Tiny fossils reveal big insights about ant ancestors

Two tiny ant fossils recovered in southern Saskatchewan are helping scientists better understand the evolutionary history of modern ants. Ant fossils dating from 72–56 million years ago are rare. What happened to insects ...

Neutron bone imaging brings T. rex to life

A broken rib from Scotty, the largest T. rex skeleton discovered, is helping scientists uncover new information about life on Earth 66 million years ago. Scotty's rib preserves something rarely seen in the fossil record: ...

Q&A: What dinosaur teeth reveal about diet and evolution

What did dinosaurs eat? Teeth provide important clues to understanding the ecology of dinosaurs, which became extinct approximately 66 million years ago. Their shape, structure and patterns of wear can help scientists reconstruct ...
