Scroll down to see and read the whole story. Before the dig, we had the opportunity to look around one of the back rooms in the museum. This room was full of shelves and shelves of dinosaur bones that had been carefully prepared by the paleontologists. Some would become displays in the museum. Some would be used to make casts for display in museums.
Casts work much better for display because they are much lighter than the fossilized bones.
This is a Triceratops skull on the right and the cast that was made from it on the left. Mrs. Bamdad loved seeing this because Triceratops is one of her favorite dinosaurs. Then it was time to go to the dig site. That is because it is easiest there to see dinosaur bones sticking out of rocks as they erode away. Paleontologists usually only dig in areas where they know they will find bones.
