Paleontologists have identified a new species of the extinct armadillo genus Parutaetus from fossilized osteoderms collected in the state of Paraná in...
The so-called Chicxulub impactor was a carbonaceous-type asteroid that had formed beyond the orbit of Jupiter, according to a new paper published in the...
Paleobotanists have described nine new species of the grape family Vitaceae on the basis of 60- to 19-million-year-old fossil seeds discovered in four...
Plant-eating insects are the most diverse group of multicellular organisms on Earth. The most discussed drivers of their inordinate taxonomic and functional...
The evolution of life on Earth has changed dramatically at tens of million-year time scales. However, the causal mechanisms of these changes remain unclear....
The new model provides a high-resolution understanding of how today’s geophysical landscapes were created and how millions of tons of sediment have flowed...
Paleontologists have long debated why groups such as non-avian dinosaurs became extinct whereas mammals and other lineages survived the end-Cretaceous...
Atractosteus grandei lived less than 1,500-2,500 years after the Chicxulub asteroid impact, an event that is widely accepted as a major cause behind the...
Paleontologists have examined tooth morphologies in multiple lineages of sharks that lived during the 27.6-million-year interval around the end-Cretaceous...
Dr. Laura Chornogubsky, a paleontologist in the Museo Argentino de Ciencias Naturales ‘Bernardino Rivadavia’ and CONICET, has described one new genus...
