Period Carboniferous

Kweli xesha Carboniferous (elinye igama - Carboniferous) uninzi ilizwe liqulethe ezimbini zwekazi elikhulu: ajenos kunye Laurasia. Kweli xesha lokuqala nemozulu phantse naphi yimvula okanye sehlathi. iindawo Huge ngazo yi elwandle nzulu. amathafa amakhulu yonxweme ezisezantsi zogqunyelelwe ixhaphakile rhoqo yaye kwasekwa kumgxobhozo.

Kule sezulu nokufuma kwaye eshushu wokusasaza imithi yefeni ngokukhawuleza. ihlathi esinjalo zokwabiwa ubunzima ioksijini, yaye kungekudala isiqulatho igesi emoyeni lifikelele kwinqanaba yangoku. Eminye imithi ukufikelela ubude mane-emihlanu. Izityalo weza ngokukhawuleza ukwenzela ukuba izilwanyana ezingenamqolo, apho wayehlala emhlabeni, musa ukuba ixesha nexesha lokuba badle uze ukubola kubo. Ngenxa yoko, utyani uba ngakumbi nangakumbi.

Kwaba ngexesha Carboniferous baqale ukwakha iidipozithi afanayo. Xa imigxobhozo, bakhawuleza baya emanzini, nto leyo emenza abe iidipozithi zamalahle ezinkulu. abantu ngenxa Carboniferous unako ukuvelisa amalahle nokuvelisa ngoko zizinto ezahlukeneyo (umz, amalahle tar).

Xa Carboniferous kumgxobhozo kwakukho iintshinyela horsetails kunye yintlekele, kukho inani elikhulu yemithi emikhulu (ubulembu club kunye sigillaria efakelweyo). Ezi iimeko zokuhlala efanelekileyo ovumisa ngabantu eziphila yokuqala - krinodona kunye Ichthyostega for arthropods (izigcawu, amaphela, oohlabamanzi meganeura).

Ngelo xesha, ilizwe yaba Limi kuphela izityalo, kodwa ezinye izinto eziphilayo. Okokuqala, loo nto bephuma arthropods yamanzi, apho kamva wanika kubekho iqela izinambuzane. Ekubeni laqala uhambo yayo ehlabathini. Ngoku kukho malunga nezigidi iintlobo ezaziwayo yinzululwazi yale mihla. Ngokutsho ezinye iingqikelelo, malunga namashumi amathathu ezigidi nezesayensi kodwa ukuze ubone.

Enezityalo nezilwanyana ye Carboniferous

Xa amalahle ngexesha ukuyilwa wamalahle, oluthi luqokelelane ngenxa yokuba imithi bawa bengakwazi ukubola, uye emanzini. Apho yaphendulwa umgquba kunye namalahle. Phakathi uhlaza ngelo xesha kugcwele ngomfisi ukuya kwiimitha ezingamashumi amane anesihlanu, kunye amagqabi ngaphezu kokuba imitha. Kodwa imithi wakhula ubulembu club enkulu kunye horsetails. Yemithi inkqubo ingcambu nzulu kakhulu. Ngenxa yesi sizathu, zonke ngeenxa kwakugcwele ngemiboko yazo. Le ngokhuni manzi kwaye kufudumele. Iifeni ifikelele kubude iinkuni mihla. Babekwazi khona kuphela kwindawo ifumile. Kweli xesha Carboniferous kukho izityalo imbewu yokuqala.

A lot of imigxobhozo kunye ezazikwi- ube yokuza- zilungele ukuba eziphila emhlabeni nasemanzini okuqala kunye nezinambuzane ezininzi. yokuqala ukuvela izigcawu. Phakathi kwemithi emide zaye eziphaphazelayo amabhabhathane enkulu, eziphaphazelayo amaphela, mayflies kunye oohlabamanzi. Le uhlaza kancinci okunevumba, amasongololo isigebenga wahlala (centipede kunye amasongololo). Emanzini emehlweni umnwe kwaye ibekwe ibe ngaphezulu entloko tyaba, ububanzi. Oku kwamnceda arthropods ukubamba ukutya. Kungekudala Evolution okubangelwa eziphila ezinkulu (ukuya ezisibhozo ubude) embhoxo iinyoka mihla, kwakunye izidalwa ngaphandle imilenze,. eziphilayo ezinkulu bakhetha ukuqhubeka okuzingela emanzini, yaye ezincinane oogxa babo kwayeka phezu komhlaba.

Kukho izinto ezirhubuluzayo yokuqala - microsauria ngabona malovane ezincinane enamazinyo emifutshane abukhali, zazidiliza kumaqweqwe nzima zizinambuzane. Ulusu wabo ukufuma akubonakali waza wabanika ithuba lokuba bachithe ubomi babo ngaphandle kwemithombo. Ndizondle waba ngaphezu ngokwaneleyo: centipedes, iintsholongwane kunye nezinambuzane ezininzi. Xa ezirhubuluzayo ngcembe akukho mfuneko ukubuyela amanzi ukubeka amaqanda. Baza baqala ukubeka amaqanda kwiqokobhe bulishica. Amathole yimibhalo ezincinane zabazali babo.
