Scientists went to the heart of the El Niño pattern to learn from living and fossil corals. The results show El Niño’s intensifying coincides with global warming.

Island ecosystems feature unique species assemblages with diverse evolutionary histories, but identifying island communities in deep time comes with its own challenges. This Perspective explores the a...

We studied spotted hyena (Crocuta crocuta) encounters with livestock enclosures, an important but understudied stage of the livestock depredation process. Using camera traps, we examined how encounte...

Millions of years ago, a dinosaur dropped dead near Drumheller. Cause of death unknown. Its death was insignificant; until now.

The two possible explanations for the fate of an Albertosaurus found near Drumheller are wildly divergent. But for master’s student Joshua Doyon, presenting the evidence resulted in a breakthrough pub...

Formoso et al. develop a drag-based “slam-start” model to estimate lunge velocity in four mosasaurs from skeletal and muscle reconstructions. Tail curl amplitude mainly drives performance: russellosau...

Uintatheres, mammals belonging to the extinct order Dinocerata, are among the most recognizable of all Paleogene (~66–23 Ma) organisms. Unmistakable for their bizarre skulls with multiple pairs of hor...

The origin of the avian wishbone (furcula)—present since theropod dinosaurs—remains unsolved. Its homology is still debated, with competing hypotheses proposing derivation from the clavicles, the inte...

At 192 years old, Jonathan the giant tortoise is the oldest known living land animal. A new study offers clues as to his incredible longevity.

The plumage of Longipteryx (Aves: Enantiornithes)

A swimming and water-foraging mammaliaform, Megacauda sungei gen. et sp. nov., had a lifestyle analogous to the extant platypus, and was capable of mammal-like swallowing and suckling.

Evidence for dromaeosaurid scavenging on Albertosaurus (Dinosauria: Tyrannosauridae)

Abstract. Sauropodomorph dinosaurs show how appendicular skeletal architecture accommodated extreme increases in body mass. Although sauropod gigantism has

Abstract. Gavialoidea is presently composed of only two extant crocodylian species, the Indian gharial Gavialis gangeticus, and the false gharial Tomistoma

Outgoing Sen. Thom Tillis spoke to MS NOW about regretting his vote to confirm Pete Hegseth and his strained relationship with Trump.

We asked 100 scientists about unsolved problems in their fields. They sent back provocations — on the origins of life, the possibilities for human progress and much more.
