If you just look at the photo, you will definitely mistake the animals below as one of the prehistoric dinosaurs.

1. Liopleurodon (Pilosaur)
Liopleurodon is a genus of snake-necked lizards and a predator that inhabited the Upper Jurassic waters, about 160-155 million years ago.
They have large body size, adults 6.4 meters long and weigh up to 3 tons. They have a very sensitive sense of smell, and can even smell underwater, so Liopleurodon can sense prey from a great distance.
Kaprosuchus, also known as Boar Crocodile, was known to researchers from an almost complete skull discovered in Niger.
It is estimated that Kaprosuchus is about 6 meters long. With such a large body size, Kaprosuchus can hunt both underwater, and in wetlands.
3. Dimetrodon (reptile-like mammal)
Dimetrodon is a prehistoric reptile that lived in the Permian period. They are often mistaken for a dinosaur with a wing on its back like a sail to help keep the body warm. But later, researchers discovered that Dimetrodon was actually a quadruped.
Dimetrodon is a carnivore that lived 238 million years ago. It has a body size of about 1.7 – 4.6 meters and was extinct for 40 million years before the first dinosaurs appeared on Earth.
4. Elasmosaurus (long neck serow)
Elasmosaurus was one of a group of prehistoric reptiles that lived in the seas some 70 million years ago in the late Cretaceous period. The long-necked serow existed at the same time and was once mistaken for dinosaurs but was not classified as dinosaurs.
A scientist named Edward Drinker Cope was the first to discover the Elasmosaurus fossil in 1868. At that time, he thought that its head was a tail.
5. Quetzalcoatlus (flying lizards)
Many people think that lizards belong to dinosaurs, but the truth is not so.
Quetzalcoatlus is the largest flying lizard in Earth’s history. They have wingspan size of up to 11-12 m, equivalent to that of a small plane. Quetzalcoatlus has an unusually long neck, and when standing upright on the ground its height is comparable to that of an adult giraffe.
Scutosaurus is a genus of reptiles of the Pareiasaur family, inhabiting the Late Permian period. This creature is about 2.5-3 meters long, weighs 1 ton. Along and on both sides of them there are a number of shells to protect the body from predators.
The Prionosuchus is the largest amphibian ever found, with an estimated length of 9 meters. Prionosuchus lived in the Middle Permian period, about 270 million years ago. Their fossils were found in Brazil.
Prionosuchus resembles a crocodile with a long and pointed snout, many sharp teeth, short legs, long body and a tail adapted for swimming. Prionosuchus is a carnivore. Their food is fish and other aquatic animals.
Euparkeria is a relatively small insect eater, about 55 cm long, living here for about 245 million years.
Euparkeria can run very fast on two legs to chase prey. It has a thin body with a long tail and a small head with needle-sharp teeth.
Inostancevia is considered a “killing machine” with nearly 12cm long teeth, the perfect tool for killing large prey. Inostancevia lived about 260 million years ago, its fossils were found in Russia.
Inostrancevia are giant quadruped animals, they can grow up to 4.3 meters if standing upright.
Mosasaurus appeared during the Late Cretaceous period and went extinct during the Cretaceous era.
With a body length of up to 18 meters, Mosasaurus is one of the largest marine reptiles.
