A coelacanthi.
They would be killing us and eating us out until WE were extinct so we would be better of without the dinosaurs eating us.But then again it will be nice to see how a dinosaur looks like.
Without mangroves many fish, shore animals and birds would go extinct.
it is home to many animals that could go extinct without there home
without the sun plants would not be able to be produced which would lead to animals not having food, which leads to dinosaurs to have no food and die -hope it helped
Plant life cannot survive without animal life in the world anyway, because plants give out oxygen to the animals because animals need to breathe in order to live. Animals let out carbon dioxide which plants take in, and the cycle repeats.
regeneration allows new limbs to grow for animals such as a star fish. this allows the the chain and hiarchy of animals to expand without easily being extinct.
For one thing, humans wouldn't exist. If the dinosaurs had survived, the small mammals that would have eventually evolved into humans wouldn't have had the chance. Most large mammals - lions, elephants, moose, kangaroos, etc. - wouldn't have had the chance to evolve either. All the big, widespread species would be reptiles or birds.
No, it would have been impossible for humans to arise without the death of the dinosaurs. Actually, dinosaurs dominated the Earth for about 150 million years, which forced the mammals of the time to remain small and insignificant because dinosaurs occupied almost every ecological niche. Only when the dinosaurs became extinct, were mammals given more room to grow and diversify, allowing humans to eventually arise.
The asteroid was about 6 miles across. When it crashed into what is now the Yucatan Peninsula, it threw so much dust into the upper atmosphere, that sunlight was blocked for months. Plants died without sunlight, and the herbivorous dinosaurs died without plants to eat. The carnivores soon died out, too, because their prey was gone. There is also evidence that the Chixculub impact preceded the dinosaur extinction by hundreds of thousands of years, until another, possibly larger asteroid struck eliminated the non avian dinosaurs once and for all. Even without the asteroids, dinosaurs were already dealing with the negative affects of climate change.
A dinosaur!!!!!!!!!!!!!!!(some dinosaurs) None alwaysattack without reson. Most animals attack because they have rabies, babies, are injured, sick, staving, frightend. Animals always have a reson.
Without mentioning dinosaurs specifically,the bible does refer to groups of creatures that may include them Genesis 1:25 all the creeping animals of the ground Genesis 1:21 New American Bible Great sea;creatures or monsters Genesis 1:25 the wild animals of the earth
The Dinosaurs Needed Tails To Keep Their Balance, Without the tail, the dinosaurs will fall over.
