Angiosperms (flowering plants) are the most diverse of all major lineages of land plants and the dominant autotrophs in most terrestrial ecosystems. Their evolutionary and ecological appearance is ...

Paleontologists may be on the verge of solving one of the great mysteries in the history of life on our planet – the origin of angiosperms, the flowering plants. The importance of angiosperms cannot ...

They are very tiny, but they are a key source of information when it comes to Earth's evolutionary history: pollen grains are usually no larger than 20 micrometers, or 0.02 millimeters. Using these ...

Fossils of angiosperms first appear in the fossil record about 140 million years ago. Based on the material in which these fossils are deposited, early angiosperms must have been weedy, fast-growing ...

More than 90% of the plants on Earth are angiosperms, flowering plants whose seeds are enclosed inside fruit. And they’re everywhere -- but exactly how and when these plants came to be so ubiquitous ...

They are very tiny, but they are a key source of information when it comes to Earth's evolutionary history: pollen grains are usually no larger than 20 micrometers, or 0.02 millimeters. Using these ...

Journal of Paleontology, Vol. 90, No. 4 (2016), pp. 640-662 (23 pages) Angiosperms first appeared in the fossil record as pollen during the Valanginian–Hauterivian; they spread out of the tropics in ...

Ruolin Wu does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed no relevant affiliations beyond their ...

The discovery of exceptionally well-preserved, tiny fossil seeds dating back to the Early Cretaceous corroborates that flowering plants were small opportunistic colonizers at that time, according to a ...

We may recognize our world by its flowering plants and trees, but evolutionarily speaking angiosperms are the new kids on the block, coming after epochs when giant fungus ruled the Earth and ...

• Background Ovules as developmental precursors of seeds are organs of central importance in angiosperm flowers and can be traced back in evolution to the earliest seed plants. Angiosperm ovules are ...

Red, white and blue flowers help color the July Fourth patriotic season, including these red and white pentas (and their unexpected guest, a giant leopard moth) and a blue lace-cap hydrangea. Kat ...
