Scientists have discovered red blood cells in dinosaur bones and many say that it could lead to possibility of bringing dinosaurs back to life.

Dinosaur bones from the Cretaceous period were being tested by materials scientist Sergio Bertazzo and his colleague paleontologist Susannah Maidment; the bones are approximately 75 million years old.

Bertazzo and Maidment spotted red blood cells and collagen strands or structural proteins in the specimens after using image enhancement and a mass spectrometer. It left them surprised and speculating whether more existing fossils consist of red blood cells.

According to reports, these findings can help reveal more information when it comes to areas like physiology, behavior and diet of dinosaurs. It is anticipated that these cells may also consist of viable DNA.

In 2008, it was suggested by paleontologist Jack Horner that there could be a better way to make a dinosaur from live genetic material. Dormant genes could be activated by altering the genetics of birds as they are direct descendants of dinosaurs.

A paper was published in the journal ‘Evolution’ by a team at Yale University, in which the team explained their research into reverting a bird’s skull features to the skull of a small dinosaur like an Archaeopteryx or Velociraptor. The scientists conducted experiments on chicken embryos to overturn the molecular process as a result of which dinosaur snouts evolved into beaks.

According to paleontologist and developmental biologist Bhart-Anjan S. Bhullar, “Our goal here was to understand the molecular underpinnings of an important evolutionary transition, not to create a ‘dino-chicken’ simply for the sake of it”.
