Horned crocodile
The horned crocodile (Desmatosuchus) appeared in North America during the Middle and Late Triassic periods and became extinct at the end of the Triassic Period. The length of the body is about 5 meters, and the head is large
The limbs are short, the tail is long, and the body
The horned carapace on the top belongs to a special class of Entubosaurus, whose horn-like shell needles protruding from the back of its shoulders are 45 cm long, and although they are close relatives of the ferocious phytoplanosaurs, the leaf-like teeth show that the horned crocodile is a plant-feeding reptile.
Prussian crocodile
Prussian crocodile: Diplodocus suborder Primorphosis suborder Primordial plesiosaur inlaid crocodile incarcerated alligator-shaped superorder True crocodile New crocodile Shrew superfamily Caimanidae subfamily, violent temperament, up to 15 meters long, body width 2.7 meters, skull length 1.5 meters, larger than the Mesozoic dinosaur. Their opponents are their own kind.
The Amazon basin of South America is the world's most famous crocodile-producing region, and blunt-snouted crocodiles and bottlenose crocodiles remain the dominant waters there. In 1986, a Canadian paleontologist found fragments of the jaw fossils and partial skull fossils of the "Brazilian Prussian crocodile[1]", which had been named nearly 100 years ago, probably the largest giant crocodile of the Cenozoic generation, the "Brazilian Alluvius Crocodile[1]". These fossils spell out the largest crocodile skull known to the Cenozoic: 1.5m long.
Based on the combined head-to-body ratio of 1:7-9 for alligators and alligators, the Brazilian Prussian crocodile is about 10.5-13.5 meters; if you refer to the extremely old bay crocodile, the Brazilian Prussian crocodile may be 11 meters. But the teeth of this crocodile are not aging at all, and it is obviously incorrect to refer to the old bay crocodile. Although not the longest of the Cenozoic crocodiles, the Brazilian Prussian skull is the largest and thickest, and weighs more than its competitors (similar to the giant fish-eating crocodile) of the "Cenozoic Largest Crocodile".
The Prussian crocodile is 15 meters tall and weighs up to 18 tons.
It is estimated that the Brazilian Alligator should also be able to continue to grow until 19,20 meters. Because, as reptiles age, their body length can increase almost indefinitely.
Crocodile members have a large nose, the proportion of the femur of the genus Crocodile to body length exceeds that of crocodile genus, so the genus is not necessarily weaker than the crocodile in terms of land mobility, and the largest femur length of the genus is 545mm, although this is not the size of the femur of the largest individual, but it is the largest of the fossil femurs of the solid crocodile and the crocodile that have been found.
Whether the Prussian crocodile can kill the Tyrannosaurus rex, it is obvious that the average Tyrannosaurus rex 10.7 meters is already 7.2-7.9 tons (corresponding to the 18 tons of the Prussian),
Devil Crocodile
In addition to the emperor crocodile of the Mesozoic Era, there are still some other terrifying giant crocodiles in this world. The Amazon basin of South America is one of the world's most famous crocodile-producing places, and blunt crocodiles and bottlenose crocodiles remain the dominant waters there. In 1986, a Canadian paleontologist found fragments of the jaw fossil and part of the skull fossil that was named nearly 100 years ago, probably the largest giant crocodile in the Cenozoic Western Hemisphere, the Brazilian Prussian crocodile. These fossils spell out the largest known skull in the Cenozoic caimanidae subfamily: the total length of the bone (snout tip - square bone ending) is 1.5 meters, and the width of the root of the largest tooth can reach 4 to 5 cm.
According to the crocodile's head-to-body ratio, paleontologists such as Aragor speculated that the Perussian crocodile could reach a length of 12 meters, a body width of 2.7 meters, and weighed 18 tons, which was 10 tons heavier than the largest and most ferocious carnivorous Tyrannosaurus rex, and was almost 15 times the weight of the largest reptile in South America before the appearance of the giant crocodile. According to some mandibular fragments, the largest crocodile is likely to have a bend of 15 meters, and its weight is almost comparable to that of the largest pure terrestrial spinosaurus.
The large and fairly complete "devil crocodile" was found, which filled a gap in the discovery of paleontological fossils and further understood the diversity of paleoecology. But while rejoicing, paleontologists still feel some confusion: together with the "devil crocodile", scientists have also found some fossils of crocodiles of the same era, one of which has a skull of only 8 centimeters long, and some paleontologists believe that different crocodiles may have eaten different foods at that time, or that they competed for different resources, so individuals appeared to be very different. But this explanation does not seem satisfactory.
The constant disclosure of information shows that paleontologists have found some giant crocodiles that are comparable to the size of the Brazilian Prussian crocodile in the Cenozoic strata, such as the Malay crocodile that lived in India about 30 million years ago and resembled the modern fish-based Malay crocodile, the thick-nosed crocodile and the 11-meter origator with a bend of up to 13 meters, as well as the Filter-feeding Type A Mo's crocodile in South America with the Prussian crocodile and the offshore giant crocodile with sharp teeth - the Hook-nosed crocodile. Some scholars believe that giant crocodiles have appeared many times in the history of biological evolution, and can adapt to many different ecological niches in many species, and are quite successful species
Alligator
The alligator is 12 feet long,
The berserker crocodile with its long beak and bone armor on its body may have resembled a crocodile in appearance and behavior today. Like crocodiles, it also lives in rivers and catches fish with its sharp teeth to eat. It may also prey on other reptiles. Lived in Europe in the late Triassic period. It belongs to the para-crocodile class.
Living in the Mesozoic Triassic and Jurassic periods of 195 million years ago, the alligator reached 12 feet in length and was vicious and greedy, making it the top predator in the lake at the time. Often lurking in streams and lakes, exposing only the nostrils to the water and preying on fish or other animals.
Post crocodile
The Post Crocodile is a giant primordial species native to Texas, Arizona, and New Mexico, named after the small town of Post, Texas. From the restoration map, the Post crocodile resembles a hybrid of a crocodile and a Tyrannosaurus rex. The Post crocodile was 6 meters long and had a tall, massive skull that appeared to be able to catch and kill most of the large animals of the time
Peat crocodile
Peat crocodile ( scientific name : Sphagesaurus ) is an extinct crocodile of the family Peat crocodile family , belonging to the crocodile-shaped superorder Noto crocodile family , which lived in Brazil during the late Cretaceous period.
Monte Alto crocodile
The genus Montealtosuchus ( ) is an extinct species of crocodile superorder , a terrestrial animal. The fossil was discovered in 2004 in the Adamantina Formation in the Bauru Basin of Brazil, dating from the Cretaceous Toulon to Santo order.
In 2007, the fossil was named Montealtosuchus arrudacamposi, belonging to the Perro family. The genus name is the city of Monte Alto, where the fossils were found.
In 2004, the fossil was found in monte alto, in the state of São Paulo, and the fossil is quite intact and well preserved. The skull of the Monte Alto crocodile helped establish an evolutionary relationship between this fossil and modern crocodiles. The Monte Alto crocodile is a small crocodile with a length of about 2 meters. They may be terrestrial predators
