Dinosaurs were rulers of the earth for over 160 million yearsDinosaurs were herbivorous, some were carnivorous and some dinosaurs were ferocious predators- How fast do you have to run when a dinosaur is chasing you? Dinosaurs suddenly became extinct about 65 million years ago... ...at the end of the Cretaceous period,
which was a time of high volcanic and tectonic activity. There are a lot of theories
why the extinction occurred. The most widely accepted theory is that an asteroid
impact caused major climactic changes which the dinosaurs couldn't adapt to.
All that's left of the dinosaurs are fossils. Although dinosaurs' fossils have been
known since 1818, the term dinosaur (deinos = terrifying; sauros = lizard) was
coined by the English anatomist Sir Richard Owen in 1842. The only three
dinosaurs known at the time were Megalosaurus, Iguanodon, and Hylaeosaurus,
very large dinosaurs. There are currently over 330 described dinosaur
species and this number is growing... Dinosaur world - Download a Free Game inspired by the BBC TV series
Tyrannosaurus Rex - One of the largest-ever flesh-eating land animals Tyrannosaurus is
also the most famous. For example, it has been featured in more movies than any other
single dinosaur. Tyrannosaurus had a huge skull with powerful jaws lined with 7-inch
(18-cm) serrated teeth. Contrary to earlier conceptions of sluggish mobility,
Tyrannosaurus is now thought by some to have been capable of bursts of up to
30 mph (48 km/h). In contrast to its massive legs, Tyrannosaurus had relatively
short, small arms. Although they seem vestigal and useless, they were powerful
enough to lift over 450 pounds (270 kg). Tyrannosaurus was found in North
America and Asia. The most famous species is Tyrannosaurus rex from North
America... Which was the smartest dinosaur? Although there is no direct way to measure a dinosaur's intelligence,
one of the few possible measures of intelligence might be a large brain in a small
body. The genus that perhaps fits this description best was the Cretaceous bird-like
dinosaur Troodon, which also may have had binocular vision (depth perception) and
excellent eyesight and was built for speed. Even so, this dinosaur was probably
not as "intelligent" as most modern birds and mammals... Velociraptor was a ferocious predator
Why Dinosaurs Had "Fowl" Breath! ScienceDaily (Nov. 7, 2007) A number of studies have shown
that dinosaurs were the direct ancestors of birds and have identified a suite
of avian characteristics in theropods. The dinosaurs we studied from the fossil record
had long uncinate processes similar in structure to those of diving birds. This
suggests both dinosaurs and diving birds need longer lever arms to help them breathe.
Finding these structures in modern birds and their extinct dinosaur ancestors suggests
that these running dinosaurs had an efficient respiratory system and supports the
theory that they were highly active animals that could run relatively quickly when
pursuing their prey... Paleontology, what is that? Paleontology is the study of prehistoric life forms on Earth through the
examination of plant and animal fossils. Evolution is both a scientific fact and a
scientific theory. Evolution is a fact in the sense that life has changed through time.
In nature today, the characteristics of species are changing, and new species are arising.
The fossil record is the primary factual evidence for evolution in
times past.... Dinosaurs are not extinct! There is an almost universal consensus among paleontologists that birds
are the descendants of theropod dinosaurs.
Dinosaurs were an extremely varied group of animals. Some were herbivorous, others
carnivorous. Some
dinosaurs were bipeds, some were quadrupeds, and others, such as Ammosaurus and Iguanodon,
could walk just
as easily on two or four legs. Regardless of body type, nearly all known dinosaurs
were well-adapted for a
predominantly terrestrial, rather than aquatic or aerial, habitat. - Why do Tyrannosaurus like to eat snowmen? There were three dinosaurs stranded on a desert island. One day the first dinosaur
found a bottle in the water and he pointed the bottle out to the other dinosaurs.
The dinosaurs raced out and got the bottle. When the bottle was opened a genie come out.
He gave them one wish each. The first dinosaur wished to be in his homeland and clap,
he was gone. The second dinosaur wished the same as the first dinosaur and clap, he was
gone too. And the third dinosaur said, - What do you get if you cross a dinosaur with a pig?  Books about dinosaurs |
