Coral reefs made rapid comeback after the greatest mass extinction of all time

  • PDF
1000pa (Oct. 5, 2011) — In the aftermath of the extinction that marked the end of the Paleozoic Era, 252.6 million years ago, reefs made by multicellular animals took less than two million years to reappear and diversify. Until now, it was thought that recovery had taken around ten million years.

These results were obtained by an international team led by four French researchers from the Laboratoire Biogéosciences (CNRS/Université de B...

Dating an ancient episode of severe global warming

  • PDF
1000pa (June 16, 2011) — Using sophisticated methods of dating rocks, a team including University of Southampton researchers based at the National Oceanography Centre, Southampton, have pinned down the timing of the start of an episode of an ancient global warming known as the Paleocene-Eocene thermal maximum (PETM), with implications for the triggering mechanism.

The early part of the Cenozoic era, which started around 65.5 million years...

Plankton fossils tell tale of evolution and extinction

  • PDF
1000pa (Apr. 26, 2011) — Scientists studying the fossils of tiny ocean-dwelling plankton, called foraminifera, have uncovered another piece in the puzzle of why species evolve or become extinct.

The issue of whether extinctions and evolution are controlled more by the environment or by the existing diversity of species in an ecosystem is one that scientists have been debating since Darwin's time.

Using leaves' characteristics improves accuracy measuring past climates

  • PDF
1000pa (Apr. 19, 2011) — A study led by Baylor University and Wesleyan University geologists shows that a new method that uses different size and shape traits of leaves to reconstruct past climates over the last 120 million years is more accurate than other current methods.

The study appeared in the April issue of the journal New Phytologist and was funded by the National Science Foundation.

Oldest known toothache? Infection in jaw of ancient reptilian fossil revealed

  • PDF
1000pa (Apr. 18, 2011) — A reptile that lived 275-million years ago in what is now Oklahoma is giving paleontologists a glimpse of the oldest known toothache.

Led by Professor Robert Reisz, the chair of the Department of Biology at the University of Toronto Mississauga, scientists found evidence of bone damage due to oral infection in Paleozoic reptiles as they adapted to living on land. Their findings, published online in the journal Naturw...
