“…Arthropod damage to Sphenobaiera leaves has been reported from various other regions and ages (e.g. Steinthorsdottir et al, 2015;Na et al, 2017;Lin et al, 2019). However, none of the illustrated herbivory or oviposition features match those on the Leigh Creek S. insecta leaves.…”

Upper Triassic deposits of the Leigh Creek Coal Measures in South Australia yield exquisitely preserved plant fossils of a typical mid-to high-latitude Gondwanan flora. Here, we present a detailed cuticular analysis of the ginkgoalean leaf Sphenobaiera insecta J.M. Anderson et H.M. Anderson nov. emend., which is characterized by an unlobed or once-lobed, elliptic to oblanceolate lamina, abundant round to fusiform resin bodies, and absence of interveinal striae. We also propose an emendation to the genus diagnosis so that Sphenobaiera encompasses also unlobed leaves such as most of those attributed to S. insecta. Such leaves may be distinguished from morphologically similar co-occurring leaf taxa, such as Heidiphyllum elongatum (Pinales) and Rochipteris spp. (Petriellales), based on the characteristic resin bodies and sporadic occurrence of vein dichotomies in the central lamina. Sphenobaiera insecta leaves show common evidence of a particular type of herbivory damage along the leaf margin in the form of small (1-1.5-mm-long) semi-circular patches each lined by a crescent-shaped, darkened reaction rim.

“…Mesozoic gymnosperm-and fern-dominated plant assemblages typically are characterized by sporadic arthropod and pathogen associations from collections currently of less than 700 specimens that likely represent an inadequate number of samples. Major assemblages (62) include the Middle Triassic of northeastern Italy (71,118); the Middle to Upper Triassic of the Paraná Basin of Brazil (17) and Cuyana Basin of Argentina (79); the Upper Triassic of Arizona, United States (65) and Antarctica (13); and the Middle-Late Jurassic boundary of northeastern China (31,80,90,114). While these assemblages represent a limited number of specimens for definitive conclusions based on quantitative data (101,102), there are two assemblages for which considerable data exist about the composition and structure of arthropod associations of Mesozoic plant communities where gymnosperms are dominant and ferns subdominant-the Late Triassic Aasvoëlberg 411 plant assemblage from the regional Molteno Flora of South Africa (65,67) and the Early Cretaceous Dawangzhangzi plant assemblage of the regional Jehol Flora of northeastern China (31,80,130).…”

The use of the functional feeding group–damage type system for analyzing arthropod and pathogen interactions with plants has transformed our understanding of herbivory in fossil plant assemblages by providing data, analyses, and interpretation of the local, regional, and global patterns of a 420-Myr history. The early fossil record can be used to answer major questions about the oldest evidence for herbivory, the early emergence of herbivore associations on land plants, and later expansion on seed plants. The subsequent effects of the Permian–Triassic ecological crisis on herbivore diversity, the resulting formation of biologically diverse herbivore communities on gymnosperms, and major shifts in herbivory ensuing from initial angiosperm diversification are additional issues that need to be addressed. Studies ofherbivory resulting from more recent transient spikes and longer-term climate trends provide important data that are applied to current global change and include herbivore community responses to latitude, altitude, and habitat. Ongoing paleoecological themes remaining to be addressed include the antiquity of modern interactions, differential herbivory between ferns and angiosperms, and origins of modern tropical forests. The expansion of databases that include a multitude of specimens; improvements in sampling strategies; development of new analytical methods; and, importantly, the ability to address conceptually stimulating ecological and evolutionary questions have provided new impetus in this rapidly advancing field.

“…The end-Triassic extinction event exemplifies the potential utility of statistical methods with the capacity to generate null expectations and disentangle the various potential causes of fluctuations in herbivory. Few latest Triassic floras have been examined for insect herbivory (Ghosh et al, 2015) and, of the geologic periods that contain more than five described insect fossils, the Jurassic is the least studied in this context (McLoughlin et al, 2015;Ding et al, 2015;Pinheiro et al, 2016;Na et al, 2018;Santos et al, 2021).…”
