Tyrannosaurus Rex was the dominant predator in the late Cretaceous period. The Tyrannosaurus Rex‚ or T-Rex for short‚ lived about 85 million to 65 million years ago. T-Rex often resided in moist‚ humid‚ semi-tropical areas‚ usually near rivers or forested swamps. T-Rex fossils have been found in North America and Mongolia. The T-Rex was a large‚ dangerous predator that walked on two powerful legs. It had tiny arms with two fingers each. Their feet resembled birds and were fully equipped with gargantuan

Dr. Curry-Roger’s talk was very interesting and had many different points throughout. The first interesting point mentioned was that dinosaurs are birds. Dr. Curry-Roger explained that both birds and dinosaurs had a lot in common. She stated that birds have feathers that are complex‚ a fused clavicle‚ short bony tails‚ bones that are filled with air sacs‚ efficient breathing‚ and a fast growth rate. When comparing fossils to birds‚ they had many of the same features. Some dinosaurs had feathers‚

Alaska’s first elasmosaur fossil excavated The fascination with dinosaurs Since much about the early phase of the world is still much unknown‚ or at least mysterious‚ many are drawn to that particular era. Who wouldn’t‚ what with the exotic sea creatures and land creatures that lived in those times and would eventually become extinct or evolve to the animals of today? There are thousands of museums across the world featuring exhibits of these ancient creatures. One of those exhibits is in the University

Charles D Walcott was on the top of his of his horse‚ itching to get a good look at some fossils. As he continued to travel‚ he heard a sharp crack. He looked down‚ thinking his horse’s leg broke‚ but then stared in awe at the perfectly preserved fossil. This is the legend of how Mr.Walcott discovered the Burgess Shale‚ the cluster of fossils that changed geology forever. The Burgess Shale is found in Yoho Park‚ British columbia. Back when they were formed‚ the area where they were found was called

Did you ever want to be paleontologist‚ now you can. Fossils are the oldest rocks on earth. They can be anything that was over 4‚000 years ago. Fossils are what tell us what come before humans a million years ago. Do you ever stop and think there might be a T. Rex under your house. Well fossils preserved remains of organisms. Fossils can be over 4‚000 or a million years old. Usual the preserves are of animals. Fossils arranged from the size of a mouse to a ten story building. This is how all those

12.1 The Fossil Record 1. Form in Several Ways (The following are some of the processes that make fossils.) a. Permineralization minerals carried by water are deposited around a hard structure (may replace the hard structure) The most common fossils result from this process. A1. Natural Casts form by water removing the bone/tissue‚ leaving an impression in sediment. Minerals fill in the mold‚ recreating the original shape of the organism A2. Trace fossils record activity of an organism. Ex

A. R. Professor Sandy ARCH131-01 The Hudson-Meng Bison Bonebed Site The bison bonebed at the Hudson-Meng site illustrates the importance of taphonomy. This is because taphonomy shows how things have become a part of the fossil record; how natural processes contribute to the formation of archaeological sites‚ which‚ in turn‚ helps define patterns that should be interpreted in human behavioral terms. The bones were confined to an area approximately 100 square meters‚ and

Of all the species that have existed on Earth 99 percent have gone extinct and even fewer make it into the fossil record and a very small fraction of those that fossilize are actually found even partially complete. Even if all of them did fossilize many would be too hard dig for many of them. And also it is highly unlikely that most would be found complete‚ due to the number of natural disasters and processes that have happened from the animal’s death to whenever it is discovered. Natural disasters

There have been so many things discussed throughout these couple of months‚ everything from fossils‚ to Neanderthals‚ to evolution. From the beginning of evolution‚ our very start‚ our closest relative a chimpanzee‚ and modern man. We have gone through this journey and I have witnessed what the past looked like and made me appreciate my present. There are some incredibly specific items that need to be present in order for fossils to be procured‚ and they are only found in water‚ caves‚ or volcanoes
