Prehistoric crocodiles are close relatives of the first dinosaurs, and gentleman Qi introduces them to everyone.
<h1>Genus Shield Crocodile
</h1>
Aegisuchus, ShieldCroc
Habitat: North Africa
Historical period: Middle Cretaceous (95-100 million years ago)
Dimensions and weight: about 50 feet long, 10 tons
Feeding habits: Fish and small dinosaurs
Features: Large, flat nose
In the middle of the Cretaceous Period, crocodiles in African watersheds, the earliest giant prehistoric "crocodile" series, were at least 50 feet long and 70 feet tall when adults
100 million years ago, the Sahara Desert in northern Africa was a verdant landscape with many dinosaurs, crocodiles, pterosaurs, and even small mammals. There are many aspects of the shield crocodile that we don't know about, but there's reason to infer that it's the classic "ambush predator."
<h1>Duck crocodile
Duck crocodile (Anatosuchus)
Habitat: Africa
Historical period: Cretaceous (115-120 million years ago)
Size: Approximately two feet long
Diet: Insects and crustaceans
Features: small size; Four-legged posture with a nose like a duck
Similar to duck-billed dragons. American paleontologist Paul Sereno describes duck crocodiles hunting from the soil with flexible noses
<h1>Genus Diplodocus</h1>
Genus Angistorhinus
Habitat: North America
Historical period: Triassic (220-230 million years ago)
Size and weight: about 20 feet long, half a ton
Diet: Small animals
Features: large size; The skull is long and narrow
It was narrated and named in 1914 by M. G. Mehl. The genus name means "long beak" or "hook-like beak", which refers to the narrow snout of the narrow-beaked dragon, or the hook-like end of the upper jaw.
<h1>Alaripo crocodile</h1>
Araripesuchus
Habitat: Africa and South America
Historical period: Cretaceous (950,000-1.1 million years ago)
Dimensions and Weight: Approximately six feet long and weighs 200 pounds
Diet: Meat
Features: Long legs and tail, short head
Judging by its muscular and streamlined body, Araripesuchus is one of the most dangerous species
<h1>Armadillo crocodile genus
Armadillosuchus
Habitat: South America
Historical period: Cretaceous (850,000-950,000 years ago)
Size and weight: About seven feet long and 250-300 pounds
Features: Moderate; Thick striped armor
The legs were longer than those of modern crocodiles, and the thick armor on the back resembled that of an armadillo. Outwardly, armadillos are classified as cousins of crocodiles. It may be an extrusion reptile, preying on small animals inside caves.
<h1>Polo crocodile genus
Genus Baluschus (Baurusuchus)
Habitat: Plains of South America
Dimensions and Weight: Approximately 12 feet long, 500 pounds
Features: Long legs, well-developed chin
Prehistoric crocodiles were not limited to river environments, in fact, these ancient reptiles may have been as diverse as their dinosaur cousins. A good example is Baurusuchus, with dog-like legs and a strong skull.
<h1>Carnufex</h1>
carnufex (butcher)
Historical Period: Middle Triassic (230 million years ago)
Size and weight: About nine feet long, five hundred pounds
Features: Large, short forelimb, bipedal posture
Carnufex, discovered in North Carolina, is one of the largest "crocodiles" in North America and may be the top predator of its ecosystem. Like most early crocodiles, Carnufex walked on later legs.
<h1>Crocodile dragons</h1>
Champsosaurus
Habitat: North America and Western Europe
Historical Period: Late Cretaceous - Early Tertiary Period (50 million to 75 million years ago)
Dimensions and weight: About five feet long, 25-50 pounds
Diet: Fish
Features: Narrow body, long tail, narrow nose and narrow teeth
Champsosaurus is not a true prehistoric crocodile, but a reptile known as choristoderans. It is fully water-based, and because of its resemblance to crocodiles in appearance, many biologists have grouped it with crocodiles.
<h1>Culebrasuchus</h1>
culebrasuchus
The Cultrasuchus of northern America have many similarities with modern caimans, which may be the ancestor of caimans.
<h1>Dakolon
Dakolon
Habitat: Shallow seas in Eurasia and North and South America
Historical Period: Late Jurassic - Early Cretaceous (130-150 million years ago)
Dimensions and weight: About 15 feet long, 1000-2000 pounds
Diet: Fish, squid and other marine life
Features: Dinosaur-like head; Posterior fin
It is referenced to a large number of fierce marine monsters in movies and television, nicknamed "Godzilla". Outwardly, with its head and large posterior fin, the Dakolodrosaurus crocodile seems unlikely to be an agile species, but remains one of the most advanced predators of its time.
<h1>Crocodiles</h1>
Deinosuchus
Habitat: Rivers of North America
Historical period: Late Cretaceous (70 million to 80 million years ago)
Dimensions and weight: up to 33 feet, 5-10 tons
Diet: Fish, shellfish, carrion, including dinosaurs and other creatures
Features: A long body 6 feet long; Tough armor
Dinosaur means horror, and likewise crocodiles are also terrifying crocodiles, one of the largest prehistoric crocodiles ever built, up to 33 feet long from start to finish, very similar to modern crocodiles, so to speak, a perverted version of modern crocodiles.
<h1>Genus Chain crocodile</h1>
The genus Desmatosuchus
Habitat: Forests of North America
Dimensions and weight: Approximately 15 feet long, 500-1000 pounds
Diet: Plants
Features: Crocodile-like posture; Limb unfolding; Armored body with protruding sharp spikes on the shoulders
It is not surprising that Desmatosuchus evolved into such a complex defensive system during the period of the weak
<h1>Genus Schizothorax</h1>
Split-headed crocodile genus Dibothrosuchus
Habitat: East Asia
Historical period: Early Jurassic (180 million to 200 million years ago)
Size and weight: Approximately four feet long, 20-30 pounds
Diet: Meat
Features: Moderate; Long legs; Back armor
A dog-like appearance means more agile than other prehistoric crocodiles
<h1>Diplocynodon
diplocynodon
Habitat: Rivers of Western Europe
Historical Era: Late Eocene - Miocene (20 million to 40 million years ago)
Dimensions and Weight: Approximately 10 feet long and weighs 300 pounds
Diet: Omnivorous
Features: moderate length; Tough armor
Diplocynodon is important because it is one of the few prehistoric crocodiles in Europe.
<h1>Erpetosuchus
erpetosuchus
Historical Period: Late Triassic (200 million years ago)
Dimensions and weight: About a foot long, a few pounds
Food: Insects
Features: Small size, bipedal posture
Crocodiles date back 200 million years to Erpetosuchus, a small-footed bone-boned dragon that wandered the swamps of North America and Europe during the Late Triassic and Early Jurassic Periods. Aside from the head shape, Erpetosuchus didn't look and behave like a modern crocodile.
<h1>Geosaurus</h1>
geosaurus
Habitat: Oceans around the world
Historical period: Middle and late Jurassic (155-175 million years ago)
Dimensions and Weight: Approximately 10 feet long and weighs 250 pounds
Diet: Fish
Features: Slim, long and pointed nose
Geosaurus is the ancient ancestor of modern crocodiles and, due to its life in the ocean, is one of the most difficult marine reptiles to study
