'.the volume contains original and stimulating contributions to quantitative biostratigraphy and lithostratigraphy by four authors who are foremost in this branch of science and have pioneered its application. I agree with this assessment; the book is clearly the place to start for those interested in becoming conversant with modern techniques of stratigraphy analysis.'
