A team of researchers found blood cells in dinosaur fossils, but the discovery is almost certainly not the start of a real-life "Jurassic Park" story.

According to BBC News, authors of a study published in the journal Nature Communications identified what could be red blood cells in studying well-preserved bones initially found in Canada.

"We still need to do more research to confirm what it is that we are imaging in these dinosaur bone fragments, but the ancient tissue structures we have analyzed have some similarities to red blood cells and collagen fibers," study lead author Sergio Bertazzo, a junior research fellow from Imperial College London's department of materials, said in a press release. "If we can confirm that our initial observations are correct, then this could yield fresh insights into how these creatures once lived and evolved."

CNN noted that, while the discovery might be extremely rare, it will not make cloning dinosaurs any more realistic. DNA is known to degrade quickly after a creature dies and these bones are estimated to be 80 million years old.

However, the study could add to an ongoing debate of how many dinosaurs and which ones were warm- or cold-blooded.

"All of the previous reports of original components of soft tissues in dinosaur fossils have tended to be in specimens that are really exceptionally preserved - one-offs, really, that require special pleading to explain how they got preserved," study co-author Susannah Maidment told BBC News.

Since birds and other animals roaming the Earth are known descendants of dinosaurs, the researchers hope to hold the ancient dinosaur blood cells against their progeny's.

"We still need to do more research to confirm what it is that we are imaging in these dinosaur bone fragments," Bertazzo told BBC News. "If we can confirm that our initial observations are correct, then this could yield fresh insights into how these creatures once lived and evolved."
