A liana from the lower Miocene of Panama and the fossil record of Connaraceae

Abstract: The discovery of this stem confirms the presence of Connaraceae in the Neotropics by the early Miocene, provides the oldest evidence of the climbing habit in the family, and contributes to our understanding of the flora of Panama 19 mya. Although the fossil record of Connaraceae is sparse, reliable occurrences span three continents and indicate that the family originated as early as the Late Cretaceous-Paleocene and was widespread by the early Miocene.

“…Silicified wood occurs in Oligocene and Miocene at several locations in Panama. This material has been described in detail by several research teams [12][13][14][15][16][17][18]. Panama fossil wood has been recognized as an important indicator for understanding the interchange of plant taxa between North and South America, and for interpreting the effects of tectonic change on plant communities.…”

“…Plant macrofossils (e.g., fruits, leaves, and wood) in Central America are necessary to better understand the dispersal and evolution of particular plant groups. In recent years, excavations along the Panamá Canal, Lake Alalajuela and Azuero Peninsula have allowed the discovery of various Cenozoic localities with abundant fruits, seeds, leaves, and wood from several families; for exam-ple Humiriaceae, Juglandaceae, Malvaceae, Calophyllaceae, Connaraceae and Chrysobalanacea (Herrera et al, 2010(Herrera et al, , 2014a(Herrera et al, , 2014bCarvalho et al, 2013;Rodríguez-Reyes et al, 2014Jud et al, 2016;Jud and Nelson, 2017;MacFadden et al, 2017;Nelson and Jud, 2017). We report new permineralized and carbonized fossil endocarps and seeds of Humiriaceae from three new localities on the Pacific coast of Panamá, near the town of Torio, province of Veraguas (Figure 1).…”

“…Esta relación entre el diámetro del tallo y el calibre de los vasos fue aplicado a la reconstrucción a través de una método estadístico de regresión logística (Jud et al, 2017(Jud et al, , 2021. Este método clasificó los ejes fósiles como trepadores o autosoportados con base en el diámetro máximo del vaso y el diámetro del cilindro leñoso central.…”

“…Este método clasificó los ejes fósiles como trepadores o autosoportados con base en el diámetro máximo del vaso y el diámetro del cilindro leñoso central. El modelo se calibró utilizando un conjunto de datos de 71 muestras obtenidas de Ewers et al (1990), y reconstruyó el hábito de 22 ejes fósiles con cilindros leñosos de más de 5 mm de diámetro del Mioceno de Panamá, entre ellos Rourea blatta Jud et Nelson (Connaraceae) (Jud & Nelson, 2017) y Ampelorhiza heteroxylon (Sapindaceae) (Jud et al, 2021).…”
