Entweni ephawulekayo etholakele, kuye kwatholwa izinyosi ezigayiwe ezifakwe emifeceni ogwini oluhle oluseningizimu-ntshonalanga yePortugal. Le ndlela engavamile yokwakhiwa kwezinto eziphilayo zasendulo inikeze ososayensi ithuba eliyingqayizivele lokutadisha ngokunembile ukuphila kwalezi zinambuzane zasendulo, bakhanyisele izici zemvelo okungenzeka bazithintile, futhi bakwazi ukuqonda umthelela wokuguquka kwesimo sezulu ezixukwini zezinyosi zanamuhla.
Izinyosi, ezilondolozwe ngezinga elikhethekile lemininingwane, zinikeza abacwaningi ulwazi ngobulili bazo, izinhlobo zezilwane, ngisho nempova eyashiywa umama. Sekukonke, izingosi ezine ze-paleontological ezigcwele lokhu kutholakala okungajwayelekile zitholwe esifundeni sase-Odemira e-Portugal, indawo ngayinye iziqhayisa ngokuminyana okuphezulu kwezinsalela zemifece yezinyosi. Kodwa mhlawumbe isici esithakazelisa kakhulu salokhu kutholakala ukusondela kwezinyosi ngesikhathi, njengoba le mifece yakhiwa cishe eminyakeni engu-3,000 XNUMX edlule.
Izinyosi ezomisiwe zingezohlobo lwe-Eucera, enye yezinhlobo zezinyosi ezingaba ngu-700 ezisahlala ezweni lase-Portugal namuhla. Ukuba khona kwazo kubuza umbuzo: yiziphi izimo zemvelo ezaholela ekufeni nasekulondolozweni okwalandela? Nakuba izizathu eziqondile zingakacaci, abacwaningi baye bacabanga ukuthi ukwehla kwezinga lokushisa ebusuku noma izikhukhula ezithatha isikhathi eside endaweni bekungaba nengxenye.
Ukuze uhlole lezi zibonelo eziyivelakancane, umphakathi wesayensi waphendukela ku-microcomputed tomography, indlela yokuthwebula esezingeni eliphezulu ehlinzeka ngezithombe ezinezinhlangothi ezintathu zezinyosi ezigayiwe ezifakwe ekujuleni kwemifece yazo evaliwe. Lobu buchwepheshe obusha kakhulu buvumela abacwaningi ukuba bahlole izakhiwo ze-anatomical eziyinkimbinkimbi futhi bathole ukuqonda okubalulekile empilweni yazo yangaphambilini.
Nakuba ukutholakala kwalezi zinyosi ezicwilisiwe ngokungangabazeki kuphawuleka ngokwako, imithelela yazo engaba khona eheha nakakhulu. Njengoba umhlaba ubhekene nezinsongo ezikhulayo ezibangelwa ukuguquka kwesimo sezulu, ukwehla kwezinqamuleli zempova ezibalulekile njengezinyosi sekuyinkinga ekhulayo yokukhathazeka. Ngokuqonda ukuthi lezi zinyosi zingase zithinteke kanjani ekushintsheni kwemvelo esikhathini esidlule, ososayensi banethemba lokuthola ukuqonda ngenani lezinyosi zamanje futhi bathuthukise amasu okuqina esikhathi esizayo.
I-Naturtejo Geopark, ehlanganisa isifunda sase-Odemira, idlala indima ebalulekile kulolu cwaningo. Njengengxenye ye-UNESCO World Network, i-geopark ihlanganisa omasipala abambalwa futhi izinikele ekulondolozeni nasekuhloleni izimangaliso ze-geological and ecological of the region. Ukutholakala kwezinyosi ezicwilisiwe kwenezela olunye ungqimba lokunotha ezinhlobonhlobo zezinto eziphilayo ezimangalisayo ze-geopark futhi kuqinisa ukubaluleka kwayo ekuqondeni ubunkimbinkimbi obuyinkimbinkimbi bezwe lethu lemvelo.
Okutholakele kushicilelwe kujenali Amaphepha kuPalaeontology. 27 Julayi 2023.
