I study how di ...read more

We often associate the word “caveman” with crude simplicity. But based on a new finding, maybe we should, instead, use it as a stand-in for technological innovation.

After analyzing its novel design — a ringed trench rather than a simple pit — and the traces of chemical components left behind by burning, they determined that Neanderthals used it to produce tar from rockrose (Cistus ladanifer). They then employe ...read more

The last species to have them were glyptodonts – large dome-shaped armadillos from South America, and extinct turtle species from South America and Australasia. Before this, only two species of dinosaurs had tail clubs: the quadrupedal armored tanks known as ankylosaurs and the long-necked sauropods. Of those approximately 250 sauropod species, only three were known to have tail ...read more
