“Now at last we have a book that reveals in exquisite detail and admirable depth the nature of the most fascinating of ancient life: the trilobites. . . . This extraordinary group of primitive arthropods deserves wider appreciation, and I can think of no better way to find out more about them than to purchase of copy of this book, open it up, and just drink in page after page of pure trilobites.”

“Irresistible. [Levi-Setti] has given his collecting self a most precious gift. . . . A reader shares that gift, and many another, like the transient match between the giant trilobites of Newfoundland and those of the Anti-Atlas Mountains overseas, a pulse of evolutionary change while continents recede.”
