impressions do not match the projecting, and supposedly corresponding, embellishments on the âfossilâ itself.)
But one style of fakery emerges as a kind of âindustry standard,â as defined by constant repetition and presence in all shops. (Whatever the unique and personal items offered for sale in any shop, this vin ordinaire of the genre always appears in abundance.) These âstandardsâ feature small (up to four or six inches in length) flattened stones with a prominent creature spread out in three dimensions on the surface. The fossils span a full range from plausible âtrilobites,â to arthropods (crabs, lobsters, and scorpions, for example) with external hard parts that might conceivably fossilize (though never in such complete exactitude), to small vertebrates (mostly frogs and lizards) with a soft exterior, including such delicate features as fingers and eyes that cannot be preserved in the geological record.
After much scrutiny, I finally worked out the usual mode of manufacture. The fossil fakes are plaster casts, often remarkably well done. (The lizard that I bought, as seen in the accompanying photograph, must have been cast from life, for a magnifying glass reveals the individual pores and scales of the skin.) The forger cuts a flat surface on a real rock and then cements the plaster cast to this substrate. (If you look carefully from the side, you can always make out the junction of rock and plaster.) Some fakes have been crudely confected, but the best examples match the color and form of rock to overlying plaster so cleverly that distinctions become nearly invisible.

When I first set eyes on these fakes, I experienced the weirdest sense of déjà vu, an odd juxtaposition of old and new that sent shivers of fascination and discomfort up and down my spineâa feeling greatly enhanced by a day just spent in the medina of Fez, the ancient walled town that has scarcely been altered by a millennium of surrounding change, where only mules and donkeys carry the goods of commerce, and where high walls, labyrinthine streets, tiny open shops, and calls to prayer, enhanced during the fast of Ramadan, mark a world seemingly untouched by time, and conjuring up every stereotype held by an uninformed West about a âmysterious East.â I looked at these standard fakes, and I saw Beringerâs Lügensteine of 1726. The two styles are so uncannily similar that I wondered, at first, if the modern forgers had explicitly copied the plates of the Lithographiae Wirceburgensis âa silly idea that I dropped as soon as I returned and consulted my copy of Beringerâs original. But the similarities remain overwhelming. I purchased two examplesâa scorpion of sorts and a lizardâas virtual dead ringers for Beringerâs Lügensteine , and I present a visual comparison of the two sets of fakes, separated by 250 years and a different process of manufacture (carved in Germany, cast in Morocco). I only wonder if the proprietor believed my assurances, rendered in my best commercial French, that I was aprofessional paleontologist, and that his wares were faux, absolument et sans doute âor if he thought that I had just devised a bargaining tactic more clever than most.

But an odd similarity across disparate cultures and centuries doesnât provide a rich enough theme for an essay. I extracted sufficient generality only when I realized that this maximal likeness in appearance correlates with a difference in meaning that couldnât be more profound.
