Is there a comprehensive list of dinosaurs synonyms with indications of which name is now considered correct? Something like "there's no brontosaurus, there's only Apatosaurus", "there's no Anatotitan, there's only Edmontosaurus" and so on.

Encyclopedia of Life includes information on synonyms (see link for Apatosaurus) - not a list but searchable and often with references and background info. After a quick google search I also found this list from, but I don't know how credible and updated it is and it seems to lack references.

The Ornithischian Dinosaurs

What makes an ornithischian dinosaur? All terrestrial animals and even marine animals derived from terrestrial stocks have hip girdles, or pelvises, and all hip girdles are composed of three bones: the ilium, ischium, and pubis. All ornithischians are united by a pubis pointing backward, running parallel with the ischium. The name "Ornithischia" means "bird-hipped," and birds also have pelvises in which the pubis points backwards. However, birds are more closely related to the Saurischia, or "lizard-hipped" dinosaurs, than to the ornithischian dinosaurs featured on this page.

The hip girdle of a typical ornithischian dinosaur is enlarged in the second diagram at right. In the diagram, the pubis is pale orange, the ilium is red, and the ischium is brown.

There were many kinds of ornithischian dinosaurs, dating back to the early Jurassic. The Ornithopoda included the hadrosaurs ("duck-billed dinosaurs"), the iguanodontids, the heterodontosaurs, the hypsilophodontids, and various other dinosaurs. The Ceratopsia included the horned dinosaurs, the Ankylosauria and Stegosauria (now usually grouped together in the Thyreophora) included various types of armored dinosaurs, and the Pachycephalosauria, the extremely thick-skulled pachycephalosaurs.

Marginocephalia, a group including:
Ceratopsia (horned dinosaurs)
Pachycephalosauria (bone-heads)


Note: Dinosaurs have traditionally been considered a separate group from birds, which evolved from dinosaurs, but modern paleontologists now view birds as survivors of a theropod lineage of dinosaurs. In this classification, all dinosaurs except birds became extinct at the end of the Cretaceous period approximately 65 million years ago, with all dinosaurs that are not birds referred to as dinosaurs or non-avian dinosaurs and birds typically referred to as avian dinosaurs.


The prehistoric reptiles known as dinosaurs arose during the Middle to Late Triassic Period of the Mesozoic Era, some 230 million years ago. They were members of a subclass of reptiles called the archosaurs (“ruling reptiles”), a group that also includes birds and crocodiles.

Scientists first began studying dinosaurs during the 1820s, when they discovered the bones of a large land reptile they dubbed a Megalosaurus (𠇋ig lizard”) buried in the English countryside. In 1842, Sir Richard Owen, Britain’s leading paleontologist, first coined the term 𠇍inosaur.” Owen had examined bones from three different creatures–Megalosaurus, Iguanadon (“iguana tooth”) and Hylaeosaurus (“woodland lizard”). Each of them lived on land, was larger than any living reptile, walked with their legs directly beneath their bodies instead of out to the sides and had three more vertebrae in their hips than other known reptiles. Using this information, Owen determined that the three formed a special group of reptiles, which he named Dinosauria. The word comes from the ancient Greek word deinos (“terrible”) and sauros (“lizard” or “reptile”).

Did you know? Despite the fact that dinosaurs no longer walk the Earth as they did during the Mesozoic Era, unmistakable traces of these enormous reptiles can be identified in their modern-day descendants: birds.

Since then, dinosaur fossils have been found all over the world and studied by paleontologists to find out more about the many different types of these creatures that existed. Scientists have traditionally divided the dinosaur group into two orders: the 𠇋ird-hipped” Ornithischia and the “lizard-hipped” Saurischia. From there, dinosaurs have been broken down into numerous genera (e.g. Tyrannosaurus or Triceratops) and each genus into one or more species. Some dinosaurs were bipedal, which means they walked on two legs. Some walked on four legs (quadrupedal), and some were able to switch between these two walking styles. Some dinosaurs were covered with a type of body armor, and some probably had feathers, like their modern bird relatives. Some moved quickly, while others were lumbering and slow. Most dinosaurs were herbivores, or plant-eaters, but some were carnivorous and hunted or scavenged other dinosaurs in order to survive.

At the time the dinosaurs arose, all of the Earth’s continents were connected together in one land mass, now known as Pangaea, and surrounded by one enormous ocean. Pangaea began to break apart into separate continents during the Early Jurassic Period (around 200 million years ago), and dinosaurs would have seen great changes in the world in which they lived over the course of their existence. Dinosaurs mysteriously disappeared at the end of the Cretaceous Period, around 65 million years ago. Many other types of animals, as well as many species of plants, died out around the same time, and numerous competing theories exist as to what caused this mass extinction. In addition to the great volcanic or tectonic activity that was occurring around that time, scientists have also discovered that a giant asteroid hit Earth about 65.5 million years ago, landing with the force of 180 trillion tons of TNT and spreading an enormous amount of ash all over the Earth’s surface. Deprived of water and sunlight, plants and algae would have died, killing off the planet’s herbivores after a period of surviving on the carcasses of these herbivores, carnivores would have died out as well.

Despite the fact that dinosaurs no longer walk the Earth as they did during the Mesozoic Era, unmistakable traces of these enormous reptiles can be identified in their modern-day descendants: birds. Dinosaurs also live on in the study of paleontology, and new information about them is constantly being uncovered. Finally, judging from their frequent appearances in the movies and on television, dinosaurs have a firm hold in the popular imagination, one realm in which they show no danger of becoming extinct.


Saltasaurus is a titanosaur named for the city of Salta in northern Argentina, where it was discovered. The species was first described in 1980, and it is considered small compared with other titanosaur species, measuring only 12.2 to 12.8 meters (about 40 to 42 feet) long and weighing slightly under 7 metric tons (about 7.7 tons). While several other titanosaurs relied on their sheer size to dissuade predators from attacking them, an analysis of a collection of incomplete fossil skeletons of Saltasaurus suggests that the species employed a different defensive strategy. The titanosaur’s body was covered with osteoderms, or bony armored plates, which made it more difficult for the teeth of a predator to penetrate its flesh.

How Fast Could Dinosaurs Run?

In the movies, meat-eating dinosaurs are portrayed as speedy, relentless killing machines, while plant-eating dinosaurs are fleet, stampeding herd animals. The fact is, though, that dinosaurs differed enormously in their locomotive abilities, and some breeds were faster than others. This article explores how fast dinosaurs could really run.

In Popular Culture

  • Pink dinosaur model at Vernal, Utah. Main article: Dinosaurs in popular culture.
  • By human standards, dinosaurs were creatures of fantastic appearance and often enormous size. As such, they have captured people's imagination and become an enduring part of human popular culture. *Dinosaur exhibitions, parks and museum exhibits around the world both cater to and reinforce the public's interest. The popular preoccupation with dinosaurs is also reflected in a broad array of fictional and non-fictional works.
  • Notable examples of older fictional works featuring dinosaurs include Arthur Conan Doyle's book The Lost World the 1933 film King Kong and Godzilla.
  • Dinosaurs were mentioned on documentary series like Jeff Corwin's Experience, The Crocodile Hunter, Austin Steven's Snakemaster, Extinct or Alive, Crikey! It's the Irwins, and Ultimate Zoo.
