Is It Possible to Clone a Dinosaur?
It's unknown whether this DNA is dinosaurian, or whether it belongs to other life-forms, such as microbes; nondinosaurian animals, such as earthworms; or even paleontologists who have worked with these fossils.
"I've found DNA in dinosaur bone," said Mary Schweitzer, a molecular paleontologist at North Carolina State University. "But we did not sequence it — we couldn't recover it, [and] we couldn't characterize it. Whoever it belongs to is a mystery." [6 Extinct Animals That Could Be Resurrected]
It's no surprise that dinosaur remains contain DNA, she said. Bone is partly made up of a mineral called hydroxyapatite, which has a strong affinity for certain biomolecules, including DNA. In fact, researchers often use hydroxyapatite to purify and concentrate DNA in the lab, Schweitzer said.
"That's one of the reasons that I don't work with DNA myself," Schweitzer told Live Science. "It is too prone to contamination and really difficult to interpret."
Instead, Schweitzer analyzes dinosaur fossils for soft tissue, such as the blood vessels that she and her colleagues found in an 80-million-year-old duck-billed dinosaur. But she has still pondered the steps needed to clone an extinct dinosaur. Here is the science it would take to create an actual "Jurassic Park" dinosaur, according to molecular experts.
The funny thing is that there are no dinosaur bones, just mineral replaced fossils...………….
No bone survives 60 million years
