Dinosaur Valley State Park
Dinosaur Valley State Park is a state park near Glen Rose, Texas, United States. History Dinosaur Valley State Park, located just northwest of Glen Rose in Somervell County, Texas, is a scenic park set astride the Paluxy River. The land for the park was acquired from private owners under the State Parks Bonds Program during 1968 and opened to the public in 1972. In addition to being a state park, it is also a National Natural Landmark. Eastward-dipping limestones, sandstones, and mudstones of the Glen Rose Formation were deposited during the early Cretaceous Period approximately 113 million years ago along the shorelines of an ancient sea, and form the geological setting for the park area. Over the last million years or so, these layered formations have been eroded, dissected and sculpted by the Paluxy River which, in many places, has cut down to resistant beds and planed off sizable exposures of rock in the river bottom.

Paluxy River
The Paluxy River, also known as Paluxy Creek, is a river in the U.S. state of Texas. It is a tributary of the Brazos River. It is formed by the convergence of the ''North Paluxy River'' and the ''South Paluxy River'' near Bluff Dale, Texas in Erath County, Texas, Erath County and flows a distance of before joining the Brazos just to the east of Glen Rose, Texas in south central Somervell County, Texas, Somervell County. It is best known for numerous dinosaur footprints found in its bed near Glen Rose Formation, Glen Rose at the Dinosaur Valley State Park. The Paluxy River became famous for controversy in the early 1930s when locals found dinosaur and supposed human footprints in the same rock layer in the Glen Rose Formation, which were widely publicized as evidence against the geological time scale and in favor of young-Earth creationism. However, these anachronism, anachronistic "human" footprints have been determined to be elongated dinosaur tracks, river scour marks, and h ...

Fossil Trackways In The United States
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good understanding of the pattern of diversification of life on Earth. In addition, the record can predict and fill gaps such as the discovery of ''Tiktaalik'' in the arctic of Canada. Paleontology includes the study of fossils: their age, method of formation, and evolutionary significance. Specimens are sometimes considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years to 4.1 billion years old. Early edition, published online before print. The ob ...

Texas Archive Of The Moving Image
The Texas Archive of the Moving Image (TAMI) is an independent 501(c)(3) organization founded in 2002 by film archivist and University of Texas at Austin professor Caroline Frick, PhD. TAMI's mission is to preserve, study, and exhibit Texas film heritage. The organization has three main projects: the TAMI Online Collection, the Texas Film Round-Up, and Teach Texas. Its offices are located in Austin, Texas. Online collection The Texas Archive of the Moving Image website is a streaming video website that includes a variety of Texas-related films such as home movies, industrial films, local television, and orphan film materials as well as TAMI-curated online exhibits. The TAMI website was launched in 2008 using Glifos Social Media and the MediaWiki platform. The oldest films in the archive are a collection of Edison Studios films from the 1900 Galveston Hurricane. The TAMI site includes several curated collections with topics that include President Lyndon B. Johnson and his famil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedimentary Structures
Sedimentary structures include all kinds of features in sediments and sedimentary rocks, formed at the time of deposition. Sediments and sedimentary rocks are characterized by bedding, which occurs when layers of sediment, with different particle sizes are deposited on top of each other. These beds range from millimeters to centimeters thick and can even go to meters or multiple meters thick. Sedimentary structures such as cross-bedding, graded bedding, and ripple marks are utilized in stratigraphic studies. They help indicate the original position of strata in geologically complex terrains. They also provide insight into the depositional environment of the sediment. Flow structures There are two kinds of flow structures: bidirectional (multiple directions, back-and-forth) and unidirectional. Flow regimes in single-direction (typically fluvial) flow, which at varying speeds and velocities produce different structures, are called bedforms. In the ''lower flow regime'', ...

Trace Fossil
A trace fossil, also called an ichnofossil (; ), is a fossil record of biological activity by lifeforms, but not the preserved remains of the organism itself. Trace fossils contrast with body fossils, which are the fossilized remains of parts of organisms' bodies, usually altered by later chemical activity or by mineralization. The study of such trace fossils is ichnology - the work of ichnologists. Trace fossils may consist of physical impressions made on or in the substrate by an organism. For example, burrows, borings ( bioerosion), urolites (erosion caused by evacuation of liquid wastes), footprints, feeding marks, and root cavities may all be trace fossils. The term in its broadest sense also includes the remains of other organic material produced by an organism; for example coprolites (fossilized droppings) or chemical markers (sedimentological structures produced by biological means; for example, the formation of stromatolites). However, most sedimentary struct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleontology
Paleontology, also spelled as palaeontology or palæontology, is the scientific study of the life of the past, mainly but not exclusively through the study of fossils. Paleontologists use fossils as a means to classify organisms, measure geologic time, and assess the interactions between prehistoric organisms and their natural environment. While paleontological observations are known from at least the 6th century BC, the foundation of paleontology as a science dates back to the work of Georges Cuvier in 1796. Cuvier demonstrated evidence for the concept of extinction and how life of the past was not necessarily the same as that of the present. The field developed rapidly over the course of the following decades, and the French word ''paléontologie'' was introduced for the study in 1822, which was derived from the Ancient Greek word for "ancient" and words describing relatedness and a field of study. Further advances in the field accompanied the work of Charles Darwin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology
Geology (). is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology. It is integrated with Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface and the processes that have shaped that structure. Geologists study the mineralogical composition of rocks in order to get insight into their history of formation. Geology determines the relative ages of rocks found at a given location; geochemistry (a branch of geology) determines their absolute ages. By combining various petrological, crystallographic, and paleontological tools, geologists are able to chronicle the geological history of the Earth as a whole. One aspect is to demonstrate the age of the Earth. Geology provides evidence for plate tectonics, the ev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
