All carnivorous dinosaurs belonged to the suborder Theropoda, meaning 'beast-footed'. This includes dromaeosaurs like Velociraptor, Carnosaurs such as Allosaurus and Tyrannosaurus, and abeliosaurs like Carnotaurus and Majungasaurus. Yes, all of these walked on two feet, but not all two-legged dinosaurs were carnivores. Ornithomimids and Therizinosaurs had teeth designed more for stripping the plant material off of leaves than for active hunting, more likely being herbivores or omnivores.
cavemen and dinosaurs.... :)
they are a great part of history cause they are a fine example of evolution
None. The scorpion is an arthropod, and they existed long before the dinosaurs. Scorpions are anthorpods , they did not evolved from dinosaurs. They existed long before dinosaurs evolved. Its believed that scorpions existed in the Carboniferous Period (430 million years ago). Dinosaurs existed from the Triassic Period (230 million years ago) to the Cretaceous Period (65 million years ago).
Predators - soundtrack - was created on 2010-07-05.
They are carnivores, consumers, and predators.
there were no predators to eat them
Yes. Dinosaurs are prey.
In theory Dinosaurs most likely behaved in a similar manner to modern animals (predators hunted prey, prey ran from predators, Dinosaurs reproduced, dinosaurs evolved). A Dinosaurs ultimate goal was to survive and pass on it's genes. In short a dinosaurs followed the basic principles of nature today.
Bigger dinosaurs, Scarier Dinosaurs, and predators such as Deinosuchus and Liopleurodon
So as to better see predators sneaking up on them.
predators only need to see forward to chase their prey, prey needs to look out for predators
There are different kinds of dinosaurs for the same reasons that their are different kinds of birds and mammals. Dinosaurs, like modern animals, evolved to match their environment and survive to reproduce. Some dinosaurs evolved long necks to eat branches off tall trees, and some dinosaurs evolved sharp teeth to eat other dinosaurs. Some dinosaurs evolved horns and thick skin to defend themselves against predators, and others developed thin frames and long legs to run away from predators. The basic principles of evolution worked the same way for dinosaurs as they do for modern organisms. Dinosaurs evolved into such diverse specihowes because they were the dominant vertebrates for over 160 million years.
Most sizes of squid are subject to predation.
Huge, dragon-like, mysterious, perfect predators, beautiful specimens- what's not to like?
They are both varieties of aquatic reptile predators that went extinct long ago.
The natural enemies of herbivorous dinosaurs were carnivorous dinosaurs, which hunted them. Carnivorous dinosaurs probably hunted smaller carnivorous species for food, and fought with those of their own or other species that were evenly matched over food. However, herbivorous dinosaurs probably only fought with predators or with others of their own species over mates.
Herbivorous dinosaurs, excluding ankylosaurs and stegosaurs, probably fled from predators whenever possible, but would have fought when cornered. Ankylosaurs and stegosaurs were very slow, so they would have stood their ground, using their spiked or clubbed tails as weapons against predators. Some herbivorous dinosaurs, including ceratopsians and pachycephalosaurs, may have fought others of their species over mates.
