Identifying prehistoric Australian megafauna from fossils may have gotten easier thanks to collagen peptide markers. These peptides can help researchers distinguish different animal genera and perhaps even species. This new information, published in Frontiers in Mammal Science, could not only help researchers identify animals such as a wombat that was the size of a hippo,…
Key Takeaways on the Smallest Dinosaur: At around 30 cm (11 in) in length, a species called Epidexipteryx likely takes the cake as the smallest dinosaur in this group. It lived during the Jurassic period in modern-day China and is known for having four long feathers in its tail. If we’re speaking of creatures that…
If you’ve ever wondered whether the food on your plate could shape your brain’s future, the science is starting to say: yes, it might.

Some of the first hunter-gatherers to arrive in Colombia — and some of the first hunter-gatherers to arrive in all of South America — didn’t stick around. They appeared, then disappeared between 6,000 and 2,000 years ago, only to be replaced by a second population of settlers. That’s what a new study in Science Advances…
Footprints that stroll through a patchy area of Grecian beach 6 million years ago has caused researchers to rethink the timeline of hominin presence outside of Africa. “These are perfectly [obvious] footprints,” says Per Ahlberg, a paleontologist at Uppsala University in Sweden. If these are indeed footprints, then that would put hominins outside of Africa…
A new study in the Oxford Journal of Archaeology has made the shocking discovery that one of the most famous moments in British history never actually happened. The epic and brutal fight between a Roman legion and Britons that violently concluded the Iron Age is a key moment in British history. The battle took place…
An archeological discovery from the Dra’ Abu el-Naga area on Luxor’s West Bank reveals three new tombs of prominent statesmen from Egypt’s New Kingdom era (1550 B.C.E. to 1070 B.C.E.).
