Fossils Lab
Name: Jewel Ward ID: 812004483 BIOL 2262- Evolutionary Biology Lab # 3 – Fossils Aim: To study fossils and the sedimentary layers they were found. Examine the clues left to appreciate the species found and the characteristics of the environment at the time when the organisms died and became fossilized. Introduction: Fossils are the remains of organisms that are formed when those organisms died and become buried in such a way that the decaying process was slowed down due to environmental conditions. E.g. fine suspended sediment particles in water, tar pits, bogs, ash from volcanoes, amber, ice, sand blown by the wind. Most fossils have hard body parts that are more resilient to decay and are usually aquatic. Fossils can be sorted into two
Mya Seaway Research Paper
1677 Words | 7 PagesThis layer of the Niobrara contains much evidence of life of vertebrates and aquatic life, including birds. The limestone layer is a thick layer of limestone separated from the chalk layer by shale. The limestone layer also contains many fossilized remains, but is best known for having marine reptiles that have been preserved rather well. The currents from the different seas as well as the draining of surface water into the seaway were important in the formations of these layers and the fossilization of marine life (Colorado Parks and
Riversleigh Fossil Site, Australia
2212 Words | 9 PagesRiversleigh Fossil Site, Australia Geological History Riversleigh covers an area of approximately 80 square kilometres and is located 250 km north-west of Mt Isa.

Stinky Cove Research Paper
1724 Words | 7 PagesWe walked along the beach a little more and talked and looked at the location of a whale skull that used to be buried in the sand. The rock was actually much smoother than . We also took a look at some possible bones and skeletal remains along with concretions. The concretions were rather large comparable to smart car in size. Concretions are solid masses formed around some type of matter that will change the chemistry of the rock slightly, helping it become harder and less susceptible to erosion.
Cordell Formation
1484 Words | 6 PagesThe fossils which can be observed include brachiopods and rugose corals. Specific species of corals have been identified in Bellapenna’s report since they are the most widespread fossil within the Cordell dolostone. The interbedded chert can be observed in the field. The gradation of gray to blue to brown chert nodules can also be observed. Bellapenna also suggests there are quartz and garnet grains within the Dolostone.

Inner Fish Discussion Answers
754 Words | 4 PagesElla Aerts Period 5 Your Inner Fish Discussion Answers Chapter 1 - Finding Your Inner Fish Neil and his colleagues focused on rocks from 375 million years ago because fossils from 360 million years ago were amphibians with necks and four legs. However rocks that are 380 million years old looked more like fish we know today, with fins and scale. So, it made sense that they would find the transitioning fossils in rocks that was 375 million years old.
Susquehanna River Lab
627 Words | 3 PagesThe Honors Earth Science classes went to the Susquehanna River to solve a problem. The problem was not knowing if the is healthy. The classes want to know if the river is healthy, because the students live near the river, and it affects the classes everyday lives. To answer the problem, the classes did a series of tests, and made physical observations at various islands in the river. The students used test kits and other tools to test pH, temperature, phosphate, nitrate, turbidity, and dissolved oxygen.
Mystery Powder Lab
646 Words | 3 PagesUse the evidence provided by the tests to identify the mystery powder. The mystery powder (#5) is the baking powder. My partners and I figured this out because the physical and chemical properties of both of the substances are very similar. For example, both powders are not soluble in water, and they both turned red when they reacted with the universal indicator.
Assess The Argument That Fossils Are Evidence Of Evolution
745 Words | 3 PagesOne of the main arguments that Darwinsts use is the argument that fossils are evidence of evolution. I have gathered information from Your Inner Fish and internet sources. I found an article online that says in a nutshell; there 's two lines of evidence for evolution. The first line of evidence concerns the order in which fossils are found buried. Fossils are generally found buried in a sequential order.

Presences of normal and thrust faulting in the outcrops indicate the formation underwent multiple episodes of deformation, including both compressional and tensional stresses. The Blakeley formation was deposited as a submarine fan in a tectonically

Ammonites Research Paper
447 Words | 2 PagesThe fleshy body would soon decompose, or eventually get eaten up by other sea creatures, however, the shell would remain there for a lot longer. Over time, the shell would be buried by layers of silt and sand. After thousands of years, once the shell was buried very deeply, the shell would begin to decompose, however, the space in which the shell was originally, would leave an empty space that would eventually get filled up by water that was rich in minerals and would then turn to stone. Leaving us with a fossil. This is named ‘permineralisation’.
Stephen Jay Gould Sex Drugs Disasters And The Extinction Of Dinosaurs
1128 Words | 5 PagesEndless theories and hypothesis’ surround the disappearance of the dinosaur species. Comets, asteroids, disease, and volcanic eruptions are just some of the presumed causes of their extinction. Which one is to believe? In “Sex, Drugs, Disaster, and the Extinction of Dinosaurs,” Stephen Jay Gould presents three proposals for their extinction: Sex, Drugs, and Disasters. Gould explains the three theories on the extinction of dinosaurs by giving a biologic and scientific reason for each, with the purpose of showing that scientific discoveries come from testable theories.
Paleopathology: Hominid Fossils
240 Words | 1 PagesThere has been a high amount of hominid fossils that have been discovered over the years. Scientist always continues to find information to show the way species died and recognition of who they were by the shape of the bones with the archaeological records. But yet, I wonder what other methods do scientist used to find an extended record of information on a species. I believe the study of Paleopathology influences with helping on the recognition of fossil bones, as it is the study of the fossil anthropology (Lewis, et al., 2013). Other and not just the time and the form of the bones discover there’s more, such as; the fossils surroundings, and the place where the fossil was found.
