Cambrian

Burgess Shale The Burgess Shale was first discovered in 1909 by a Paleontologist named Charles Walcott and is believed to be over 500 million years ago in Middle Cambrian. This geological formation was first found near a mountain by the name of Mount Burgess, for which it was named after, in Canada. Similar formations have been uncovered in China, Europe, USA and many other places around the world. The Burgess Shale is one of the most important of fossil type formations due to the fact that they

INTRODUCTION: The Burgess Shale Phyllopod bed was discovered in the early 1900’s. This discovery was monumental in the field of geology. The Lagerstatten and its immaculate fossil fauna introduced geologists to the lost world of a Middle Cambrian sea bed. The unique imprint fossils of bizarre organisms like Pikaia, and Anomalocaris perplexed scientists for over a century. This was because of their preservation, but also because of their characteristics. These findings are much more than just

Mary Owen Professor Christopher Pantazis BIO 102 23 March 2017 Uncovering the Mystery that is Hallucigenia For many years, little was known about the strange creature that is Hallucigenia sparsa. It wasn’t until Dr. Simon Conway Morris discovered its 508 million-year-old fossil in a part of the Burgess Shale Formation in Canada that we were able to discern that Hallucigenia isn’t as mysterious as once thought (Zimmer p. D4). In 1977, Dr. Conway Morris wasn’t the first to discover the animal, but

Ammonite taxa often occur in narrow time ranges, arguably making them the best index fossils to determine the ages of strata of certain time intervals (Callomon, 2003). The fossil remnants of ammonites act as the major basis for the identification of Jurassic and Cretaceous strata in the Sverdrup Basin, reinforced by the presence of bivalves, dinoflagellates, and foraminifera (Galloway et al., 2013). While macrofossils such as ammonites are used to define every stage of the Jurassic and Cretaceous

In 2005, Palaeontologist Mary Schweitzer and her team made the discovery of finding original soft tissue, including blood vessels, in a Tyrannosaurus Rex fossil in Montana. Many of Schweitzer's fellow scientists insisted that she had been mistaken because of previous theories of how fossils were preserved. The fossil was buried in a permeable sandstone, where groundwater could get in. Since organic material is quickly broken down in water, the soft tissue should have decayed quickly under the conditions

There are over 80 ghost towns in Oregon making it the best state for ghost towns. Some are populated but others are completely abandoned. Many are historic, some are mining towns, others are Indian villages, and several are haunted. A few of them are found along the historic Lewis and Clark trail and they all have a little something interested from Oregon’s early history. Some of the most known ghost towns are: Shaniko, Boyd, Dufur, Mayer, Lonerock, Danner, Kingsley, Bourne, Friend, Fossil, Spray

The bioregion of the Slate Belt is in the northeastern most corner of Northampton County Pennsylvania. This bioregion is unique to others in the region due to the Martinsville Shale deposits. These deposits contain high quality slate that when quarried and sold on the market, lead the industry in the United State for over 100 years. The industry in the south valley consists of cement plants due to rich limestone deposits and abandoned iron mines in the west for the now defunct Bethlehem Steel. To

Cambrian period 543-490 million years Introduction The Cambrian Period marks the beginning of the Paleozoic Era. This period gets its name from a place in Wales where the first examples of this type of ancient life was found. The period lasted for nearly 53 million years, from about 543 million years ago until 490 million years ago. The Cambrian Period marks an important point in the history of life on earth; it is the time when most of the major groups

such as the Cambrian Explosion. The Cambrian explosion was a macro-evolutionary event that happened during the late Ediacaran and early Cambrian period. It introduced a number of phyla on the Earth, and significantly affected the animal

The Evolution of Animals Eukaryotes come in two grades of organization: single-celled (protists) and multicellular (plants, animals, and fungi). The world today is full of complex multicellular plants and animals: how, why, and when did they evolve from protists? Proterozoic Protists A single-celled eukaryote or protist can carry chlorophyll (it can be an autotrophic, photosynthetic, "alga"), it can eat other organisms (it can be an organotrophic, "protozoan" "animal"), or it may do both
