These specimens consist mainly of leafy branches exhibiting foliar heteromorphism characteristic of upper Paleozoic coniferophytes from Gondwana. This group includes <i>Genoites</i> sp. with lax arranged ovules on the last order branches, Krauselcladus sp. represented by a small vegetative branch with biand trifurcated leaves, and <i>Buriadia</i> cf. <i>Buriadia heterophylla</i> Seward et Sahni emend. Serbet, Escapa, Taylor, Taylor et Cúneo, 2010, showed axes with multifid leaves and ovules on terminal branches. Vegetative fragments with small lanceolate leaves are assigned to <i>Ferugliocladus</i> cf. <i>F. riojanum</i> Archangelsky et Cúneo, 1987. In addition, an isolated, probably male reproductive structure similar to those known for th latter species was identified. The presence of <i>Buriadia</i> is recognized for the first time in the Carboniferous-Permian of Argentina, as well as the identification of vegetative buds or shoots, a previously undocumented characteristic for this Paleozoic coniferophyte from Gondwana.</div> <a class="anchor" id="funding"></a> <div class="abstractLabel">FUNDING</div> <div class="abstractContentReal">This research was supported by PROICO 03-0218 (Dr. Jorge Chiesa) and PICT 2020-1294 (Dr. Silvia Césari).</div> <a class="anchor" id="conflictOfInterests"></a> <div class="abstractLabel">CONFLICT OF INTEREST</div> <div class="abstractContentReal">The authors have declared that no competing interests exist.</div> <div style="height: 20px;line-height: 20px;font-size: 0;"> </div><a class="anchor" id="references"></a> <div class="abstractLabel"><span class="block">REFERENCES</span><span class="block"> </span><span class="block">(45)</span></div> <div class="abstractContent"> <a class="anchor" id="1"></a> <div class="ref" id="ref_1"> <div class="dirLeft refNo">1.</div> <div class="dirLeft refText"> <div style="word-break: break-word;">Archangelsky, S., 1978.
