The statuette—made of oolitic limestone tinted with red ochre pigment—is dated to circa 28,000–25,000 bce. At 4 3 / 8 inches (11.1 cm) high, it was easily transportable by hand. Both its size (portability) and the material from which it was made (not found in Willendorf) are indicators that the artifact was made elsewhere and carried to ...Clastic rocks are classified and named according to texture (clast size, sorting and rounding), and mineral composition. An important characteristic of the clastic sedimentary rocks, however, is that all have clastic textures. That is, the grains are not interlocking- they are held together as an aggregate by a cement.Limestone forms through the accumulation and compaction of marine organisms, primarily the remains of shellfish and coral, over millions of years.
