Resumo(s)
provide interesting palaeoecological and volcanological data. In the volcanic Macaronesian Islands,
these fossils are known since the 19
th
century but rarely mentioned in the literature, despite their
potential to reveal the past presence of trees and forested ecosystems. One mention to plant
moulds associated to the Anaga basalts was known, but further details were never published. Here,
we describe and illustrate for the first time lava tree moulds preserved within the Pliocene Anaga
shield volcano (4.89 to 3.95 Ma) a’a lava flow. The size and stem habit indicate that these belonged
to phanerophytes, implying the presence of a forest ecosystem during the Pliocene of Tenerife.
When compared to the palaeobotanical record of Tenerife Island, these fossils are, so far, the oldest
known published plant fossils from this island. Unfortunately, due to total combustion of the wood,
taxa identification is not possible. Despite this, the locality should be further assessed as a potential
geosite or other form of conservation for the Canary Islands’ palaeontological heritage. Further
prospection in Mio-Pleistocene Anaga shield volcano will certainly yield new palaeobotanical data
for Tenerife and the Canary Islands.
