“…It should be noted that specimens of Samaropsis sp. 1, with similar morphology to S. gigas, also described by Souza and Iannuzzi (2007) for the same deposits, have in its structure preserved marks of the action of sucking insects, supporting the theory of the protection of the nucellus suggested by Tiffney (2004). This possibility, however, must be better investigated in future studies that certify the evidence of insect-plant interactions in these seeds.…”

“…On the other hand, regarding the dispersal structures, S. gigas has two important features: the presence of an inner and fibrous testa involving the nucellus, called "endotesta" by Souza and Iannuzzi (2007), which is preserved in all specimens ( Figure 2B), and a well-developed external layer "sarcotesta".…”

The morphological analysis of seeds has been an important subject in modern ecological studies, once it provides evidence about the biology and adaptations of the parent plant. However, this kind of study has been restricted to the ecology of modern plants and is rarely used in interpretations of Paleozoic data. From the understanding of dispersal syndromes analysis as an important tool to paleoecological reconstruction, this study provides a first approach using this tool with seeds from the Lower Permian strata of southern Paraná Basin in Rio Grande do Sul. Based on previously classified seeds and using their biological and taphonomic data, the syndrome of dispersal was interpreted, and their placement in successional groups (pioneer, early-successional and later-successional) was suggested. Seven morphospecies were analyzed: Samaropsis gigas, representing a later-successional species living in water bodies with hydrochory as its dispersal syndrome; Samaropsis kurtzii, typical of early-successional species showing anemochory as its dispersal syndrome and living in distal areas in relation to water bodies; Samaropsis aff. S. millaniana, Cordaicarpus aff. C. brasilianus, Cordaicarpus cerronegrensis and Cordaicarpus truncata have typical characteristics of pioneer plants, exhibiting barochory as their primary dispersal syndrome with other syndromes associated.

“…The locality belongs stratigraphically to the uppermost Itararé Group (Taciba Formation) that occurs in the Paraná Basin (Souza and Iannuzzi 2009;Pinheiro et al 2012a), and represents lacustrine deposits from a major transgressive-regressive cycle named by Milani et al (1998) as the Gondwana I Supersequence. The Morro do Papaléo locality is lower Permian (Souza and Iannuzzi 2009). …”

The genus Botrychiopsis consists of leaves with substantial heteromorphism, present in late Paleozoic Gondwanan floras. The genus is recorded in paleofloras from Australia, India, South Africa, Brazil, and Argentina, and occurs from the latest Mississippian to the early Permian. Here, we report and analyze the first record of plant-insect interactions found in the Botrychiopsis-type leaves from the basinal deposits of Permian Argentina and Brazil. The samples are from three different Permian deposits: Arroyo Totoral, Bajo de Véliz (Argentina), and Morro do Papaléo (Brazil). Evidence of insect-plant interactions was present in only eight of 154 specimens analyzed. We found evidence of margin and hole feeding damage made by insects. This represents the first evidence of plant-insect interactions in Botrychiopsis leaves from Permian Gondwanan deposits. The occurrence of herbivory only on the Permian species B. plantiana may indicate that consumption of these leaves began during this interval, not in the Carboniferous, as occurred with Cordaites leaves.
