A federal Homeland Security Department official says a dinosaur skull seized from a Wyoming home is related to an investigation into fossil smuggling from Mongolia.
Louis Martinez of U.S. Immigration and Customs Enforcement's Homeland Security Investigations says he can't release any more detail because the investigation is ongoing.
The fossil seized in Wyoming came from a close relative of the Tyrannosaurus rex and is worth between $250,000 and $400,000.
The Tarbosaurus lived about 70 million years ago.
Federal officials recently seized a nearly complete Tarbosaurus skeleton that was sold at auction and arrested a Florida man for illegally importing dinosaur fossils.
A U.S. attorney for the president of Mongolia says that country welcomes the increased awareness for the illegal trade of Mongolian fossils.
