Abstract

The dodo Raphus cucullatus Linnaeus, 1758, an extinct and flightless, giant pigeon endemic to Mauritius, has
fascinated people since its discovery, yet has remained surprisingly poorly known. Until the mid-19th century, almost all that
was known about the dodo was based on illustrations and written accounts by 17th century mariners, often of questionable
accuracy. Furthermore, only a few fragmentary remains of dodos collected prior to the bird’s extinction exist. Our
understanding of the dodo’s anatomy was substantially enhanced by the discovery in 1865 of subfossil bones in a marsh called
the Mare aux Songes, situated in southeastern Mauritius. However, no contextual information was recorded during early
excavation efforts, and the majority of excavated material comprised larger dodo bones, almost all of which were
unassociated. Here we present a modern interdisciplinary analysis of the Mare aux Songes, a 4200-year-old multitaxic
vertebrate concentration Lagerst€atte. Our analysis of the deposits at this site provides the first detailed overview of the
ecosystem inhabited by the dodo. The interplay of climatic and geological conditions led to the exceptional preservation of
the animal and associated plant remains at the Mare aux Songes and provides a window into the past ecosystem of Mauritius.
This interdisciplinary research approach provides an ecological framework for the dodo, complementing insights on its
anatomy derived from the only associated dodo skeletons known, both of which were collected by Etienne Thirioux and are
the primary subject of this memoir.
