Marine microfossils record the environmental, ecological, and evolutionary dynamics of past oceans in temporally expanded sedimentary archives. Rapid imaging approaches provide a means of exploiting the primary advantage of this archive, the vast number of fossils, for evolution and ecology. Here we provide the first large scale image and 2D and 3D shape dataset of modern planktonic foraminifera, a major microfossil group, from 34 Atlantic Ocean sediment samples. Information on more than 124,000 objects is provided, including general object classification for 4/5ths of the dataset (~ 99,000 objects). Of the ~ 99,000 classifications provided, more than 61,000 are complete or damaged planktonic foraminifera. Objects also include benthic foraminifera, ostracods, pteropods, spicules, and planktonic foraminifera test fragments, among others. This dataset is the first major microfossil output of a new high-throughput imaging method (AutoMorph) developed to extract 2D and 3D data from photographic images of fossils. Our sample preparation and imaging techniques are described in detail. The data provided here comprises the most extensive publically available archive of planktonic foraminiferal morphology and morphological variation to date.
海洋微化石记录了过去海洋的环境、生态和进化动态，这些信息被保存在时间扩展的沉积档案中。快速成像方法为利用该档案的主要优势（大量化石）提供了一种手段，用于研究进化和生态学。在这里，我们提供了第一个大规模的现代浮游有孔虫（一种主要的微化石群）的图像和 2D 和 3D 形态数据集，这些数据来自 34 个大西洋沉积物样本。提供了超过 124000 个物体的信息，包括数据集的 4/5（约 99000 个物体）的一般对象分类。在提供的约 99000 个分类中，超过 61000 个是完整或受损的浮游有孔虫。物体还包括底栖有孔虫、介形类动物、翼足类动物、骨针和浮游有孔虫的测试片段等。该数据集是一种新的高通量成像方法（AutoMorph）的第一个主要微化石输出结果，该方法旨在从化石的摄影图像中提取 2D 和 3D 数据。我们详细描述了样本制备和成像技术。这里提供的数据构成了迄今为止最广泛的公共浮游有孔虫形态和形态变异档案。
