NEW RECORD OF ZOLLERNIOXYLON TINOCOI MUSSA (FABACEAE) IN JURUÁ VALLEY, SOLIMÕES FORMATION (MIOCENE), ACRE BASIN, BRAZIL. A new record of fossil wood to the Valley of Juruá, Solimões Formation, Southwestern Amazon, is analyzed. The fossil material came from one of the countless outcrops found along the Juruá River. The wood described presents anatomical affi nities with the Fabaceae and more specifi cally with Zollernioxylon tinocoi Mussa. This new record confi rms the presence of the Fabaceae in the past vegetation of Amazon and by its comparison with modern vegetation contributes to the paleoenvironmental reconstructions of the region.
