1 Which of the following is an example of a body fossil?
А
A perfect mold of a dinosaur bone
B
A carbon print left by a leaf
C
The skull of a mammoth that fell into a tar pit
D
A dinosaur footprint

The skull, because it’s an actual skull an actual part of a body, the mold is just a mold of the bone not the actual bone. A leaf print is wrong too. A Dino footprint isn’t part of a dinosoar it’s just an imprint, so the right answer is C skull
