The Triceratops (figure 1) was and herbivore that lived in the late Cretaceous period, which was around 125 million years ago. The Triceratops existed at least 66 million years ago. It was a Rhinoceros-like dinosaur that had a sturdy body structure. It had four legs, three horns, and big eyes. Triceratopses were very complex.
The Triceratops was discovered near Denver, Colorado, in 1889. It was discovered by a Paleontologist by the name of Othniel C. Marsh. The first fossil that was discovered was mistakenly identified as an extinct species of Buffalo. A Triceratops skull was discovered in 1888 by John Bell Hatcher. A majority of the fossils were found in North America. Most were found in northern United States, to the Southern parts of Canada. The fossils were in good condition and fairly intact when discovered in Denver.
The Triceratops’ scientific name is Triceratops, which means three-horned face. Othniel C. Marsh named the Triceratops. Othniel C. Marsh discovered many dinosaurs such as the Allosaurus, Apatosaurus, Diplodocus, Stegosaurus, etc. The Triceratops is apart of the Ceratopsidae family along with the Vegaceratops, Sinoceratops, and the Centrosaurus. It is classified by the horns on its head.
The Triceratops was living in the late Cretaceous Era. It lived about 68 to 65 million years ago. The Triceratops were said to live in the Wyoming, Colorado, and Canadian area, where they have cold winters. The Tyrannosaurs dominated all of their prey in North America at that time. Also giant penguin-like marine animals called Polycotylid Plesiosaurs appeared in the oceans towards the south. The Earth was still dominated by dinosaurs at that time. During the late Cretaceous Era, North America was slowly moving westwards, whic...

An interesting rumor is that the Triceratops might have never existed. Studies show that as Triceratops’ get older their frills smoothen and their horns get sharper. As they age they start to look like a totally different dinosaur called the Torosaurus (figure 2). Paleontologist found plenty of older Torosaurus fossils but never any of younger Torosaurus’. Can the Triceratops be a younger Torosaurus? Nobody knows the answer to that infamous question.
The Triceratops were very interesting dinosaurs. They were very smart and strategic. They moved in herds and used mating calls. They were very complex. They had an interesting body shape that gave them an advantage towards their predators. They were known for their horns and parrot-like beaks. They were herbivores that lived in North America. Triceratopses were very interesting.
Around 144 million years ago, began the emergence of the Ornithischian dinosaurs during the cretaceous period and diversified into North America and Asia.
Saber Tooth Cats lived during the Ice Age, around 10,000 years ago, existing for about 42 million years, from the Eocene Epoch to the end of the Pleistocene Epoch. They roamed the earth during the early to late Pleistocene era (1.6 to 10,000 years ago) along with other animals such as mammoths and mastodons, however fossils of other
Raymond Rogers, David Krause, and Kristina Curry Rogers found significant evidence that the carnivorous dinosaur, Majungatholus atopus, was also a cannibal (Krause et al 2003). The dinosaur remains of the Majungatholus atopus were dated in the late Cretaceous Period from 65 to 70 million years ago. The Majungatholus atopus inhabited the plains of the northwestern Madagascar and bones and teeth continue to be found throughout the Maevarno Formation and within the channel-belt deposits of the Anembalemba Member. The Majungatholus is commonly found, along with other vertebra taxa in ‘bonebeds’ in the Madagascar area, which is probably the reason this dinosaur is still preserved. The trio discovered teeth marks in many bones of the ribs, ilium, and precaudal axial skeleton co...
Majungatholus atopus roamed the plains of northwestern Madagascar about 70 million years ago during the Late Cretaceous (Perkins, 2003; Rogers et al, 2003). The discovery of 21 tooth-marked elements originating from two Majungatholus atopus individuals suggests evidence that the dinosaur supplemented its diet by feeding on its own dead or hunting them (Rogers et al, 2003). It cannot be confirmed whether they were purely scavengers, hunters, or both. Scientists are certain that the marks are not the doing of any other predator because the teeth marks are not consistent with any other known species that lived in the area. Only one other theropod that inhabited the area during the time Majungatholus atopus did, Masiakasaurus knopfleri, had teeth and bite marks too small to have caused these markings. Two large crocodile species also shared the same ecosystem but their teeth were “too blunt and too irregularly spaced to have produced the narrow grooves found on the Majungatholus bones”(Perkins, 2003). The tooth marks on at least nine Majungatholus elements attest to intertooth spacing in the perpetrators jaw and denticle drag patterns consistent enough to make a compelling case for Majungatholus feeding on other Majungatholus (Rogers et al, 2003).
The Thescelosaurus was a “bird-hipped” dinosaur or an ornithischian ( Russell 2). This herbivore lived near the end of the Cretaceous period, about one million years before the conclusion of the dinosaur era. Thescelosaurus was about the size of a short-legged pony, according to paleontologist Dr. Dale Russell and was native to North America from Wyoming up to Alberta, Canada.
The Minoan Snake Goddess was first discoverd in 1903 by british archaeologist named Arthur Evans.

Deinos, Greek for fearfully great; awe-inspiring and sauros meaning a lizard. From these words “Dinosaur” is created. When imagining a dinosaur, do thoughts of a large Tyrannosaurus Rex, a swift Velociraptor, or a gliding Pterodactyl appear? Or are those thoughts composed of an image of a small Compsognathus? Do visions of the dinosaurs that we often saw in our childhood come to mind? The amiable brightly colored friends in cartoons or the fearsome bloodthirsty experiments in movies? Were those dinosaurs portrayed accurately? There are features such as size that was changed to appeal more to popular media and for creativity. The Dilophosaurus is a dinosaur that became popular in the the public due to Michael Crichton’s novel “Jurassic Park”. Dilophosaurus means “Two crested lizard”. It was named this because of the two crests on it’s head.The Dilophosaurus in Jurassic Park, both in the movie and book, has a false depiction of size, abilities that no one can prove, and features which are unlikely.
They ruled the world before the time of the dinosaurs, from the Cambrian Period to the
Until recently, scientists believed the chances of finding a fossilized dinosaur heart were extremely slim. The heart belonged to a 66 million year old dinosaur found in Harding County in Northwestern South Dakota. The dinosaur, found in 1993, weighed over 650 pounds and was 13 feet long. The dinosaur was in fairly good condition with the exception of the left side of the skeleton. The small, plant-eating Thescelosaurus, nicknamed ‘Willo’ has been acquired by the North Carolina Museum of Natural Sciences. Thescelosaurus was an ornithischian, or "bird-hipped," dinosaur that lived in the latter stage of the Cretaceous period. This was approximately 1 million years before the end of the dinosaur era. Native to North America, its range extended from the northern United States up into Canada. Since using the 3-D software to reveal Willo's heart, scientists have also used it to create 3-D images of the fossil's skull, and of remains from other dinosaurs in the museum's collection.

The cheetah is known as a very interesting animal for many reasons. One of the prime examples of why so many people believe the cheetah is such an amazing animal is because of the speed it contains. For example, the cheetah can accelerate to speeds of over sixty miles per hour in a matter of three seconds, which is in fact, faster than some cars.(Cheetah facts, about cheetahs 1). Believe it or not, sixty miles per hour isn’t the fastest a cheetah can run! The fastest recorded time for a cheetah’s running speed was seventy five miles per hour while using their tails to steer. (Murray 1) (One Kind, Cheetahs 1). For example, cheetahs can turn in midair when they’re at a full sprint, which is pretty amazing. (One Kind, Cheetahs 1). Another reason the cheetah is such an incredible animal to observe is their hunting ability. Cheetahs are often predators in the wild, which means they hunt other
In the 1800’s, paleontologists discovered a small, bird-like creature about the size of a modern-day jay. It had the long, bony tail and a mouth full of sharp teeth like a dinosaur, but it had the beak, feathers, and wings of a bird. It was one of the only maniraptoran theropods of its time- about 150 million years ago in the late Jurassic period, an early period of dinosaurs. Also, many scientists believe that the early lizard would have been able to glide from tree to tree, looking down at the forest floor in search of prey like the birds at the
Reptiles are vertebrate, or backboned animals constituting the class Reptilia and are characterized by a combination of features, none of which alone could separate all reptiles from all other animals.The characteristics of reptiles are numerous, therefore can not be explained in great detail in this report. In no special order, the characteristics of reptiles are: cold-bloodedness; the presence of lungs; direct development, without larval forms as in amphibians; a dry skin with scales but not feathers or hair; an amniote egg; internal fertilization; a three or four-chambered heart; two aortic arches (blood vessels) carrying blood from the heart to the body, unlike mammals and birds that only have one; a metanephric kidney; twelve pairs of cranial nerves; and skeletal features such as limbs with usually five clawed fingers or toes, at least two spinal bones associated with the pelvis, a single ball-and-socket connection at the head-neck joint instead of two, as in advanced amphibians and mammals, and an incomplete or complete partition along the roof of the mouth, separating the food and air passageways so that breathing can continue while food is being chewed. These and other traditional defining characteristics of reptiles have been subjected to considerable modification in recent times. The extinct flying reptiles, called pterosaurs or pterodactyls, are now thought to have been warm-blooded and covered with hair. Also, the dinosaurs are also now considered by many authorities to have been warm-blooded. The earliest known bird, archaeopteryx, is now regarded by many to have been a small dinosaur, despite its covering of feathers The extinct ancestors of the mammals, the therapsids, or mammallike reptiles, are also believed to have been warm-blooded and haired.
