Abstract Calpionellids are a group of planktonic microfossils usually occuring in large numbers in pelagic deposits from the upper lower Tithonian to upper Valanginian, and showing a fairly uniform stratigraphic distribution all over the Tethyan Realm and in the southeastern Pacific margin. A preliminary calpionellid scheme was first proposed by Jurgen Remane in 1963 and 1971 consisting of five zones and six subzones informally named: A (A1, A2 and A3), B, C, D (D1, D2 and D3), and E. This biozonal scheme based on specific assemblages, acmes, and partial or total ranges of some calpionellid genera, has constituted, so far, a valid zonal framework towards a homogeneous and universal calpionellid scheme. It only required improvements at the levels of subzones and lower subdivisions. Subsequently, several authors have established numerous new biozonations often inconsistent and varying from one region to another. Such discrepancies noticeably hamper the purpose of calpionellids for biostratigraphic and long-distance correlations. These discrepancies between local schemes often originated from misguided choice of zonal index taxa. Quite a number of subzones are grounded on either rare species with short-range and sporadic occurrences, rare and atypical species, or long-ranging taxa in some stratigraphic levels that yield species with more reliable stratigraphic value. Consequently, further consistent stratigraphical use of this fossil group requires a homogeneous framework with unambiguous definition of zones and subzones, preferably based on specific assemblages. We propose herein a coherent framework of 7 biozones, 16 subzones, and 6 intervals or horizons based upon the analysis of several outcrop sections and the critical insights of formerly published works.

特提斯王国卡皮翁生物区带的讨论和均质卡皮翁利德区划的建议

摘要 Calpionellids 是一组浮游微化石，通常大量存在于上提松阶至上瓦兰吉阶的远洋沉积物中，在整个特提斯界和东南太平洋边缘显示出相当均匀的地层分布。Jurgen Remane 于 1963 年和 1971 年首次提出了初步的 calpionellid 方案，包括五个区和六个非正式命名的子区：A（A1、A2 和 A3）、B、C、D（D1、D2 和 D3）和 E。这迄今为止，基于某些 calpionellid 属的特定组合、顶点和部分或全部范围的生物带计划构成了一个有效的带状框架，以实现同质和通用的 calpionellid 计划。它只需要在分区和更低的细分级别进行改进。随后，几位作者已经建立了许多新的生物区划，这些区划往往不一致，并且因地区而异。这种差异明显妨碍了calpionellids 用于生物地层和长距离相关性的目的。地方计划之间的这些差异通常源于对分区指数分类群的错误选择。相当多的亚区基于短程和零星分布的稀有物种、稀有和非典型物种，或某些地层水平的长程分类群，这些物种产生具有更可靠地层价值的物种。因此，该化石群的进一步一致的地层使用需要一个具有明确定义的带和亚带的同质框架，最好是基于特定组合。我们在此提出了一个由 7 个生物区、16 个亚区、
