meteoroid material in the rock layers that formed around the time of the extinction What would be an example of additional
, empirical evidence to support the extinction hypothesis?
A finding fossils that had been crushed
B. O finding fossils of early mammals with the dinosaur fossils
C. finding a large crater that dates from the time of the dinosaur extinction
D. finding dinosaur fossils in rock layers younger than the layer with the meteoroid material
