Why are dinosaurs described as lords of the earth?
They were long ago the dominant life forms on this planet
What are the names of the baby dinosaurs in ice age 3 dawn of the dinosaurs?
Yolko, Shelly, and Eggwardo
Why didn't dinosurs attack humans?
Dinosaurs went extinct long before humans existed; the two would never have met.
What was bigger the megalodon shark or a dinosaur?
It depends as dinosaurs came in a wide range of sizes. While we often thing of dinosaurs as huge most were actually small. Anchiornis, a dinosaur of the Late Jurassic, was about the size of a dove.BY this measure, megalodon was larger than most dinosaurs, but not all. Some sauropod dinosaurs would have been larger than megalodon.
What is the group of long neck dinosaurs called?
I believe you are referring to the huge, long necked, four legged, plant eating dinosaurs called sauropods. Other long necked dinosaurs include Troodon, Ornithomimids, and Therizinosaurs.
If you're referring to the food, It's a marketing campaign for Bosch, to she that their VitaFresh appliances keep food fresher, longer.
Is there a sea dinosaur called x-predator?
No, but there is one known as Predator-X but it's scientific name is Liopleuredon and it is a "super predator" so it is pretty well known.
However, Liopleuredon was a pleasiosaur, not a dinosaur. Technically there were no sea dinosaurs.
Did dinosaurs eat sweet potatoes?
Sweet potatoes did not exist until about 8,000 years ago. Dinosaurs had already been extinct for 65.5 million years. However, if dinosaurs lived today, some herbivorous and omnivorous dinosaurs probably could eat sweet potatoes.
Did dinosaurs have reproductive organs If so where were they located?
All animals have reproductive organs. The reproductive organs on dinosaurs were most likely located in between the legs (much like the majority of mammalian and reptilians species alive today) The way the tails are mounted the thought is they may have organs like the birds of today.
Yes in a way but no, not exactly.
Studies on bird bones and Dinosaur bones have shown that they are very similar to the branch Dinosauria.
Sharks and crocodiles have evolved from marine dinosaurs which survived the mass extinction.
Some believe that dinosaurs evolved into birds. But this is not correct. Flying creatures were not dinosaurs, they were actually a completely different class called pterosaurs.
So, while dinosaurs themselves are not alive these days, their evolved modern equivalents still walk among us.
Only the evolutionary descendants of the dinosaurs are all still roaming the earth. Two examples are Crocodiles and Tuatara.
See an entire list of creatures that are millions of years old, plants, animals, fungi, bacterias, fish, reptiles, birds etc etc. Note that millions of years cause fundamental changes in a a species such that the descendants will be unrecognizable to the parents.

What animals lived on Pangaea?
Pangaea existed from the Permian, about 299 million years ago, through the Triassic, and into the early Jurassic.
There were very different animals in Pangaea during the Permian than there were in the Triassic because, at the end of the Permian, about 90% of species became extinct in the worst mass extinction in Earth's history.
PermianInsects in Pangaea included beetles, dragonflies, and flies. Early in the Permian, large amphibians and pelycosaur reptiles, like the carnivorous, sail backed Demitrodon, or the herbivorous, sail backed Edaphosaurus. Later in the Permian the archosaurs evolved, which later gave rise to the dinosaurs, pterosaurs, and crocodillians. There were also therapsids, the reptillian ancestors of mammals. TriassicThe temnospndyli, which were large amphibians, and therapsids both survived the Permian extinction event. Archosaurs were the primary terrestrial vertebrates. There were herbivores such as Hyperodapedon, and carnivores like Postosuchus. The first dinosaurs were small meat eaters like Eoraptor, and small, long necked, herbivorous dinosaurs called prosauropods, evolved in Panagaea during the Triassic.Information about the dinosaur egg plum?
it's a cross between a apricot and plum....technically a PLUCOT....called by the name dinosaur egg, because of the speckled coloring.
Did flying birds coexist with land based dinosaurs?
Yes. The earliest birds evolved in the Late Jurassic and greatly diversified through the Cretaceous period, when the dinosaurs were still around.
Was the cobra alive when dinosaurs were alive?
Cobras and other modern snakes were represented by their ancestors that may have had legs and more closely resembled lizards. Those that were adapted to living underground eventually found limb reduction, scales replacing eyelids and thinner bodies to be an advantage for burrowing. By living underground they would be able to avoid predation from and competition with the dinosaurs who were certainly sharing the ecosystem.
Current theory points to global catastrophic climate change, possibly resulting from a meteoric impact, to be the cause of the mass extinction of the dinosaurs some 65 million years ago. Those animals that would have survived to re-populate the earth would have been presented with open niches and no competition. Ancestral snakes would have returned to the surface from their underground tunnels to find ample opportunity to evolve into modern snake forms such as the cobra.
So to answer your question, there were no cobras around with the dinosaurs, but the ancestors of the cobras were around toward the end of the dinosaurs' tenure. The first cobras evolved around 25 million years ago.
What period or era did giant sequoia first appear?
I don't know when the giant sequoia evolved. A close relative, the coastal redwood, evolved in China during the Jurassic period, more than 145 million years ago.
Is there a connection between birds and dinosaurs?
It is generally believed that birds evolved from small, feathered, meat eating dinosaur during the Jurassic period. This is because of the similarities between those dinosaurs and early birds, which include feathers, 'hollow' bones (really they have an internal honeycomb structure), beaks, and other similar features. Additionally, animals that appear to be evolutionary links between birds and dinosaurs exist, such as Archaeopteryx.
How long ago did sauropods live?
Sauropods lived throughout the Mesozoic Era. The earliest sauropods appeared in late Triassic period (200-250 mya), reached their apex in the late Jurassic and their numbers slowly began to decline until their extinction at the end of the Cretaceous, 65 million years ago.
When was Gabija Tonkunas born and when did he died?
It's a she you fudgin idiot. She was born 1999 and didn't die. :P
What is the K-t boundary layer?
K-T stands for Cretaceous-tertiary boundary. The K is used instead of a C to help that there is no confusion between the Cretaceous and Carboniferous Periods; as the Carboniferous Period was among one of the first periods. The K-T boundary is marked by the element named Iridium, the K-T boundary contains approximately 31% iridium, this element is rare on Earth, common in space debris, such as asteroids and meteors/meteorites, such as the one believed to have hit the Earth causing the extinction of the dinosaurs. The Cretaceous was the last of the dinosaur bearing periods. The Tertiary period is the period we as humans live in currently.
How do they know what color a dinosaurs skin is?
No one really knows what color the dinosaurs were. But due to modern analogs (Alligators and birds) we can assume that dinosaurs were green like other reptiles. But unfortunately, we will never know because it is very hard for soft-part of the body to become fossilized.
