By combining computer tomography—the same technology used for medical scans—with a high-powered particle accelerator, researchers have imaged the network of roots, fungal structures, and soil together...

Infernos ravaged continental expanses of ferns during mass extinction of land and sea animals.

Devonian amber pushes plant resin origin back 65 million years.

The Permian-Triassic mass extinction fundamentally restructured ecosystems, yet it remains unresolved whether ecological collapse unfolded gradually or in discrete steps, and how extinction selectivit...

Angiosperm reproductive evolution is traditionally linked to the end-Cretaceous biotic crisis and subsequent ecological restructuring. Here, we report diverse and unexpectedly large diaspores (dispers...

Remarkably modern marine fish assemblages were established in the tropics within 4 Myr of the K-Pg extinction.

A shift in organic carbon to total phosphorus (Corg/Ptotal) ratios in marine siliciclastic strata from approximately 455 million years ago suggests an earlier-than-previously-thought spread of land pl...

Gardiner et al. reconstruct the diversity of sharks and rays across the past 145 million years using deep learning and an extensive dataset. Their results unveil previously hidden patterns, including ...

Dulvy and colleagues delineate five key challenges to shark conservation, describe their approach for determining priority species and fisheries, and discuss the implications for conservation.

AbstractBackground and Aims. Zosterophyllum, a diverse genus in the global flora spanning the Silurian to Devonian periods, has been extensively documented

Horneophyton lignieri is changing what we know about plant evolution.

The interplay between speciation and extinction rates shapes clade diversity dynamics. Using a novel phylogenetic model that includes living and fossil lineages, the authors estimate speciation and ex...
