Fossil

Recently, scientists have discovered fossils of an extinct species of turtles that particularly have snouts as noses, similar to a pig. However, because of its snout, it was named Golden's bacon turtle, or Arvinachelys golden. Usually, turtles have one nasal passage in their skulls because of how fleshy their nostrils are. Arvinachelys golden was found by a team from Natural History Museum of Utah and discovered the fossil at the Grand Staircase-Escalante National Monument. In addition, this…

Imagine finding fossils of an undiscovered sauropod while adventuring with some friends. Well that is what happened to Elmer S. Riggs. He discovered the first fossils of the Brachiosaurus. In 1900, Riggs found a partial skeleton of a Brachiosaurus in the rocks of the Brushy Basin Membrane of the Morrison Formation. The fossils were studied and information on this species was revealed. Brachiosaurs lived in the late Jurassic period, which was about 145 to 156 million years ago. The Jurassic…

effects of new energy sources. Martin V. Melosi portrays a rapid ideological change about how the United States’s energy choices influence the federal government to assert actions, in his article “Energy and Environment in the United States: The Era of Fossil Fuel”. Melosi argues that one of the most common beliefs in the late 19th century was that smoke signified luxury. It’s not unusual to belief that the nation yielding the highest amount of resources, or is able to acquire them, is better.…

variety of evidence that supports evolution. By studying the fossil record, comparative anatomy, genetics and natural selection scientists have been able to support Charles Darwin’s theory (evolution). This report will focus on evidence from the fossil record as well as genetics. The fossil record is the collection of information that shows the occurrence and evolution of living organisms through geological time from fossils. A transitional fossil is the remains of an organism that is thought…

1. The movie Life on Earth focused on how fossils are glimpses of a distant past because they explain how life evolved on earth. They also used a Cladogram to explain the cladistic relationship between a number of species. The first organism with a nucleus lived one and a half million years ago. An animal with a braincase and a beginning of a backbone appeared 500 million years ago. Amniotes were split into two main lineages. One is identified by a hole that evolved in the skull behind the eye…

The passage on the body temperatures of the dinosaurs dictate that dinosaurs were endothermic animals. Three reasons are being given for this arguement: existence of dinosaur fossils in polar region, the leg position of the dinosaur and the haversian canals in the bone structure of the dinosaur. The fossils that have been founded in the polar region is being classified as a clear indicator for endothermy in dinosaurs. However, the lecturer confronts this point by highlighting the climate in the…

The first theme that impressed me in this book was the comparison of everyday math and evolution. This idea impressed me because the topics of math and evolution are usually never discussed together. After reading about this topic, where Carroll placed math and evolution together into one theme, I do agree with him on this idea. He suggests that chance is involved in evolution over time. I like this interpretation because it makes sense that it is almost up to chance when a certain heritable…

activity and settlements. Stratigraphic excavation is the study and recording of different strata as they are removed from the area. Index fossils are a large help to the stratigraphy dating method. An organism such as venericardia planicosta existed only during the Eocene time period, so everytime we find one, we can assume that the rocks containing the fossil and similar artifacts must have belonged to the Eocene era. Style analysis as a dating technique is based upon the fact that the shape…

Rhonda Moore Bio/ Lecture 1101 D957 October 2, 2016 Radioactive Dating A) Any method of determining the age of earth materials or objects of organic origin based on measurement of either short-lived radioactive elements or the amount of long-lived radioactive element plus its decay product. Example: B) Look at the diagram below which represents the radioactive decay of uranium- 238. The shaded area represents the decay product which is lead-206. The half…

passage states that dinosaur fossils have been found even in polar regions. This shows that dinosaurs might have been able to regulate their body temperature. However, the lecturer contradicts this point by arguing that polar regions when dinosaurs existed were much warmer than today, and when the regions were ice-cold during winter, dinosaurs might have been able to migrate to warmer areas or hibernate like modern reptiles. Therefore, the presence of dinosaur fossils in polar regions does not…
