Uncovering the skull of a Ceratopsian dinosaur in Grand Staircase National Monument in Southern Utah proved to be the easy part. Moving the find from its site is proving to be the true challenge. The 70-million year old skull won't budge when they tried to lift the fossil out with a helicopter.

Paleontologists grappling with this weighty issue are taking it philosophically. "This is paleontology. A lot of waiting. A lot of things can go wrong, and it just too heavy."

Ceratopsia ("horned faces") is a group of plant-eating dinosaurs that lived in present-day North America and Asia during the Cretaceous Period. The most famous member of the family is perhaps the Triceratops.
