Once considered beyond the reach of science, insights into the love lives of these extinct giants are emerging
A recently examined snake brood represents the first example of wild facultative parthenogesis in a sexually reproducing species
Evidence is mounting against claims that dinosaurs could not have been endothermic, including a new analysis of fossil microstructures found in ruminants, lizards, dinosaurs and crocodiles
A recently discovered fossil foot hints that tree-dwellers lived alongside species built for walking
What if, by some fluke of evolutionary history, dinosaurs never went extinct? A geologist's imaginings of this scenario now bear a remarkable resemblance to creatures preserved in recent discoveries
Lice lineages began to split and diversify during the late Cretaceous, when dinosaurs, birds and early mammals probably were on the resilient parasites' menus
It never fails. Whenever scientists announce the discovery of a hitherto unknown fossil species intermediate between two already known forms there is always one newspaper or magazine that calls it a "missing link".
