Barry The sculptured landscape of western I'tali contains exposures of sedimentary rock which are prolific with traces and remains of prehistoric life known as "fossils." THE SEMIAR1D CLIMATE oi the Great Basin discourages the establishment and growth of plant life, consequently the processes of erosion are free to sculpture the laire rock into ledges, caves, canyons, and ridges. The Great Basin has had various geological periods of inundation, mountain uplifting, folding, and faulting. Because of these geological processes, older rock layers or strata are often liften upwards and folded over more recent or younger layers. For this reason, it is common to find the oldest fossils lying mi the surface of the earth or even high on a mountain alxive more recent ones. Geological maps diagramatically reflect these disconformities. In contrast, the Grand Canyon presents to the oliserver a nearly perfect, uninterrupted sequence of time throughout it's layers of sedimentary rock starting with the Cambrian at the liottom of the canyon to recent layers at the rim, representing about 550 million years of erosion. A short mule ride from the rim to the Colorado River will span nearly the whole fossil record of the earth. Each group of fossils lived its time upon the stage, later to lie discovered, if his liody parts and environment favored preservation. Some groups have survived for very long periods while others have had a relatively short life span. As an example, the dinosaur group appeared during the Triassic and disappeared in the Cretaceous period, a lapse of only 150 million years, while the Algae have lived from the Cambrian to the present - a period exceeding 550 million years. The geological dating of these rock exposures of the Great Basin reveals that they range in age from early Cambrian to recent. Some of the common fossils in this area of Utah and their present day representatives are the trilobite (crab), gastropod (snail), horn coral (corla), brachipod (scollop), pelecepod (clam), and cephalopod (squid). There is a very close resemblance among some of these forms and a sharp contrast among others. The king crab looks very similar to some species of trilobite fossils, and million years. certainly the snail has changed very little in HOW DOES ONE recognize a fossil? The commonly encountered fossils are relatively easy to recognize after an introduction to the common forms. The neophyte should look at collections of local collectors, collections at local universities and museums, and visit the rock and fossil displays in the community. This will help you to recognize a fossil when you see it in the field. There are also numerous booklets and books on rocks and fossils as well as a few popular periodicals.

Assuming that we recognize a fossil in the field or that we are with someone who can, the next step is to locate the rock section, layer, or strata which contains the type of fossils which is sought. These strata can lie located on geological guidebooks and maps of the area or from communications with local SEANS PEAS geologists and amateur collectors. The Slieelcr Shale formation at Antelope Springs near Delta is the most famous for collecting triloliites. Other rock formations will also yield interesting fossils. The geological maps of this nn Hunt's defidsw area, which are available at the University of Utah and Brigham Young University, show the exact location of various formations which are popular for collecting. Members of the Dugway Gem and Mineral Society have copies of these maps, and the Society maintains a collection of numerous guidebooks cm the geology of this area. A few suggestions are appropriate for those who are new to this hobby and plan to venture into the field and collect. In addition to the necessary items of clothing and food, the fossil collector should have a rock hammer, chisel, specimen bag, and a notebook to record the collecting area and any other pertinent information which will aid you in identifying your fossil. Before venturing into the more isolated areas, ask yourself a few questions, such as: Do I have enough water and gas? Does someone know where I ain going, and when I plan to return? Do I have a first aid kit? Having planned for these items, you will enjoy your trip and not worry alxiut what you should have done. Take advantage of this excellent locality, and introduce your family to healthful and gratifying experiences in the great outdoors. NO. 303 NO. 303 CANS NO. CANS CANS Cl FLOUR asr.
