dinosaurs

Scientists discovered the first ankylosaurid footprints in Canada, proving club-tailed dinosaurs lived in North America during a previously documented fossil gap.

Researchers unveiled on Thursday a newly discovered dinosaur species, discovered in the Montana badlands, that they say challenges assumptions that archeologists made about horned dinosaurs.

Last year, a paper argued that some dinosaurs were as smart as baboons, but some paleontologists now say that's going too far.

Every unearthed scrap of knowledge is valuable in understanding the mid-Cretaceous period, even if it is in the form of one mostly preserved fossil.
