What is the middle period of the age of dinosaurs?
The earliest period that dinosaurs existed was the Triassic period, some 225 million years ago. These were not the huge dinosaurs of the later period. Most dinosaurs of that age were small creatures that ate meat and walked on hind legs.

How did one meteor kill whole bunch of dinosaurs?
First off, while we know that the asteroid was the deciding factor, it's very likely that it wasn't the only cause. The number of dinosaur species in the world was shrinking before the impact, and the volcanic activity and changing climate was at least making things very miserable for them. It's more likely that this K-Pg event was just the final nail in the coffin, as it were. Even so, it was a heck of a nail, and it's very important to remember:
- The asteroid that struck the earth was five miles across- as big as Mount Everest.
- The place where it struck, the Gulf of Mexico, happens to have a layer of limestone under it, which provides quite a bit of debris for at least the next three thousand miles to worry about.
- The original clue we received that it was an asteroid- an inch-thick layer of iridium- was found around the globe, meaning that fallout stretched everywhere.
- An impact of that magnitude would have disturbed the plate tectonics to some degree, leading to a higher surge in volcanic activity, earthquakes, and all of the anomalies that come with those.
- The amount of dust and ash sent into the air would have blocked out the sun, preventing its warmth from reaching the surface and its light from cycling photosynthesis in plants. The world would settle into a 'nuclear winter' of sorts, becoming a deep tundra over the several generations that it would have lasted.
Fortunately, the last point brings up a good idea of why what survived did. Dinosaurs, over the course of their 180-million-year hierarchy, began to grow specialized, being only able to live in specific environments and eat certain foods. The ones that did survive (birds, crocodiles, turtles, sharks, and small mammals, for instance) are notorious nowadays for being general specialists, being able to eat practically anything put before them.
The dinosaur with three horns is called the "Triceratops". It is a large plant eater with a frill protecting it's neck. The Triceratops uses the horns for spearing plants, and as weapons to protect itself from predators.
No dinosaurs had hair, although some had feathers. Reptiles with hair or hair like fibers included some types of pterosaurs and thecodonts. Thecodonts are the reptiles that mammals evolved from.
What could a human living now and a dinosaurs living millions of years ago have in common?
They we are both alive
Name three dinosaurs that had wings?
The most famous winged creatures of the dinosaur time were the pterosaurs, an order of flying reptiles often mistakenly called dinosaurs.
However, the dinosaurs world was also inhabited by flying insects, which evolved much earlier, and later, the first birds, which branched off from the dinosaurs.
yes. dinosaurs are reptiles and no reptile can breathe under water.
What is an internal skeleton of a vertebrate animal called?
It is the calcium-rich system of bones that supports the animal's body.
What are reasons for dinosaurs disappearance?
There are many theories, one of them being an asteroid that killed almost all of life on earth millions of years ago. Watch Naked Science on either Discovery or History Channel, it explains the theory and is very interesting.
To stay alive, larger animals need more food than smaller animals. But it also matters whether an animal is warm-blooded or cold-blooded. Since we aren't sure about dinosaurs, figuring out how much food they ate is not quite so simple.
Warm-blooded animals have a higher metabolism: they need more food to stay alive. Cold-blooded animals have a lower metabolism: they need less food to stay alive.
How are dinosaur bones the same as human bones?
There really is no difference. In fact, scientifically, many of their names are the same.
Where did dinosaurs come from?
Dinosaurs evolved from small archosaurs like Lagosuchusand Silesaurus around 230 million years ago during the Middle to Late Triassic period. Since then, they evolved into many groups.

When did the dinosaurs get wiped out?
65 million years ago, most of the dinosaurs were killed by a large asteroid, which landed in the Yucatan Peninsula in east Mexico where a very, very wide and deep crater is there today.
The comet killed the dinosaurs by shooting up a cloud of ash which blocked out the sun over most of the Earth and started an ice age which killed them because they couldn't survive the freezing temperatures.
However, some animals survived by exploding into more hairy or insulated-skinned animals such as the mammoth (now extinct) well that was pointless wasn't it!
The crocodiles and alligators are examples of dinosaurs which have survived the ice age the question was when did the dinosaurs get wiped out and I am sorry that I kept going on and on I realize I made a mistake and I am sorry.
When did dinosaur start to live?
From the fossils of the earliest dinosaurs, scientists have deduced that dinosaurs first appeared on Earth around 250-270 million years ago.
Where are dinosaurs first mentioned in the bible?
Another answer from our community:
There are two sides to this issue, depending on one's view of the historical timeline. For the sake of this answer, let's refer to them as "young earth" vs. "old earth." In no way shall these sections attempt to defend or discredit either position. The Young Earth idea supports the literal interpretation of days and years in Genesis, resulting in a roughly 6,000 year timeline for Earth and the universe. This idea faces the burden of reconciling itself with scientific discoveries and conclusions; some solutions include:
- space-time warping to make light from "billions of light-years away" travel more quickly to our eyes;
- the idea that the universe was created "old," or with everything, including lightspeed forces, already in place to support the entire system instantaneously;
- the Biblical flood accounts for misinterpretations of archeological evidence that supports an old Earth.
In this model, dinosaurs were around until about the time of the flood, and some actually boarded Noah's Ark. Some supporting this view believe that the Old Testament references to "leviathan" (Jonah, Job) and "behemoth" (Job, Psalms) and other large animals were, in fact, references to dinosaurs made before current terminology was accepted. Generic extinction, perhaps as a result of the catastrophic environmental changes brought about as a result of the flood, is credited for the lack of dinosaurs among today's fauna.
What should travelers bring if they were to go to the Jurassic period?
Well, of course, if you went to the Jurassic period you would see many kinds of dinosaurs, wide varieties of vegetation and lush, green forests.
depends if u like meat or what not :D
so ya know you do or you dont :)
What is the classification of the dinosaur tylosaurus?
Allosaurus belongs to the family Allosauridae, in the clade Carnosauria. Carnosauria belongs to the suborder Theropoda, which belongs to the clade Dinosauria. Dinosaurs are reptiles, and reptiles belong to the phylum Chordata and the kingdom Animalia.
What kind of scientist studies dinosaurs and ancient life?
A paleontologist studies dinosaurs and can also delve into the ancient life of humans and other animals too, although archaeologists also study old civillisations.
The diplodocus moved on four legs shaped like columns. This dinosaur tended to move very slowly compared to other dinosaurs.
What kind of pluot is a referred to as a dinosaurs egg?
First of all eggs aren't fruits so obviously a dinosaur egg isn't either it's in the meats group, though you probably aren't ever going to eat a dinosaur egg.
--- but it is a name given to the pluot ... think plum / apricot ....
