New records of Humiriaceae fossil fruits from the Oligocene and Early Miocene of the western Azuero Peninsula, Panamá

Abstract: RESUMENPara entender el origen de la diversidad de los bosques de América Central, se necesita integrar estudios de plantas actuales y fósiles. En este trabajo, describimos fósiles de Humiriaceae, excavados de dos nuevas secuencias sedimentarias en la Península de Azuero, Panamá. Los fósiles fueron encontrados en depósitos marinos-marginales del Oligoceno (una localidad) y del Mioceno temprano (dos localidades). Describimos nuevos especímenes y aumentamos la descripción morfológica de Lacunofructus cuatrecasa… Show more

“…To the south, surface sections, seismic sections, and boreholes have shown the presence of thick, middle Eocene and younger clastic sequences resting nonconformably on basement complex rocks . These clastic sedimentary sequences may have resulted from erosion of the axis of the San Blas Range, and the Azuero Peninsula (Herrera et al, 2012;Krawinkel et al, 1999;Pérez-Consuegra et al, 2018) as they shed clastic materials to the north and south, including high-quartz clastics product of the erosion of intermediate and felsic intrusives, which were at the surface from latest Eocene times (Montes et al, 2012b;Ramírez et al, 2016). Deformation along the North Panama Deformed Belt may have started in middle Miocene times resulting from incipient south-dipping underthrusting/subduction of the Caribbean Plate under the Panama Block defining a Wadati-Benioff zone (Camacho et al, 2010;Wolters, 1986).…”
