Despite the fact that dinosaur bones are often found in different corners of the earth, they do not contain as many can suggest the DNA of these creatures since for many millions of years petrify and turn into minerals. However, recently all changed when experts found remains from which to get a whole chain of ancient deoxyribonucleic acid pangolins.
And it’s not about some harmless herbivorous fat man, but about the most ferocious predator that ever walked on our the planet. Remember how in the science fiction movie Jurassic Park period “Dr. Alan Grant was terrified when he found out that experts cloned and successfully raised the present tyrannosaurus? So, the staff of the University of North Carolina has the same opportunity.
Is it possible to clone a dinosaur?
During excavations in Montana, American paleontologists discovered the skeleton of a pregnant female tyrannosaurus with a medullary bone in rare condition. The age of the remains is about sixty eight million years old. Medullary bone was present in lizards and is today in birds. During pregnancy, females in the bone occur various chemical processes: in the internal spongy substance calcium is accumulated, which is necessary for the formation of an egg shell. However, when the breeding and pregnancy period passes, the bone becomes indistinguishable from the rest of the skeleton of a reptile. Three to four weeks is enough for this.

The female whose remains were found in Montana was at the time of death both times pregnant. Scientists examined her medullary bone and realized that it contains biological material that has not undergone mineralization. This means that in theory, Americans can extract Carnivore dinosaur DNA and clone it. Mary Schweizer, one of authors of the study, says: “We were very lucky to find the remains of a pregnant female tyrannosaurus. Do not bear her eggs then, and it would be another fossil suspended on a fishing line in some museum. Well and so – it is the most valuable and unique find “.
Of course, scientists are not going to clone a ferocious predator and all the more so to create a real Jurassic Park. Not less Americans intend to preserve and preserve dinosaur genetic material for future generations. Who knows – suddenly our descendants will need DNA for some purpose tyrannosaurus.
