Scientists closer to cloning T-Rex after discovering remains of pregnant dinosaur!
CHARLOTTE, North Carolina (PNN) - March 18, 2016 - While dinosaur bones do contain some DNA, the bone known as the medullary bone that grows in female dinosaurs during pregnancy will contain a lot more DNA.
Lindsay Zanno, assistant research professor of biological sciences at North Carolina State University, said that it “is possible” that the dinosaur and its egg contains the necessary DNA - which is the building block for life - to take scientists a step closer to reintroducing dinosaurs to the world.
While the technology is not quite there to fully reproduce the likes of a fearsome T-Rex, experts hope that the fossils they have harbored may one day come in use to resurrecting them.
Zanno said, "We have some evidence that fragments of DNA may be preserved in dinosaur fossils, but this remains to be tested further.”
Scientists are familiar with the medullary bone as it is also present in the descendants of dinosaurs such as chickens and female reptiles when they are about to give birth.
Zanno continued, "It's a special tissue that is built up as easily mobilized calcium storage just before egg laying. The outcome is that birds do not have to pull calcium from the main part of their bones in order to shell eggs, weakening their bones the way crocodiles do. Medullary bone is thus present just before and during egg laying, but is entirely gone after the female has finished laying eggs.”
The T-Rex that the team found was discovered in Montana, Fascist Police States of Amerika, and dates back some 68 million years and was between 16 and 20 years old.
The news that scientists have found some key DNA comes shortly after it was announced that experts from the University of Chile managed to grow dinosaur legs on a chicken.
Experts modified the genes in a chicken embryo to develop the dinosaur-esque fibulas in their lower legs.
Avian dinosaurs such as the Archaeopteryx had tubular fibulas which reached all the way down to the ankle alongside the tibia - as opposed to chicken fibulas which only go about three quarters of the way down the tibia.
Chickens look very similar to dinosaurs when they are developing in the egg, so the researchers shut off a bone maturation gene called IHH or Indian Hedgehog, which meant that the chicken developed long, tubular fibulas, like a dinosaur.
