It's a matter of perspective. If you compare the Age of Dinosaurs (225 - 65 mya) to the Age of Man (35 ky) it's huge, but in comparison to Life on Earth (3.5 by) it's only a brief period. In other words, judged by everything mankind has done or been, dinosaurs are part of the very ancient past, but in light of all that's happened on Earth, dinosaurs are practically modern!
What else can I help you with?
What was around longer birds or dinosaurs?
Both. If you think about it, birds evolved from dinosaurs, and some think birds are the only living dinosaurs left.
Are alligoters dinosaurs?
no. they were around way before dinosaurs.
How long ago did the brachiosaurus live?
Brachiosaurs were the tallest dinosaurs ever to exist. They lived from the late Jurassic around 150 million years ago into the early Cretaceous. Both of those periods were part of the Mesozoic era.
Fossil of dinosaurs are found in Cretaceous rock but not in tertiary rock?
This statement is not accurate. Fossils of dinosaurs have been found in both Cretaceous and Tertiary rock layers. The Cretaceous period ended around 66 million years ago, and the Tertiary period followed, lasting until about 2.6 million years ago. Dinosaurs lived during the Mesozoic Era, which includes the Triassic, Jurassic, and Cretaceous periods.
Is the Crocodile really a descendant of the dinosaur?
Crocodilians are distantly related to the dinosaurs in that they are both Archosaurs, but the former definitely are not descended from the Dinosaurs. They are both members of what is known as a ''crown group'' (the Archosauria). This refers back to a long-extinct bevy of Reptiles that includes the common ancestor of the two living archosaurs -- crocodilians and birds -- and the extinct avian and non-avian dinosaurs. In short, they are related only in that they (crocodilians and dinosaurs) both evolved from the same ancestral reptile.
Where are dinosaurs?
During the Mesozoic Era, between 250 and 65.5 million years ago, dinosaurs lived on all continents, including Antarctica. During that time, small feathered dinosaurs evolved into birds. When the asteroid impact at the end of the Mesozoic wiped out the non-avian dinosaurs (dinosaurs that weren't birds), birds (still a type of dinosaur) survived. Birds survive to this day and live on all continents. Thus, dinosaurs still survive and live on all continents. Dinosaurs are practically everywhere, both non-avian dinosaurs and avian dinosaurs. Birds are considered to be living dinosaurs too. So avian dinos and non-avian dinos have roamed and still roams all continents, in short the whole world. The claim of dinosaurs being extinct is weak and lacks facts and evidence to support the outrageous claim. There are still mixed ideas about how long dinosaurs have been around. Evolutionists claim that dinosaurs existed around 250-65.5 million years ago while creationists claim that dinosaurs have existed since 6000 years ago til today. In short, dinosaurs are everywhere, both avian dinos (in fossils and living creatures) and non-avian dinos (in fossil and living creatures) and the claim that birds are the only true dinos to still survive appears to be an obvious lie.
Ichthyosaurs and plesiosaurs are what?
They are both varieties of aquatic reptile predators that went extinct long ago.
During the 1500s Before meeting who did the knights and samurais both fight?
Dinosaurs Dinosaurs
First living dinosaurs or jellyfish?
i assume your question is as follows: first living; dinosaurs or jelly fish? cnidarians (the phylum that contains both jellies and corals) predate dinosaurs and land animals in general. they predate the dinosaurs by about 400 million years. they've been around for a while, and are some of the oldest known fossils we have found.
How are dinosaurs and humans alike?
Both are vertebrates.
How are dinosaurs and turtles alike?
They are both reptiles
What are some of the physical characterists shared by people and dinosaures?
Both dinosaurs and people have a head and four limbs. Both dinosaurs and people have bones. Dinosaurs were probably warm blooded and had four chambered hearts, also like people. The legs of both people and dinosaurs are erect, rather than sprawled, and the femur has a similar ball and socket joint in both dinosaurs and people. There are probably too many other similarities to list.
