Scientists have debated where Prototaxites belong in the tree of life for over a century, but new a new study suggests it ...

An ancient and enormous organism called Prototaxites, initially found to be a type of fungus, may actually be an unknown ...

Prototaxites, the first giant organism to live on land, have long been thought to have been some sort of plant, fungus or algae. Now, a new research paper ...

The researchers also studied fossils of extinct fishes dating back almost 400 million years and saw evidence that some of the oldest jawed fishes had bones with joint cavities for articulated ...

Deaths of nearby massive stars may have played a significant role in triggering at least two mass extinction events in ...

How did Earth's earliest seed plants capture pollen to reproduce? A team of scientists has uncovered new clues by ...

Since Prototaxites were discovered in the fossil record in 1843, scientists have debated whether they were early land plants, ...

A supernova — the explosive death of a massive star — can leave behind a black hole or neutron star. These cosmic blasts are element factories, spreading carbon, calcium, and iron across space, ...

New research suggests that powerful star explosions, called supernovae, may have caused at least two mass extinctions in ...
