The body of a mummified dinosaur was discovered by a scientist in Montana, US, and may offer "the best opportunity to bring dinosaurs back to life," according to a documentary.

Former curator of palaeontology at the Phillips County Museum in Malta, US, Nate Murphy is a well-known fossil hunter. He discovered a mummified dinosaur in northeastern Montana in 2001 while conducting excavations there. Mr. Murphy and a group of scientists gently chipped away at the rock to free the extinct animal.

In "Secrets of the Dinosaur Mummy" on Amazon Prime, the 59-year-old explained how the team managed to liberate the fossil.

When we realized we had a fossilized carcass, he added in 2017, "we had to figure out a means to get a six-and-a-half-ton slab of a dinosaur out of the hills of northeastern Montana.

"Leonardo is our best chance to resurrect the dinosaurs,"

The documentary went on to explain how the Brachylophosaurus dinosaur managed to remain absolutely undamaged for so long.

It would require several hundred pounds of dynamite and dozens of bloody fingers to liberate the fossil, the narrator said.

"Leo's body had been covered with silt after being buried in water.

"Shortly after passing away, he was oddly mummified.

"Fossilization then occurred as minuscule sand grains replaced the preserved tissue."

Leonardo was taken by the scientists about 30 miles down the road to Malta, a city on the US West Coast.

They X-rayed the body here inside the Great Plains Dinosaur Museum using cutting-edge technology.

His stomach, heart, and liver were all present and undamaged when they discovered him.

They were able to learn more about the species, though, thanks to the dinosaur's skin.
