What is a landmass that broke apart 225 million years ago and made today's contientients?
750 million years ago, a single landmass, called Rodinia ( 1.1 billion to 750 million years ago ), broke up into more landmasses. 600 million years ago, they all came together, thus, Pannotia was born, only to break up in 514 million years ago. Once again, they came together to form Pangaea ( 300 million years ago to 200 million years ago ). 100 million years after it was formed, it broke into two; Laurasia the north, and Gondwana the south.
In the present day, they still drift very slowly, but in about 250 million years in the future, a new supercontinent will form...

An herbivore is any animal whose primary diet consists of plants. They are the prey while the carnivores are the hunters.
Are parakeets related to dinosaurs?
It's looking as though they did. The whole class of Aves (birds) seems to owe its existence to dinosaur parents -- although these would most likely have been rather unassumming smallish dinosaurs, not T. rex or Apatosaurus.
Although canaries and parrots are certainly birds, DNA studies have found the most dinosaur-like creatures alive today are -- chickens.
Oviraptors did, but scientists found a fossil of one sitting on a clutch of eggs which looked like the eggs from Protoceratops . They were actually Oviraptor eggs. The scientists thought that Oviraptor died when it found the eggs
Why is the rainforest valuable?
the rain forest is valuable because many medicines are derived from rain forest plants. Most importantly, our oxygen comes from plants, the more plants, the more oxygen.

When did the giganotosaurus live?
Giganotosaurus lived 97 million years ago in what is now Argentina. At the time the area had braided river system, and the local plants would have included conifers, cycads, ferns, horsetails, ginkgoes, and a few very primitive flowering plants. Other dinosaurs that shared this habitat include the sauropods (giant, long necked herbivores) Limaysaurus, Nopcsaspondylus, and Andesaurus, and these may have been prey animals for Giganotosaurus. There were also iguanodonts, relatives of Iguanodon, that definitely would have been prey for the Giganotosaurus. Other predatory dinosaurs that lived here include Ekrixinatosaurus, a 33 to 36 foot long abelisaur, Buitreraptor, a rooster sized dromaeosaur, Bicentenaria, an 8 to 10 foot long carnivore, and Alnashetri.

Would you find a well preserved dinosaur bone in a metamorphic rock?
Though in science you should never say something is not possible, I doubt it. Metamorphic rocks have been pressurized so much that they become a lot smaller than the original sedimentary or igneous rock they came from thus, destroying any evidence of a bone or anything else of that matter.
Were normal birds alive during the Dinosaur times?
birds are dinosaurs some birds that lived with dinosaurs were archeopteryx, confuisosornis, and avivisaurus these creatures are dinosaurs all birds were dinosaurs
What do you call a dinosaur that walks on two legs?
Since the Triassic period was the time of the first dinosaurs, herbivores and carnivores were known to walk on 2 legs. Examples are:
Corythosaurus
Caseosaurus
Technosaurus
Shuvosaurus
Mainly displays for museums - and these tend to have a lot of fake parts. The great majority of dinosaur fossils are sitting in drawers and wrapped up in warehouses. If a particular bone is largely complete, it may be used to make copy castings.
Carnotaurus ate meat (hence its name, which means flesh eating bull). we can tell this from its very sharp fangs and forward facing eyes, a feature that only predators have.
Hope that helped! :-D
The T-rex is probably the most famous of the dinosaurs.
Dinosaurs first appeared during the Triassic period.
Public enthusiasm for dinosaurs skyrocketed in 1854, when the Crystal Palace Park in London unveiled their life-sized sculptures.
I saw a really cool toy Triceratops dinosaur at the store today.
The word "triceratops" means "three-horned face".
Most of the dinosaurs died about 252 million years ago.
Scientists are still debating whether the same series of massive volcanic eruptive events that killed the dinosaurs might have also created the Siberian Traps.
The Sinclair Oil Corporation has a green dinosaur silhouette as their company logo.
Dinosaurs were the dominant terrestrial vertebrates of the Mesozoic period.
The Microraptor had four wings, and is believed to have been capable of powered flight.
It is unknown because the skin of ancient animals decayed millions of years ago.
What things did not exist 60 years ago?
Many things did not exist before the year 1974. Some examples include DVDs, iPods, electronic readers, the internet and laptops.
