Romaleodelphis is a genus of extinct toothed whale from the Miocene of Austria.
History and naming
[edit]The holotype skull of Romaleodelphis was discovered in 1980 in the sediments of the Ebelsberg Formation during the construction of a hydroelectric powerplant near the town of Pucking, Upper Austria. At the time, several amateur paleontologists, among them Jürgen Pollerspöck, removed fossil material from the site to prevent their destruction. The total material collected for Romaleodelphis consisted of a multitude of skull fragments that were put together by the collectors as well as several postcranial remains. Put together, the skull is mostly complete but lacks the tips of the rostrum and much of the basicranium. However, while the skull material was donated to the Staatliche Naturwissenschaftliche Sammlungen Bayerns by Pollerspöck, the postcranial material was kept by other collectors and their whereabouts are currently unknown. Despite being donated in 1992, it would take another 30 years for the skull to be described, with the paper being published by Catalina Sanchez-Posada and colleagues in 2024.[1]
The name Romaleodelphis derives from the Greek "‘romaléos" meaning sturdy or robust, in reference to the strong zygomatic process of the squamosal bone, and the -suffix "delphis". This suffix is commonly employed for the scientific names of dolphins and traces its meaning to the Greek "dophis" for womb, initially used to highlight the fact that unlike fish, dophins have a uterus. The species name on the other hand references Jürgen Pollerspöck, who discovered, saved and donated the holotype fossil.[1]
