  • The Importance Of Transportation In The Cretaceous Period

    1. Short summary of the history At 145 ± 4 to 66 million years (Ma) ago, Cretaceous period was the last period of the Mesozoic Era, right after Jurassic period and followed by the Paleogene period of the Cenozoic Era (International Commission Chart, 2014). 'Creta' in Latin means chalk and this is due to the large amount of calcium carbonate deposited by shells of marine animals thus resulting in large quantities of chalk (American Geological Institute, 1972). The shifting of continents as the result of the separation of the world-continent Pangaea continued on in the Cretaceous period that led to evolution of life on land and creation of new coastlines as well as an increase in the floras and faunas with the evolution of forest (Waggoner, 1995). 2. Geography Figure 1. Image of Cretaceous Map (Scotese, 2003) It is recommended to start your journey from North America and travel east to Eurasia and China as these continents are nearer to each other, thus easier to transport from one place to another especially if you are on a shoestring budget. North America has a great diversity of dinosaurs; more than 100 types of dinosaurs dominating the land. These dinosaurs can be herbivores, carnivores or omnivores. From North America, you may travel east to Eurasia and then down to China where you will be able to see and encounter more dinosaurs and flora and fauna. It is interesting as you move along because the features and characteristics of dinosaurs living from one place to…

  • Biological Big Bang Theory

    The Cambrian explosion is referred to as “Biological Big Bang” (Science News) or “Evolution’s Big Bang” (Science) (Levinton, J. S.1992), because of the unexpectedness presence of animal life in the Cambrian. Figures have it that it started back 542 million years ago and terminated approximately 40 million years later. This era is marked by the emerging of profuse skeletonized metazoans, an abrupt intensification in biodiversity and the appearance of most modern lives (Von Bloh 18). Animals that…

  • Cambrian Explosion Essay

    Cause of the Cambrian Explosion is an article that argues for a combination of factors that lead to the mass growth in animal population 541 million years ago. According to Smith and Harper, scientists have been proposing hypotheses on the cause of this event since the dawn of science. Hypotheses range from explosions in space to “intrinsic genomic reorganization” and many others. Most current ideas fall into three categories. They propose that, “The rapid diversification of animals in the…

  • What Is Camblosion?

    The Cambrian explosion is perhaps one of the most impactful events in evolutionary history, it gives way to present day animals in fossilized forms which we now use to understand a time period that was much more complex. The period occurred 535-525 million years ago, and was a time where the majority of animals were soft bodied and appeared to be grazers, suspension feeders as well as scavengers. The Cambrian explosion occurred and with it extinctions of many of the soft bodied animals. Those…

  • Great Unconformity

    formation of the Great Unconformity. For example, the average 87Sr/86Sr of sea water increased during the Neoproterozoic (Fig. 4). This long-term signal is attributable to the increasing concentration of 87Sr in continental crust due to the decay of 87Rb, and to the long-term erosion and progressive exposure of 87Sr-rich granitic rocks required to form the Great Unconformity. During the Cambrian, 87Sr/86Sr increased more rapidly to achieve a 900 Myr maximum (that is, a maximum over the past 900…

  • Ercall Quarries

    The Ercall Quarries were visited on October 21st, 2017. It is an important geological site and is part of the Site of Special Scientific Interest (SSSI). The Ercall sometimes known as the Ercall Hill, is a small hill in the county of Shropshire, England. The site includes 540-million-year-old ripple beds and ancient pre-Cambrian lava flows in exposed quarries. There is a M54 motorway near the Quarries, giving it easy access to the Quarries. The motorway was constructed in 1974, near the northern…

  • What Is The Precambrian Period?

    To start off the exhibit is the Precambrian period. The Precambrian period lasted for 4 billion years. Scientists believe that this period where 90%of earth's history was discovered. Life first started evolving, and progresses and changed the planet. Scientists discovered the truth about organic compounds, the first prokaryotic cells and the first meteorites to hit the earth. Scientists believe that some of these meteorites gave rise to organic compounds, or life's building blocks. The Cambrian…
