Resumo |
A faunal boundary found at the base of the Brunhes Chronozone at Sites 658 and 659 confirms previous observations from several locations in the Atlantic Ocean and may be classified as a supraregional "extinction event". Several benthic foraminifer species typical of the Pliocene disappear near the Brunhes/Matuyama boundary, thus marking the upper limit of a faunal zone (faunal unit). Improved chronological dating indicates that the disappearance of these species occurs over a period of about 100,000 yr. |
