ISLAMABAD: Scientists said they have discovered what appear to be red blood cells and collagen fibers in dinosaur bones, a find that may boost prospects of prising organic remains from a much wider range of fossils.
Using molecular microscopy, a British team analyzed eight bone fragments from dinosaurs that lived some 75 million years ago, in the Cretaceous period, Khaleej times reported.
The fossils were so poorly conserved that it was impossible to tell precisely what type of animal some of them came from, study co-author Sergio
Bertazzo from Imperial College London said.
All the bones are from the Dinosaur Park Formation in Alberta, Canada,
and have been in the Natural History Museum in London since they were collected about 100 years ago.
“What we found are structures that could be original red blood cells
from the dinosaur specimens and also other structures that could be the original collagen fibers,” Bertazzo said..
The team had set out to analyze gaps left in bone by decomposed organic material, instead finding structures that appear to be red blood cells, and fibers similar to collagen, a protein which makes up the bulk of connective tissues in animals.
