Lefatše la paleontology le ntse le tlala thabo e khaphatsehang ho tloha ha ho phatlalatsoa tšibollo ea bohlokoahali ea lehata la li-dinosaur la lilemo tse limilione tse 95 Winton, Queensland, Australia. Lehata le tsebisitsoe hore ke la a sauropod, sehlopha sa li-dinosaur tse khōlō, tse melala e telele tse kileng tsa solla lefatšeng. Se etsang hore se fumanoeng e be sa bohlokoa haholo ke hore ke lehata la pele le batlang le feletse le kileng la fumanoa Australia. Tšibollo ena e fana ka lintlha tse ncha mabapi le ho iphetola ha libōpuoa tsena tse hlollang ka botle 'me e ka thusa bafuputsi ho utloisisa hamolemo hore na ba phela le ho sebelisana joang le tikoloho ea bona.
Lehata le tsotehang e ne e le la sebōpuoa seo bo-rasaense ba se bitsitseng "Ann": setho sa mefuta. 'Diamantinasaurus matildae' e bonts'ang ho ts'oana ho makatsang le mesaletsa ea lintho tsa khale tse fumanoeng bohareng ba lefats'e, e fana ka boima ho khopolo ea hore li-dinosaur li kile tsa solla lipakeng tsa Australia le Amerika Boroa ka khokahano ea naha ea Antarctic.
E sibollotsoe ka Phuptjane 2018, sauropod Ann - e phetse lipakeng tsa 95m le 98m lilemong tse fetileng - ke mohlala oa bone feela oa mefuta ea eona e kileng ea sibolloa. Diamantinasaurus matildae e ne e le titanosaur, mofuta oa sauropod e neng e akarelletsa liphoofolo tse khōlō ka ho fetisisa tsa naheng tse kileng tsa e-ba teng historing. Ho sibolloa ha lehata lena le tsotehang ho nolofaletsa bo-rasaense ho bopa bocha ka lekhetlo la pele hore na sefahleho sa dinosaur se ne se shebahala joang.
Lehata le batlang le feletse la Diamantinasaurus matildae - ea pele e fumanoang Australia - e tsejoa ka ho ba le lihlooho tse nyenyane, melala e telele le mehatla, 'mele e kang moqomo, le maoto a mane a columnar.
Ho ka etsahala hore ebe Ann o ne a le bolelele ba limithara tse 15 ho isa ho tse 16 ho tloha hloohong ho ea mohatleng. Boholo ba boholo ba Diamantinasaurus bo bolelele ba limithara tse 20, bophahamo ba limithara tse 3 ho isa ho tse 3.5 mahetleng, ka boima ba lithane tse 23 ho isa ho tse 25. "Ho ea fihla moo li-sauropods li eang teng, li na le boholo bo mahareng, tse kholo ka ho fetisisa (li-sauropods) li sutumetsa limithara tse 40 ka bolelele le lithane tse 80 ka boima," ho boletse mofuputsi ea ka sehloohong, Dr. Stephen Poropat oa Univesithi ea Curtin.
Ho ea ka bafuputsi, "Masapo a lehata a ile a fumanoa ho pota-pota limithara tse peli ka tlas'a metsi, a hasane sebakeng se ka bang lisekoere-mithara tse robong. Boholo ba lehlakore le letona la sefahleho ha le eo, empa boholo ba le letšehali bo teng. Ka masoabi, masapo a mangata a bontša matšoao a ho sotheha (mohlomong e bile ka lebaka la ho hloekisoa kapa ho hatakeloa ka mor’a lefu), e leng ho etsang hore ho kopanngoa ha lehata ka ’mele e be ntho e bonolo.”
Lehata la Diamantinasaurus le ile la fumanoa nakong ea ho chekoa ka 2018 ke Australian Age of Dinosaurs Museum, empa e lutse e sa tlalehoa ho fihlela 2023. "Re ile ra qala ho fumana boholo ba masapo a maoto le vertebrae, empa ho pota-pota le leng la masapo a maoto ho ne ho e-na le masapo a manyenyane a qhalakaneng 'me ho ne ho le joalo. ho thata ho beha seo ba neng ba le sona," Poropat o boletse. Mel O'Brien, moithaopi, ka nako eo o ile a fumana “lesapo le shebahalang le makatsa hoo qetellong re ileng ra elelloa hore e tlameha ebe ke boko.

Ho sibolloa hona ho fane ka pono e sa tloaelehang ea tsela ea phoofolo ea tlhaho ho feta Antarctica e futhumetseng.
