Dinosaurs

No, dinosaur fossils do not contain organic material from the dead dinosaur. Over millions of years, the organic materials decay and are replaced by minerals, leaving behind a rock-like structure that preserves the shape and sometimes the fine details of the original bone.

Non avian dinosaurs appeared during the Carnian stage of the Triassic period about 220 million years ago. They diversified in the Jurassic and even more in the Cretaceous, but they died out 65.5 million years ago. All non avian dinosaurs lived during the Mesozoic era, but birds, which are a group of dinosaurs, continue to exist today.

Plants that lived during the Quaternary period include heavy grasses that provided nutrition for animals like the woolly mammoth. With glaciers covering more than 30 percent of the Earth, mammoth steppes, or giant areas of grasslands were the primary plants at the time.

No, dinosaur fossils have not been found in Sri Lanka. The island's geological history indicates that it separated from the supercontinent Gondwana before dinosaurs evolved, so it is unlikely that dinosaurs once lived there.

It depends what you mean by largest thing.
Some plants can be a single organism and cover acres of ground.
Some types of marine life can also be huge in extent, mass or length.
The largest mammal that has ever existed is the Blue Whale.

The amount of food dinosaurs ate daily varied based on their species and size. Larger dinosaurs like the Brachiosaurus may have consumed hundreds of kilograms of food per day, while smaller dinosaurs like the Compsognathus likely ate much less. Studies estimate that some herbivorous dinosaurs could have consumed up to 1 ton of food per day.

Paleontologists now realize that what they thought was a second brain was an enlargement in the spinal cord in the hip area, perhaps containing fat and nerve tissue. This nerve center may have controlled the animal's hind legs and tail and was larger than the animal's tiny brain.

This is a very general question, kind of like asking "What do birds look like?"... there are many different varieties. Some had wings, some were huge, some were small, some ate plants, some ate meat. It all depends on the type of dinosaurs you're referring to.
They were huge reptilian lizards with sharp claws and teeth

There are different kinds of diosaurs. Some yes, are carnivores. Some are herbivores, and only eat plants. Some are omnivores, they eat both meat and plants.

The dinosaur fossil found on Vega Island in 1986 was a theropod dinosaur, specifically a megaraptorid closely related to the Megaraptor. This dinosaur was named "Australovenator wintonensis" and it lived during the Early Cretaceous period approximately 95 million years ago.

"Jurassic" refers to a geologic period that occurred approximately 201 to 145 million years ago, known for the dominance of dinosaurs and the emergence of early mammals and birds. The term is derived from the Jura Mountains in Switzerland where rocks from this period were first extensively studied and identified.

Although no one can determine the EXACT date for anything prehistoric, there are still dating techniques that effectively tell the general lifespan of a given species. Although the range may vary many thousands of years in extreme cases, in comparison to the age of the world (which is about 4.5 billion years old) it is actually pretty good error range for our level of technology. The archaeopteryx is estimated to have lived about 150 million years ago, during the Jurassic period and is evidence of the first feathered prehistoric creature. The dating technique used for this was certainly not carbon-14 dating, because the half life of carbon-14 is only 5730 years, and therefore cannot be used on materials older than 70,000 years old. The method used to date the fossil of the archaeopteryx was probably radiometric dating. with this form of dating, sets of isotopes are examined such as potassium/argon, rubidium/stronium, thorium/lead, argon/argon or uranium/lead. Slight proportionate differences in the isotope levels in whichever isotope set was chosen determines the age of the object. Because the half life of each set of isotopes is so long, they can be used to date objects as old as as the earth, but cannot be used for anything more recent than .7 billion years old. First, a sample is taken from a several rocks and materials around the fossil and excavation site. After the isotope levels have been determined from the objects surrounding the fossil, it is safe to say that the fossil itself must have been approximately the age of the objects it was discovered with. Also, dating methods are tested many times and cross tested between different labs and techniques until there is a consistent result and date range given, to ensure the most accurate result possible. And as always, younger specimens will always have more accurate results than older ones.

Well you could look in several types of areas, like areas of rivers that are not heavily used by people, shores of natural lakes, and depending on where you live exposed rocky banks could all yield fossils. I prefer lakes and rivers.

With a dinosaur fossil, you can learn about the size, shape, and structure of the dinosaur, including its skeletal features, diet, and potential behavior. By studying the fossil, scientists can also infer information about the dinosaur's environment and the time period in which it lived.

That is the question from "Jurassic Park". It is hard to make a living form from DNA but possible. Fortunately nobody ever found Dinosaur DNA and it is scientifically proven that if they found dinosaur DNA it would be to ruined and expired, over the time, to use. The conclusion of these facts is thaot it will ( Thank God ) never be possible to recreate a Dinosaur.

they were from gods imagination . we figure he was like a kid and wanted to see how great his powers were so he made them and realized that they were not what he wanted and created a meteor to destroy them

There are many unconfirmed theories as to what caused the mass extinction of the dinosaurs at the end of the Cretaceous Period.

The most widely supported theory suggests that a large meteor struck the Earth approximately 65 million years ago (known as the Chickulub impact), which caused massive amounts of dust and toxic gas to be released into the atmosphere and "block out" the Sun. A lot of dinosaurs died on impact, however most survived to suffer and die later on down the road. Due to less sunlight/energy penetrating the ozone, plants began to die starving the herbivores. As the herbivores died off the omnivores and carnivores lost their food source and began to die as well. Those that survived hunger and starvation eventually died off due to the climate change. Keep in mind that almost all dinosaurs were cold-blooded and therefor relied on the sun for heat and energy. Evidence that supports this theory includes the Chicxulub Crater, which is thought to have been the result of the meteor impact.

Dinosaurs were already fast becoming endangered species before the Chicxulub impact. Increased volcanic activity such as the Deccan Traps in modern day India was slowly killing many species. Between 68 to 60 million years ago 150,000 km2 of igneous rock was deposited in places more than 2 km thick. The bulk of the eruptions occurred about 66 million years ago near modern day Mumbai. These eruptions lasted as little as 33,000 years but the effect on the environment would have been staggering. Dust and debris thrown into the atmosphere along with sulphur dioxide would have cooled the earth. Also many poisonous gases would also have been released. Studies on modern day birds suggest that these poisonous gases not only directly killed dinosaurs but also caused thinning of the shells of their eggs which meant that many would fail to hatch.

Answer2: Listing some speculations as to what happened to them, Princeton scientist G. L. Jepson stated:

"Authors with varying competence have suggested that dinosaurs disappeared because the climate deteriorated . . . or that the diet did. . . . Other writers have put the blame on disease, parasites, . . . changes in the pressure or composition of the atmosphere, poison gases, volcanic dust, excessive oxygen from plants, meteorites, comets, gene pool drainage by little mammalian egg-eaters, . . . cosmic radiation, shift of Earth's rotational poles, floods, continental drift, . . . drainage of swamp and lake environments, sunspots."-The Riddle of the Dinosaur.

It is apparent from such speculation that scientists are not able, with any certainty, to answer the question: What happened to the dinosaurs?

University of Arizona scientist David Jablonski concludes that 'for many plants and animals, extinction was abrupt and somehow special.Mass extinctions are not merely the cumulative effects of gradual dyings. Something unusual happened.' Their arrival was also abrupt. Scientific American observes: "The sudden appearance of both suborders of the pterosaurs without any obvious antecedents is fairly typical of the fossil record." That is also the case with dinosaurs. Their relatively sudden appearance and disappearance contradicts the commonly accepted view of slow evolution.

Some prehistoric creatures that lived in Alaska include woolly mammoths, mastodons, sabertooth cats, short-faced bears, and giant ground sloths. These creatures roamed the region during the Pleistocene epoch around 2.6 million to 11,700 years ago.

People think they know the reason why the dinosaurs became dead. But now one really knows. But i think i know how they became dead.

A comet crashed into the earth forcing impact onto the mantle witch caused volcanos to erupt killing some dinosaurs but only some then when the comet crashed it vaporized 1/4 of the worlds dinosaurs and sent a cloud of noxious gas into the earths atmosphere blocking out the sun witch killed plant life then killed the plant eaters witch later starved the carnivors killing most of them but some survived but turned into caniballs and then the last one starved to death and died

In a variety of rocks, mostly sedimentary (rocks formed by sand and other material deposited by water or other forms of erosion) but fossils have been found in metamorphic rocks (rocks altered by intense heat or pressure) and even igneous rocks (rocks formed by the cooling of lava or magma), though fossils found in in the latter type of rock are only "mold" type fossils (the lava or magma would have destroyed whatever organic matter was originally in the fossil; another material later could leak into the mold and solidify, creating a rock in the exact shape of whatever had been entombed and destroyed by the lava).

During the Tertiary Period the dominant organisms were mammals. These mammals included the many different types of dinosaurs that were roaming the earth 65 million years ago. Other organisms included bony fish such as bass and trout, flowering plants, insects, and birds.

Yes. We have ample evidence of the dinosaurs that ruled the world until they became extinct around 65 million years ago. Scientists have found skeletons of many dinosaur species and are constantly adding to the list. It is believed that their extinction was caused by a giant meteorite that came down near Mexico, throwing up debris that circled the globe and caused disastrous short-term climate changes to which the dinosaurs could not adapt.

All modern and accepted science indicates that they did exist. There is overwhelming evidence indicating that they did. Some species are represented by modern descendant species (lizards and birds), and some species of fish that existed in the same period have living members in modern times.

you wouldn't! no body knew about them until people starting finding mysteriously large bones all around the world and finally scientists figured it out.

you wouldn't there would no for sure way and even the fossils could be another species than what we thought. No one can really be able to tell what happened years ago even with fossils. There is stil no for certain way.

Sauroposeidon is considered one of the tallest dinosaurs, estimated to have been around 60 feet tall. Its long neck and legs contributed to its impressive height.
