摘要
Can Llobateres 1(CLL1;Vallès-Penedès盆地,NE Iberian半岛)中新世晚期(9.8 Ma)的laietanus Hispanophecus代表了西欧大陆最新出现的类人猿化石之一,它们最后一次被记录是在~9.5 Ma。因此,CLL1的古环境与理解欧洲类人猿的灭绝有关。为了完善CLL1的古环境推断,我们应用了基于功能牙冠类型(FCT)变量的生态测量模型,这是一种旨在捕捉草食性大型哺乳动物磨牙咬合形状和磨损表面宏观功能特征的评分方案。CLL1的古温度和古降水量估计是基于已发表的区域回归模型提供的,该模型将大型草食性哺乳动物群落的平均FCT与气候条件联系起来。基于这些估计,以及通过对五个相关生物群落的FCT变量进行规范变量分析进行的基于案例的推理,也试图映射到惠特克目前的生物群落分类。对年平均温度(25°C)和年平均降水量(881 mm)的估计将CLL1归类为热带季节性森林/稀树草原,仅与典型变量分析结果部分一致,后者将CLL1分类为热带雨林的概率更高。以前的生物群落与以前从植物和哺乳动物化石以及初步同位素数据中得出的推断更为一致。CLL1被错误归类为热带森林是由于森林适应分类群与其他适应更开放环境的分类群的混合,因为动物群和植物组成表明附近有密集的湿地/河岸森林和更开放的林地。测试的FCT生态测量方法没有为CLL1提供明确的生物群落分类。尽管如此,我们的结果与其他方法的结果一致,因此表明FCT变量可能有助于研究古环境在时间和空间上的变化,包括导致欧洲中新世类人猿灭绝的变化。
Paleoenvironmental inferences on the Late Miocene hominoid-bearing site of Can Llobateres (NE Iberian Peninsula): An ecometric approach based on functional dental traits
Hispanopithecus laietanus from the Late Miocene (9.8 Ma) of Can Llobateres 1 (CLL1; Vallès-Penedès Basin, NE Iberian Peninsula) represents one of the latest occurrences of fossil apes in Western mainland Europe, where they are last recorded at ∼9.5 Ma. The paleoenvironment of CLL1 is thus relevant for understanding the extinction of European hominoids. To refine paleoenvironmental inferences for CLL1, we apply ecometric models based on functional crown type (FCT) variables—a scoring scheme devised to capture macroscopic functional traits of occlusal shape and wear surfaces of herbivorous large mammal molars. Paleotemperature and paleoprecipitation estimates for CLL1 are provided based on published regional regression models linking average FCT of large herbivorous mammal communities to climatic conditions. A mapping to Whittaker's present-day biome classification is also attempted based on these estimates, as well as a case-based reasoning via canonical variate analysis of FCT variables from five relevant biomes. Estimates of mean annual temperature (25 °C) and mean annual precipitation (881 mm) classify CLL1 as a tropical seasonal forest/savanna, only in partial agreement with the canonical variate analysis results, which classify CLL1 as a tropical rainforest with a higher probability. The former biome agrees better with previous inferences derived from fossil plants and mammals, as well as preliminary isotopic data. The misclassification of CLL1 as a tropical forest is attributed to the mixture of forest-adapted taxa with others adapted to more open environments, given that faunal and plant composition indicates the presence of a dense wetland/riparian forest with more open woodlands nearby. The tested FCT ecometric approaches do not provide unambiguous biome classification for CLL1. Nevertheless, our results are consistent with those from other approaches, thus suggesting that FCT variables are potentially useful to investigate paleoenvironmental changes through time and space—including those that led to the extinction of European Miocene apes.
期刊介绍:
The Journal of Human Evolution concentrates on publishing the highest quality papers covering all aspects of human evolution. The central focus is aimed jointly at paleoanthropological work, covering human and primate fossils, and at comparative studies of living species, including both morphological and molecular evidence. These include descriptions of new discoveries, interpretative analyses of new and previously described material, and assessments of the phylogeny and paleobiology of primate species. Submissions should address issues and questions of broad interest in paleoanthropology.
