Dinosaurs

The Komodo dragon (Varanus komodoensis) is a large species of lizard not a dinosaur. Dinosaurs evolved from a different branch of reptiles more closely related to crocodiles.

Pterodactyls had teeth that were made for eating meat. Scientist think that they ate fish and small dinosaurs, and that they also scavenged the flesh from dead dinosaurs.

100 million years ago forests were dominated mostly by conifers. Flowering plants were a relatively new development at the time and were fairly primitive. There was no grass.

Pterosaurus

None. Elasmosaurus was a herbivore. It probably was part of the diet of the more famous Permian finback, Dimetrodon

I made a stupid mistake...it all comes of not reading the question and my answer a bit more carefully.

Elasmosaurus was a plesiosaur which, while not a dinosaur, did live in Mesozoic seas as a contemporary, and preyed mainly on fish, I expect. I quite mindlessly confused Elasmosaurus with EDAPHOSAURUS. Edaphosaurus was a synapsid reptile that lived in the late Paleozoic (late Pennsylvanian to the end of the Permian) and was indeed an herbivorous animal, probably a part of the menu of its contemporary, Dimetrodon. Both of these reptiles are considered 'mammal-like' reptiles and were dominant, in terms of numbers, many millions of years before the dinosaurs came onto the scene.

They were obliterated in a mass extinction that was more catastrophic and sweeping than the one that brought the age of dinosaurs to an end.

There were a number of dinosaurs that were related to Stegosaurus and also had two rows of plates on their backs. One example is Kentrosaurus, which was a lot like Stegosaurus but lived in Africa. Another example is Hesperosaurus, which was related to the ancestors of Stegosaurus.

Brachiosaurus is related to several other large dinosaurs, such as Giraffatitan, Lusotitan, Cedarosaurus, and Sauroposeidon. Like all dinosaurs, its closest living relatives are crocodiles and birds.

To be exact, we live in the Phanerozoic Eon, Cenozoic Era, Neogene Period, and Holocene Epoch.

It was found in Argentina.

Dinosaur is a word used to describe the fossilised specimens of what are believed to be lizards from a past era.

Whether a person believes in evolution or not it stands to reason that if the bones are there they are real.

I can't say if all of the colours shapes and histories scientists give the creatures are accurate but there definitely are/were Dinosaurs on this planet.

No, megalodon, properly referred to as Carcharodon megalodon, was not a dinosaur. It was actually a shark, belonging to the same genus as today's great white shark. However, it was bigger, potentially up to 50 feet in length, and fossil evidence suggests that they ate whales.

They died out around sixtyfive million years ago- but I'd imagine they'd be pretty common before then.

THE ONES STANDING CLOSE TO CHICXULUB IN THE YUCATAN WHEN THE COMET/METEOR STRUCK. THEY WERE VAPORIZED. AFTER THAT THINGS GOT DARK AND DEADLY, AND VERY CONFUSING. STARVATION, FIRE, THEN FREEZING COLD (NO SUN)

SO A GOOD ANSWER -- THE FIRST DINOSAURS TO DIE WERE THE LUCKY ONES.

A meteorite impacted Earth. The incoming friction of the meteorite caused widespread wildfires and the burning of Nitrogen in the atmosphere to cause acid rain. dust would have been ejected into the atmosphere, blocking out the Sun, and preventing photosynthesis. Earthquakes and tsunamis would also have resulted from the impact. Because photosynthesis was curtailed, many organisms that could not go without resources for extended periods of time went extinct.

The smallest dinosaur is Microraptor, probably less than 1 ft tall, and is 2 ft long.

about 65 million years ago but no one knows why

Spinosaurus was anywhere from 15 meters to 18 meters long.

dimetrodon was the dominANT SPECIES OF THE permian period

Pterosaurs declined during the Late Cretaceous due to competition with early birds. The last pterosaurs became extinct in the End Cretaceous Mass Extinction, which was caused by an asteroid impact in the Gulf of Mexico.

The first date has to be an estimate, but since the dinosaurs effectively dominated the mammals by the start of the Jurassic (201 mya) we could reasonably credit them with 136 million years "in charge" using 65 mya (the end of the Cretaceous and a spectacular change in the fossil record) as the second.

Actually its not a dinosaur but an insect or the invertebrates but the first dinosaur were the Guang Long(The first evolution of the T-rex like Luci and Todays human)

No. The saber-toothed cats evolved 22 million years ago.

Being extinct, they cannot run at all.

It is surmised from their shape that they could run comparatively quickly, perhaps up to 30 MPH

All the sauropoda were vegetarians; their relatives, the therapoda, were meat-eaters. These were both members of the Saurischia. Another great group, the Ornithischia, were also plant-eaters.

So MOST dinosaurs did not eat meat. This is normal for biospheres; energy comes from the Sun and plants capture some of it, so most animals find a richer food source in plants; only a few can specialize in eating the animals that ate the plants. If there are too many meat-eaters, they devour all the plant-eaters and then starve.
