“…A large number of reports on the biological inclusions have been published over the last sixty years (Wille, 1959;Wygodzinsky, 1959;Hurd et al, 1962;Petrunkevitch et al, 1963, among others) with an increment on the scientific interest in this amber over the last ten years (Engel, 2004;Castañeda-Posadas and Cevallos-Ferriz, 2007;Sol orzano-Kraemer, 2007García-Villafuerte, 2009;Calvillo-Canadell et al, 2010;Vr sanský et al, 2011;Coty et al, 2014;Riquelme et al, 2014a, among many others). Most of the publications deal with systematic descriptions of the organisms, but the molecular chemistry of the amber has also been examined (Riquelme et al, 2014b).…”

“…Speciation of the sulfur atom using synchrotron radiation has been the focus of several XANES studies. [22][23][24][25][26][27][28][29][30][31][32][33] Using the XANES technique, it is possible to perform the sulfur chemical speciation in different plant tissues through the identification and quantification of the sulfur functional groups. [34][35][36][37][38][39][40][41][42][43] XANES measurements were performed at the SXS beamline of the LNLS.…”

The inorganic composition of the bark and leaf of a plant from the Amazon rainforest, Andira surinamensis, was determined using two non-destructive, multi-element techniques: X-ray fluorescence (XRF) and Rutherford backscattering spectrometry (RBS). XRF measurements were made using both a conventional X-ray source and synchrotron radiation. It was observed that although magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, and potassium are present in higher concentrations in the leaf, calcium is about three times more concentrated in the bark. Manganese, iron, copper, zinc, strontium and barium were also detected, with barium showing a concentration above the minimum toxicity level for plants. Chemical speciation of sulfur, performed using the X-ray absorption near edge structure (XANES) technique, showed that sulfur is present in several oxidation states, with a much larger contribution from the inorganic sulfate in the leaves. The article evidences that the combined use of synchrotron radiation and non-destructive multielement techniques allows for an efficient and accurate determination of the inorganic composition and chemical speciation in plants.

“…Las inclusiones de ámbar proceden de estratos de lutita carbonosa intercalados con los de las Formaciones Mazantic (esquisto) y Balumtum (arenisca) y tienen una edad estimada para el Mioceno Temprano-Medio, determinada a partir de la presencia de moluscos de los géneros Turbinella Lamarck, 1799 y Melongena Schumacher, 1817, incluidos en el ámbar (Vega, Nyborg, Coutiño, Solé & Hernández-Monzón, 2009;Perrilliat, Vega & Coutiño, 2010). Los depósitos de Simojovel de Allende están asociados a un ambiente de línea de costa y a tierras bajas continentales (Perrilliat, Vega & Coutiño, 2010;Riquelme et al, 2014).…”

En el presente trabajo se muestran resultados de la identificación de cinco fósiles vegetales incluidos en ámbar de Simojovel, Chiapas. Las estructuras estudiadas corresponden a dos flores pertenecientes a la Familia Arecaceae; a dos hojas compuestas (foliolos) pertenecientes a la Familia Fabaceae y una hoja aislada perteneciente a la Familia Myrtaceae. La identificación y descripción de este tipo de estructuras fortalece el registro existente de la distribución de esas familias vegetales para el Mioceno en Chiapas. Este estudio contribuye a ampliar el conocimiento de la diversidad de restos vegetales incluidos en el ámbar de Chiapas.
