Dinosaurs

You would have recognized it. Despite how long ago 67,000,000 years is in comparison to human history, it's not that far back in Earth's 4,200,000,000 years.

There would be dinosaurs, of course, but also flowering plants and fruit trees, mammals like opposums and birds ancestral to ducks. There would also be grass, previously thought to have come along in the later Oligocene, but now recognized as existing as early as the Jurassic.

Okay here are some Dinosaurs with names that start with the letter a. List: Ankylosaurus, Acanthopholis, Acrocanthosaurus, Albertosaurus, Allosaurus, Abelisaurus, Achelousaurus, Actiosaurus, Adasaurus, Aegyptosaurus, Aeolosaurus, Aepisaurus, Afrovenator, Agathaumas, Agilisaurus, Agrosaurus, Alamosaurus, Alectrosaurus, Alioramus, Algosaurus, Aliwalia, Alocodon, Altirhinus, Altispinax, Alvarezsaurus, Apatosaurus, Alwalkeria, Alxasaurus, Amargasaurus, Ammosaurus, Ampelosaurus, Amphicoelias, Amtosaurus, Amphisaurus, Amygdalodon, Amurosaurus, Anchisaurus, Anatosaurus, Anatotitan, Anchisauripus, Anchiceratops, Andesaurus, Angaturama, Anodontosaurus, Anomoepus, Anoplosaurus, Anserimimus, Antarctosaurus, Apatodon, Aragosaurus, Aralosaurus, Araucanoraptor, Archaeoceratops, Archaeoraptor, Archaeornithoides, Archaeornithomimus, Archillobator, Argentinosaurus, Arctosaurus, Arkansaurus, Argyrosaurus, Arrhinoceratops, Arstanosaurus, Asiaceratops, Asiatosaurus, Atlascoposaurus, Atlantosaurus, Astrodon, Atreipus, Aublysodon, Austrosaurus, Avaceratops, Avimimus, Avipes, and Azendosaurus.

Siddhartha Gautama was born in 563B.C.E. His birthplace was the town of Kapilavastu in what is know known as Nepal.

The age of dinosaurs is called the mezoic. this consists of three eras-the creatous, jurrasic and the

herring, cod, halibut, salmon, smelt.

hope this helped!

• We both have the same basic survival needs (food, water, air).
• We both have most of the same internal organs and the same limbs, even if they are arranged somewhat differently. However, we don't have tails like they did.
• We have the same senses (sight, smell, hearing, touch, and taste).
• Some dinosaurs were social and lived in groups, like humans.
• Many dinosaurs raised their young, like humans do.
• Dinosaurs were probably warm blooded and active, like humans, rather than cold blooded and sluggish like most reptiles.

in china people found dinosaurs and thought they were the fossils of dragons

Sixty-six million years ago, dinosaurs had the ultimate bad day. With a devastating asteroid impact, a reign that had lasted 180 million years was abruptly ended. Prof Paul Barrett, a dinosaur researcher at the Museum, explains what is thought to have happened the day the dinosaurs died.

Cavemen and Dinosaurs were not around at the same time.

It was found near the Badlands in Drumheller.

HOMO SAPIENS were so the dominent speices

Dinosaurs became extinct sixty-five million (65,000,000) years before there was anything remotely resembling a human on the plains of Africa.

Not all dinosaurs became extinct 65 million years ago. Some lines continued into semi-modern times and were scouted as the Anakims in the time of Joshua. So men did co-exist with the dinosaurs.

The fossil records for dinosaurs end during the late Cretaceous period. This means that their numbers dwindled so low as to not leave fossil evidence. Their true extinction most like followed quickly.

This is picky, I admit, but since you asked what ERA ended the dinosaurs, I suppose you should have the answer. They died out at the end of the Mesozoic Era (which was, as noted above, also the end of the Cretaceous Period).

However, many scientists no classify birds as dinosaurs, in which case they never fully became extinct.

The official state gemstone of Alabama is the Star Blue Quartz, adopted in 1990.

65 million years ago

you can sell them at a museum and if you are at a desperate museum they will just say that it is worth £10:00p so the solution is go to a very posh museum and go up to someone or to the desk and say can I speak to the person that owns this wonderful museum then they will say its worth depending how old it is about £100,000,00.

The largest dinosaur ever to live is believed to be Argentinosaurus, which could reach lengths of up to 100 feet and weigh as much as 100 tons. This massive herbivore lived during the Late Cretaceous period in what is now Argentina.

No. Turtle are from a branch of reptiles completely separate from dinosaurs.

Mammals actually first came into existence about 220 million years ago, which is about 155 million years before the dinosaurs went extinct, and only about 10 million years after they themselves first evolved. So mammals actually lived alongside the dinosaurs, though played a much smaller role.

Around 65 million years ago, something unusual happened on our planet--and we can see it in the fossil record. Fossils that are abundant in earlier rock layers are simply not present in later rock layers. A wide range of animals and plants suddenly died out, from tiny marine organisms to large dinosaurs.

Species go extinct all the time. Scientists estimate that at least 99.9 percent of all species of plants and animals that ever lived are now extinct. So the demise of dinosaurs like T. rex and Triceratops some 65 million years ago wouldn't be especially noteworthy--except for the fact that around 50 percent of all plants and animals alive at the same time also died out in what scientists call a mass extinction.

A Brief History of Earth

Mass extinctions--when at least half of all species die out in a relatively short time--have happened only a handful of times over the course of our planet's history. The largest mass extinction event occurred around 250 million years ago, when perhaps 95 percent of all species went extinct.

Top Five Extinctions

Cambrian Explosion:

Early life-forms began to flourish. (540 million years ago)

Ordovician-silurian Extinction:

Small marine organisms died out. (440 mya)

Devonian Extinction:

Many tropical marine species went extinct. (365 mya)

Permian-triassic Extinction:

The largest mass extinction event in Earth's history affected a range of species, including many vertebrates. (250 mya)

Triassic-jurassic Extinction:

The extinction of other vertebrate species on land allowed dinosaurs to flourish. (210 mya)

Cretaceous-tertiary Extinction: (65.5 mya)

The Name Game

Scientists refer to the major extinction that wiped out nonavian dinosaurs as the K-T extinction, because it happened at the end of the Cretaceous period and the beginning of the Tertiary period. Why not C-T? Geologists use "K" as a shorthand for Cretaceous. "C" is shorthand for an earlier period, the Cambrian.

Dawn of a New Age

The extinction that occurred 65 million years ago wiped out some 50 percent of plants and animals. The event is so striking that it signals a major turning point in Earth's history, marking the end of the geologic period known as the Cretaceous and the beginning of the Tertiary period.

We are in the Quaternary period now (Holocene Epoch). So it hasn't ended yet.

If you want a fast and light laptop, it sounds like you need something that is great for portability. A netbook will help you check email, do homework, write papers, and surf the web while you're on the go. You can find them from various manufacturers such as HP, Asus, Gateway, and Sony.

The first dinosaurs appeared on earth about 250 million years ago just after the Permian-Triassic mass extinction. The Triassic dinosaurs weren't too fierce and they were mainly neutrally defensive, which means they don't attack unless provoked.
