49. Because without sediment, the body would wash away. • Because the sediment keeps water off the body. • Because the sediment cover keeps animals from eating the body. • Because the sediment stops the body from getting too hot. A dinosaur fossil forms only if sediment quickly covers the dinosaur’s body. Why is this so important?

50. C. Because the sediment cover keeps animals from eating the body.
