Triceratops Triceratops was a species of herbivorous dinosaur. Triceratops lived during the Mesozoic Era, during the days of the late Cretaceous period. A large herbivorous dinosaur, Triceratops grazed on plants and relied on its horns and frilled head for defense, cutting away at plants with its sharp beak. were larger relatives of the Chasmosaurus. They appear in Ice Age: Dawn of the Dinosaurs, The Triceratops are shown very briefly, wading through a pond.

Triassic The Triassic ( /traɪˈæsɪk/) is a geologic period and system which spans 50.9 million years from the end of the Permian Period 252.17 million years ago (Mya), to the beginning of the Jurassic Period 201.3 Mya. The Triassic is the first period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events.[8]

Jurassic Period A+ A-. Print Email. The Jurassic is a geologic period and system that extends from 201.3± 0.6 Ma (million years ago) to 145± 4 Ma; from the end of the Triassic to the beginning of the Cretaceous. The Jurassic constitutes the middle period of the Mesozoic Era, also known as the Age of Reptiles.wo other extinction events occurred during the period: the Late Piensbachian/Early Toarcian event in the Early Jurassic, and the Late Tithonian event at the end; however, neither event ranks among the 'Big Five' mass extinctions.

triceratops (trī-sěr'ə-tŏps') A large herbivorous dinosaur of the genus Triceratops of the late Cretaceous Period, measuring up to 7.6 m (25 ft) in length. Triceratops had a squat, tanklike body, a beaklike mouth with a short horn over it, and a long horn over each eye. The back of its neck was covered with a wide, bony plate.

Phanerozoic The Triassic ranges from 250 million to 200 million years ago. The Triassic is a desolate transitional state in Earth's history between the Permian Extinction and the lush Jurassic Period. It has three major epochs: the Early Triassic, the Middle Triassic and the Late Triassic.

<< <ContentsWorks Cited> >> In geology texts, the Mesozoic Era, which began some 250 million years ago (mya), is usually called the Age of Reptiles.. It is divided into three periods, the Triassic, Jurassic, and Cretaceous (see Table 9.1). In the typical description, encountered in texts on geology, paleontology, and evolutionary biology, it is the era during which reptiles dominated life on earth until their extinction at the end of the Cretaceous Period, 65 million years ago..

Cretaceous Period The Cretaceous period marks the end of the age of Dinosaurs with what is known as the Great Extinction. However, this period gives us some of the most beloved dinosaurs of modern days, like the Triceratops and, of course, the Tyrannosaurus-rex, king of the dinosaurs.

Triceratops Triceratops is the best-known of the ceratopsids, though the genus's exact placement within the group has been a point of contention amongst paleontologists. Two species, T. horridus and T. prorsus, are considered valid, although many other species have been named.

About dinosaurs Dinosaurs lived between 230 and 65 million years ago, in a time known as the Mesozoic Era. This was many millions of years before the first modern humans, Homo sapiens, appeared. Scientists divide the Mesozoic Era into three periods: the Triassic, Jurassic and Cretaceous.

What is the difference between a trapezoid and a rhombus? The sides' length and number of pairs of parallel sides. See explanation. A trapezoid is a quadrilateral with at least one pair of parallel sides (called bases), while a rhombus must have two pairs of parallel sides (it is a special case of a parallelogram). The second difference is that the sides of a rhombus are all equal, while a trapezoid may have all 4 sides of a different length.

This period lasted about 53 million years and marked a dramatic burst of evolutionary changes in life on Earth, known as the Cambrian Explosion..

The Idiocy, Fabrications and Lies of Ancient Aliens The Idiocy, Fabrications and Lies of Ancient Aliens. The History Channel presents self-appointed challengers of science who take on the idea that aliens caused the extinction of non-avian dinosaurs. Despite what basic cable cranks might say, Tyrannosaurus and Triceratops were not driven to extinction by aliens. Until now, I have assiduously avoided Ancient Aliens. I had a feeling that if I watched the show—which popularizes far-fetched, evidence-free idiocy about how human history has been molded by extra-terrestrial visitors—my brain would jostle its way out of my skull and stalk the earth in search of a kinder host.

- The dinosaur known as Triceratops looked something like a modern rhinoceros. However, it had three sharp horns on its head. The name Triceratops means three-horned face.. Triceratops also had a bony neck frill that surrounded the head like a huge collar.

- The Mesozoic Era. The Mesozoic Era is divided into three time periods: the Triassic (251-199.6 million years ago), the Jurassic (199.6-145.5 million years ago), and the Cretaceous (145.5-65.5 million years ago).*.

Reptile Archosaurs developed into the well-known dinosaurs and pterosaurs, as well as the ancestors of crocodiles. Since reptiles, first rauisuchians and then dinosaurs, dominated the Mesozoic era, the interval is popularly known as the Age of Reptiles.

Dinosaurs roamed the planet for about 165 million years, during a time in the Earth’s history called the Mesozoic Era. It is difficult to imagine how long this was, until we compare it with ourselves: humans have lived on Earth for less than two million years. During the Mesozoic Era, the Earth’s landmasses changed dramatically, new seas were formed, and plants and animals evolved.

RelaxâTriceratops Really Did Exist All of this angst is unnecessary. As Scanella and Horner pointed out in their paper, and as multiple summaries of the study have stated, Triceratops (described in 1889) was named before Torosaurus (described in 1891). According to the rules by which scientists name organisms, this gives Triceratops priority, so the name  Triceratops.
