Nicolas Cage has agreed last week to forfeit a rare stolen dinosaur skull to U.S. authorities so it can be returned to the Mongolian government.
The office of Preet Bharara, the U.S. Attorney in Manhattan, filed a civil forfeiture complaint on Wednesday to take possession of the skull, which will be repatriated to Mongolia.
The lawsuit and a press release from Bharara's office did not specifically name Cage as the owner.
But the lawsuit described the skull as having been bought at auction from a Beverly Hills gallery, I.M. Chait, in March 2007 for $276,000 - a purchase which can be traced to Cage.
