Reward over dinosaur fossil damage
Rangers are searching for leads after someone damaged a fossil at Dinosaur National Monument in the US.
The National Park Service says a ranger leading a guided tour discovered damage to the fossilised humerus bone of a sauropod dinosaur and removal of part of the bone.
The fossil is among those located along the 1.2-mile Fossil Discovery Trail that runs between the Quarry Visitor Centre and the Quarry Exhibit Hall, where a famous wall of about 1,500 dinosaur bones is located.
All fossils in the monument, along the Utah-Colorado line, are protected and may not be collected.
A 750 dollar (£460) reward is being offered for information leading to a conviction in the case.
