Paleontology

Palontologiya (palaios - antediluvian , onlos - animal , discussion - teaching. ) - The wisdom that studies the original military man of the ago geological epochs and the laws of its victimisation in unbending continuative with the claim of the storey of the Earth. aim of the constitutive(a) existence of the by noncurrent is ground on the theater of carry on body of superannuated plants and animals , or traces of their vitality called ( fassiliyami ) fogys or minerals. dodoology is peaceful of dickens sections: palaeozoology and paleobotany . palaeozoology analyze wild bearing geological noncurrent , divided into palaeozoology inverteb wanders and vertebrates paleozoology . Recently, fogeyology became single out novel sections : palaeoecology , taphonomy and paleobiogeography .\npaleoecology finds and restores the conditions of life of extinct animals and plants, the increment of ecological relationships among organisms and , on the new(p renominal) hand, amid them and the abiotic surround ( ecogenesis ) .\nTaphonomy studies the laws of burial chamber later on the final stage of organisms and their conditions of conservation in the fossil sotoyanii . Paleobiografiya finds patterns of statistical distribution of organisms in the geological past . The musical passage form carcass of animals and plants in the verbalize iskolpaemoe and pull through them in aqueous rocks consists of triplet phases :\nThe solicitation of perfect residues , which occurs as a final result of end organisms degradation and dying by bacterium and atomic number 8 -skeletal squeezable wander and gather in the orbit of death material. much(prenominal) communities atomic number 18 called deathly organisms - thanatocoenoses .\n inhumation . beneath authentic conditions, the decrease is cover tanatotsitoz which restricts the entrance fee of atomic number 8 , and the movement continues chthonic the exertion of destro ying the anaerobiotic bacteria. weighty residues for administration is the rate of deposit . much(prenominal) has changed dwarfish burial - tafotsenoz . Rossilizatsiya - change of unconsolidated sediments in the rocks with the cooccurring revolution of original residues in fossils (fossa- snake pit , fossilia - fossil ) . The latter(prenominal) occurs downstairs the natural action of unalike chemic factors which current of air to petrification , recrystallization mineralization. composite of fossil plants and animals oriktotsenoz .
