triceratops
The Triceratops is a quadrupedal herbivore that lived during the late Cretaceous period—or about 68 million years ago. This dinosaur was first discovered near Denver, Colorado in 1887. When it was first discovered it was believed to have been an unusual type of bison. However, it was discovered rather quickly that this wasn’t just an unusual form of bison but was actually a dinosaur. Since then, Triceratops specimens have been found all over North America. The name of this dinosaur translates into “3 horned face” from the Greek “Tri” meaning three and the word “keratops” meaning face.
It is believed that Triceratops ate mostly low growth vegetation such as ferns and shrubbery. Scientists believe that their large volume of teeth suggested that they ate large volumes of fibrous plant material each day and that these large batteries of teeth were needed to replace the ones that were damaged by wear and tear.
Currently, there are two theories which suggest what the horns of the Triceratops were used for. One theory says that this dinosaur’s horns were used to defend itself in combat against other dinosaurs—particularly the T- Rex—which is known to have been the mortal enemy of this animal. The second theory suggests that this animal’s horns served a very limited purpose in combat and was instead used during courtship rituals.
Although the word Triceratops means 3 horned face, this dinosaur actually only had 2 proper horns. The third horn was made out of soft proteins and wasn’t a proper horn. In fact, scientists aren’t really sure what the purpose of this false horn is. Another interesting fact about triceratops is that almost one third of the length of the Triceratops was its skull. A typical Triceratops was approximately 26 feet long (or 8 meters), while its skull was approximately 7 feet long (or 2.33 meters long).
The Triceratops could weigh anywhere between 6 and 12 tons. Which is about the weight of a modern diesel truck. This dinosaur measured over 10 feet in height. That is as tall as a first story building. This dinosaur has approximately 400 to 800 teeth during the course of its lifetime. However, it didn’t use all of these teeth at one time. It was constantly replacing them throughout its lifetime as it wore them out.
Tyrannosaurus rex
Tyrannosaurus is a genus of coelurosaurian theropod dinosaur. The species Tyrannosaurus rex (rex meaning "king" in Latin), commonly abbreviated to T. rex, is a fixture in popular culture. It lived throughout what is now western North America, with a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formations dating to the Maastrichtian age of the upper Cretaceous Period, 67 to 65.5 million years ago. It was among the last non-avian dinosaurs to exist before the Cretaceous–Paleogene extinction event. Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to the large and powerful hindlimbs, Tyrannosaurus forelimbs were small, though unusually powerful for their size, and bore two clawed digits. Although other theropods rivaled or exceeded Tyrannosaurus rex in size, it was the largest known tyrannosaurid and one of the largest known land predators. By far the largest carnivore in its environment, Tyrannosaurus rex may have been an apex predator, preying upon hadrosaurs and ceratopsians, although some experts have suggested it was primarily a scavenger. The debate over Tyrannosaurus as apex predator or scavenger is among the longest running in paleontology. Tyrannosaurus rex was one of the largest land carnivores of all time; the largest complete specimen, FMNH PR2081 ("Sue"), measured 12.8 metres (42 ft) long, and was 4.0 metres (13.1 ft) tall at the hips. Mass estimates have varied widely over the years, from more than 7.2 metric tons (7.9 short tons), to less than 4.5 metric tons (5.0 short tons), with most modern estimates ranging between 5.4 and 6.8 metric tons (6.0 and 7.5 short tons). Packard et al. (2009) tested dinosaur mass estimation procedures on elephants and concluded that dinosaur estimations are flawed and produce over-estimations; thus, the weight of Tyrannosaurus could be much less than usually estimated. Other estimations have concluded that the largest known Tyrannosaurus specimens had a weight exceeding 9 tonnes.
