Fossils records provide evidence about the history of life on Earth including how organisms have changed over time. It tells about the structures of ancient organisms, their environment, and the way they lived. However, fossils can not usually provide information about soft tissues of an organism because soft tissues rarely become fossilized. Additionally, fossils rarely provide information about interactions among organisms and therefore tell us little about animal behavior.
D = m/V
m = 75g
V = 4 x 4 x 4 = 64 cm^3
d = 75/64 = 1 11/64 g/cm^3
