“…In these new localities, Totolapa amber is becoming more frequent among specialists interested in the study of amber inclusions (Azar et al, 2010;Durán-Ruiz et al, 2013). Totolapa is found 40 km SE of Chiapa de Corzo (Figure 1) and about 50 km SE of Tuxtla Gutiérrez, in what is geologically known as the Chiapanecan Volcanic Arc (Mora et al, 2007;. Occurrence of amber near Totolapa was formally reported based on the archaeological usage (Bryant, 1983).…”

The amber from Totolapa (Chiapas, Mexico) is thought to have been secreted by Hymenea sp. during Early to Middle Miocene time, and then reworked during Pleistocene ash flow events. Most of this amber is preserved within pyroclastic sediments. Peripheral layers of amber pieces from Totolapa yield a wealthy microflora including 1) one morpho-species of filamentous bacterium, 2) a sheathed bacterium Melanothrix mexicana gen. sp. nov., 3) five morpho-species of Actinobacteria (actinomycetes), Scopaeopsis verticillata gen. sp. nov., Thermomonosporopsis chiapasensis sp. nov., and three left in open nomenclature, and 4) diverse fungal mycelia. Melanothrix mexicana, Thermomonosporopsis chiapasensis, Actinobacteria gen. A sp. A and fungi were early colonizers of the fluid bark exudates of resin, and they grew either superficially or centripetally, as observed in modern resinicolous biota.Keywords: Amber, prokaryote, fungi, new taxon, Miocene, Mexico.

“…The central area of the ChVA is constituted of at least 10 volcanic structures, namely Navenchauc (explosion crater), Apas (collapse structure), Tzontehuitz (dome complex), and by Huitepec, Amahuitz, La Iglesia, Mispía, La Lanza, Venustiano Carranza, and Santotón (volcanic domes). Related to them appear volcanic deposits like unwedded block-and-ash-flow deposits, ash flow with accretionary lapilli, and fall deposits (Mora et al 2007). Thirteen independent Pleistocene and uppermost Pliocene lava flows were sampled in the 12 units can be described below ( Figure 2):…”

This article presents the first palaeomagnetic results from 13 independent cooling units in the Chiapanecan Volcanic Arc (ChVA). Six sites were directly dated by Ar-Ar or K-Ar methods: their dates range from 2.14 to 0.23 Ma. We isolated the characteristic palaeodirections for all 13 lavas. Eleven non-transitional directions yield a mean direction with inclination, I = 30.7 • , declination, D = 4.1 • , and precision parameters k = 63 and α 95 = 5.8 • . The corresponding mean palaeopole position is Plat = 83.3 • , Plong = 203.8 • , K = 227, A 95 = 5.
