Summary:
Scientists have used state-of-the-art imaging
techniques to examine the cracks, fractures and breaks in the bones of a
150-million-year-old predatory dinosaur. The research sheds new light,
literally, on the healing process that took place when these magnificent
animals were still alive.

Scientists have used state-of-the-art imaging techniques to
examine the cracks, fractures and breaks in the bones of a 150 million-year-old
predatory dinosaur.
The
University of Manchester researchers say their groundbreaking work – using
synchrotron-imaging techniques – sheds new light, literally, on the healing
process that took place when these magnificent animals were still alive.
The
research, published in the Royal Society journal Interface, took
advantage of the fact that dinosaur bones occasionally preserve evidence of
trauma, sickness and the subsequent signs of healing.
Diagnosis of
such fossils used to rely on the grizzly inspection of gnarled bones and healed
fractures, often entailing slicing through a fossil to reveal its cloying
secrets. But the synchrotron-based imaging, which uses light brighter than 10
billion Suns, meant the team could tease out the chemical ghosts lurking within
the preserved dinosaur bones.
The impact
of massive trauma, they discovered, seemed to be shrugged off by many predatory
dinosaurs – fossil bones often showed a multitude of grizzly healed injuries,
most of which would prove fatal to humans if not medically treated.
Dr Phil
Manning, one of the paper’s authors based in Manchester’s School of Earth,
Atmospheric and Environmental Sciences, said: “Using synchrotron imaging, we
were able to detect astoundingly dilute traces of chemical signatures that
reveal not only the difference between normal and healed bone, but also how the
damaged bone healed.
“It seems
dinosaurs evolved a splendid suite of defence mechanisms to help regulate the
healing and repair of injuries. The ability to diagnose such processes some 150
million years later might well shed new light on how we can use Jurassic
chemistry in the 21st Century.”
He
continued: “The chemistry of life leaves clues throughout our bodies in the
course of our lives that can help us diagnose, treat and heal a multitude of
modern-day ailments. It’s remarkable that the very same chemistry that
initiates the healing of bone in humans also seems to have followed a similar
pathway in dinosaurs.”
Co-author
Jennifer Anné said: “Bone does not form scar tissue, like a scratch to your
skin, so the body has to completely reform new bone following the same stages
that occurred as the skeleton grew in the first place. This means we are
able to tease out the chemistry of bone development through such pathological
studies.
“It's
exciting to realise how little we know about bone, even after hundreds of years
of research. The fact that information on how our own skeleton works can
be explored using a 150-million-year-old dinosaur just shows how interlaced
science can be.”
Professor
Roy Wogelius, another co-author from The University of Manchester, added: “It
is a fine line when diagnosing which part of the fossil was emplaced after
burial and what was original chemistry to the organism. It is only through the
precise measurements that we undertake at the Diamond Synchrotron Lightsource
in the UK and the Stanford Synchrotron Lightsource in the US that we were able
to make such judgments.”
