Portugal is full of surprises, the discovery of a unknown trilobite being the latest, as researchers at the University of Tras-os-Montes and Alto Douro confirm that an unprepossessing sample sent in for analysis is the oldest record of its type.
Aptly describing the discovery as 'historic,' the 455 million-year-old trilobite fossil was found in the Cabeço do Peão rock formation in the Macão municipality, Santarém.
