Some dinosaurs were carnivorous, while others were herbivorous creatures, such as the Ceratosaurus, a dinosaur that lived in the Late Cretaceous period, and most importantly in North America.
1. The appearance characteristics of the Ceratosaurus.
In terms of appearance, it is very similar to Triceratops, it is a dinosaur belonging to the ceratosauridae, after the study of the fossils, it will be found that there will still be a large hole in the head shield, which is relatively small in size, but it has a shield on the neck, but it is not safe enough, and it is hollow.
Therefore, experts believe that the existence of this shield is important to be able to coerce the enemy, perhaps as a courtship. Ceratosaurus can also have a long fan blade, the surrounding bone structure is still relatively long, and this dinosaur is a distant relative to the Pentaceratop, there are two protruding triangles.
2. Eating habits of Ceratosaurus.
Ceratosaurus is a kind of dinosaur that can eat grass, its face and mouth are very long, so it is speculated that Ceratosaurus can have a lot of choices at the moment of eating plants, and will continue to eat discontinuously, so in terms of survival habits, just like a cow, it can eat items all day long, as long as this way, it can obtain enough energy to meet the relevant needs in the future, so this dinosaur can have different eating characteristics.
Ceratosaurus itself belongs to a kind of individual survival, assuming that once it is attacked by some large dinosaurs, then the adult ceratosaurus will indirectly form a circle, but in front of these large dinosaurs, so in this situation, such a powerful dinosaur as Tyrannosaurus rex will not suddenly attack, so that Ceratosaurus can have weak offensive ability in the Cretaceous time.
Some dinosaurs were carnivorous, while others were herbivorous animals, such as Ceratosaurus, a dinosaur that lived in the Late Cretaceous period, mainly in North America.
1. Morphological characteristics of Ceratosaurus.
In terms of appearance, it is very similar to Triceratops, it is a dinosaur belonging to the ceratosauridae, through the study of its fossils, it will be found that there will still be a large hole in the head shield, which is relatively small in size, but it has a shield on the neck, but it is not hard enough, it is hollow.
Therefore, experts believe that the existence of this shield is mainly to be able to threaten the enemy, or to use it as a courtship. Ceratosaurus can also have a long fan blade, the surrounding bone structure is still relatively long, and this dinosaur is a close relative with Pentaceratop, there are two protruding triangles.
2. Eating habits of Ceratosaurus.
Ceratosaurus is a kind of dinosaur that can eat grass, its face and mouth are very long, so it is speculated that Ceratosaurus can have a lot of choices when eating plants, and it will continue to eat uninterruptedly, so in terms of living habits, it is like a cow, it can eat all day long, only in this way, can you get enough energy to meet the current related needs, so this dinosaur can have different eating characteristics.
Ceratosaurus itself belongs to a kind of group life, if once it is attacked by some large dinosaurs, then the adult ceratosaurus will directly surround a circle, and then face these large dinosaurs, so in this case, such a ferocious dinosaur like Tyrannosaurus rex, and will not attack suddenly, so that Ceratosaurus can have a strong defense ability in the Cretaceous period.
Ceratosaurus, Pentaceratop, Bison, Halberd, Ceratosaurus, Pachynose, Protoceratosaurus, Psittacosaurus, etc.
Ceratosaurus. Triceratops was a medium-sized, four-legged dinosaur with a very large shield on its head, as well as three horns, similar to a rhinoceros.
Whereas Ceratosaurus was similar in appearance to Triceratops and also had shields.
Triceratops was the latest dinosaur to appear and is often used as a representative fossil of the Late Cretaceous.
There are currently two species of effect: Triceratops and Triceratops.
Poplar Horned dinosaur is a kind of ceratosaurus in the Ceratosaurus subfamily Dinosaurus, born at the end of the Cretaceous period 68 million years ago, its appearance is very similar to Triceratops, but its neck shield is square, it is likely to be a direct relative of Triceratops, the body length can generally reach about 9 meters, the first fossils were found in North America.
Poplar Horned dinosaur is a large ceratosaur dinosaur with an average body length of 9 meters, which means that its body length is almost equivalent to the total length of two Asian elephants, and this size can be ranked 234th among the more than 770 dinosaurs that have been discovered so far, similar to the size of large dinosaurs such as Pingyongchuansaurus, Sadomatosaurus and Junglesaurus.
Poplar Ceratosaurus and Triceratops are very similar, and some scientists have even thought that they have different names for each other, because both have a very slender pair of frontal horns, extending upwards and outwards, and there is also a small bony protrusion on the nasal bone, and the cheekbones are also spiked, but the only difference is that their neck shield is very square, neither the rounded fan shape of a triceratops, nor the heart shape of a Utahatoceratosaurus.
Like most ceratosaurs, Poplar Ceratosaurus fed on ferns, cycads and conifers because of its very low height and parrot beak-like beak, and the fact that flowering plants did not grow widely during the Cretaceous period, while hard and resilient plants such as ferns were the dominant plants at the time, so scientists speculate that it probably fed on them.
The earliest fossils of Poplar Horned Dragon were found in North America, and this batch of fossils was buried in the Poplar Mountain Formation in New Mexico, USA, so it was named Poplar Horned Dragon, and in 2011, many Triceratops fossils were also found to have a square neck shield, so Thomas Holtz believed that Poplar Hornatosaurus was likely to be a synonym of Archaeopteratops or its ancestral relative.
Halberd. Also known as Ceratosaurus, it is a genus of herbivorous ceratosaurus dinosaurs, which lived in the Cretaceous period between about 76.5 million and 75 million years ago, and lived mainly in Alberta, Canada and Montana, USA. The skull is very large, with a horn of 50 centimeters on the nose of the prototype specimen and 4 to 6 sharp horns on the head shield, the number of which varies depending on the species. The head shield has several longest horns, each almost as long as the horn of the nose, about 50 to 55 centimeters long.
Restoration image) The Raptor was a feathered, bird-like carnivorous near-bird dinosaur.
Its type specimen is the only fossil, discovered in 1992 in Provence, southern France, and only a few bones have been found.
Fossilized teeth, claws, arms, and vertebrae have been found.
The dinosaur was the first raptor to be discovered in Europe, and like the rest of his family, the raptor had razor-sharp teeth and claws, and may have hunted in groups or by eating carrion, much like the modern vulture.
The skeletal structure of the raptor is very close to that of several raptors and dwarfs found in China during the early Cretaceous period.
It lived in Europe in the late Cretaceous period and was probably the last dinosaur on Earth.
Its name means "thief of fire", and this dinosaur was about nine feet long and weighed 7 kilograms.
In addition to its sharp teeth and powerful jaws, the fire raptor had huge claws on its second toe, which were enough to kill its enemies.
This particular dinosaur is often featured in old documentaries.
Stegosaurus (Late Jurassic Herbivorous Quadruped Dinosaur) Stegosaurus was a giant dinosaur, a herbivorous animal that lived in the late Jurassic and early Cretaceous periods, with a row of huge bony plates on its back, and a dangerous tail with four spikes to defend against predators, about 12 meters long and 7 meters high, and weighing 4 tons.
It is believed that they inhabit the plains and live in a group nomadic manner with other herbivores (e.g., S. sylvestris).
The original Stegosaurus has been discovered, and the remains of the ancestors of the Stegosaurus are still very few, so the origin of the Stegosaurus is currently unknown.
In the lower layer of the Morrison Formation, there are some fossils belonging to the Stegosauridae, which are millions of years older than the Stegosaurus genus.
These remains, along with similar fossils of the genus Hesperosaurus, appear in the Dermolith Order.
The earliest fossils of the Stegosauridae family are Lexovisaurus, which occur in the Oxford Clay Formation in England and France in the early to middle Callovian order.
The earlier and more primitive genus Huayangosaurus, the only genus in the family Huayangosaurus, appeared in China in the middle Jurassic period about 165 million years ago, about 20 million years before the genus Stegosaurus.
Earlier, there was the early Jurassic scelidosaurus, about 190 million years ago, a dinosaur with the characteristics of both ankylosaurs and stegosaurus.
The German genus Stegosaurus is a small tetrapod dinosaur with 17 plates and 4 soils; The scutellosaurus discovered in Arizona, USA, is much older and has non-absolute bipedal mobility.
These smaller, lighter armored dinosaurs were closely related to both stegosaurs and ankylosaurs.
In France, there is a possible footprint of an early armored dinosaur, dating from about 195 million years ago.
Ceratosaurus is very similar in appearance to Triceratops, but it is smaller, but it has a more exaggerated and ornate neck shield than Triceratops, but its shield is hollow, so scientists believe that its shield is not strong enough, and should be used to intimidate enemies or for courtship such as the peacock's tail.
Ceratosaurus is a ceratosaurus with a very long folded leaf structure.
The weight can reach 2 tons, about 4It was 8 meters long, about half the size of a triceratops.
However, the bony structure of the folds surrounding the neck was longer than that of Triceratops.
It also has a round nodulous protrusion five centimeters in diameter that is distributed on the back.
It is related to Pentaceratop, another species of ceratosaurus with elongated folds, with three horn-like protrusions and two seemingly horn-like buccal protrusions.
The skeleton of Ceratosaurus burnerii, located in the Royal Ontario Museum, is divided into two subfamilies: the subfamily Ceratosaurus with a short head shield (e.g., Ceratosaurus) and the Ceratosaurus subfamily (e.g., Ceratosaurus with a long head shield).
In addition to the larger and longer head shields, the face and mouth of the subfamily Ceratosaurus are usually long, and some paleontologists have pointed out that they can have greater plant options when feeding.
The long-headed shield is a feature that appeared at a later stage of dinosaur evolution, but the age of the Ceratosaurus was 76 million years ago, 70 million years ago, in the Upper Cretaceous.
The head shield of the Ceratosaurus is described as heart-shaped, as its head shield structure** contains two large holes and resembles a "loop".
The skeleton of Ceratosaurus burnetii, located in the Royal Ontario Museum, has some small cervical shield rim bony protrusions on the head shield of some Ceratosaurus that extend from the edge of the head shield.
The color of the head shield may be very bright, used to attract attention or as a courtship.
However, due to its large and thin head shield (as it is mainly between bones), it is difficult to provide a defensive function.
It may be used to regulate body temperature.
When a group of Ceratosaurus hunts, such as a Tyrannosaurus attack, the male Ceratosaurus may form a ring and shield its head outward, forming a once terrifying formation.
Like many ceratosauridae, Ceratosaurus had three main horns, one at the tip of the nose and two at the forehead, but different fossil finds have produced different results.
One is named CKaiseni's Ceratosaurus, with a long frontal horn; And Auerosaurus burnerii (C. Blazeii).Belli) but only has a short forehead.
Although they were both initially thought to be different species, it is possible that it is the male with the long frontal horn and the female with the short frontal horn.
Imagery of Ceratosaurus Interestingly, paleontologists have found some fossilized Ceratosaurus**.
There are many bony nodules (intracutaneous osteogenesis) on this **, with 5-6 on each side.
However, there is no way to know more about this specimen, especially its color.
