U.S. customs officials have seized a dinosaur skull from a Wyoming home as part of a federal Homeland Security Department investigation.
The fossil came from a close relative of the Tyrannosaurus rex and is worth between $250,000 and $400,000.
The Tyrannosaurus bataar, also known as the Tarbosaurus, lived about 70 million years ago.
The Jackson Hole News and Guide reports (http://bit.ly/SqVeIW ) that federal officials have declined to provide any details about the case, saying it remains under investigation.
Federal officials recently seized a nearly complete Tarbosaurus skeleton that was sold at auction in New York and arrested a Florida man for illegally importing dinosaur fossils.
It's unclear whether there's any connection between the Jackson skull and the New York case.
