UN NUEVO GÉNERO DE LICOFITA DE LA FORMACIÓN BAJO DE VELIZ (PALEOZOICO SUPERIOR) PROVINCIA DE SAN LUIS, ARGENTINA
AbstractSpecimens of a new Iycopod were collected in the Pallero Member of the late Carboniferous- early Permian Bajo de Véliz Fonnation at the Bajo de Véliz locality (San Luis province). They are undecorticated stems differentiated into sterile and fertile zones, and densely covered by helically disposed microphyles that produced false scars after shedding. Strobilar structures teminally attached to the stems have also been found. Based on these morphological features a possible relationship of this southem Iycopod to the northern family Chaloneriaceae is suggested. This new finding enlarges our knowledge on Gondwana Iycopods, a group scarcely represented in the southern hemisphere.
