The name dinosaur translates as 'terrible or wondrous lizards' and they certainly evolved in a huge range of sizes and shapes, from the gigantic plant-eating sauropods to the quick meat-eating tyrannosaurs. So far, the remains of over 1,000 different dinosaur species have been identified from fossils the extinction of most dinosaurs species occurred in the Cretaceous-Tertiary Extinction event. Fossil records show that birds evolved within the Theropod dinosaurs during the Jurassic period. Some birds survived the Cretaceous-Tertiary Extinction event from which modern birds
The pyramid is also the tallest man made structure for over 3800 years, and was later surpassed by Lincoln cathedral. The pyramid is a tomb built for the fourth dynasty Egyptian king Khufu, and that is why the pyramid of Giza is also called Khufu’s pyramid or the pyramid of Khufu. Khufu was remembered as a very ruthless king, but he is also remembered as the builder of the pyramid. The pyramid was built just under 30 years, used about 2 million blocks of stone, each blocks weigh 2.5 tons, and how did they move them from 500 miles away? Well a lot of people belief that sloping ramps built out of mud, stone, and wood were used as transportation.
The animal I chose to do my report over for the prehistoric era is the Stegosaurus. Stegosaurus translates to meaning, “roof lizard or"plated lizard". Stegosauruses most likely lived during the late Jurassic period, about 156-140 million years ago. Fossils have been found in Colorado, Utah, and Wyoming, USA, and in North America, western Europe, southern India, China, and southern Africa. The first Stegosaurus fossil was found in Colorado, USA, in 1876 by M. P. Felch.
Java man was the “missing link”, he proclaimed. All over the world, people started to hunt for traces of our distant ancestors. With every new fossil they found it became ever clearer that there was not just one “missing link” but a whole chain of them between apes and modern man. Comparison of the fossils that Dubois found on Java in the nineteenth century with other finds from Africa has revealed that what Dubois found was actually a Homo erectus. In 1972 Mary Leakey’s son, Richard, and Alan Walker were looking for fossils near Lake Turkana in Kenya.
Daniel T*** Candidate Number- 71** Centre Number- 443** What Killed The Dinosaurs? Contents Page Front Cover ………………………………………………………………… 1 Table of Contents ………………………………………………………… 2 Introduction ……………………………………………………………….. 3 Scientific Background ………………………………………………….. 4 Argument for What Killed the Dinosaurs ……………………….. 8 Arguments Against this theory ……………………………………… 10 Introduction So then, the big question is what killed the dinosaurs? For around 200 million years dinosaurs had ruled the world, they had grown huge in every environment. Then around 65 million years ago, they suddenly disappeared from the fossil record. What lead to their extinction will be discussed in this case study.
Khufu’s Last Wish Three monolithic structures stand in testament to great kings of old in the vast necropolis of Giza. Known to us as pyramids, they were built in 2560 BC, known to us it stands at 140 meters tall, known is that upon completion these colossal structures were incased within an integument of limestone. Unknown however is why the Egyptians had built this monument to their God incarnate king. It was initially believed that the Pyramids were constructed with a plethoric assembly of slaves, In fact Herodotus wrote of seeing 100 000 slaves straining themselves at the mercy of a whip man, this group would be relieved by another group every annual quarter. This recount however is rife with discrepancies as King Khufu - 4th Dynasty ruler of Egypt - the royal responsible for the commissioning of the Great Pyramid, did not have a vast body of slaves at his disposal, and even if he had, there was no way that 100,000 could work simultaneously on one pyramid.
They sleep, eat, and breed on the branches. Unlike most mammals, koalas never make dens or permanent homes. They do have home territories, but they will not stay in one particular tree. The koala is an arboreal animal. Arboreal means “living in trees”.
It is overtly known that the humans’ brain is the most complex in respect to any other species. Since the emergence of the first species in our Homo habilis about 2 million years ago, the brain doubled in size, and compared to our earlier ancestors from about 4 million years ago it is now three times larger. The average size of the modern human adult brain is about 1350 cc. The brain of the walking ape/man of 4.5 million years ago, was about 400 cc in size, and the first human brain about 2 million years ago was about 575 cc. Ascending from lower life forms, the human brain emerged through the natural selection process from randomly occurring changes to make the brain in which we have today.
The pyramid of khufu stands 481 feet high, measures roughly 756 feet on each side and cover 13 acres of land it is the largest of ancient Egypt's 70 pyramids, if the blocks that form the pyramid were reduced to foot-sized square cubes and lined up, the cubs would stretch for 16,600 miles. originally the great pyramid was covered by casing stones that formed a smooth outer surface, consists of more than 2.3 million limestone blocks the largest granite stones in the pyramid found in the king's chamber weight 25 to 80 tonnes and were transported more than 500 miles away from aswan, two types of limestone were used for construction, A soft limestone either pure or nummulitic was used for the bulk of the core blocks and a hard white limestone for the mantle. The four faces of the pyramid are slightly concave, and it is the only pyramid to have been built this way. Contemporary experiments have demonstrated that the copper chisels and stone hammers used by workers were sufficient to chip away at limestone, Tests have determined that 2.5-ton limestone blocks can be transported a fair distance in a
The origin of this wonderful mechanism is one of evolution's most durable mysteries. In 1861, just two years after Darwin published Origin of Species, quarry workers in Germany unearthed spectacular fossils of a crow-size bird, dubbed Archaeopteryx, that lived about 150 million years ago. It had feathers and other traits of living birds but also vestiges of a reptilian past, such as teeth in its mouth, claws on its wings, and a long,
