Fossil Woods from Ocu, locally known as chumicos, have been popular and highly commercialised due to their beautiful and attractive colours. Stern and Eyde (1967) published accounts on the Ocu fossil Woods for the first time. To date, taxonomic affinities on the reported taxa suggest rainforests dominated the Azuero region. These results have been confirmed in previous studies and with the first advances of this research. The fossil woods studied herein have been identified to the family level, namely, Arecaceae, Fabaceae, Moraceae and Anacardiaceae. First results confirm the dominance of rainforest taxa in Azuero.
