It refers to the unusual tail weapon, formed from several pairs of flat, fused bony plates (osteoderms) that made a broad, frond-like structure.

An armored dinosaur (ankylosaur) from southern Chile. It is closely related to Antarctic and Australian ankylosaurs (such as Kunbarrasaurus and Antarctopelta) and is placed in the group Parankylosauria. The stage range is approximate, since the Dorotea Formation is dated to about the late Campanian to early Maastrichtian.
