The name derived from an Ancient Greek compound meaning "roofed lizard". Scientists have dubbed it so for its titanic size.
Dinosaur Stegosaur lived during the Late Jurassic period, some 155 to 150 million years ago. In 2006, their fossilized remains were found in Portugal, showing that these prehistoric animals were present on the territory of today's Europe as well.
They were large animals at up to 9 m in length, about 4 m high, with a recognizable spiked tail. Body of this dinosaur was covered with two rows of triangular plates, rising vertically along the rounded back.
The plates were connected to the bloodstream, making it possible for the stegosaur to change their color in order to intimidate predators. And the sharp spikes on its tail could inflict
deadly blows to such predators. Stegosaurs were plant eaters.
Named after the ancient Greek word combination that can be translated as "lizard of flat wrist" since it had two pairs of dorsal fins, extended in the form of flat five-fingered wrists.
It lived in the Late Cretaceous period of the geologic timescale, some 85-80 million years ago, in the oceans and seas of today's North America. It grew up to 4.3 meters long, and weighed 1,500 kg. It was carnivorous, feeding on fish and other small marine animals.
Platecarpus was similar in shape to sharks of today, with a spindly body and large pointy head with gill openings without cover. Its jaws were equipped with sharp conical teeth. The body ended up in the form of a long down-turned tail with a large triangular dorsal lobe on it.
Allosaurus - Formidable carnivorous dinosaurs!
Allosaurus was the largest of the carnivorous dinosaurs that lived in the late Jurassic period, some 155 - 150 million years ago. This was a huge bipedal predator whose length could have reached over 12 m. Its weight ranged from one to four tons. Relative to the large and powerful hindlimbs, its three-fingered forelimbs were small, and the body was balanced by a long by a long and heavily muscled tail. Allosaurus lived in prehistoric forests, along rivers. Its remains have been discovered in Europe, Africa, and North America.
As with most dinosaurs, its skull was full of cavities and comprised of narrow strips of bone, making the head highly flexible and agile, able to swallow huge chunks of meat. Its worn out teeth were falling out to be replaced by the growth of new ones.

Dreadnoughtus - the biggest living dinosaur ever!
Recently, new species of dinosaur was discovered in South America - Dreadnoughtus schrani. This dinosaur is till today the biggest dinosaur ever discovered.
Discovered, the largest dinosaur ever Dreadnoughtus Schrani is the largest dinosaur that has ever walked the earth. Keep in mind, however, that even though it had the longest neck of all known creatures, it is not the biggest animal. The #1 place here is held by the Blue Whale.
Dreadnoughtus Schrani lived some 77 million years ago. It could grow to the incredible length of 30 m, and weighed around 65 tons, the equivalent of 12 African elephants. Have a look at the largest dinosaur!

Besti dinosaur pics and toys - Carcharodontosaurus!
Carcharodontosaurus is a genus of carnivorous dinosaurs that existed between 100 and 93 million years ago, during the mid-Cretaceous Period.
It is named after the shark genus Charcarodon (itself named from the Greek “carcharo” meaning “sharp” and “odonto” meaning “teeth”, and “sauros” meaning “lizard”. Carcharodontosaurus was the longest and heaviest known carnivorous dinosaur, with various scientists proposing length estimates ranging between 12 and 13 m, and weight estimates between 6 and 15 metric tons.
This dinosaurs had enormous jaws and serrated teeth up to 8 inches long. The length of the skull itself was 160 cm. Their front three- fingered extremities were short, with sharp claws. They lived on the territory of today`s North Africa.
The name derives from the Ancient Greek "archaios" meaning "ancient", and "pteryx" meaning "feather" or "wing".
Archaeopteryx is the oldest known bird. It lived in the Late Jurassic, around 150 million years ago. Its fossilized
remains have been discovered in Bavaria, Southern Germany.
Archaeopteryx is a genus of small bird-like dinosaur, a transitional form between dinosaurs and birds. It had wings
covered with feathers very similar to modern-day bird feathers, and it could fly. On the other hand, it had jaws with a large number of sharp teeth, three fingers with claws, and a large bony tail, features it shared with other dinosaurs of the time.
Archaeopteryx was similar in size to a raven. It could grow to about 0.5 m in length, and weighed between 0.8 and 1 kg.
Acrocanthosaurus - best dinosaur images!
Acrocanthosaurus (meaning "high spined lizard") is a genus of carnivorous dinosaurs that existed in what is now North America during the Early Cretaceous, between 145 and 100 million years ago. It was one of the largest predators of that period, approaching 13 m in length, and weighing up to 7 tons. It's skull alone was 1.3 m long, with jaws full of curved serrated teeth, as sharp as a scythe (totalling 86 in number, to be exact).
Acrocanthosaurus was a bipedal animal, i.e. moving on its hind legs, with a heavy tail counterbalancing the head and body. It's forelimbs were relatively shorter and each hand bore three clawed digits. The most most notable feature of acrocanthosaurus was a row of tall neural thorns located on the neck, back, hips, and upper tail.
Best pictures of long neck dinosaurs - Seismosaurus!
Seismosaurus was a large long (surapod) necked dinosaur. Seismosaurus use to live 156 million years ago in what is today USA.
Its name is derived from the ancient Greek word combination that could be translated as the “earthquaking lizard”. Apparently because of its enormous size, it was inferred that the earth would shake under its thumping feet. It was a huge plant eating dinosaur, up to 33 m long, weighing between 50 and 75 tons. It had a long neck and a heavy tail as a whip which could inflict deadly blows to any approaching predator. Seismosaurus lived in herds, during the Late Jurassic Period, between 155 and 145 million years ago. Its fossilized remains have been found in New Mexico, USA.
