Pachycephalosaurs were among some of the last Dinosaur groups to appear. They lived 75-65 mya.
They are named after one of the best-known members of the group, Pachycephalosaurus.
Pachycephalosaurus means "thick-headed reptile," due to the domed and hugely thickened bone on the चोटी, शीर्ष of its skull--like a cyclist's crash helmet.
About 15 feet long from nose to tail, Pachycephalosaurus lived in Montana, South Dakota, and Wyoming.
Stegoceras, which also lived in North America, was about 8 feet long, with a body the size of a goat.
Homalocephale was about 10 feet long and had a flatter skull. It lived in East Asia.
Pachycephalosaurs may have defended themselves द्वारा loweringtheir heads and charging at their enemies.
At breeding time, the males may have engaged in head-butting contests, as some भेड़ and goats do today.

Coelophysis was a small, agile dinosaur that lived at the start of the Age of Dinosaurs, about 220 mya.
A huge collection of Coelophysis fossils were found in the 1940s, at a place called Ghost Ranch, New Mexico.
Hundreds of Coelophysis fossils were preserved together at Ghost Ranch---possibly a herd that drowned in a flood.
Coelophysis was almost 10 feet in total length. Its slim, lightweight build meant that it probably weighed 55-60 pounds.
Coelophysis belonged to the group of डायनासोर known as theropods. It most likely ate small जानवर such as insects, worms, and lizards.
Long, powerful back legs allowed Coelophysis to run fast.
The front limbs were like arms, each with a hand bearing three large, strong, sharp-clawed fingers for grabbing prey.
The birdlike skull was filled with small, sharp teeth.
Coelophysis means "hollow form". It was called that because some of its बोन्स were hollow, like the बोन्स of birds making it lightly built.

The first dinosaur appeared around 230-225 mya, in the middle of the Triassic period.
These डायनासोर were small-to-medium meat eaters with sharp teeth and claws. They ran quickly on their two longer back legs .
Fossils of Herrerasaurus तारीख, दिनांक from 228 mya and were found near San Juan in Argentina, South America.
Herrarasaurus was about 10 feet in total length, and probably weighed 200 pounds.
At about the same time and in the same place as Herrarasaurus, there lived a similar-shaped dinosaur named Eoraptor, which was only 5 feet long.
The name Eoraptor means "dawn plunderer" या "early thief".
Staurikosaurus was a meat eater similar to Herrarasaurus. It is known to have lived about the same time, in present दिन Brazil, South America.
Procompsognathus was another early meat eater. It lived in the late Triassic period in Germany.
Pisanosaurus lived in Argentina in the late Triassic Period, and was only 3 feet long. It may have been a plant eater.

The First living things on earth were single-celled bacteria an cyanobacteria, also known as blue-green algae.
Blue-green algae emerged about 3,500 mya.(million years ago).
It contains chlorophyll and was the first living organism to use photosynthesis या make energy using sunlight.
Over millions of years, the algae was able to produce enough oxygen to help और complex organisms to evolve.
True algae, which is regarded as a plant, evolved around 1,000 mya.
द्वारा 550 mya, multi celled plants began to appear, including seaweeds.
Algae and lichens were the first plants to appear on land.
Bryophyte plants emerged on land around 440 mya. Bryophytes are simple, seedless green plants.
Unlike vascular plants, which rvolved later, bryophytes cannot grow high above the ground because they do not have stems.

Vote to think who आप think is going to win on the picks i will make the fights. there will be 28 डायनासोर in the first round. which ever one gets voted the most wins! Go to picks. there will be 1 dinosaur to be voted to you. i'm not voteing because i made this. so it's up to आप to see who will win tournment. that dinosaur will be the winner forever in this club if he gets voted the most in the final match. So vote for your dinosaur! how the dinosaur loses is he does not get voted the most. so he's out! if it's a tie, i will redo the match until it is over. so good luck!
