The Trilobite Collector’s Guide Hardcover – January 23, 2024
by Andy Secher (Author), Richard Fortey (Foreword), Melanie J. Hopkins (Foreword)
For more than 250 million years, the primeval oceans of the Paleozoic teemed with trilobites. These hardy invertebrates evolved into an astonishing array of separate species―more than 25,000 at last count―and much remains unknown about these once-ubiquitous creatures. Fossil enthusiasts are captivated by trilobites’ diversity and adaptability, enthralled by the possibility of catching a glimpse of a transcendently strange past.
Andy Secher―one of the most prolific trilobite collectors in the world―takes readers on an entertaining and enlightening journey to the distant epoch when these ancient arthropods swarmed through the seas. The Trilobite Collector’s Guide presents a series of “Top Ten” lists covering everything from celebrated Cambrian localities and world-class fossil shows to invaluable collecting tips and ways to spot a fake trilobite. These brisk and often witty chapters enumerate trilobites in all their beauty and strangeness, from the most common to the ridiculously rare, the outrageously old to the last in line. The Trilobite Collector’s Guide showcases more than 350 full-color photographs, mostly of stunning specimens from Secher’s personal collection, that put trilobites’ staggering variety and complexity on full display. Engaging and informative, this book lets readers see the world of trilobites as it’s never been seen before.

Travels with Trilobites: Adventures in the Paleozoic Hardcover – June 21, 2022
by Andy Secher (Author)
Trilobites were some of the most successful and versatile organisms ever to exist. Among the earliest forms of complex animal life, these hard-shelled marine invertebrates inhabited the primal seas of the Paleozoic Era. Their march through evolutionary time began in the Lower Cambrian, some 521 million years ago, and lasted until their demise at the end of the Permian, more than 250 million years later. During this vast stretch of planetary history, these adaptable animals filled virtually every available undersea niche, evolving into more than 25,000 scientifically recognized species.
In Travels with Trilobites, Andy Secher invites readers to come along in search of the fossilized remains of these ancient arthropods. He explores breathtaking paleontological hot spots around the world―including Alnif, Morocco, on the edge of the Sahara Desert; the Sakha Republic, deep in the Siberian wilderness; and Kangaroo Island, off the coast of South Australia―and offers a behind-the-scenes look at museums, fossil shows, and life on the collectors’ circuit. The book features hundreds of photographs of unique specimens drawn from Secher’s private collection, showcasing stunning fossil finds that highlight the diversity, complexity, and beauty of trilobites. Entertaining and informative, Travels with Trilobites combines key scientific information about these captivating creatures with wry, colorful observations and inside stories from one of the world’s most prolific collectors.

Trilobites of New York: An Illustrated Guide Hardcover – May 15, 2002
by Thomas E. Whiteley (Author), Gerald J. Kloc (Author), Carlton E. Brett (Author), Rolf Ludvigsen (Foreword)
“Trilobites are the most lifelike of fossils―many well-preserved specimens belie their great antiquity and seem almost ready to arch their bodies, peer about with their compound eyes, and crawl forward as if to complete a journey that was interrupted hundreds of millions of years ago.”―from the Foreword
“New York State is and has long been a magnet for trilobite hunters…. New York’s trilobites were among the first illustrated fossils in North America…. Many outstanding localities in New York State, from the majestic Ordovician limestone bluffs of Trenton Falls, to the Silurian beds in the great gorge of Niagara River, to the Devonian shale cliffs of Lake Erie, continue to yield abundant and spectacular trilobite fossils. New York strata have also yielded more trilobites with preserved appendages and other “soft parts” than almost any other region of the world…. Spectacular, ornate trilobites from New York ranging from a few millimeters to nearly a half meter in length, are featured in museums all over the world.”―from the Preface
This superbly illustrated book reviews the trilobite fossils found throughout New York State, including their biology, methods of taphonomy (preservation of specimens), and the broader Paleozoic geology of the state. A general chapter on the geology of New York State places the importance of these now-extinct invertebrate marine animals into context. Sixty-seven line drawings and 175 black-and-white photographs illustrate individual species, many represented here by type specimens, and display the eerie beauty that has made New York State trilobites favorites of collectors the world over.

Trilobite: Eyewitness to Evolution Paperback – November 13, 2001
by Richard Fortey (Author)
With Trilobite, Richard Fortey, paleontologist and author of the acclaimed Life, offers a marvelously written, smart and compelling, accessible and witty scientific narrative of the most ubiquitous of fossil creatures.
Trilobites were shelled animals that lived in the oceans over five hundred million years ago. As bewilderingly diverse then as the beetle is today, they survived in the arctic or the tropics, were spiky or smooth, were large as lobsters or small as fleas. And because they flourished for three hundred million years, they can be used to glimpse a less evolved world of ancient continents and vanished oceans. Erudite and entertaining, this book is a uniquely exuberant homage to a fabulously singular species.

Ordovician Trilobites of Southern Ontario, Canada and the Surrounding Region Paperback – January 1, 2015
by Phillip A. Isotalo (Author)
Trilobites are fascinating creatures that ruled the early Paleozoic seas. These arthropods first appeared in the Cambrian Period, lived for hundreds of millions of years and went extinct at the end of the Permian Period, around 251 million years ago, before the arrival of the dinosaurs. Trilobites lived in a variety of marine environments ranging from shallow tropical seas to the depths of polar oceans and were distributed globally.
The remains of trilobites are ubiquitous in Paleozoic Era sedimentary rocks of North America and are found throughout Southern Ontario, Canada, with trilobites also being found in neighboring Quebec and New York State. This book illustrates some of the best preserved Ordovician trilobites of the region and provides a thorough description of the trilobite species found in Southern Ontario.
This book will appeal to anyone interested in Paleozoic fossils and trilobites, from academics to beginning amateur and seasoned collectors. Ordovician Trilobites of Southern Ontario, Canada and the Surrounding Region is a comprehensive regional guide that explores an important part of Canada’s early geological history.

Wonderful Life: The Burgess Shale and the Nature of History
by Stephen Jay Gould (Author)
“[An] extraordinary book. . . . Mr. Gould is an exceptional combination of scientist and science writer. . . . He is thus exceptionally well placed to tell these stories, and he tells them with fervor and intelligence.”―James Gleick, New York Times Book ReviewHigh in the Canadian Rockies is a small limestone quarry formed 530 million years ago called the Burgess Shale. It hold the remains of an ancient sea where dozens of strange creatures lived―a forgotten corner of evolution preserved in awesome detail. In this book Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.
