Dinosaurs

The majority of dinosaurs were herbivores. Additionally, the populations of herbivorous dinosaurs would have been much larger than populations of similarly sized carnivores.

In 1838, John Estaugh Hopkins was digging and found some interesting bones, which he displayed in his home. In 1858, William Parker Foulke saw the bones. He was interested and dug up the rest of the skeleton. That was the discovery of Hadrosaurus.

Giganotosaurus carolinii lived 97 million years ago. It was a powerful predator, hunting titanosaurid andesaurus delgadoi and limaysaurus tessonei. However, it sacrificed everything else ( Speed, agility, sleek build, and most of all, pack hunting, characteristics seen in its relative mapusaurus roseae. This 95 million year old hunter hunted one of the largest animals of all time: Argentinosaurus huinculensis. For more information, enter the question 'who would win Mapusaurus or Giganotosaurus, in this very website. I also answered that question. ).

Well then, let's settle the debate. Giganotosaurus is powerful, but it sure lacked all those other charcteristics necessary for taking down the gargantuan animal ( Argentinosaurus ) that lived 2 million years after it. Its descendant, mapusaurus, who also lived at the same time of Argentinosaurus, had all the characteristics ( Especially pack hunting, for a lone mapusaurus could get itself killed in a one on one combat with argentinosaurus without the latter getting killed, or, in a smash attack, without getting wounded. Yet, a pack, a minimum of 7, can take down even the 3rd largest dinosaur ( 2nd:Bruhathkayosaurus matleyi, 1st: amphicoelias fragillimus/altus).)necessary to kill the big fat lump of living meat. So it depends which among the animals ( giganotosaurus or argentinosaurus ) is slower. after all, if argentinosaurus is fast enough to smash Giganotosaurus, or Giganotosaurus can kill the big fat lump by ripping its belly if argentinosaurus is to slow to smash. It also depends which among the animals are sick, weak, or inexperienced ( It does not matter if you are young or old, as long as you have all 3 weaknesses or none. Also, I did not consider many against one, like in mapusaurus vs giganotosaurus, for this is a one on one combat. )

But most of all Giganotosaurus will probably win.

Because you have to remember this: carnivores are smarter than dumb herbivores. Carnivores need to think of how to slaughter their prey. So, although Giganotosaurus is dumb ( as I have said in mapusaurus vs giganotosaurus ) it still has to think of how to slaughter.

Soft tissue is rarely found in fossils, and no dinosaur hearts are known to have been preserved. Hence, we have to estimate the size, which depends on many unknowns. To complicate the matter further, different types of dinosaurs would have hearts of different sizes. Unfortunately, nobody knows the size of a dinosaur's heart.

Yes, dinosaurs all hatched from eggs. However, we can not tell if any species were ovoviviparous like some modern reptiles.

Some say that there was never really an astroid storm that killed the Dinosaurs. In fact, in my opinion, I think that at one point a certain species of a dinosaur had gone extinct; and in turn messed up the prehistoric food chain. I can't honestly say that I know if the species were herbivores, carnivores, or omnivores. In response to the astroids, if the astroids did destroy the dinosaurs, how would most of the fossils that were found still fully in tact with each other? Now that right there, is something to think about. (: (I hope this was helpful):D

Possibly. No one knows though, as skin colour doesn't fossilize

cool mild and dry

Yep. That's what Richard Owens thought they were. As things turned out, they weren't that much like modern lizards after all; some people - mostly country folks - thought the fossilized bones looked like those of giant chickens, but their ideas were ridiculed by the scientists of the day. Well, guess what? Modern scientists have been able to analyze some of the DNA of the dinosaurs and they were more closely related to chickens than to lizards!

I don't think there are any moves underway to change the name to "Dinogalliformes" (terrible chickens), though.

Bones were discovered.

The Widest Dinosaur was Diplodocus, genus of dinosaurs of the suborder Sauropoda. One of the largest of the dinosaurs, it lived during the Jurassic period, inhabiting the western part of what is now the United States. Fossil specimens indicate that the reptile attained lengths of up to 26.5 m (87 ft). It was relatively slender, however, and somewhat less bulky than the related Apatosaurus. Diplodocus was a quadruped with a long neck, a low body, and a long tail. A vegetarian, it had a small head with slender teeth and probably grazed in marshes and shallow water.

More than 22 sauropods in the world are discovered,but still many sauropods are to be discovered

yes like the pteranadon

James Kirkland, Robert Gaston, and Donald Burge in 1991.

Yeah, but who cares unless your kid is going to study to be a geologist.

Im not sure which species it it or how long exactly, but i once read the biggest dinosaur is longer than two tennis courts.

Non-avian dinosaur bones (i.e. dinosaurs that are not birds) range from 230 million to 65.5 million years old.

The asteroid that thrust the dinosaurs into extinction is known as the "Chicxulub" asteroid (although this is one of the many competing ideas as to how the dinosaurs became extinct).

Answer 2: 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

cave mans were first

yes but they became extinct 65 million years ago

Animals that evolved in periods before the Mesozoic Era (Age of Dinosaurs) were the pre-dinosaurian reptiles, mammal-like reptiles, fish, amphibians and all or most phyla of today's invertebrates.

Up until this point in prehistory, all animals had their legs positioned outwards from the body like a crocodile's. This made them very slow and awkward to walk around. Then, around 235 million years ago, the first dinosaurs came around. Eoraptor and Eocursor, the first dinosaurs in existence, had their legs positioned dirsctly underneath their bodies. This made the dinosaurs faster, more lightweight, and more agile. Catching prey became a breeze. Predators in the area were no longer a problem. This simple adaptation gave the dinosaurs an edge to become the greatest dynasty of creatures to ever live.

The Tyrannosaurus Rex, or T-Rex.

Plant eating dinosaurs, or herbivores, were more prominent than meat eating dinosaurs. Some included sauropods, hadrosaurs, stegosaurs and ornithopods.
