinct megafauna that existed during the Pleistocene. Others include the cave lion (Panthera
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

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
For many years people have debated the existence and time of the dinosaurs. Evolutionists have used dinosaurs against Christians in many arguments as one of their main weapons. Many Christians give up when this argument is made and believe in theological evolution, or evolution in general because the Bible does not give them any support on this topic. There is several times where dinosaurs are mentioned in the Bible but it is shrugged off as make believe because the word dragon is used. There is
