RIP , me . I ’ve popped my clogs and fallen in a lake . All very distressing for friends and family , but finally , a womb-to-tomb ambition is about to be realized : I ’m on my manner to becoming a fossil . So , how long is my body going to have to wait for that sweetened , sweet permineralization ? And just when do I finally measure up as an – ahem – bona fide fossil ?
You might think it strange to prospicient to become a dodo , but the truth is that it ’s a rare privilege enjoyed by only the very few . Most animal that have lived on Earth will leave no tincture that can be detected in trillion of year , but die in just the right way , and you could be save in anything from calcium carbonate tofool ’s goldandopal .
What is a fossil?
The word fossil come from the Latinfossilismeaning “ unearthed , ” a meet lid - tip to these rarified cadaver we feel in the earth . Fossils do n’t have to be bones ; they can be vestige fossil like footprints , the preserved remains of plant , and even fossilized poop ( coprolite ) and vomit ( regurgitalites ) .
It only takes a few year for an animate being off-white to decompose , but if a beast dies in special circumstances , their remains can be filled in by minerals in the environment . This is know aspermineralization . So , how should you die if you want to become a fogy ?
“ The fossilization outgrowth is a very rarified process,”Dr Susannah Maidment , senior researcher in the division of Vertebrates , Anthropology , and Palaeobiology at the Natural History Museum , London , told IFLScience . “ Sometimes we have thing like skin and other soft tissue like feathers keep and usually that involve a quite alone curing of burial atmospheric condition , often very rapid burial . ”

“ If you imagine that your dinosaur perish on a flood knit stitch , something like the Serengeti , and it sort of keels over and choke , then all these other animals are drop dead to be coming along and pull it asunder . You ’ve got your vultures picking away at it , and lion involve bits , then bacteria break it down , and it ’s all pass away to get dragged all over the flood plain . "
“ What we need , really , is to take that beat carcase and the second it die , is to put it somewhere where that scavenging physical process and that rotting process ca n’t occur . A really good way is to bury it really , really rapidly . So , sometimes these animals light into lake or are overcome by sand sand dune , and that ’s what we take for soft character to be keep up . ”
Well , dong ding ding ! Here I lie in this lake , looking well on track to becoming as beautifully save as theKimmeridge Sea Monster . What happens next ?

When does fossilization begin?
The fossilisation cognitive operation itself can take anywhere from a matter of mean solar day to millions of yr . wait for mineral - rich groundwater to seep into bones means playing the long game , but there are some conditions scientists have discover can speed up and slow down the process .
A2017 studyexplored the event of microbial matte in the radioactive decay of African dwarf toad . The three - year study uncover that the frogs ’ body were rapidly entombed when decaying in microbic mats , creating a kind of sarcophagus that meant soft tissue remained entire for yr . Those frog also demonstrate mineralization within 540 days , or 1.5 years , which was see specially in the midbrain and skin , creating dodo - like rest in a comparatively short time period .
It seems microbial mats can play a significant role in speedy fossilization , and explicate why it is we sometimes get remarkably save fossils even of soft - bodied organism like thisfossil jellyfish . In just a matter of years brute can have fogy - similar mineralization , but does that qualify as a fossil ?
How long does it take for a fossil to form?
I might only be waiting a subject of years rather than billion of year for the fossilisation physical process to set out , but fossil - like brain does not a dodo make . To be qualified as a truthful fossil , uphold cadaver typically have to be former than 10,000 years , says theBritish Geological Society . That routine is more of a semantic particular than a defined second by which the fossilization process is complete , but it ’s a useful way to differentiate between old , well - save remains and what a museum might consider a dodo .
So , strap in , corpse of mine . The year 12,025 is at long last gon na be our year .
