Animals  of  the  Past 


*C 


N 


Prior  to  the  emergence  of  paleontology  and  comparative  anatomy  as  scientific 
disciplines  at  the  end  of  the  18th  century,  it  was  generally  known  that  there  were 
species  of  animals  that  had  disappeared  completely.  The  term  "extinction"  originally 
applied  to  the  extinguishing  of  fires  or  erasing  of  one's  debt.  It  was  not  until  1784 
that  the  term  extinction  was  used  to  denote  the  complete  eradication  of  a  species  of 
living  being.  In  1901,  Frederic  A.  Lucas  penned  an  overview  of  vertebrate  animals 
whose  only  evidence  of  being  remained  in  fossil  records.  The  book  focuses 
primarily  on  vertebrate  animals,  from  fish  to  mammals.
