Flora va faunaning 
stratigrafik ahamiyati 
Fauna (lot. fauna — o rmon va dalalar xudosi, rim mifologiyasida hayvonlar podasi homiysi) — muayyan ʻ
hududda yoki akvatoriyada yashovchi hayvon turlari majmui. F. hayvonlarning turli guruhidan tashkil 
topgan bo lib, biror hudud faunistik kompleksining tarixiy rivojlanishi jarayonida vujudga keladi. Tundra, 	
ʻ
tayga, o rmon, dasht, yarim cho l, cho l, pantropik va boshqa faunistik komplekslar bor. Muayyan F.ni 
ʻ ʻ ʻ
tashkil etgan faunistik komplekslar miqdori turlicha bo lishi mumkin	
ʻ
Flora (yangi lot. fl ora, lot. Flora — gullar va bahor xudosi; lot. fl os — urug, fl oris — gul) — 
o simliklarning muayyan hududda tarixan tarkib topgan taksonlari majmui. F. muayyan geografik joyga 	
ʻ
taalluqli bo lib, uning hozirgi tabiiy sharoiti, o tmishi bilan bog liq va u yer yuzidagi boshqa F. bilan ozmi 	
ʻ ʻ ʻ
ko pmi munosabatda bo ladi. Bu jihatdan F. muayyan hududdagi o simliklar jamoasidan (o simliklar 	
ʻ ʻ ʻ ʻ
qoplamidan) farq qiladi. "F." tushunchasi ma lum hududdagi barcha o simliklar taksonlarini o z ichiga oladi. 	
ʼ ʻ ʻ
Tuban va boshqa yuksak o simlik turlari majmui, odatda, ma lum sistematik birliklar bilan belgilanadi 	
ʻ ʼ
(mas, "sporali o simliklar F.si", "suvo tlar F.si" va boshqalar). Florasi o rganilayotgan material hajmi ma lum
