https://mapress.com/mz/issue/feedMesozoic2025-09-30T00:00:00+13:00Diying Huangdyhuang@nigpas.ac.cnOpen Journal Systems<p><em><strong>Mesozoic</strong></em> 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/mz/article/view/mesozoic.2.3.1<strong>Aptian–Albian (Lower Cretaceous) ammonite biostratigraphy of the Miyako Group, Japan based on supplementary and revised ammonite taxa</strong>2025-02-26T20:36:22+13:00MASAKI MATSUKAWAmatsukaw@u-gakugei.ac.jpKENICHIRO SHIBATAkshibata_yokosuka-m@etude.ocn.ne.jp<p lang="en-US" align="justify"><span style="color: #000000;"><span style="font-family: Times New Roman, serif;"><span style="font-size: small;"><span style="color: #030304;">The Early Cretaceous ammonite standard zonation based on the Tethyan Realm is found in western Europe.
