Burgess Shale Research Paper

The rotting away of different types of life forms is important in the cycle of life. Soft tissue can be broken down with no evidence that it ever existed at all. How crazy is that something that is alive for at least ten years, will leave this Earth without leaving a trace behind. I think that that is insane. How is there no memory of a life form? The hard parts like the wheel, bones, and teeth will remain because it has already been layered with minerals which will preserve it. Extinction is based on shallow marine shells. All of the marine wheel look very different, and can be broken up into different categories. Specifically the Cambrian Burgess Shale is a marine animal which is preserved by minerals. Therefore when it does eventually die, there would be evidence left behind.The beeches Trilobites Ordovician bed 4 centimeters thick is 4 centimeters thick and grows towards the upper Ordovician. …show more content…
That is the key to finding these animals.. Triarnthrus and Cryptolithus are the most common Tribolites found in upstate New York. Their limbs were preserved in pyrite. Today pyrite is actually formed after marine shield. Pyrite is made through the production of sulfate which produces bacteria. Beecher realized that you can erase the shale lines with erasers. Details can be revealed through x-ray machines. John Cisine discovered this method with the loss of material by Beecher. When Beecher dies in `904, he left his work unfinishedd. The most abundant trilobitee was Triarthus. It displayed the first details of a muscularite. Then in 1981, Whitely and Coope re-discovered Beechers Triarthus. More of these beds were discovered and searched for answers. Another key element to pyrite was that it was radio active and have low amounts of
