Did animals die before Adam sinned?

Animals preserved as fossils (often assumed to be millions of years old) suffered from cancer, arthritis, tooth decay, bone infection, vertebra fusion, parasitic infections, abnormal teeth, tumours, bite wounds, fractured bones, ossified tendons, avascular necrosis (death of bone tissue due to a lack of blood supply). Could God have described all this as "very good" about 6000 years ago?
