... from the Solimões Formation. Graphic correlation indicates that the borehole spans palynological zones T13 to T16 (middle to late Miocene). We found 342 morphospecies of pollen and spores, including 280 angiosperm taxa and 62 pteridophyte taxa. Sixteen new species are described: 12 angiosperms and four...

... Amazonia) ( Cunha et al., 2007 ; Wanderley Filho et al., 2007 ). The Solimões Formation—of Miocene age ( Hoorn, 1993 , and references therein)—is restricted to western Amazonia, therefore a reactivation of the Purus Arch must have happened during this time. Causal mechanism for this reactivation...
