However, 400 years later, scientists now believe that they could bring the dodo back to life through cloning of some of its closest living relatives.Scientists recently published a paper which identified the overall genomic structure of dinosaurs. The team achieved this by tracing the ancestors (祖...
Although the ancient DNA could not be used to bring dinosaurs back to life, scientists believe they could use the DNA to trace the evolution of life. The findings of the research team were recently published in National Science Review.
Can scientists bring back dinosaurs? Without access to dinosaur DNA,researchers can't clone true dinosaurs. New fossils are being uncovered from the ground every day. ... The cartilage, from the Hypacrosaurus species of the Cretaceous Period, is over 70 million years old but has been calcified...

). Many members are Jurassic forms from around the world, often of medium-large size and rather robust build; but also the celebrity dinosaurs, Spinosauridae, are embedded within Megalosauroidea. We set out to first characterise how key skeletal traits of the hindlimbs of these animals ...
