rest in natural history； peabody had a museum built for him at yale andprovided funds sufficient for marsh to fill it with almost whatever took his fancy。
cope was born more directly into privilege—his father was a rich philadelphiabusinessman—and was by far the more adventurous of the two。 in the summer of 1876 inmontana while george armstrong custer and his troops were being cut down at little bighorn； cope was out hunting for bones nearby。 when it was pointed out to him that this wasprobably not the most prudent time to be taking treasures from indian lands； cope thought fora minute and decided to press on anyway。 he was having too good a season。 at one point heran into a party of suspicious crow indians； but he managed to win them over by repeatedlytaking out and replacing his false teeth。
for a decade or so； marsh and cope’s mutual dislike primarily took the form of quietsniping； but in 1877 it erupted into grandiose dimensions。 in that year a coloradoschoolteacher named arthur lakes found bones near morrison while out hiking with a friend。
recognizing the bones as ing from a “gigantic saurian；” lakes thoughtfully dispatchedsome samples to both marsh and cope。 a delighted cope sent lakes a hundred dollars for histrouble and asked him not to tell anyone of his discovery； especially marsh。 confused； lakesnow asked marsh to pass the bones on to cope。 marsh did so； but it was an affront that hewould never forget。
it also marked the start of a war between the two that became increasingly bitter；underhand； and often ridiculous。 they sometimes stooped to one team’s diggers throwingrocks at the other team’s。 cope was caught at one point jimmying open crates that belonged tomarsh。 they insulted each other in print and each poured scorn on the other’s results。
seldom—perhaps never—has science been driven forward more swiftly and successfully byanimosity。 over the next several years the two men between them increased the number ofknown dinosaur species in america from 9 to almost 150。 nearly every dinosaur that theaverage person can name—stegosaurus； brontosaurus； diplodocus； triceratops—was found byone or the other of them。
1unfortunately； they worked in such reckless haste that they oftenfailed to note that a new discovery was something already known。 between them theymanaged to “discover” a species calleduintatheres anceps no fewer than twenty…two times。 ittook years to sort out some of the classification messes they made。 some are not sorted outyet。
of the two； cope’s scientific legacy was much the more substantial。 in a breathtakinglyindustrious career； he wrote some 1；400 learned papers and described almost 1；300 newspecies of fossil （of all types； not just dinosaurs）—more than double marsh’s output in bothcases。 cope might have done even more； but unfortunately he went into a rather precipitatedescent in his later years。 having inherited a fortune in 1875； he invested unwisely in silverand lost everything。 he ended up living in a single room in a philadelphia boarding house；surrounded by books； papers； and bones。 marsh by contrast finished his days in a splendidmansion in new haven。 cope died in 1897； marsh two years later。
in his final years； cope developed one other interesting obsession。 it became his earnestwish to be declared the type specimen forhomo sapiens —that is； that his bones would be theofficial set for the human race。 normally； the type specimen of a species is the first set of1the notable exception being the tyrannosaurus rex； which was found by barnum brown in 1902。
bones found； but since no first set of homo sapiens bones exists； there was a vacancy； whichcope desired to fill。 it was an odd and vain wish； but no one could think of any grounds tooppose it。 to that end； cope willed his bones to the wistar institute； a learned society inphiladelphia endowed by the descendants of the seemingly inescapable caspar wistar。
unfortunately； after his bones were prepared and assembled； it was found that they showedsigns of incipient syphilis； hardly a feature one would wish to preserve in the type specimenfor one’s own race。 so cope’s petition and his bones were quietly shelved。 there is still notype specimen for modern humans。
as for the other players in this drama； owen died in 1892； a few years before cope ormarsh。 buckland ended up by losing his mind and finished his days a gibbering wreck in alunatic asylum in clapham； not far from where mantell had suffered his crippling accident。
mantell’s twisted spine remained on display at the hunterian museum for nearly a centurybefore being mercifully obliterated by a german bomb in the blitz。 what remained ofmantell’s collection after his death passed on to his children； and much of it was taken to newzealand by his son walter； who emigrated there in 1840。 walter became a distinguished kiwi；eventually attaining the office of minister of native affairs。 in 1865 he donated the primespecimens from his father’s collection； including the famous iguanodon tooth； to the colonialmuseum （now the museum of new zealand） in wellington； where they have remained eversince。 the iguanodon tooth that started it all—arguably the most important tooth inpaleontology—is no longer on display。
of course dinosaur hunting didn’t end with the deaths of the great nineteenth…century fossilhunters。 indeed； to a surprising extent it had only just begun。 in 1898； the year that fellbetween the deaths of cope and marsh； a trove greater by far than anything found before wasdiscovered—noticed； really—at a place called bone cabin quarry； only a few miles frommarsh’s prime hunting ground at o bluff； wyoming。 there； hundreds and hundreds offossil bones were to be found weathering out of the hills。 they were so numerous； in fact； thatsomeone had built a cabin out of them—hence the name。 in just the first two seasons； 100；000pounds of ancient bones were excavated from the site； and tens of thousands of pounds morecame in each of the half dozen years that followed。
the upshot is that by the turn of the twentieth century； paleontologists had literally tons ofold bones to pick over。 the problem was that they still didn’t have any idea how old any ofthese bones were。 worse； the agreed ages for the earth couldn’t fortably support thenumbers of eons and ages and epochs that the past obviously contained。 if earth were reallyonly twenty million years old or so； as the great lord kelvin insisted； then whole orders ofancient creatures must have e into being and gone out again practically in the samegeological instant。 it just made no sense。
other scientists besides kelvin turned their minds to the problem and came up with resultsthat only deepened the uncertainty。 samuel haughton； a respected geologist at trinity collegein dublin； announced an estimated age for the earth of 2；300 million years—way beyondanything anybody else was suggesting。 when this was drawn to his attention； he recalculatedusing the same data and put the figure at 153 million years。 john joly； also of trinity； decidedto give edmond halley’s ocean salts idea a whirl； but his method was based on so manyfaulty assumptions that he was hopelessly adrift。 he calculated that the earth
