Ancient bones and other fossilised remains have been known to humans
for millennia but it is only over the past 300 years or so that their
true origins have been revealed. Until then, a rich folklore sought to
explain these enigmatic relics from the past. Every culture in every
country, it seems, wanted an explanation for the unusual objects and
bizarre shapes that often seemed to emerge, as if by magic, from the
ground.
Imagine a group of prehistoric hunters, whose trail has brought them to a
remote cave in northern Europe. They discover a cave and in it they find the
empty skull of a huge, unrecognisable beast sitting on top of a pile of
bones. It is easy to how the myth of cave-dwelling dragons who fed on other
large creatures might have come about.
In fact, the mysterious beast would have been a woolly rhinoceros, which
roamed Ice Age Europe before it went extinct about 10,000 years ago. Like
many animals before it, the rhino would have used caves to take refuge from
the elements - unaware that its bones would become entombed for thousands of
years.
In Japan, fossilised sharks' teeth were said to be the pointed thumbnails of
Tengu Man, a mythical mountain goblin. In India, the fossilised shell of
ammonites - marine molluscs - were known as saligrams, symbols of the god
Vishnu, which were kept in temples to purify water. In China, the fossils of
mollusc-like brachiopods were known as Shih-yen, or stone swallows, which
were said to be able to fly during thunderstorms.
Some fossils were ground into powder and taken as a potion to cure a rich
variety of ailments. Others, like the saligrams of Hindus and the "
tonguestones" of Christians, were dipped into drink to ward off evil.
Fossils were given exotic names in the many attempts to try to explain their
existence. "Names such as thunderbolts, tonguestones, toadstones,
snakestones and devil's toenails became widely used for different types of
fossils in Britain," says Paul Taylor, a fossils expert at the Natural
History Museum in London. Many resembled parts of the human body, and so
became associated with the practice of sympathetic medicine - curing like
with like. In Chinese medicine, the "dragon's teeth" used in some
recipes were in fact the teeth and bones of common animals.
It was not until the mid-18th century that the true nature of fossils began
to emerge. A physician called Steno, who lived and worked in Florence,
realised that the peculiar stone tongues that fell out of rocks were
actually the teeth of ancient sharks. He was able to prove his theory after
dissecting the head of a huge shark caught near Livorno in 1666. His "
eureka" moment was the beginning of the end for fossil folklore - and
the rest, as they say, is palaeontology.
An exhibition, Fossil Folklore, opens today at the Walter Rothschild
Zoological Museum in Tring, Hertfordshire, and runs until 8 July.
Protoceratops and the griffin
The fossil Protoceratops, which means "first horned face",
was a sheep-sized herbivorous ceratopsian dinosaur from the Upper Cretaceous
period (about 100 million years ago), that lived in what is now Mongolia.
Protoceratops had a large neck-frill but, unlike later ceratopsians, lacked
well-developed horns.
The folklore Fossilised skulls of this dinosaur with a bird-like
beak have been unearthed in the Gobi desert, which is where the myth of the
gold-guarding griffin originates - a ferocious beast with the body of a
lion, the head and wings of an eagle and talons as big as bull-horns.
The griffin myth probably originated from the tales of Scythian gold miners
who may have come across Protoceratops skulls on the edge of the Altai
mountains, in what is now Siberia. The uncanny resemblance between these two
creatures suggests that the fossilised skull and bones of the real dinosaur
may have been the inspiration for the vivid descriptions of the mythological
beast.
Pyramids, slave's lentils and angel's money
The fossil Nummulites are disc- or lenticle-shaped fossils with a
complex system of internal chambers arranged in a coil. Despite the fact
that they can reach 6cm in diameter, nummulites are the skeletons of
single-celled organisms (Foraminifera) that resembled the amoeba. They lived
on the sea-bed mostly during the Eocene and Oligocene periods (about 50 to
25 million years ago).
The folklore The Egyptian pyramids of Giza are built of limestone
packed with nummulites. Strabo the Geographer in the first-century BC was
told that the lentil-shaped fossils were remnants of the food of the slaves
who built the pyramids. Other nummulites have flat shells resembling coins
in shape and size; in folklore, they have been dubbed "angel's money"
.
Echinoids and jewstones
The fossil Balanocidaris is a sea urchin from the late Jurassic
period (about 160 to 145 million years ago). The delicate bodies of these
animals, distantly related to the starfish, often disintegrated after death.
However, club-like spines attached to the bodies of the living were more
robust, and survived to become fossilised.
The folklore Crusaders collected Balanocidaris fossils, which they
called "jewstones", from the Holy Lands and wore them as lucky
amulets. The fossils have also been traced back to Ancient Egyptian
communities from around 650BC. Sometimes apothecaries would grind the
bladder-like stones into a powder, to be used as a cure for various
urinary-tract problems.
Insects in amber and the DNA myth
The fossil When resin oozed from ancient trees, it sometimes trapped
insects and other small animals and plants. When it fossilised, the organism
was often perfectly preserved.
The folklore We can blame Michael Crichton, author of Jurassic Park,
for the myth that it is possible to extract dinosaur DNA from the last
blood-meal of a prehistoric mosquito trapped in amber, and use it to
reconstruct a dinosaur's genome and from that the animal itself.
In fact, any DNA that survived in amber would be so fragmented that it would
be impossible to recreate living dinosaurs from it. That didn't stop Steven
Spielberg from cashing in on the idea when he made the hugely successful
1993 film of Crichton's book.
Fish teeth and toadstones
The fossil Lepidotes is an extinct genus of ray-finned fish that
lived during the Jurassic and Cretaceous periods. Their bodies were covered
with thick scales and they had batteries of hard, round teeth to crush the
shells of their molluscan prey.
The folklore Lepidotes' teeth would often become separated from
their jaws and, when fossilised, took on the appearance of perfectly formed
little stones. Legend linked them to the mythical "jewels" that
were said to exist in the heads of toads. This myth can be traced back to at
least the time of the Roman natural historian Pliny the Elder (AD23 to 79),
and the idea is mentioned in As You Like It.
"Like tonguestones, toadstones were considered to be antidotes for
poison and were also used in the treatment of epilepsy," says Paul
Taylor of the Natural History Museum. From the 14th century, toadstones were
set in rings for their magical properties. The toadstone had to be taken
from an old toad that was still alive, and, according to the 17th-century
naturalist Edward Topsell, this could be done by placing a toad on a piece
of red cloth, which caused it to cast out its stone.
Fossil trees and giant serpents
The fossil Lepidodendron is an extinct genus of a tree-like plant
related to club mosses. They could sometimes grow to heights of 30 metres
and have trunks a metre thick, and thrived during the Carboniferous period
(360 to 300 million years ago).
Lepidodendrons had tall, thick trunks that rarely branched and were topped
with a crown of branches bearing leaves. The leaf scars on their trunks and
stems looked like tyre tracks or alligator skin.
The folklore Lepidodendrons' rotted and compacted remains formed the
coal seams exploited in Britain. After their leaves had fallen off, their
trunks became covered with diamond-shaped scars, which resembled the scales
of a reptile. As late as 1851 a specimen of this fossil tree was exhibited
in Neath as a gigantic fossilised serpent. Visitors could view the 8ft-long
specimen for the sum of one shilling (tradesmen six pence and working
classes three pence).
Lepidodendrons are now known as scale trees.
Oysters and devil's toenails
The fossil Gryphaea is an extinct genus of oyster from the Jurassic
period (200 to 145 million years ago). They lived on the seabed in shallow
waters, often in large numbers, feeding on plankton. Their fleshy parts
occupied the cavity between the two valves of their shells, just like modern
oysters, although the valves of Gryphaea were much thicker than those of
most modern oysters. The larger, curved valve rested on the mud of the sea
floor.
The folklore The thick, curved shells of Gryphaea were reminiscent of
a badly manicured "devil's toenail". The contorted shape of the
fossils also resembled arthritic joints, and in Scotland, devil's toenails
were used to cure joint pain, on the basis of the sympathetic-medicine
approach of like curing like.
Other local folkloric names for these fossils are "crouching stones"
, "cuckoo shells" and "Milner's thumbs". According to the
diary of Abraham de la Pryme for 10 April 1696, burnt and powdered Milner's
thumbs could cure the sore back of a horse in two or three days.
Belemnites and thunderbolts
The fossil Belemnites are an extinct group of marine molluscs. Like
squid, belemnites had torpedo-shaped bodies with long tentacles, but, unlike
squid, their arms, apparently, had hooks. Belemnites are common in rocks
formed during the Jurassic and Cretaceous periods, vanishing in the mass
extinction 65 million years ago.
The folklore When fossilised, Belemnites look like the sharpened tip
of a spear. In the Middle Ages, when fields in the Norfolk chalk and Oxford
clay outcrops of England were ploughed, they would appear after a
thunderstorm. The myth soon emerged that they were thunderbolts. It is more
likely that the heavy downpour had washed away the surrounding soil to
reveal the fossils. Belemnites are also known as "St Peter's fingers"
, "devil's fingers" and "ghostly candles".
Trilobites and water bugs
The fossil Trilobites are extinct arthropods that populated
Palaeozoic seas from the Cambrian (540 million years ago) to the Permian
(250 million years ago). More than 15,000 species have been described. The
typical trilobite was a woodlouse-like sea-floor creature; some species
sifted food particles from the mud, while others were active predators or
scavengers.
The folklore Fossil trilobites are common throughout the world. In
North America, the Pahvant people believed these little "water bugs"
had medicinal properties if worn as a necklace. Many trilobite fossils have
been found with small holes drilled into them to hold a thread. It was
believed that these fossils could guard against anything from a sore throat
to diphtheria and even stray bullets during the days of the Wild West.
A trilobite called Calymene was so abundant in the limestone once quarried
and mined around Dudley in the West Midlands that, until recently, it
appeared on the town's coat-of-arms. It became known locally as the Dudley
Bug or Dudley Insect and, during the 18th century, Dudley miners
supplemented their incomes by selling these attractive fossils.
Sharks' teeth and tonguestones
The fossil This fossilised shark's tooth is from Carcharodon
megalodon, a giant prehistoric shark from the Neogene (between about 23 and
five million years ago). Reaching an estimated 50 feet in length, it may
have been the largest predatory fish to have ever lived.
The folklore Fossilised sharks' teeth are fairly common. To the
ill-informed they must have been peculiar objects, often seeming eerily
well-polished even when dug fresh from the ground. Their similarity to
tongues led to the idea that they were the petrified tongues of serpents a
creature associated with the devil. It became a fairly common medieval
practice to dip a tonguestone in a glass of wine proffered at a banquet to
neutralise any poison that an enemy may have added to the drink.
Many tonguestones were unearthed on the island of Malta and their appearance
was used as evidence to support the folklore of St Paul, who was said to
have been shipwrecked on the island in AD60. "After being bitten by a
snake that rose out of a fire built to warm the shipwrecked sailors, St Paul
is said to have flung the snake back into the fire and cursed all of the
snakes on the island, causing them to lose their eyes and tongues,"
says the Natural History Museum's Paul Taylor.
Ammonites and snakestones
The fossil Ammonites are an extinct group of marine animals of great
value to geologists for correlating rocks of the same age in different
places. Their living relatives include octopus, squid, cuttlefish and the
pearly nautilus. The heyday of ammonites was during the Jurassic (200 to 145
million years ago).
The folklore Ammonites are one of the most common fossils found in
Britain. According to Paul Taylor, they were originally called Cornu
ammonis, or horns of Ammon, a Greek god with curled horns. "Ammonites
must have been puzzling objects to people unfamiliar with the existence in
the Indian and Pacific oceans of a living analogue the pearly nautilus,
" he says.
So ammonites became known as "snakestones" and were used as
evidence to back up stories of snakes being cast out by Christian saints,
from St Hilda, the Saxon abbess of Whitby, who turned out all the snakes
before building an abbey, to St Patrick of Ireland which has no native
snakes.
Snakes and serpents were seen as devilish, so it was important to cast them
out before building on a sacred place. Sometimes people carved a head of a
snake on the ammonite to reinforce the mythical story.
Hindus call ammonites from the Gandaki river in Nepal "saligrams".
They are believed to represent the discus or chakra held in one of the six
hands of the godVishnu.
Pygmy elephants and Cyclops
The fossil Several species of dwarf elephant evolved on different
Mediterranean islands during the Pleistocene (about two million to 10,000
years ago). Most of these originated from populations of normal-sized
elephants (Elephas antiquus) that colonised these regions when sea-levels
were low, and became isolated when they rose again.
The folklore Ancient people must have encountered the skulls of
extinct pygmy elephants on islands such as Malta and Sicily, where the
species thrived before the arrival of prehistoric humans. Although they had
evolved to become smaller, they were still relatively large animals with
bigger skulls than any other living animal in the vicinity. Anyone
unfamiliar with elephants could have easily imagined that the central nasal
opening in the animal's forehead was an eye socket. This interpretation may
have given rise to legends about a race of one-eyed giants. Intriguingly,
Homer's hero, Odysseus, lands on an island where there is a large cave the
home of Polyphemus the Cyclops. It is possible that the fossils of pygmy
elephants were first discovered in remote caves on islands such as Sicily.
Woolly rhinos and dragons
The fossil The woolly rhinoceros (Coelodonta antiquitatis) is an
extinct species that lived mostly during the Pleistocene (1.8 million to
10,000 years ago), surviving beyond the last ice age before becoming
extinct. It inhabited the northern steppes of Eurasia and this one was found
in Cambridgeshire. This plant-eater was about 3.5 metres (11 feet) long and
had a flat horn that enabled it to push aside snow to graze. The woolly
rhino had thick fur and fat to keep it warm in the cold.
The folklore There is strong evidence to suggest the fossilised bones
of woolly rhinos were taken to be the bones of dragons. The rhinoceros would
have been unfamiliar to ancient Europeans and its large, unusually shaped
skull could have easily inspired frightening fantasies about fire-breathing
creatures.
"The historical spread of dragons is the same as that of Pleistocene
fossil rhinos," says Andy Currant, ice age mammal curator at the
Natural History Museum. "The fact that no one recognised their anatomy
until about 1700 is significant. Dragons are usually linked to caves where
woolly rhinos are often found and rhino skulls have been found on bone
heaps."
