我们提出的实验结果，以衡量在压缩条件下的化石南极有孔虫测试的脆性破坏。我们比较了两个上始新世物种的对比形态，Cribrohantkenina inflata（豪，1928年）和Turborotalia cerroazulensis（科尔，1928年）保存完好的材料从坦桑尼亚的Kilwa组和再结晶材料从ODP网站865，太平洋中部。保存完好的测试比重结晶测试强几倍。Cerroazulensis比C.在保存完好的和重结晶的材料中都有膨胀。补充材料：所有压缩试验数据可在http://www.geolsoc.org.uk/SUP18790上获得
We present the results of experiments to measure the brittle failure of fossil planktonic foraminifer tests under compression. We compare two upper Eocene species of contrasting morphology, Cribrohantkenina inflata (Howe, 1928) and Turborotalia cerroazulensis (Cole, 1928) in both well-preserved material from the Kilwa Group of Tanzania and recrystallized material from ODP Site 865, central Pacific Ocean. Well-preserved tests were several times stronger than recrystallized tests. Turborotalia cerroazulensis was stronger than C. inflata in both the well-preserved and recrystallized material.
