Is the Portrayal of the Dinosaurs in the Movie and Book Accurate in Real Life

A dinosaur has an antorbital fenestra with an open hole hip socket. The definition differs from the term used informally because it helped understand how the dinosaur moved and how they were categorized as species. There are four general characteristics that dinosaurs have as a result of their synapomorphies which are permeated acetabulum, ball-shaped head on proximal femur, the Cnemial crest on the proximial tibia, and an ascending process on astragalus. These four dinosaur synapomorphies are related to vertical limb support.

“Sex, Drugs, Disasters, and the Extinction of Dinosaurs” is written by Stephen Jay Gould, professor of geology and zoology at Harvard. This essay is one of more than a hundred articles on evolution, zoology, and paleontology published by Gould in national magazines and journals. It tells about scientific proposals for the extinction of dinosaurs – a confusing but an exciting problem that humanity tries to solve. By analyzing and describing each of the claims for the reptiles’ demise – sex, drugs, and disasters – Gould differentiates bad science from good science and explains what makes some theories silly speculations, while the other, a testable hypothesis.

Carnotaurus could kill a small dinosaur and it could kill or hunt down a bigger dinosaur. It had a fast bite but not a very strong bite. Carnotaurus could eat a

3 years later in 1903, paleontologist Elmer S. Riggs named the fossil remains. A few years later in 1909, there was yet another discovery of a Brachiosaurus by Werner Janensch in Tanzania (“Brachiosaurus,” 1996). Today after years of excavations of fossils and bones of dinosaurs, the Brachiosaurus is widely considered to be one of the largest dinosaurs due to its height of 40 feet, weight of 80 tons, and length of 80 feet. However in comparison to the mere size of the Brachiosaurus, its feet were small and narrow and its hind legs were short. In addition, its jaw was strong and contained large teeth. As well as having small narrow feet and short hind legs, the Brachiosaurus' snout was flat with large nostrils located at the top of its head. However, the use of the Brachiosaurus' nostrils still remains a mystery and lots of speculation still surrounds it to this day (“Brachiosaurus,”

Dinosaurs ruled the earth for over 65 million years and thankfully for the human race, they became extinct. Ultimately, only a major catastrophe could completely wipe out an entire species, let alone an entity of dinosaurs and the debacle on the causes of dinosaur extinction have flooded the minds of paleontologists for centuries. Geologist and zoologist Stephen Jay Gould published “Sex, Drugs, Disasters, and the Extinction of Dinosaurs,” to compare scientific and speculative causes of dinosaur decimation. Personally, I found this passage very informational and enjoyed reading it. Gould provides three theories that capture the reader’s curiosity, allowing room for pondering in one’s mind.

Which dinosaur was responsible for the death of the construction worker early in the novel? How is this dinosaur adapted for hunting?

In the article, "Comparison of the pelves of Sts 14 and AL 288-1: implications for birth and sexual dimorphism in australopithecines" by Martin Hausler & Peter Schmid discussed the difference between Sts 14 and AL 288-1 could either be sexual dimorphism or as species differences, or even both (Hausler 379). Sexual dimorphic is determined by the differences in birth canal dimensions as well as sexually dimorphic characteristics (Hausler 379). If AL 288-1 was a female, she would have had to give birth to a child with a neonatal brain size (Hausler 380). Delivery in AL 288-1 would have been more complicated than in modern humans (Hausler 380). Body size dimorphism would increase the average neonatal head size because cranial capacities are accessible for craniums of small sized individuals and neonatal brain size is dependent on the species mean as opposed to the species maternal brain volume (Hausler 380).

In site one, where the Parahomo fracticranius was discovered, it can be assumed that the habitat for the species was an open grassland due to the fact that other fossils of animals that lived in the area were grazers. Since there were 14 remains of both male and female sexes, it can be assumed that the P. fracticranius lived in a large multi-male, multi-female system. Based on the lectures from class, it is known that for most cases, multi-male, multi-female environments result in polypoly mating (Atkisson Lecture: Primate mating systems and primate evo). Therefore, it can be assumed that the P. fracticranius not only engaged in polypoly mating, but they also had some sexual dimorphism and large testes. The evidence that supports the sexual dimorphism claim can be seen when the body size of the female and male are compared since the male’s body size is 41 kg larger than the female’s.

While a theropod “beast-footed” carnivore includes the T. Rex, the ones that likely roamed Wrangel-St.Elias National Park were considerably smaller. The researchers found evidence of a single theropod that was likely a tiny 9 cm long and 7 cm wide due to an impression of the sinusoidal shape. Several ornithopod, medium and large plant-eating dinosaurs, was identified by blunt and rounded digit impressions which are usually 22 cm long and 26 wide. It was the first evidence that dinosaurs roamed this vast region.

Michael Crichton’s novel “Jurassic Park,” is a science fiction story about bringing dinosaurs back to life through genetic cloning. Throughout the book there are several references that dinosaurs are actually birds, not reptiles. Crichton did his research when writing these books because the science behind everything is correct. Dr. Henry Wu, the chief geneticist, cloned the DNA from insects in amber, a hard yellow resin of dried tree sap.

According to Holmes, the Time of the Giants begins by looking at the geological and its ecological conditions which creates opportunities for the expansion of dinosaurs in the Middle and Late Jurrasic Epochs. It describes widespread changes to ocean and land enviroments, including worldwide climate changes that served as catalysts for the spread of the jurassic “giants”: the dinosaurs. The book explores the broad ranges of the largest and biggest of all land animalsand tells the discoveries and changing scientific images of the early so-called “giants” over the past one hundred fifty years. By the end of the Jurassic Period, several evolutionary trends were in motion that would be played out by the giant creatures, dinosaurs, in the next

The word dinosaur was invented in 1842 by Richard Owen. Dinosaur comes from the Greek word “deinos” and “sauros” which translates to fearfully great lizard (“Learn about Dinosaurs”). Dinosaurs are always named in Greek and usually named after their unique fossils, where they 're found, it’s size or a person. Before a dinosaur can be officially named it must be approved by the International Commission on Zoological Nomenclature. It’s difficult to figure out how dinosaurs sounded, mated, behaved, what color/pattern they were and which ones are male or female. Paleontologists have however been able to discover that dinosaurs hatch from eggs, their bones have growth rings which can help figure out their age and that the larger dinosaurs lived for roughly 100 years and smaller ones for less. All dinosaurs evolved from other reptiles during the Triassic period. Dinosaurs are either herbivores or carnivores and are divided into two major groups. Bird hipped, Ornithischian, or lizard hipped, Saurischa. In the Saurischa hipped dinosaurs the pubis bone is down and to the front but in Ornithischian hipped it is point down and towards the tail (“Zoom Dinosaur”). The next step was to examine how dinosaurs behaved and their characteristics.

Jurassic Park by Michael Crichton demonstrated many dinosaur characteristics and behaviors. The dinosaurs were fictionally characterized to appeal to the readers. By examining the dinosaur’s appearance and behaviors of dinosaurs such as the duckbilled dinosaur, velociraptor, hypsilophodontids, dilophosaurs, Triceratops, apatosaurs, Tyrannosaurus rex, stegosaurs, and maiasaurs distinguished whether the evidence existed in the field of paleontology. The behaviors and characteristics of the dinosaur are divided into three factors as behaviors that were supported, not supported, and no evidence to support or refute the behavior.

The author is Michael Crichton, and the book is The Lost World. Many people have read this book, along with its predecessor, Jurassic Park, and many people have been enthralled with the thought of living dinosaurs in the 20th century. “What if the dinosaurs did not become extinct? What if they still exist?” (The Lost World takes off a couple years after the first book. A separate island is discovered, an island where the dinosaurs were actually created. There are two different research groups sent to the island. One to observe the dinosaurs in the wild and the other to bring them back for research purposes. The fighting starts from there. What many people don’t know, is that these books, along with countless other
