Non-pollen palynomorphs (NPPs) form a large group of biological objects found in palynological slides besides pollen grains. This includes various remains of algae and fungi, shells, resting stages and eggs of invertebrates, among others. Publications of NPP-types started in the 1970s with studies of BvG and colleagues, and large numbers of new types continue to be published every year. For an overview of this diverse world of “extra fossils”, we created the Non-Pollen Palynomorph Image Database (NPP-ID) to gather NPP knowledge, structured by acronyms and known taxonomy to assist identification and palaeoecological interpretation (https://nonpollenpalynomorphs.tsu.ru/). An integral part is a database of illustrations, descriptions and ecological background of NPPs. While numerical data are routinely stored in open access repositories, the NPP-ID enables the definitions, identification and interpretation of the NPP taxa to be shared. The NPP-ID operates as an open research project aiming to provide open access to descriptions and illustrations of NPPs. However, due to publication rights, access to some original images is restricted and registration by users is required. We encourage palynologists to contribute to the further growth of the database by uploading their own microphotographs or drawings under an open access license. Contributors will be acknowledged by co-authorship in publications on updates of the NPP-ID.

非花粉孢粉体 (NPP) 形成了除花粉粒外在孢粉学载玻片中发现的一大群生物对象。这包括藻类和真菌的各种遗骸、贝壳、静止阶段和无脊椎动物的卵等。NPP 类型的出版物始于 1970 年代对 BvG 及其同事的研究，并且每年都会继续发表大量新类型。为了概述这个“额外化石”的多样化世界，我们创建了非花粉孢粉形图像数据库 (NPP-ID) 来收集 NPP 知识，由首字母缩略词和已知分类法构成，以帮助识别和古生态解释（https://nonpollenpalynomorphs .tsu.ru/）。一个不可或缺的部分是核电厂的插图、描述和生态背景数据库。虽然数字数据通常存储在开放访问存储库中，NPP-ID 可以共享 NPP 分类群的定义、识别和解释。NPP-ID 作为一个开放的研究项目运作，旨在提供对 NPP 的描述和插图的开放访问。但是，由于出版权，某些原始图像的访问受到限制，需要用户注册。我们鼓励孢粉学家在开放获取许可下上传他们自己的显微照片或图纸，为数据库的进一步发展做出贡献。贡献者将在 NPP-ID 更新的出版物中以共同作者身份得到承认。某些原始图像的访问受到限制，需要用户注册。我们鼓励孢粉学家在开放获取许可下上传他们自己的显微照片或图纸，为数据库的进一步发展做出贡献。贡献者将在 NPP-ID 更新的出版物中以共同作者身份得到承认。某些原始图像的访问受到限制，需要用户注册。我们鼓励孢粉学家在开放获取许可下上传他们自己的显微照片或图纸，为数据库的进一步发展做出贡献。贡献者将在 NPP-ID 更新的出版物中以共同作者身份得到承认。
