摘要
本文讨论了坎塔布连带(西班牙北部)宾夕法尼亚系(米亚奇科夫系,上莫斯科系)石灰岩层中有孔虫的四个特殊情况,并对它们可能的解释提出了一些问题:(1)Pseudostaffella属的真实范围;(2) purella属植物的壁可能有明显的增厚趋势;(3)在部分绒毛中观察到的明显变形的起源,特别是在一些Beedeina标本中,这里解释为可能由于有孔虫疾病引起的改变;(4)对最近发现的融合有孔虫群的观察,推翻了迄今为止解释这些聚集的一个假设,同时为新的解释开辟了新的视角。介绍了一新种purella crassa Villa & Ueno。
Note on A Peculiar Fusuline Sample from the Pennsylvanian of the Cantabrian Zone (Spain): Observations and Intriguing Questions
This paper discusses four peculiar cases of foraminiferal occurrences in a limestone bed of the Pennsylvanian (Myachkovian, upper Moscovian) of the Cantabrian Zone (northern Spain), which raise questions as to their possible interpretation: (1) the true range of the genus Pseudostaffella; (2) the possible marked tendency towards a thickness increase shown by the wall of the genus Putrella; (3) the origin of the apparent deformations observed in part of the fusulines, especially in some Beedeina specimens, here interpreted as alterations probably due to a foraminiferal disease; and (4) the observations made on clusters of recently found fused foraminifera, which invalidate one of the hypotheses so far provided to explain these aggregations while opening perspectives towards new interpretations. A new species, Putrella crassa Villa & Ueno, is introduced.
