<h1 class="pgc-h-arrow-right" > how is one of the representatives of heavy "weapons" in the Cretaceous period defined? </h1>
Triceratops (genus name: Triceratops) As the last dinosaur to appear in the Cretaceous Period, Triceratops can be said to be very representative. As a genus of plant-eating dinosaurs of the ornithopod order Ceratopsae, the current fossil origin is still mainly in North America, which has been found in the Late Cretaceous Late Mastrik Formation in North America, with a history of 68 million to 65 million years.
People have constructed the image of Triceratops from the fossils of Triceratops. Triceratops ranked medium among all quadruped dinosaurs, ranging from 7 to 9 meters in length, 2.4 to 2.8 meters in height, and 5.5 to 10 tons in weight.
The most remarkable thing is that they have this huge head shield and three horns, which is not difficult to think of modern rhinoceros also has proud horns. The use of the head shield of the Triceratops and the three horns on the head shield is still full of controversy, and the traditional concept of the head structure of the Triceratops is like a combination of "spear" and "shield", the attack power and defense power are directly full, and it is generally interpreted as a weapon evolved to resist the predatory killing of carnivorous dinosaurs. But recent studies have given different interpretations of the use of Triceratops' head structures, suggesting that these structures may simply be a means for male Triceratops to attract the opposite sex, or to express their dominance, similar to the functions of some modern creatures such as reindeer, goats, elk, etc.
The most significant and important "weapons" of Triceratops are their horns and neck shields, their head shields can grow up to 1.5 meters (I think this length should be from the mouth of the Triceratops to the forehead distance), above the nostrils of the mouth and nose there are two eyes with one and a pair of large horns, the length of the three horns is more than 80 centimeters, and behind the skull is a shorter bony head shield, which looks like a small dagger.
The most important things that carry the "tank" at high speed are two things, a high-performance heart and a strong and durable thigh. We don't know about the heart of Triceratops, but we can learn about the legs of Triceratops and how the legs of Triceratops worked. Triceratops had short limbs and large soles , with five short toes on the front foot and four on the back foot. Although Triceratops is defined as a four-legged dinosaur, there is a wave of controversy over what kind of posture Triceratops usually maintains.
Under the common concept of the forelimbs of Triceratops, it is believed that the role should be to share the pressure brought by the head shield of the head to the neck, so it is extended from the chest to the sides, so the usual posture of the Triceratops should be based on the landing of the limbs. We can see this triceratops gesture in the works of some of the proponents of this claim (Charles R. Knight and Rudolph F. Zallinger). However, with the continuous discovery, excavation, and analysis of the foot fossils of horned dinosaurs, coupled with modern technology that can reshape the bones of dinosaurs to a certain extent, people can more intuitively observe the posture of dinosaurs, with this evidence, the new statement is more reasonable, Triceratops maintains an upright posture when walking normally, but the elbow is slightly bent, in the middle of the two theories of fully upright and fully extended (similar to modern rhinos). However, this conclusion does not rule out that Triceratops would take a fully extended posture when resisting or eating.
<h1 class="pgc-h-arrow-right" > where does Triceratops belong? Where does it go from here? </h1>
Triceratops is arguably one of the most famous dinosaurs in the family Triceratops, a group of medium-sized ceratopsid dinosaurs that lived on the North American continent. Over the years, where exactly should Triceratops exist in the order Ceratopsa? Scholars from all walks of life also have their own opinions on this issue, so why does a question of attribution be debated for so long?
This is also related to the confusion caused by Triceratops, which is mainly due to the short and hard head shield of Triceratops, which is similar to some dinosaurs in the subfamily Triceratops, but the long horns (two horns on the forehead) of Triceratops are not available to dinosaurs under the subfamily Triceratops, and such features are only preserved by dinosaurs under another type of "Triceratops" (or "Plesiosaurs"). Simply put, Triceratops has the characteristics of two types of dinosaurs, so it is difficult to judge the Triceratops' belonging for a while.
In the first study of the ceratops, Richard Swann Lull proposed two clades, one that developed towards Triceratops included Triceratops and Diplosaurus, and the other included Ceratopsa and Oxeratops, a hypothesis that Triceratops belonged to the subfamily Triceratops. Some later studies also supported this view in part, and formally divided the horned dinosaurs with short-headed shields into the subfamily Of Triceratops (among others), and the horned dinosaurs with a pair of long horns into the family Plesiosaurs.
Things will inevitably turn around at a certain time. In 1949, Charles Mortram Sternberg first questioned such a hypothesis. And based on the head characteristics of Triceratops, that is, the characteristics of the head and horns, it is believed that Triceratops should be closer to Plesiosaurus and Plesiosaurus, so that Triceratops should be placed in the subfamily Triceratops.
Later, in 1990 Lehman defined two subfamilys in 1990, based on several morphological features, and attributed Triceratops to the subfamily Ceratosaurus to support Sternberg's view. In fact, with the exception of the short-headed shield, Triceratops is quite in line with the characteristics of the subfamily Ceratopsae. Peter Dodson's 1990 study of the taxonomy of related branches and the 1993 morphological study reinforced the argument that Triceratopsae is classified as a subfamily of Ceratopsae.

Triceratops was a plantational eating dinosaur, but their usual power was indeed enormous. Triceratops has its own tricks about eating. Triceratops usually hit or nibble on trees with its head horns, beak-shaped mouth, and body, causing the trees to fall and lose their leaves. Because it was a herbivore , Triceratops had a long , narrow beak-like mouth at the front of its jaw , which was considered more suitable for grasping , pulling , rather than biting. The teeth of Triceratops are arranged in a tooth battery, with 3 to 5 columns of teeth on each side of the three lower sides, and each column of teeth has 35 to 40 teeth.
The number of teeth generally increases positively as the size of Triceratops increases, and can have teeth ranging from 436 to 800. Most of the teeth were fully utilized, and Triceratops would change teeth non-stop throughout its life, cutting and grinding food in a vertical manner. Most of the recipes of Triceratops are based on palm trees and some cycads, or some grassland ferns.
<h5 class= "pgc-h-arrow-right" > I like to ride a Triceratops in the game</h5>
I know very little about the image of the Triceratops in other images and musical works, but in the movie "Jurassic Park", there was a Triceratops who was sick because he could not adapt to modern vegetation. But I know a lot about the game, such as jurassic park: Chaos Island, a PC game released in 1997, or Ark: Survival Evolution, which I talked about in the Dodo issue before, all of which have triceratops.
