 | Contradictions and puzzles surround the giant fossil Prototaxites. Since the first fossil of Prototaxites was described in 1859, researchers have hypothesized that these organisms were giant algae, fungi, or lichens. A recent study by Dr. Linda Graham and her colleagues published evidence in the February issue of the American Journal of Botany that they believe resolves this long-standing mystery. ...> Full Article |
Is the current flora of New Zealand derived from plants that grew on the supercontinent Gondwana before its breakup, or derived from plants that more recently dispersed to New Zealand? Discovery of new macrofossils and/or detailed examinations of fossil pollen combined with evolutionary analyses may help to answer questions of whether the ancestors of current plants coexisted with dinosaurs in New Zealand.

 | The kelp forests off southern California are considered to be some of the most diverse and productive ecosystems on the planet, yet a new study indicates that today's kelp beds are less extensive and lush than those in the recent past. ...> Full Article |
 | Fossil plants provide clues as to what our planet looked like millions of years ago. Identifying fossil plants can be tricky, however, when plant organs fail to be preserved. Researchers recently discovered abundant fossilized specimens of a conifer (previously known as "Libocedrus" prechilensis) found in Argentinean Patagonia. Characterstics ofthese fossils match those currently found only in tropical, montane New Guinea and the Moluccas. This discovery helps to explain the remarkable plant and insect diversity found in Eocene Patagonia. ...> Full Article |
A team of researchers including a University of Florida paleontologist has used a rich cache of plant fossils discovered in Colombia to provide the first reliable evidence of how Neotropical rainforests looked 58 million years ago.

 | Plant fossils from the same site in northern Colombia where the Titanoboa was found reveal a rainforest very similar to modern neotropical rainforests, but several degrees warmer. ...> Full Article |
 | As flowering plants like giant trees quickly rose to dominate plant communities during the Cretaceous period, the ferns that had preceded them hardly saw it as a disappointment. ...> Full Article |
Unraveling the origins of agriculture in different regions around the globe has been a challenge for archeologists. Now researchers writing in the Proceedings of the National Academy of Sciences report finding evidence of early human experiments with grain cultivation in East Asia. They gathered this information from an unlikely source -- dog and pig bones.

 | Scientists from the University of Bonn are researching which plants giant dinosaurs could have lived off more than 100 million years ago. They want to find out how the dinosaurs were able to become as large as they did. In actual fact such gigantic animals should not have existed. The results of the research have now been published in the journal 'Proceedings of the Royal Society B'. ...> Full Article |
 | The collapse of honeybee colonies across North America is focusing attention on the honeybees' vital role in the survival of agricultural crops, and a new study by University of Florida and Indiana University Southeast researchers shows insect pollinators have likely played a key role in the evolution and success of flowering plants for nearly 100 million years. ...> Full Article |

Long before tourists arrived in the Bahamas, ancient visitors took up residence in this archipelago off Florida's coast and left remains offering stark evidence that the arrival of humans can permanently change - and eliminate - life on what had been isolated islands, says a University of Florida researcher.

Cashew nut fossils have been identified in 47-million year old lake sediment in Germany, revealing that the cashew genus Anacardium was once distributed in Europe, remote from its modern "native" distribution in Central and South America. It was previously proposed that Anacardium and its African sister genus, Fegimanra, diverged from their common ancestor when the landmasses of Africa and South America separated. However, groundbreaking new data in the October issue of the International Journal of Plant Sciences indicate that Europe may be an important biogeographic link between Africa and the New World.
