About

It was so small, such a tiny, early, transitional mass, a coagulation of the unsubstantial, of the not-yet-substantial and yet substance-like, of energy, that it was scarcely possible yet–or, if it had been, was now no longer possible–to think of it as material, but rather as mean and border-line between material and immaterial.

Thomas Mann, The Magic Mountain, 1928.

This book tells the story of a scientific journey of twists and turns through assertions and denials, past alien monsters and incoming asteroids, through a world of unexpected discoveries and real utility, which ultimately arrives at an animal which, rather surprisingly, seems to say something about our own ancestry. In the course of all this travelling countless animals formed in scientific minds only then to dissolve, replaced by new apparitions. The fossils themselves were so small, that seeing them – really seeing them – was no easy matter. Indeed, the millions of these things, present in collections around the world today, might – if poured like so many grains of sand – fit into a few shoe boxes. We could be forgiven, then, for not knowing the conodont. But my aim in writing this book has not simply been to record a famous episode in the folk history of a science. Being so tiny and evocative, these fossils possessed a chameleon aspect. El Dorado-like, they pulled their victims into mirror-filled rooms, ensnaring their thoughts with mirages and illusions. Vanishingly small and impossibly ambiguous, they occupied that borderline between material and immaterial, never wholly one or the other. If one was not careful, it was possible to see in them what one wanted to see. What they saw then was no more than a thought; an imagined thing conjured into existence. If what the conodont workers thought they saw was then transcribed onto paper, one has, in these representations of the fossil, a tiny lens on the minds of those who found themselves inextricably entangled with these enigmatic material things. It was with this thought that I began this book and consequently my focus has been on fossils of the mind rather than their physical counterparts, for it was only in the scientific mind that these objects acquired their magical properties. 

So I positioned myself, like an anthropologist, on the edge of this scientific community…[taken from the concluding Afterword]

PRELUDE: The impossible Animal

As students, we sat there drawing and labeling a jargon-rich paleontological world only too ready to be captivated by the objects before us. Our tutor, however, seemed to have other ideas. He evidently had no passion for his subject. To him, ammonites and trilobites were just things to carry names. As each fossil was introduced in sequence, then drawn, annotated, named and removed, our enthusiasm waned. How could paleontology be so dull? Why would any tutor wish it to be so? Our disapproval turned to disdain. Then, one day, we were greeted by rows of binocular microscopes. We were to look at “microfossils” and, amongst these, some peculiar tooth-like objects. Immediately, and to our great surprise, everything now changed. Our roles were reversed. We initially thought these new objects dull (they were not the prettiest examples of their kind) but our tutor had woken up! He asked us what they were. We made a few feeble guesses which he easily rebuffed. He did, however, take our suggestions seriously. That too was new. Then he began to list other possibilities and each time explained that it too was incorrect. Before long, every blackboard in the room–and there were many–was covered with names and sketches of what seemed like the whole animal kingdom–and a few plants besides–and yet still we seemed no nearer the truth. We waited patiently for the inevitable answer, but that answer never came. Sporting a smile we had never previously seen, and with obvious relish, this dour Yorkshireman (or so we had thought) admitted he didn’t know what they were either. There was a moment of silence. Then we became brave. “What about…?”, “If…?”, “Couldn’t they…?” But our speculation was futile. In every case someone had been there before us. We looked again at these tiny teeth. They were so evocative. How could no-one have any sense of what they were? How could we not even know whether the animal which possessed them also possessed a backbone? How could a natural object exist in this advanced age and yet remain beyond the most general categorization? Undoubtedly enhanced by a perfect prelude–that dull journey through paleontological gems–our tutor’s performance had been quite brilliant. For years after, we would recall this impossible thing and dream a little about that magnificent moment when all would be revealed. Many years later, over a cup of coffee with curator, Peter Crowther, who was also one of the editors of the journal, Palaeontology, I recalled the wonder of this little fossil. His face lit up. It was clear that he, too, had experienced a similar moment. It was as though we had shared a religious rite of passage. Then he said, “And have you heard? They have recently found the animal!”
