对始新世中期梅塞尔组以下钻孔中的火山碎屑物质进行放射性测年，得出了梅塞尔化石存款的订正数字年龄。因此，格劳阶/盖塞尔塔阶的界线从49 ma上移至47.5ma。讨论了这一变化的后果以及建立盖塞尔塔阶欧洲陆地哺乳动物大带（ELMMZ）（1）进行哺乳动物生物年代学研究的必要性。(C)2005年，Elsevier SAS。All rights reserved.
Radiometric dating of volcaniclastic material from a borehole below the Middle Eocene Messel Formation leads to a revised numerical age of the Messel fossil deposit. Accordingly, the Grauvian/Geiseltalian boundary moves up from about 49 to 47.5 ma. The consequences of this change as well as the necessity of the Geiseltalian European Land Mammal Mega-Zone (ELMMZ)(1) for mammalian biochronology are discussed. (C) 2005 Elsevier SAS.
