Why the theory of dinosaurs has become convincing?
This is because there is more evidence to suggest one theory took place over another.
More evidence means a larger likelyhood. But likelyhood alone cannot conclusively present an answer, therefore even though some theories are more PROBABLE, they are only as POSSIBLE as any other theory which has evidence to support it.
Did dinosaurs live in Tennessee?
Actually, They found 2 types of Dinosaur's 1. Found in Williamsburg County is called a Hadrosaur's, it is a plant-eating, duck-billed dinosaur that lived all over The United States. 2. In 1992 and 1994 parts of the fossils of the theropod, a meat-eating dinosaur, was found in Florence County.
What were dinosaurs that walked on four legs called?
Any animal that walks on four legs is called quadrupedal. Quadrupedal dinosaurs include sauropods, stegosaurs, ceratopsians, and ankylosaurs. Hadrosaurs could were usually quadrupedal, but could walk, stand, or run on two legs.
First, they didn't die together. Dinosaurs - a vast group of creatures - all stopped being around about 65 million years ago, probably due to a comet impact. Mammoths, which were just one of many kinds of elephant, died off in recent times, in part from being hunted by people.

It was all forest and water

it used its spikes so that he could defend him self
What is the name for the scientists who dig up for dinosaurs?
The scientists who dig up dinosaurs are called paleontologists. Paleontologists study the history of life on Earth by examining fossils, including dinosaurs, to understand their anatomy, behavior, and evolution. These scientists use various tools and techniques to carefully excavate, preserve, and analyze dinosaur remains found in the field. Their work provides valuable insights into the ancient ecosystems and the history of life on our planet.
Where are dinosaur bones commonly found?
They might be unearthed in almost any state, but Montana, Wyoming and Colorado have been particularly good states for finds of dinosaur bones.
How do you know about the people who lived in Clovis years ago?
By studying artifacts and identifying how they were used.
What are scientists who dig dinosaurs called?
Scientists who dig up, identify, and study all forms of prehistoric creature are called Paleontologists.
Why was it called that Brachiosaurus?
During the bone wars of the mid to late 1800s, paleontologists Cope and Marsh were competing to discover and name the most dinosaurs. As a result, Marsh discovered the already established Apatosaurus next to a new species Camarasaurus skull and named it the Brontosaurus or "Thunder Lizard". The scientific classification laws state that once a species is named in a published journal, that first name is the official name for the species. Therefore the Brontosaurus has been wiped out of the history books and it is once again the Apatosaurus.
Is water today the same as millions of years ago?
yes all water is recycled via the water cycle first evaporated from the sea and joins to form water vapour(clouds), then it condenses as raindroplets falls onto mountains a drains off into the sea via river and lakes then the process starts again

Is there any chance for rebirth of dinosaurs?
There are a few chances: 1) In millions of years, reptiles could evolve and become huge, like dinosaurs, but this would be in millions of years. 2) Scientists have cloned animals, so they may someday (not soon) take DNA from fossils and scientifically re-create dinosaurs. 3) Un-explored jungles may hide dinasaur-like species. Ancient fish have been discovered off the coast of islands that formerly weren't explored alot. Also, the crabfish has been alive since dinasaur days.
What was the loudest dinosaur?
We can't actually know how loud any dinosaurs were. We think those bony hollows in Para's head could have been resonators, but that's only a guess.
How many legs did dinosaurs have?
All dinosaurs had four limbs. Some dinosaurs, like Tyrannosaurus and Allosaurus, were bipeds, which means that they only walked using their two hind limbs. Other dinosaurs, like Stegosaurus, Ankylosaurus, and Diplodocus, always walked on all four limbs, making them quadrupeds. And some dinosaurs walked on all fours, but ran on their two hind legs. Examples of such dinosaurs include Igaunodon and Parasaurolophus.

What did carnivorous dinosaurs eat?
Some dinosaur fossils show evidence of cannibalism. This includes Majungasaurus, Tyrannosaurus, and Allosaurus.

Dinosaurs roamed the earth between about 235 million years ago and 65 million years ago. So, to answer your question, the best guess would be about 235 million years ago or so.
Also dinosaurs laid eggs so they are not actually born but hatched.
