Abstract Palynology is used to provide new age controls for the coastal exposures yielding Early Cretaceous vertebrate faunas in the Otway and Gippsland basins, southeast Australia. This work shows all vertebrate-bearing deposits in the Otway Basin are Albian in age. On the eastern margin of Cape Otway, vertebrate-bearing deposits are attributed to the early Albian Crybelosporites striatus Zone, except for one in the younger Coptospora paradoxa Zone. To the west of Cape Otway, the sampled deposits range from the oldest zone in the Albian, the C. striatus Zone, to the C. paradoxa and Phimopollenites pannosus zones, providing a complete section of the Albian stage. In the Gippsland Basin, the structural setting of vertebrate deposits is more complicated and large portions of the coastal exposures consist of repeated sections controlled by small-scale faults. Sites in this region lie below or above the Barremian/Aptian boundary. However, owing to the paucity of age indicator species, some sampled deposits remain undated. In this basin, the ranges of certain key palynomorph species (e.g., Pilosisporites notensis and Pilosisporites parvispinosus) differed from those outlined in some previously published biostratigraphic schemes. The discovery of the angiosperm pollen Clavatipollenites hughesii in the lowermost Aptian deposits of the Gippsland Basin is consistent with its first occurrence elsewhere in Australia and shows it is a reliable indicator for the Aptian stage. This study shows that there is currently a collection bias towards vertebrate assemblages that are latest Barremian and early Albian in age. Barbara E.

澳大利亚维多利亚南部海岸早白垩世脊椎动物床的孢粉年龄测定，以及对该地区孢粉生物地层的影响

摘要 孢粉学用于为海岸暴露提供新的年龄控制，在澳大利亚东南部的奥特韦和吉普斯兰盆地产生早白垩世脊椎动物群。这项工作表明奥特韦盆地中所有含有脊椎动物的沉积物的年龄都是阿尔比安人。在奥特韦角的东缘，除了较年轻的 Coptospora paradoxa 区中的一处外，含有脊椎动物的矿床归属于早期的 Albian Crybelosporites striatus 区。在奥特威角以西，采样的沉积物范围从阿尔比安最古老的带 C. striatus 带，到 C. paradoxa 和 Phimopollenites pannosus 带，提供了阿尔比安阶段的完整部分。在吉普斯兰盆地，脊椎动物沉积物的结构环境更为复杂，大部分沿海暴露区由受小规模断层控制的重复部分组成。该地区的遗址位于 Barremian/Aptian 边界之下或之上。然而，由于年龄指示物种的缺乏，一些取样的矿床仍未确定年代。在该盆地中，某些关键孢粉型物种（例如，Pilosisporites notensis 和 Pilosisporites parvispinosus）的范围与之前发表的一些生物地层方案中概述的范围不同。在 Gippsland 盆地最下部的 Aptian 沉积物中发现的被子植物花粉 Clavatipollenites Huhesii 与其在澳大利亚其他地方的首次发现一致，表明它是 Aptian 阶段的可靠指标。这项研究表明，目前存在对年龄最近的巴雷米亚纪和阿尔比纪早期的脊椎动物组合的收集偏向。Barbara E.
