Isingeniso se-Barinasuchus

I-Barinasuchus iwuhlobo olungasekho lwengwenya olwaluphila ngesikhathi seLate Cretaceous, cishe eminyakeni eyizigidi ezingama-70 edlule. Iwuhlobo olubalulekile emlandweni wokuziphendukela kwemvelo ngenxa yezici zayo eziyingqayizivele kanye neqhaza lalo ekuhlukaniseni ama-crocodilians. Lesi sihloko sihlose ukuhlola izici ezihlukahlukene ze-Barinasuchus, kusukela ekutholakaleni kwayo kanye ne-taxonomy kuya kuzici zayo zomzimba, indawo yokuhlala, indlela yokudla, kanye nendima yemvelo.

Ukutholwa kanye ne-Taxonomy ye-Barinasuchus

I-Barinasuchus yatholwa okokuqala ku-Barinas Formation yasentshonalanga yeVenezuela ngawo-1970. Izinsalela ezitholakele zazihlanganisa ugebhezi lwekhanda oluyingxenye, ama-vertebrae amaningana, namathambo esitho. Lezi zinsalela ekuqaleni zahlukaniswa njengezohlobo olusha lwengwenya, futhi kamuva ngo-1982, zaqanjwa ngokusemthethweni ngokuthi i-Barinasuchus arveloi. Igama lohlobo elithi "Barinasuchus" lisuselwa endaweni okutholwe kuyo, kuyilapho igama lezinhlobo elithi "arveloi" lihlonipha isazi se-paleontologist saseVenezuela uJosé T. Arvelo.

Izici Zomzimba ze-Barinasuchus

U-Barinasuchus wayeyingwenya enkulu, okulinganiselwa ukuthi yayifinyelele ubude obungamamitha angu-9 (amafidi angu-30). Yayinekhala ende nelincane, egcwele amazinyo abukhali, okubonisa ukudla kwayo okudliwayo. Ugebhezi lwekhanda luka-Barinasuchus lwaluqinile futhi lwakhiwe kahle, okusikisela ukuthi lwalunemisipha yomhlathi eqinile. Izitho zayo zase zikhule kahle, okubonisa ukuthi iyakwazi ukuhamba emanzini nasemhlabeni. Isakhiwo sonke somzimba we-Barinasuchus sasifana nesezingwenya zesimanje, nakuba sinezici ezithile ezihlukile.

Indawo yokuhlala kanye nokusatshalaliswa kwe-Barinasuchus

I-Barinasuchus yayihlala ezindaweni ezinamanzi ahlanzekile zalokho manje okuyi-Venezuela ngesikhathi seLate Cretaceous period. Cishe yayihlala emifuleni, emachibini nasemaxhaphozini, isebenzisa inala yokudla okutholakala kulezi zindawo. Ukusatshalaliswa okuqondile kwe-Barinasuchus akukaqinisekwa, njengoba izinsalela zayo zitholakale endaweni elinganiselwe. Nokho, ngokusekelwe ezihlotsheni zayo eziseduze nendawo ezungezile yesifunda, kusobala ukuthi iBarinasuchus yayinokusabalalisa okubanzi uma kuqhathaniswa kuyo yonke inyakatho yaseNingizimu Melika.

Ukuziphatha Kokudla kwe-Barinasuchus

Njengesilwane esizingelayo, i-Barinasuchus cishe yayidla inyamazane ehlukahlukene, kuhlanganise nezinhlanzi, izimfudu, nezilwane ezincane ezinomgogodla. Amazinyo ayo abukhali kanye nemihlathi enamandla kwakukufanelekela ukubamba nokubamba inyamazane yayo. I-Barinasuchus kungenzeka yaqamekela izisulu zayo emanzini noma emhlabathini, isebenzisa ukunyakaza kwayo okucashile nokushesha ukuze ibamangaze futhi ibanqobe. Ubukhulu bayo obukhulu kanye namandla anamandla okuluma bekuyoyenza ibe isilwane esizingelayo esesabekayo ohlelweni lwaso lwemvelo.

Iqhaza lika-Barinasuchus ku-Ecosystem

I-Barinasuchus ibambe iqhaza elibalulekile ku-ecosystem yayo yaseLate Cretaceous njengesilwane esizingelayo esiphezulu. Ngokulawula ubukhulu benani labantu abayizisulu zayo, yasiza ekugcineni ibhalansi yochungechunge lokudla. Ukuba khona kwayo bekungaba nomthelela ekuziphatheni nasekusabalaleni kwezinye izinto eziphilayo, kulolonge ukuguquguquka kwe-ecosystem. Ukwengeza, izinsalela ze-Barinasuchus zibonisa ukuthi yayinokujwayela kokubili ukuhamba kwamanzi nasemhlabeni, okuphakamisa ukuthi kungenzeka kube isixhumanisi esibalulekile ekuziphendukeleni kwengwenya.

Ukubaluleka Kokuziphendukela Kwemvelo kwe-Barinasuchus

I-Barinasuchus imele isigaba esibalulekile ekuziphendukeleni kwengwenya. Izici zayo eziyingqayizivele, njengekhala layo elide nelincane kanye nezitho ezikhule kahle, zinikeza ukuqonda okubalulekile emlandweni wokuziphendukela kwemvelo waleli qembu lezilwane ezihuquzelayo. Ngokutadisha i-Barinasuchus, ososayensi bangaqonda kangcono uguquko olusuka emanzini luye ekuzivumelaniseni nomhlaba kuma-crocodilians kanye nezici ezibe nomthelela ekuhlukeni kwazo.

I-Barinasuchus kanye ne-Diversification of Crocodilians

I-Barinasuchus ibhekwa njengohlobo olubalulekile ekuhlukaniseni ama-crocodilians. Izimpawu zayo ezingokomzimba, njengekhala layo elide kanye nogebhezi lwekhanda oluqinile, kukholakala ukuthi yizici zamadlozi ezabuye zashintshwa ngezinhlu zozalo ezihlukene. Ukuhlolwa kwe-Barinasuchus nezihlobo zayo kuye kwasikhanyisela ngezinqubo zokuziphendukela kwemvelo ezaholela ekuveleni kwezinhlobo ezihlukahlukene zezingwenya, kuhlanganise nezingwenya zesimanje ezijwayeleke kakhulu, izingwenya, nama-caiman.

I-Barinasuchus kanye ne-Evolution of Terrestrial Adaptations

Izitho ezikhule kahle ze-Barinasuchus zisikisela ukuthi yayikwazi ukuhamba emhlabeni, ngokunokwenzeka isebenzisa i-gait enwebekayo. Lokhu kuzijwayeza kokuhamba komhlaba kungenzeka kuvumele i-Barinasuchus ukuthi isebenzise indawo entsha nezinsiza, kube nesandla empumelelweni yokuziphendukela kwemvelo yamangwenya. Ucwaningo lwe-Barinasuchus lusisiza ukuthi siqonde uguquko ukusuka kokhokho basemanzini ngokugcwele baye kuma-semi-aquatic noma ngisho nezingwenya zasemhlabeni ngokugcwele.

I-Barinasuchus kanye Nobudlelwane bayo Nezingwenya Zanamuhla

I-Barinasuchus yabelana ngezici zomzimba eziningana nezingwenya zesimanje, njengekhala layo elide nemisipha yomhlathi eqinile. Lokhu kufana kusikisela ubudlelwano obuseduze bokuziphendukela kwemvelo phakathi kwe-Barinasuchus nezingwenya zesimanje. Kodwa-ke, i-Barinasuchus iphinde ibonise izici eziyingqayizivele ezihlukanisa nozakwabo besimanje, eqokomisa umlando oyinkimbinkimbi wokuziphendukela kwemvelo wama-crocodilians kanye nokwehluka okungaphakathi kwaleli qembu.

I-Barinasuchus kanye Nomcimbi Wokuqothulwa

Ngeshwa, isiphetho esiqondile se-Barinasuchus nokushabalala kwayo kuhlala kungaqiniseki. Kodwa-ke, ukuba khona kwayo eLate Cretaceous kusikisela ukuthi yayiphila ngesikhathi soshintsho oluphawulekayo lwemvelo kanye nesenzakalo sokuqothulwa kwenqwaba okwaqeda ama-dinosaurs angewona ama-avian. Ucwaningo lwe-Barinasuchus kanye nezinye izingwenya eziLate Cretaceous kunikeza ulwazi olubalulekile mayelana nemiphumela yalesi senzakalo sokuqothulwa emaqenjini ahlukene ezinto eziphilayo.

Isiphetho: Ifa lika-Barinasuchus

I-Barinasuchus inokubaluleka okukhulu emlandweni wokuziphendukela kwemvelo njengohlobo lwengwenya olubalulekile olwaluphila ngesikhathi seLate Cretaceous. Izici zayo eziyingqayizivele zomzimba, ukuzivumelanisa nezimo, kanye neqhaza ku-ecosystem kunikeza ukuqonda okubalulekile ezinqubweni zokuziphendukela kwemvelo ezilolonge ukuhlukahluka kwama-crocodilians. Ngokutadisha i-Barinasuchus, ososayensi bangathola ukuqonda okujulile kokuguquguquka kusuka emanzini kuya ekuzivumelaniseni komhlaba nezingwenya kanye nezici ezibe nomthelela ekuziphendukeleni kwazo. Ifa lika-Barinasuchus liyaqhubeka nokufaka isandla ekuqondeni kwethu umlando oyinkimbinkimbi nothakazelisayo wempilo yasemhlabeni.
