A bottleneck event caused inbreeding in the last woolly mammoths, but scientists find this was not responsible for their demise on Wrangel Island.
Scientists have unearthed a well-preserved microscopic fossil in Western Australia, challenging timelines and hinting at early eukaryotic life after the Great Oxidation Event 2.4 billion years ago.
We are now learning smaller mammals diversified at a similar rate to larger ones, leading paleontologists to speculate on this explosion in diversity.
A fresh approach to paleoart is providing scientists with the opportunity to paint a vastly different picture of dinosaur life.
