Dinosaurs

Nooooooooooooooooooooooooooooo! None were friendly. That's like saying that if u were to smack a lion it wouldn't attack u.

We are in the middle of an ice age right now. It started 2.5million years ago. During this ice age there have been many glacials and many interglacials. We are in an interglacial at present. The previous one was 125,000 years ago and has various names around the world but perhaps the most common name is the Eemian. The present interglacial started, arguably, 20,000 years ago when the extent of the continental ice sheets was at its maximum. Most scientists, thought, consider the start of the present interglacial at about 11,000 years ago when melting really got under way. Interglacials seem to be triggered by Milankovitch cycles with the Obliquity (tilt of the earth) apparently being the most important. Over the past 1 million years of the present 2.5m year ice age, only about every third nudge has resulted in an interglacial. Because of our output of Carbon dioxide, it is thought that the onset of the next glacial will be much delayed.

Adult female dinosaurs generally have a broader pelvis to allow for egg laying. Female dinosaurs that were about to lay eggs grew a type of bone tissue between the marrow and the exterior of their limb bones. It is called medullary bone, and is used to make eggshells. Only female dinosaurs had this.

Some undoubtedly did, but most did not just as some animals today live near volcanoes. Although at some points during the time of the dinosaurs volcanic activity was much higher than it is now, many parts of the world were volcano free.

No full T-Rex skeletons have been found but around 200 bones is a good estimate.

Stegosaurus had bony plates on its back and tail.

Birds are the closest living relatives of spinosaurus and all past dinosaurs.

Macroplata was an early plesiosaur. Their diet consisted of fish.

It´s likely they could perch on two legs. However, looking at their short, webbed, hind legs, it´s likely they had a hard time bouncing around like birds do. Besides, looking at gliding reptiles today, it´s most likely that pterodactyls evolved from four legged reptiles similar to lizards, which suggests that they must have felt more comfortable walking on their four legs instead of two.

Saltopus was a reptile and a close relative of dinosaurs. Because all dinosaurs and nearly all reptiles lay eggs, it is safe to say that Saltopus did, too, even though its eggs have never been found.

There are many theories as to why, but most scientists agree that a huge meteor crashed in the Yucatan Peninsula causing global ash clouds, tidal waves, and many other problems for dinosaurs and other extinct animals.

It is widely accepted that one asteroid with a 6 mile diameter crashed in the Yucatan Peninsula, leaving the Chixculub Crater. However, there are some scientists who believe that there were multiple asteroid impacts at the end of the Mesozoic. Possible other craters include the Boltysh in Ukraine, the Silverpit in the North Sea, and the much more controversial Shiva crater in the Indian Ocean. Some scientists believe that the Chixculub impact predated the extinction of the dinosaurs, and that they were actually wiped out by the Shiva impact.

Velociraptor probably lived less than twenty years maximum, maybe as little as 15. Velociraptor was warm blooded, and it was a small carnivore. Small, warm blooded carnivores don't usually live very long today, and theropod dinosaurs, which were related to Velociraptor, such as Tyrannosaurus and Allosaurus, lived less than 30 years.

"Last"? The most recent discovery: Just a few weeks ago another was discovered in Spain (beginning of August 2009). The youngest dinosaur (if that is what you mean by "last") hasn't been discovered yet because the thousands of species of birds living today could be classified as dinosaurs!

dinosaurs ate a variety of food but it depended on what kind of dinosaur it was. if it was a tyrannosaurus Aka T-Rex it was a carnivore this meant it only ate meat. another dinosaur alamasaurus and if you ever watched land before time it world be called a long neck any way it was a herbavor it ate grass leaves pretty much any edible plants but also some dinosaurs were omnivore that means they ate meat and plants === ===

Honey, A meat eating dinosaur is obversiouly a dinosaur that eats MEAT!!!!!! dahhhhhhh

Example: T-rex, Raptor, Spinosaurus, teradactle

WATCH JURASSIC PARK.

The birds, including the chicken bird, have been shown to be descended from the theropod dinosaurs (which also included the T. rex). It would not be out of order to call birds modern-day dinosaurs.

Scientist believe most if not all the dinosaurs became extinct because of sudden and extreme enviromental and ecological changes on earth. The most popular theory is that a giant comet or asteroid struck in the yucatan peninsula about 65 million year ago.

The lion is called the "King of the Jungle" but that is a misnomer as lions do not live in the jungle and prefer the savanna. The tiger or jaguar would be a more fitting candidate for that title as they do live in the rainforests.

the most resent is that chickens have been related to dinos and the creators of Jurassic park is trying to create a dino-chicken

As far as I know there was no Ice age during the Jurassic era.
