Abashakashatsi bavumbuye amabara nyayo yitsinda ry’udukoko tw’ibinyabuzima twafatiwe muri amber muri Miyanimari mu myaka miriyoni 99 ishize. Udukoko twa kera turimo ibisimba byitwa cuckoo, isazi z’amazi n’inyenzi, byose bikaba biza mu kirere cy’ubururu, ibara ry'umuyugubwe n'icyatsi.
Kamere ikungahaye ku buryo bugaragara, ariko ibisigazwa by’ibinyabuzima ntibikunze kugumana ibimenyetso byerekana ibara ry’ibinyabuzima by’umwimerere. Kugeza ubu, abahanga mu bya paleontologue barimo gushakisha uburyo bwo gutoranya amabara y’ibimera byabitswe neza, byaba dinosaur n’ibikururuka hasi cyangwa inzoka za kera n’inyamabere.
Gusobanukirwa ibara ryubwoko bwazimye mubyukuri ni ngombwa cyane kuko birashobora kubwira abashakashatsi byinshi kubyerekeye imyitwarire yinyamaswa.Urugero, ibara rishobora gukoreshwa mugukurura abo mwashakanye cyangwa kuburira inyamaswa zangiza, ndetse bigafasha no kugenzura ubushyuhe.Kwiga byinshi kuri bo birashobora kandi gufasha abashakashatsi kwiga byinshi kubyerekeye urusobe rw'ibidukikije n'ibidukikije.
Mu bushakashatsi bushya, itsinda ry’ubushakashatsi ryaturutse mu kigo cya Nanjing Institute of Geology and Palaeontology (NIGPAS) cyo mu Ishuri Rikuru ry’Ubumenyi ry’Ubushinwa ryarebye ingero 35 za amber ku giti cye zirimo udukoko twabitswe neza. Ibisigazwa by’ibinyabuzima byabonetse mu kirombe cya amber giherereye mu majyaruguru ya Miyanimari.

Umwanditsi mukuru, Chenyan Cai yagize ati: "Amber ni hagati ya Cretaceous, afite imyaka igera kuri miliyoni 99, guhera mu bihe bya zahabu ya dinosaur."Ibimera n’inyamaswa byafatiwe mu mwobo mwinshi birarindwa, bimwe bifite ubudahemuka mu buzima. ”
Amabara muri kamere muri rusange agizwe mubyiciro bitatu bigari: bioluminescence, pigment, hamwe namabara yuburyo. Ibisigazwa by’ibinyabuzima byavumbuye amabara yubatswe yabitswe akenshi akaba akomeye kandi atangaje (harimo amabara ya metero) kandi bigakorwa nuburyo bwa microscopique ikwirakwiza urumuri ruherereye ku nyamaswa. umutwe, umubiri n'amaguru.
Abashakashatsi bahanaguye ibisigazwa by’ibimera bakoresheje ifu y’umusenyi hamwe nifu ya diatomaceous. Amber amwe amwe arahinduka uduce duto cyane kuburyo udukoko tugaragara neza, kandi materique ya amber ikikije hafi ya yose igaragara neza mumucyo mwinshi. Amashusho yashyizwe mubushakashatsi yarahinduwe hindura urumuri no gutandukanya.
Yanhong Pan, umwe mu banditsi b'ubwo bushakashatsi yagize ati: "Ubwoko bw'amabara yabitswe muri amber ya fosile yitwa ibara ry'imiterere." Pan nan yagize ati: yongeraho ko ubu “buryo bushinzwe amabara menshi tuzi mu buzima bwacu bwa buri munsi.”
Mu bisigazwa byose byavumbuwe, imyanda ya cuckoo iratangaje cyane, hamwe n'ubururu bw'icyatsi kibisi-icyatsi kibisi, umuhondo-umutuku, violet n'icyatsi kibisi ku mutwe, thorax, inda n'amaguru.Nk'ubushakashatsi bwakozwe, ubwo buryo bw'amabara bwahuzaga cyane imyanda ya kakao muri iki gihe. .Ibindi bihagaze harimo inyenzi z'ubururu n'iz'umuhengeri hamwe n'isazi y'icyatsi kibisi cyijimye.
Bakoresheje microscopi ya elegitoronike, abashakashatsi berekanye ko amber y’ibimera “yabitswe neza-ikwirakwiza urumuri rwa exoskeleton nanostructures.”
Abanditsi b'ubwo bushakashatsi baranditse bati: "Ibyo twabonye byerekana ko ibisigazwa bimwe na bimwe bya amber bishobora kubika amabara amwe n'udukoko twagaragaye igihe bari bazima mu myaka miriyoni 99 ishize." dusanga mu masaka ya cuckoo akiriho. ”
