The most primitive among all dinosaurs is Eoraptorlunensis. This name was given to him in 1993, when in the foothills of the Andes, located on the territory of Argentina, in the rocks, the age of which is 228 million years, the researchers discovered the skeleton of this creature. This dinosaur, whose body length reached 1 m, scientists attributed to theropods - predatory dinosaurs from the order of the ptichaetzes.

The most ridiculous dinosaur was named therizinosaurus.
His feet resembled bird's paws, each of which had 4 functional fingers, and on the end of the muzzle of this creature the toothless beak "flaunted".
Sauropods were representatives of the suborder of lizard dinosaurs. From other monsters they were distinguished by an incredibly long neck and tail. Moved sauropods on four limbs. These herbivorous dinosaurs were inhabited most of the land in the Cretaceous and Jurassic periods( 208-65 million years ago).
Scientists believe that the heaviest dinosaurs were:
- Titanosaurs Antarctosaurus giganteus( giant arctic lizards), whose fossil remains were found in Argentina and India. Their weight reached 40-80 tons. And the approximate weight of the Argentine titanosaur( argentinosaurus) could reach up to 100 tons. Such assessments were made in 1994 on the basis of measuring the size of its giant vertebrae.
- Brachiosaurus Brachiosaurus altithorax( handles), which received their name, thanks to their long forelimbs. The weight of these giants was 45-55 tons.
- The Diplodocs Seismosaurus halli( rock-shaking lizards) and Supersaurus vivianae, whose weight exceeded 50 tons, and according to some data could approach 100 tons.
The largest and highest species of dinosaurs
whose skeleton managed to survive completely, was found in the territory of Tanzania, or rather in Tedaguru, Brachiosaurus brancai. His remains were found in the Late Jurassic deposits, formed 150-144 million years ago. Excavations were conducted in 1909-1911 by German expeditions. The preparation of the bones and the assembly of the skeleton took place at the Museum of Natural History at the University of Humboldt in Berlin. The skeleton of the dinosaur was created from bones not one, but several individuals in 1937.The total length of the brachiosaur body was 22.2 m, the height at the withers was 6 m, and the height with the head raised was 14 m. In life, its weight, according to scientists, reached 30-40 tons. The small tibia of another brachiosaur, also stored in the museum, suggests that these dinosaurs could have been much larger.
The longest dinosaurs were the
brachiosaurus Breviparopus, whose body length could be 48 m, and the diplozy Seismosaurus halli, discovered in the US state of New Mexico in 1994, whose body length reached 39-52 m. The basis for obtaining such estimates was the comparison of animal bones.
The smallest dinosaurs are
, which lived in southern Germany and the southeast region of France cosmognathus( a graceful jaw) and a little-studied herbivorous fabrosaur, inhabiting the territory of the American state of Colorado. The length of these creatures, from the tip of the nose to the tip of the tail, was 70-75 cm. The weight of the first reached 3 kg, the weight of the second - 6,8 kg.
Ankylosaurs are considered the most armored
of all dinosaurs that existed on our planet. Their head and back were reliably protected by bone plates, thorns and horns. The width of their body was about 2.5 m. Their main distinguishing feature was the tail, at the end of which there was a huge mace.
The largest traces of the prehistoric reptile
were the traces discovered in 1932 in the territory of Sol-Lake City, the US state of Utah. They belonged to a large hidrosaur( platypus) moving on the hind limbs. The length of the tracks was 136 cm, and the width - 81 cm. In other reports from Colorado and all the same Utah it was said about yet another traces of a width of 95-100 m. According to some reports, the width of the traces of the hind legs of the largest brachiosaurs can reach 100 cm.
The largest skull of
belonged to Torosaurus - a herbivorous lizard carrying around its neck a huge bone shield. The length of this dinosaur could reach 7.6 m, and weight - 8 tons. The length of the skull alone, which was ossified by the "jabot", was 3 m, and its weight was about 2 tons. This "brainy" creature inhabited the territory of the modern American states of Texas and Montana.
In the line of the most toothy dinosaurs
, ornithomimids Pelecanimimus( poultry-like dinosaurs) are on the first place. In their jaws there were more than 220 incredibly sharp teeth.
The holders of the longest claws of
were therizinosaurs found in the Late Cretaceous deposits of the Nemegt basin, located on the territory of Mongolia. The length of their claws along the outer curvature could reach 91cm. In Tyrannosaurus rex, for comparison, this value was 20.3 cm. Terizinosaurus had absolutely no teeth, and the skull was quite fragile. Eat this lizard, according to scientists, termites.
The spinosaur, whose total length reached 9m, could boast of its long claws, and the weight was about 2 tons. In January 1983, a paleontologist, William Walker, discovered a claw 30 cm long belonging to the Spinoza near the English Dorking.
The largest eggs
from all known science dinosaurs put off the 12-meter titanosaur Hypselosaurus priscus, who lived on our planet about 80 million years ago. Shards of his eggs were discovered in October 1961 in the valley of the French River Durance. According to the scientists' assumptions, its dimensions as a whole were 25.5 cm in diameter, 30 cm in length, and its capacity was 3.3 liters.
Paths created by dinosaurs, scientists use to determine the speed of these animals. So the trail found in the territory of the American state of Texas in 1981 allowed the researchers to conclude that a carnivorous dinosaur was able to move at a speed of 40 km / h. It is known that some ornithomimids were able to run even faster. For example, the owner of a large brain, 100-kilogram Dromiceiomimus, who lived at the end of the Cretaceous period in the territory of the modern Canadian province of Alberta, could easily overtake the ostrich, the speed of movement of which can exceed 60 km / h.
The cleverest dinosaurs of
are troodontids, whose brain mass in relation to the mass of their body was comparable to those of the most intelligent birds.
The stegosaurus, which lived 150 million years ago in the territory of the modern American states of Oklahoma, Colorado, Wyoming and Utah, could reach a length of 9 m. However, the brain of this creature did not exceed the size of a walnut, and its weight was only 70 g, which was only 0.002% of the mass of its entire body, equal to an average of 3.3 tons.
