-a fossil is any preserved — ‘remains’ / ‘impression’ / ‘trace’ — of any ‘once-living thing’ from a past ‘geological age’-
.
fossilis
‘classical latin’ –>
“obtained by digging”
.
(examples of ‘fossils’ include…)
‘bones’
‘shells’
‘exo-skeletons’
‘stone imprints’
(of ‘animals’ or ‘microbes’)
‘objects preserved in ‘amber”
‘hair’
‘petrified wood’
‘oil’
‘coal’
‘DNA remnants’
.
(the ‘totality’ of fossils is known as the fossil record)
.
*paleontology* –> “the study of ‘fossils”
(‘fossil age’ / ‘method of formation’ / ‘evolutionary significance’)
.
(‘specimens’ are usually considered to be ‘fossils’ if they are ‘over 10,000 years old’)
(the oldest fossils are around ‘3.48 billion years old’ to ‘4.1 billion years old’)
(the observation in the ‘1800s’ that certain ‘fossils’ were associated with certain ‘rock strata’ led to the recognition of a ‘geological timescale’ + the ‘relative ages’ of different ‘fossils’)
(the development of ‘radiometric dating techniques’ in the ‘early 1900s’ allowed scientists to quantitatively measure the ‘absolute ages’ of ‘rocks’ + the ‘fossils’ they host)
.
(there are many processes that lead to ‘fossilization’, including…)
‘permineralization’
‘casts’ + ‘molds’
‘authigenic mineralization’
‘replacement’ + ‘re-crystallization’
‘adpression’
‘carbonization’
‘bio-immuration’
.
(‘fossils’ vary in ‘size’ from ‘1-micrometer’ (1 µm) bacteria to ‘dinosaurs’ + ‘trees’, many meters long + weighing many ‘tons’)
.
(a ‘fossil’ normally preserves only a ‘portion’ of the ‘deceased organism’, usually that portion that was ‘partially mineralized’ during ‘life’)
(such as…)
*the ‘bones’ + ‘teeth’ of ‘vertebrates’*
*the ‘chitinous’ (or ‘calcareous’) exoskeletons of ‘invertebrates’*
.
(‘fossils’ may also consist of the ‘marks’ left behind by the ‘organism’ while it was ‘alive’)
(such as ‘animal tracks’ or ‘feces’)
(‘coprolites’ –> ‘fossilized feces’)
(these types of ‘fossil’ are called ‘trace fossils’ (or ichnofossils))
(…as opposed to body fossils)
.
(some ‘fossils’ are ‘biochemical’)
(these fossils are called chemo-fossils (or ‘bio-signatures’))
