Our early human ancestors left behind archaeological clues whenever they went, but the ones they left in caves are often particularly well-preserved. From South Africa to Siberia, archaeologists have discovered prehistoric bones, fire ash and even fossilized human footprints inside caves. Early humans...
Rapidly-preserved footprints offer an advantage over archeological or fossilized bone remains in estimating group sizes because these can accumulate over time and do not necessarily reflect a single occupation, unless acatastrophic eventled to a whole group being killed at once. Yet this strength is ...
How dinosaurs moved is not a total mystery — we’ve got some clues. Fossilized footprints and the bones themselves can be parsed, analyzed, and modeled to help inform dino-motion. For example, footprints from 211-million year old therapods — thinkT.rex—helped researchers determinethe mighty...
He lights up when he talks about fossilized dinosaur footprints — trackways — that have been uncovered and taken to partner Stanford University for synchrotron-based imaging. “Like the grooves in a record make music,” he explains, “trackways reveal the characteristics, stride and biomechanics ...
Thus, teachers must first come to terms with the reality that we are living in the twilight era of the windfall gains of modern industrial living brought to us by centuries of increasingly scarce fossilized carbon fuels; only then can we effectively guide our students to face their uncertain ...
