  ABSTRACT: The amber deposits from the Albian-Cenomanian in Myanmar have emerged as a pivotal source for exceptionally abundant fossil insect fauna since their initial discovery. Recent studies have increasingly focused on elucidating the fern inventory and examining newly available fossils from Myanmar amber, suggesting a diverse fern flora that once thrived in Cretaceous forests. Through investigations of amber collections, with particular emphasis on sporangium structures—especially the annulus types preserved in amber inclusions—this study revealed additional novelties within the Cyatheales and Schizaeales in mid-Cretaceous Myanmar amber forests. The described specimens and newly discovered fossils provide compelling evidence that Polypodiales were not only diverse and abundant but also that other fern lineages, such as Cyatheales and Schizaeales, coexisted in these ancient forest ecosystems. This study reveals the high diversity of ferns in the mid-Cretaceous Myanmar area, while also implying the paleoecological and paleogeographical significance of the Mesozoic Burmese amber forests.
