Epizoochory, Burmese amber, Rasenganus auricularus


Including zoochory, mechanisms of seed dispersal varied along with the adaptive radiation of angiosperms, but few early fossil records had been reported with specialized pericarp structure. The present study describes a new specimen from Myanmar amber, denominated Rasenganus auricularus gen. et sp. nov. In this specimen, the spirally coiled structure possibly indicates a plant origin, and an aculeate surface adapted to epizoochory.

How Our Software Was Used

Dragonfly was used to reconstruct and isolate structures of the specimen (Rasenganus auricularus), based on previously obtained image stacks.
