It is an international peer-reviewed scientific journal, which publishes high quality, original research contributions as well as review papers. Papers are published in English and they cover a wide spectrum of topics in palaeoentomology, fossil terrestrial arthropods and amber research, i.e. systematic palaeontology, morphology, diversity, palaeogeography, palaeoecology, palaeobehavior, evolutionary and phylogenetic studies on fossil insects and terrestrial arthropods, biostratigraphy, taphonomy, and amber (deposits, inclusions, geochemistry, curation). Descriptions of new methods (analytical, instrumental or numerical) should be relevant to the broad scope of the journal.</p> https://mapress.com/pe/article/view/palaeoentomology.5.1.1 <p><strong>Discovery of coprolites in an Early Permian fern mesophyll</strong></p> 2021-11-08T16:34:06+13:00 WEI-MING ZHOU wmzhou@nigpas.ac.cn MING-LI WAN mlwan@nigpas.ac.cn JOSEF PŠENIČKA jpsenicka@zcm.cz JUN WANG jun.wang@nigpas.ac.cn <p>Plants and arthropods interact with each other and constitute an important part of the modern terrestrial ecosystem (Schoonhoven <em>et al</em>., 2005). Historically, fossil records of plant-arthropod interactions have been well documented in Paleozoic terrestrial ecosystems, which were evidenced by large coprolites containing various plant fragments (<em>e</em>.<em>g</em>., Salter <em>et al</em>., 2012), small larvae and coprolites remained in plant organs (<em>e</em>.<em>g</em>., Feng <em>et al</em>., 2017), and diverse functional feeding groups discovered on plant stems, rachises, roots, leaves and fertile organs (<em>e.g</em>., Liu <em>et al</em>., 2020).</p> 2022-01-05T00:00:00+13:00 Copyright (c) 2021 Magnolia press limited https://mapress.com/pe/article/view/palaeoentomology.5.1.2 <p><strong>Termite coprolites (Blattodea: Isoptera) from the Early Cretaceous of eastern Inner Mongolia, Northeast China</strong></p> 2021-11-16T16:55:41+13:00 CHONG DONG cdong@nigpas.ac.cn GONG-LE SHI glshi@nigpas.ac.cn ZI-XI WANG zxwang@nigpas.ac.cn DI-YING HUANG dyhuang@nigpas.ac.cn <p>Well-preserved coprolites (fossil faecal pellets) were found from lignite seams of the Lower Cretaceous Huolinhe Formation at the Huolinhe Basin in eastern Inner Mongolia, Northeast China. These coprolites provide a combination of following features: oval to cylindrical shaped with six longitudinal ridges, hexagonal to elliptical cross-sections, and one blunt end and the other pointed end. According to these distinct features and their size range, the producers of these coprolites are attributed to termites. Termites were estimated to have originated in the earliest Cretaceous with an evolutionary radiation in the Early Cretaceous. The presence of wood debris in the coprolites indicate that the Early Cretaceous termites from the Huolinhe Basin had wood-feeding habits; and anatomical features displaying on the wood debris further suggest their feeding preference was coniferous wood. Besides, the results of a <em>k</em>-means clustering analysis performed for these coprolites indicate that three clusters with different proportion were present, suggesting the division of labor in termites’ sociality existed as early as the Early Cretaceous.</p> 2022-01-05T00:00:00+13:00 Copyright (c) 2021 Magnolia press limited
