From the reviews: "Volume 1 begins with a review of the most recent paleontological and geological investigations in the Laetoli area, including a reassessment of the best-known fossil localities; it then sorts through the geology of the region. ... should be in any library with natural history collections. ... provide a critical resource for human evolution studies, and will appeal to geologists, paleontologists, and anthropologists alike. Summing Up: Highly recommended. Academic and professional audiences, all levels." (M. A. Wilson, Choice, Vol. 48 (11), July, 2011) "Harrison has compiled a large number of generally impressive reports stemming from this renewed work at Laetoli into a handsome two-volume set. ... Volume 1 comprises 19 chapters devoted largely to geology, geochronology, paleoecology, and paleoenvironmental reconstruction. ... Harrison is to be congratulated for having assembled an extraordinary team of research collaborators to investigate (or reinvestigate) it to its full extent. ... It will be an indispensible resource for students of African Neogene paleontology, geology, and (especially) paleoanthropology." (Frederick E. Grine, The Quarterly Review of Biology, Vol. 87, March, 2012)
