AB Plant fossils are known from the Azores Islands, yet poorly studied. We present a comprehensivebibliographical review for the archipelago. A first pre-scientific reference dates from late fifteenth century,while the first scientific description was reported in 1821, accounting for trunks in pyroclastic units andsilicified plants within hydrothermal deposits. Throughout the second-half of the nineteenth century andthe first-half of the twentieth century, prospection by naturalists and geological mapping work, led tothe discovery and description of plant fossils in most islands. From the 1970s onwards, the taxonomicinterest ceased, and plant fossils were used mainly for 14C dating. Recently, sediment cores from lakesand peatlands were used for palaeoecological reconstructions and to measure anthropogenic impacts.Generally, plant fossils are younger than 50 ka, although older fossils may exist. Azorean plant fossilsinclude somatofossils of leaves, stems, logs and seeds preserved as impressions, compressions, adpressions,permineralizations, lava tree casts and mummifications. The taphonomy of macrofloral elements is usuallyrelated to explosive volcanic activity, while palynological record is associated with lake sediments andpeat bogs. The persistence in palaeobotanical and palaeopalynological studies will decisively contributeto disentangle the paleodiversity, palaeoecology, and add crucial information on insular plant phylogenyand biogeography
