Dinosaur Blood and Bone Cells Found: Photos. Dinosaur blood cells extracted from 75-million-year-old fossil - life - 09 June 2015. Watch the birdy (Image: Moviestore/REX Shutterstock) Jurassic Park saw dinosaurs brought back to life based on DNA preserved in the gut of a blood-sucking mosquito entombed in amber.
Now we have found what appears to be real dinosaur blood inside a bog-standard fossil bone. "We stumbled on these things completely by chance," says Susannah Maidment of Imperial College London, whose team was trying to study bone fossilisation by cutting out tiny fragments of fossils. Instead, they found blood-like cells and collagen from 75-million-year-old dinosaur fossils – 10 million years before T. rex appeared. Although the cells are unlikely to contain DNA, those extracted from better preserved fossils using the same technique may do so, she says. And even without DNA, soft tissue cells and molecules could help us learn much more about dinosaur physiology and behaviour, the team says.

Joan Wiffen (1922–2009) Changing scientific ideas Each specialised field of science has key ideas and ways of doing things.
Over time, these ideas and techniques can be revised or replaced in the light of new research. Most changes to key science ideas are only accepted gradually, tested through research by many people. Advances in science and technology All scientists build their research and theories on the knowledge of earlier scientists, and their work will inform other scientists in the future.

Ancient Gondwana Ancient continent of Gondwana thought to be made up of South America, Africa, India, Australia, Antarctica and New Zealand. Meet the Paleontologists. Fossils. Middens. In the past, people threw out their rubbish in particular sites much as we do today.
These sites are called middens and are the archaeological treasure troves of how people used to live. Middens can contain food remains such as shellfish shells, animal bones, ash from fires, broken tools and household objects.

Below, stone walls built more than a thousand years ago by the Moche civilization gave way to a grid of adobe walls put up only recently by what officials said were land speculators. “This site is threatened on every side,” said Luis Jaime Castillo Butters, Peru’s vice minister of cultural heritage as he piloted the drone aircraft. Archaeologists around the world, who have long relied on the classic tools of their profession, like the trowel and the plumb bob, are now turning to the modern technology of drones to defend and explore endangered sites. And perhaps nowhere is the shift happening as swiftly as in Peru, where Dr. 600-year-old canoe found in New Zealand linked to Polynesian sailors. Centuries before Captain Cook explored the South Pacific, Polynesian seafarers in canoes crossed vast swaths of water to colonize lonely islands from Samoa and New Zealand all the way to Hawaii.
But how they managed such a daring feat remains something of a mystery. Now, a roughly 600-year-old canoe discovered in New Zealand may shed some light on the Polynesians’ sailing technology. The vessel, described in the Proceedings of the National Academy of Sciences, is one of just two canoes dating back to such an early time period. A second paper in the same journal finds that shifting ancient wind patterns may have created ideal windows of opportunity for certain generations of sailing Polynesians. The preserved canoe remains were discovered in 2012 on New Zealand’s South Island near the Anaweka estuary, pulled from a sand dune some time after a major storm.
Tips on How to Become a Fossil. Earlier this summer, on a break from scraping Jurassic stone off dinosaur bones at an eastern Utah quarry, I wandered through the fantastical landscape of Arches National Park.
While following the short Park Avenue trail, I noticed that the burnt orange sand running down the middle of the canyon retained the footprints of previous visitors. Looking at the footprints, thinking about how long they might last, a peculiar question struck me: When I die, will I leave any traces behind in the fossil record? Fossils are not just bones. A fossil can be part of an organism's actual form, of course, such as a skeleton or carbonized plant remains. But fossils can also be evidence that an organism passed that way long ago, like footprints or idle twirls left by a twig floating along a river bottom. For most species, becoming a fossil is an accident.
Could footprints be future fossils? Photograph from Travel Ink/Gallo Images/Getty Images. Archaeology. Who invented clothes? A Palaeolithic archaeologist answers. "Who invented clothes?
