The largest animals to ever walk the earth, giant sauropods dominated world ecosystems for 100 million years. New research indicates soft ‘heel pads’ helped them reach their stature.
Collectively, the evidence studied by ichnologists helps to paint a picture of long-gone landscapes and the creatures and plants that populated those spaces.
Two recent discoveries in Alberta and Uzbekistan have identified the top predators in those regions during the Cretaceous period. Fossils that had been in storage for years included the jawbones.
Thanks to our new technique using fossilised tracks, we have been able to learn more about the locomotion of the largest creatures ever to have roamed this planet.
NASA has only mapped 40% of the potentially dangerous asteroids that could crash into Earth. New projects will boost that number, and upcoming missions will test tech that could prevent collisions.
The lack of large numbers of fossils makes it hard to study sexual dimorphism in dinosaurs. But a new statistical approach offers insight into this question and others across science.
