I have to explain a story or interesting fact about fossils or dinosaurs and I have no, I could help?
When first discovered dinosaur fossils in China, were believed to be the bones of giant dragons.
The first mammals appeared at the end of the Triassic, but they were small creatures, like shrews.
Unlike the current bird, Archaeopteryx was not the peak but sharp jaws with small teeth that served to eat insects.
The wings of a Pteranodon, a flying reptile, measuring nearly seven feet long, twice the average family car.
An important discovery of fossilized footprints of sauropods possible to verify that these animals moved in herds with their calves in the center to protect them.
The saltopus, a Ceratosaurus, measuring just 60 cm long and could have weighed only 2 kg.
The spurs on the legs of a dromaeosaur measured about 15 cm.
Carnosaur larger, like Tyrannosaurus, may have weighed eight tons, more than the African elephant.
The iguanodon was the second dinosaur that was named (in 1825).
The Torosaurus had the largest skull is known. It measured 2.6 m. long including the massive ridge that was.
The hadrosaur (duck-billed) Edmontosaurus could have up to 1,000 teeth in the mouth, all at once.
The bone of the head of Pachycephalosaurus, larger hard headed, could measure up to 25 cm. thick.
With its heavy armor the Ankylosaurus weighed at least 2 tons. Only the tail bone weighed 30 kg.
A stegosaurus weighed over 3 tons, but his brain was the size of a walnut.
The wings of the flying reptile Tupuxuara measured 5.5 m. end to end. But his bones were so light, weighing only 20 kg
Cynodonts onlookers were the ancestors of mammals that now dominate life on Earth.
Theropods were the murderers of the world of dinosaurs.
All theropods were carnivores.
The Celofisio was one of the first theropods, lived 220 million years ago.
The Tyrannosaurus Rex was one of the last theropods, lived 65 million years ago.
Many theropods did not have the fourth and fifth finger.
At least five vertebrae held the pelvis of theropods.
The oldest carnosaur is known Pianisquisaurio, the Jurassic Period.
Many carnosaurs lived for the past 10 million years of the Cretaceous.
We found remains of carnosaurs in North America and South Asia, Africa, Europe and Australia.
The Allosaurus has had more than nine different names since its discovery.
"Trodóntido" means "tooth hurts."
Only three known classes Trodóntidos: the Trodón, the Borogovia, and Saurornitoides.
All the scientists had the Trodón for years was a single tooth.
The trodóntidos are a class of rare dinosaur, dinosaurs were smarter.
