When the Permian mass extinction came, the desert range began to expand, the ecology of the ocean was destroyed, the undersea volcano eruption caused toxic gases to spread to the entire atmosphere, the meteorite fell to the emperor, it seems that the world is about to be judged by the god of fate, after the Permian, the first time to dominate the continent of the zygomatic arch animal extinction, announced the decline of the zygomatic arch (like mammalian reptiles), which is also an important milestone from the Paleozoic to the Mesozoic!
When mentioning the Mesozoic ? What comes to mind? Are dinosaurs all over the continent ? Or the giant crocodile that appears ?
Or are they the sea crawlers who rule the oceans?
Diplodocus
For me, whether it is land or sea, the most famous is the Cretaceous, the two largest crocodiles of the Mesozoic Era appeared here, the strongest Dragon ruled the oceans of Europe and North Africa, and the period of the movie CP Spinosaurus and Tyrannosaurus Rex, the strongest land overlord turned out to be the "Hell's Aquarium" (the strongest sea monster is of course from the Miocene), leaving aside the land, the ocean is almost the origin of all things, after the Cambrian explosion of life, the land has not moved the sea but it is extremely lively, The first vertebrates were vertebrates that evolved 375 million years ago by a fish called the Titalik fish, the ancestor of all vertebrates, and although some scientists deny that the ocean is the origin of terrestrial animals, under this quiet sea, there are even more terrifying monsters!
The strongest Shanglong "Emperor Kerou"
The most famous marine animals of the Mesozoic Era are ichthyosaurs, plesiosaurs and plesiosaurs, in the early Cretaceous Period, the sea crocodile has declined, leaving only the monarch Marchmo crocodile (North America) and the Andean Stark dragon (South America), the short-necked dragon suborder Boyacakurus (North Africa) and the Queensland Krozoosaurus (Europe), which is the first Cretaceous, everything seems to be in the palm of their hands, they are the true rulers of the ocean!
However, after the Apudi-Arbu stage, Cruosaurus became extinct and the ecological niche in the ocean was vacant. After that appeared the most famous shark of the Mesozoic Era, the chalky beetle shark!
Chalk thorn beetle shark to give everyone the impression is often not afraid of large dragons, large sharks that are extinct by the dragon, cognition is in the documentary and some short videos released by users, and even documentaries appear many times it and the sea climb larger than themselves to duel and prevail, then the reality of the chalk thorn shark in the end is not so powerful, we next understand it
Man's chalky beetle shark
Cretoxyrhina, also known as Cretoxyrhina, is one of the largest sharks in the Cretaceous and currently has four active species
Type species: Man's chalky shark
Coarse-toothed chalky beetle shark
Welag chalky beetle shark
Argesy chalky beetle shark
It is also a very fierce top predator, mainly active in the open ocean, in the documentary, the chalk shark attacks the dinosaurs on the shore, and even fights against the dragon, in fact, it is not as powerful as we think
But that will be the rise of the dragon superfamily, Platts neptune dragon is the first batch of dragons to dominate the shallow sea, up to 10 meters in length, weigh up to 4 tons, the length is dominant, but the weight, Man's chalk thorny beetle shark is heavier than Platts neptune dragon, plus the shark structure is more belligerent, stronger, so Platts neptune dragon will only fall into the downwind in the face of chalk thorny armor, but Man's chalky thorny beetle shark is in Europe, and Platts sea king dragon in North America, in addition to Man's will pass, basically unlikely to meet
Chalky stingray shark
Chalky behead shark because of the killing of sword shooters, plus it is an ocean species, so it may be similar to the gray mackerel shark structure, with oversized eye sockets, can reduce heat, cooling, plus it is a rat shark, will also be like a thermostatic animal or medium temperature blood, so its thickness can not be compared with the Peruvian great white shark, otherwise it can not have super fast speed, therefore, chalky shark is likely to be a natural enemy of swordfish, or there is a potential predator threat
Chalky stingray sharks kill pterosaurs
The chalky shark has killed pterosaurs, and the bite marks of large sharks are suspected to have been found on the fossil of a toothless pterosaur, which indicates that the chalk shark has a good ability to leap out of the water to hunt, but it does not rule out the possibility of collecting corpses, but the pterosaurs who are there like to cross the ocean at sea level, and the possibility of the chalk shark actively attacking is not ruled out
Chalk spiny beetle shark's feeding habit is indeed quite wide, and even have attacked prey larger than themselves, that shark is not as big as it, so chalky shark will be invincible, there is no large dragon, the sea-dwelling sea crocodile is not as big as it, chalk shark may also attack coastal dinosaurs, and even some large plesiosaurs, and plate-beaked dragons, in the documentary, chalky-beetled sharks show that they will chase plate-beaked dragons at high speed, and found a white chalk shark's teeth in the fins of a plate-beaked dragon, and there are traces of healing. This suggests that the chalky stingray shark let the "lean flesh" to the mouth take off
The killer may have been a chalky shark
Sure, the shell of the turtle is not so thick, it is not difficult to break the armor, but the chalk shark will not use the savage attack of the weasel shark, but it will continue to attack, repeatedly interrupt, or prey on small turtles, it may also do this when eating ammonite, but ammonite is much easier to deal with than turtles
The chalky-spined beetle shark may have inherited the ecological status of the flatfin ichthyosaur, but its strength and level exceeded that of the latter, so after the extinction of the large shanglong and the extinction of the ichthyosaur, the status of the chalky-spined beetle shark should be similar to that of the land sharktooth
Despite this, it still has not escaped the fate of extinction, the extinction of the chalk thorn beetle shark is not conclusive, but it has nothing to do with the rise of neptune dragon in Zhongkanpan, Baidu and other platforms have searched for data that is thought to be eaten by the dragon and extinct, in fact, there is no super fast swimming speed to feed on the species of the dragon, may be related to the change of ecological niche
Anyway, in the period of domination of the fish, sharks still do not give up the ecological niche of the top predators, but again and again hope to be hit by fate again and again, but this is the world of reptiles, but the aura of the porbey shark is about to usher in the dominance of the new generation after the end of the Cretaceous, showing unprecedented huge strength, when the whale thinks that it dominates the ocean, a huge figure rushes to them, and then the sea is completely stained red, disappearing, and the era of the porbey shark will come again!
