Arguments In The Possibility Of Dinosaurs In My Backyards

Explain why the author and his colleagues chose to focus on 375 million year old rocks in their search for fossils. Be sure to include the types of rocks and their location during their paleontology work in 2004.

The longbow has changed England’s history forever. Dating back to the 1300s the English used the longbow. In 1340 at the Battle of Sluys the English attacked packed French ships using the longbow and the French suffered tremendously. In 1346 after the Battle of Crecy the French had lost 11 princes, 1,200 knights, and 30,000 common soldiers, when the English only had lost 100 men. In the Battle of Poitiers in 1356, the longbow was used and killed about 2,000 mounted French knights of the elite French army.

The environment in the ancient sea, which contained crustaceans, molluscs, and echinoderms, helped the hypothesis that 112 million years ago the area was covered in shallow lagoons. Numerous Cretaceous dinosaur tracks have been found near Glen Rose, Texas. This is where horseshoe crabs were found in Paluxy River.

The Inoceramid clams found in the Niobrara formations leads to the assumption that the mudstone and limestone were deposited at the sea floor. Clams today are mostly found in the deep burrows of mud, and with the principle of uniformitarianism you can deduce that those clams were also most likely living on the sea floor. The clams living at the sea floor would be supported by the fact that the clam fossils were found in mudstone and limestone because mudstone is usually in lower energy environments like the sea

The Crato Formation lithologies were most likely deposited when there was a marine transgression; which is what the Cretaceous period is renowned for (Hu et al. 2012). The build-up of laminated limestones and different lithologies in the stratigraphic column could suggest that it was a lagoon depositional environment (Martill and Frey, 1998).

The author and his colleagues chose to focus on 375 million year old rocks in their search for fossils because amphibians that look dissimilar to fish were discovered in 365 million year old rocks, while fish without amphibian characteristics were discovered in 385 million year old rocks. Thus, it is possible that the evolutionary intermediary, or the “missing link” between fish and amphibians, would be discovered in 375 million year old rocks, between the two time periods. The rocks examined were sedimentary in composition, as the gradual and relatively gentle formation of sedimentary rock under conditions of mild pressure and low heat are conducive to the fossilization of animal remains. Sedimentary rock is also often formed in rivers and seas, where animals are likely to live. This site provides a resource that describes means by which fossils are formed and how the fossil record may be interpreted, and shows some examples of fossils demonstrating evolution through geological periods: http://www.fossilmuseum.net/fossilrecord.htm. In 2004, Shubin and his colleagues were looking for fossils on Ellesmere Island, in northern Canada. This location was chosen because of its lack of human development, as well as of obstructing natural formations and life forms such as trees, which

Sedition Act of 1918- on may 16,1918, the U.S congress passed the Sedition Act, a piece of legislation designed to protect America’s participation in World War 1.

Fossils of the seed fern Glossopteris are found across all of the south continents. These seeds are too heavy to be carried away across the ocean by wind. Mesosaurus fossils are found in South America and South Africa. Mesosaurus is a creature that could swim, but only in FRESH water. Cynognathus and Lystrosaurus were reptiles that lived on land. Both of these animals could not swim at all. Their fossilised parts have been found across South America, Africa, India and Antarctica.

Most Cambrian rocks contain fossils of trilobite shells, cap-shaped or flattened shells, and brachiopods (Whittington, 1985). When Walcott went looking for North American Cambrian fossils in August of 1909, he ended up in the Canadian Rocky Mountains. He and his wife found a loose block in the ridge they were searching near, split it open, and found what they later classified the “lace crab” (Briggs, 1994). Walcott knew right away what they had discovered was something different – the soft parts of the crab, such as the limbs, were preserved. During the next season, Walcott and his sons came back to the Shale, searching the slopes along the trail where they had discovered the loose block to find fossil layers. Luckily for them, the Shale rock layers were almost horizontal, and for thirty days a team quarried the ridge. The next year, they spent even longer quarrying. The last year spent quarrying the rocks was in 1917, when Walcott was 67 (Briggs, 1994). The rocks were removed from the ridge using picks, chisels, long iron bars, and small explosives. All the quarrying done by Walcott and his crew resulted in over sixty five thousand fossils, now stored in the

The reading passage states that paleontologists intentionally split a fossilized bone of a 70 million-year-old dinosaur, called T-Rex, and discovered several substances that might be the original tissue of the dinosaur, such as blood vessels, red blood cells, and collagen. However, the lecturer casts doubt on it and provides conclusive evidence to support his statement.

These techniques led to the discovery of the boundary between the two eras. A single thin layer of clay found within predominantly limestone rocks established this. By comparing the marine life found in, above, and below the clay, the marine life, like the dinosaurs, had been terribly affected by the extinction event. The percentage of life in the upper layers was dramatically lower than that in the lower. This was far more compelling than what was suggested by dinosaur’s fossils.

The article that I chose for this assignment is about the recent discovery/confirmation of the first known dinosaur which lived and thrived in the water. The Spinosaurus aegyptiacus was found and collected by Dr. Nizar Ibrahim from the University of Chicago. Ibrahim along with his colleague Dr. Paul Sereno determined that based on the fossil discovered that the specimen was a swimming dinosaur. Technically, the bones of Spinosaurs were first discovered 100 years ago by a German paleontologist in Egypt. However, these bones were only a sample of the full skeleton and they were stored in a museum in Munich, Germany which was later bombed by the Allies during World War II; thus

Evolutionary scientists say that dinosaurs died millions of years before man had evolved. But does the evidence support that? Could they not have lived alongside man, as so many ancient stories suggest? From the unfossilized T-Rex bone to the stories of encounters with dragons to Mokele-Mbembe in Africa are some of the pieces of evidence that support this view that goes along with the Creationist model of a Young Earth of approximately 6,000 years.

Capital punishment is the same as the death penalty. When a person commits such a cruel crime such as murder, their punishment may just be their life getting taken.

A fossil is the remains or trace of something that was once alive, but is now long-gone and dead. We know that dinosaurs existed because of their fossil remains, mostly bones and shells that we have found. The dinosaurs (except the birds) went extinct, probably due to the after-effects of an asteroid which hit the Earth 65 million years ago. Its impact caused huge fires, volcanic
