Dino fibres and blood cells found, according to reports in Science (AAAS) news, BBC News 9June 2015, ABC News 10 June 2015, and Nature Communications doi:10.1038/ncomms8352. A group of scientists led by materials scientist Sergio Bertazzo and palaeontologist Susannah Maidment, of Imperial College London, have examined specimens of dinosaur bone from the collection in the Natural History Museum London and have found what appear to be protein fibres and red blood cells.
The researchers used a focussed ion beam to cut into the specimens, giving them a pristine surface to examine with an electron microscope and take samples for chemical analysis using a mass spectrometer. The microscopic study revealed fibres that look like collagen, a tough fibrous protein found in bone, tendons, joint capsules and other connective tissues. The researchers also found oval structures that looked like red blood cells. The mass spectrometer analysis of the fibres showed up amino acid fragments, consistent with those found in collagen. Analysis of the cell-like objects was similar to that of blood.
This is not the first time remains of fibres and blood cells have been found in dinosaur bones, but the previous finds were in exceptionally well preserved specimens. According to Susannah Maidment, the Natural History Museum specimens were “very scrappy, individual broken bones” that were not particularly well preserved. She went on to say: “If you’re finding soft tissues in these kinds of fossils, maybe this kind of preservation might be more common than we realised, and might even be the norm”.
The bones are estimated as being 75 million years old, and have been in the museum collection for over a hundred years. The research team concluded: “Using advanced material characterization approaches, we find that these putative biological structures can be well preserved over geological timescales, and their preservation is more common than previously thought. The preservation of protein over geological timescales offers the opportunity to investigate relationships, physiology and behaviour of long extinct animals”.
Editorial Comment: Let’s be honest! The reason blood cells and protein fibres have not been found in dinosaur bones until recently is because no-one bothered to look for them, and the reason is simple. All present day observations show that proteins and cells break down in a lot less time than one million years, let alone the75 million years these specimens are believed to be. However, now that they have been found, evolutionary scientists are faced with a problem: Do they admit the presence of cells and proteins is evidence that these bones are not that old? Sadly, as the statement from these researchers indicates, scientists would rather believe by faith in some unknown mechanism that goes against our all known observations of how dead cells and proteins decay in order to prop up their belief, also held by faith, in millions of years.
