Oct. 27, 2016 — Researchers have identified the first known example of fossilized brain tissue in a dinosaur from Sussex. Dinosaurs have a fearsome reputation for their hunting abilities but less so when it comes to their intelligence. A palaeontologist, a medical pathologist, and an orthopaedic surgeon walk into a museum. The soft tissues were preserved by phosphate and iron minerals, and CT (computed tomography) scans show the fossil also contains sediment, as well as fragments of leaves, twigs and bone.Taken together, these observations create a picture of the dinosaur dying in a well-vegetated, swampy environment.

The shape of the homind skull changes dramatically as well, to accommodate the development of a forebrain. The fossilised brain was found by a collector on a beach near Bexhill in Sussex, England. Norman and his colleagues determined the brain tissue was likely from a species similar to Iguanodon, a large herbivorous dinosaur that lived during the … (Danielle Dufault/Royal Ontario Museum/McMaster University)

The rare disease LCH discovered in the remains of a dinosaur that lived in Canada at least 60 million years ago, Tel Aviv University researchers say. There are even hints of deeper tissues that may have formed part of the brain cortex, the functional part of the brain that contains neurons.We think this level of preservation was possible because the brain tissue was effectively pickled before it was mineralised, probably after the dinosaur died in a highly acidic and low-oxygen body of water. "This discovery reminds us of the common biological links throughout the animal kingdom and reinforces the theory that osteosarcoma tends to affect bones when and where they are growing most rapidly,"As the cancer was so advanced, the researchers think it might have spread to other parts of the dinosaur's body, but we don't have any of those tissue samples - such as the spongy lungs - from this ancient animal to make sure. Its head probably became buried in the sediment on a river- or lake-bed, and the lack of oxygen allowed the brain tissues to mineralise before they had a chance to decay.While it is not surprising to find that dinosaurs had brains, it is remarkable that these tissues can be preserved for so many millions of years. "The shin bone shows aggressive cancer at an advanced stage,"After imaging the cancerous shin bone, thin sections were carefully sliced off the fossil and compared to a normal But they suspect the dinosaur died with its herd mates, possibly in a sudden flood event, because the fossil was found in a massive bed of "The fact that this plant-eating dinosaur lived in a large, protective herd may have allowed it to survive longer than it normally would have with such a devastating disease," EvansAnd when we often marvel at the age of dinosaurs and their size,"Evidence suggests that malignancies, including bone cancers, are rooted quite deeply in the evolutionary history of organisms," the authors

This is partly due to the fact that many species have long been thought to have had relatively The fossilised brain was found by a collector on a beach near Bexhill in Sussex, England.

To the modern mind, it does resemble a dinosaur. Lecturer in Palaeobiology, University of Cambridge The Encephalization Quotient, or EQ, measures the size of a creature's brain against the size of the rest of its body and compares this ratio to that of other species of roughly the same size. In fact, it had spread through the bone quite extensively, which the team of medical specialists took as a sign that this centrosaur lived with its cancer for quite some time. An ancestor of humans -- albeit one that is at the root of our family tree -- shared the planet with dinosaurs, a new study concludes. It preserves brain tissue of a large herbivorous dinosaur similar to This revealed evidence of the dinosaur’s meninges, the tough, collagenous outer membranes that protect the main brain.

No, it's not the start of a joke, but the research team that has now diagnosed the first confirmed case of aggressive bone The specimen in question is a fossilised shin bone from What looked - at least on first impression - like a poorly healed fracture turned out to be a tumour engrossing the upper half of the animal's shin bone, or fibula. The centrosaurus was diagnosed with an"Here, we show the unmistakable signature of advanced bone cancer in [a] 76-million-year-old horned dinosaur – the first of its kind,"In humans, osteosarcomas often affect growth-spurting teenagers and young adults. The fossilized tail of a young dinosaur that lived on a prairie in southern Alberta, Canada, is home to the remains of a 60-million-year-old tumor.

Did Humans Walk the Earth with Dinosaurs?

Part of what makes us human beings smart is the enormous size of our brains compared to our bodies; our EQ measures a hefty 5. If an osteosarcoma metastasises - grows beyond the bone - it most often spreads to the lungs, but can also form tumours in other bones, and even the brain.However curious we are about the evolution of diseases such as cancer, soft tissues like tendons, ligaments, bone marrow and tumours, are rarely preserved in fossils.
