“…The humidity of the climate oscillated, with monsoonal systems established by the end of the interval (Preto et al, 2010), particularly after the Carnian Pluvial Event (CPE; ~233 Ma), which was a major period of biological turnover associated with exceptional global rainfall (Dal Corso et al, 2020; Dal Corso, Mills, et al, 2022; Simms & Ruffell, 2018). Distinct changes in the land flora occurred during the Triassic, with dominance and increasing diversification of seed plants (Atkinson et al, 2018; Grauvogel‐Stamm & Ash, 2005). Along with Cycadales, Bennettitales, seed ferns and other groups, the conifers experienced considerable morphological radiation, with the origin of seven modern families by the end of the period, including, for example, Pinaceae, Taxaceae and Araucariaceae (Willis & McElwain, 2014).…”

Recent progress in beetle palaeontology has incited us to re‐address the evolutionary history of the group. The Permian †Tshekardocoleidae had elytra that covered the posterior body in a loose tent‐like manner. The formation of elytral epipleura and a tight fit of elytra and abdomen were important evolutionary transformations in the Middle Permian, resulting in a tightly enclosed subelytral space. Permian families were likely associated with dead wood of gymnospermous trees. The end‐Permian extinction event resulted in a turnover in the composition of beetle faunas, especially a decline of large‐bodied wood‐associated forms. Adephaga and Myxophaga underwent a first wave of diversification in the Triassic. Polyphaga are very rare in this period. The first wave of diversification of this suborder occurs in the Jurassic, with fossils of Elateriformia, Staphyliniformia and Cucujiformia. The Cretaceous fossil record has been tremendously enriched by the discovery of amber inclusions. Numerous fossils represent all major polyphagan lineages and also the remaining suborders. Improved analytical methods for documenting and placing extinct taxa are discussed. Different factors have played a role in the diversification of beetles. The enormous number of species associated with flowering plants, and timing and patterns of diversification in phytophagous lineages indicate that the angiosperm radiation played a major role in beetle macroevolution. Moreover, the evolution of intimate partnerships with symbionts and the acquisition of novel genes—obtained from fungi and bacteria via horizontal gene transfers—facilitated the use of plant material as a food source and were key innovations in the diversification of plant‐feeding beetles.

“…Cycads reached the peak of their ecological and taxonomic diversity during the Jurassic (e.g., Coiro & Pott, 2017). Conifers became a dominant group of land plants and most modern groups appeared by the end of the Jurassic (Atkinson et al, 2018; Leslie et al, 2018; see also Beutel & Yavorskaya, 2024).…”

“…e shape and size of the pollen cones resemble those of Classostrobus, the male cone of Jurassic-Cretaceous Cheirolepidiaceae, but the arrangement of the pollen sacs on the microsporophyll corresponds more closely with that of Voltziales. It seems that this family did not continue to evolve further within conifers but turned out to be important in evolutionary considerations (Atkinson et al, 2018;Leslie et al, 2018) and in research on pollen preserved in situ (for references see Pacyna et al, 2017;Zhang et al, 2021). is is the first and so far the only detailed documented fossil coniferous plant in Polish paleobotany.…”

Research on Polish Mesozoic macroflora has remarkably changed over the last 100 years. Compared with traditional nineteenth-century taxonomical and evolutionary studies, modern research also investigates of fossil plant diversity, plant interactions with the environment and animals, and deep changes in vegetation influenced by environmental and climate change. In this review, we present the most important turning points in Polish Mesozoic macroflora research and the development of cognitive techniques by discussing selected studies carried out by Polish palaeobotanists.
