Joang ho ahlola bong ba li-dinosaurs?

Hoo e ka bang liphoofolo tsohle tse phelang lesapo la mokokotlo li ikatisa ka ho ikatisa,soe entse li-dinosaurs. Litšobotsi tsa thobalano tsa liphoofolo tse phelang hangata li na le lipontšo tse hlakileng tsa ka ntle, kahoo ho bonolo ho khetholla banna le basali. Ka mohlala, lipikoko tse tona li na le masiba a matle a mohatla, litau tse tona li na le meetse e melelele, ’me e tona e na le manaka ’me e meholo ho feta e tšehali. Joaloka phoofolo ea Mesozoic, masapo a li-dinosaurs a patiloetlasafatše ka lilemo tse limilione tse mashome, le lisele tse bonoloeoe ka supa bongea li-dinosaursli nyametse, ho joalo ka 'neteboimaho khetholla bong ba li-dinosaur! Boholo ba mesaletsa e fumanoeng ke masapos, ’me ho ka bolokoa metsoako e fokolang haholo ea mesifa le letlalo. Joale re ka ahlola bong ba li-dinosaur ho tsoa mesaletsa ee?

Polelo ea pele e itšetlehile ka hore na ho na le lesapo la medullary. Ha Mary Schweitzer, setsebi sa paleonto Univesithing ea Carolina Leboea, United States, a ne a etsa phuputso e tebileng ea “Bob” (mesaletsa ea tyrannosaur), o ile a fumana hore ho na le lera le khethehileng masapong a mesaletsa ea lintho tsa khale, leo ba ileng ba le bitsa. mokong wa lesapo. Moko oa masapo o hlaha nakong ea ho tsoala le ho behela ha linonyana tse tšehali, 'me haholo-holo o fana ka calcium bakeng sa mahe. Boemo bo tšoanang le bona bo 'nile ba bonoa ho li-dinosaur tse' maloa, 'me bafuputsi ba ka etsa liqeto mabapi le bong ba li-dinosaur. Phuputsong ena, bosahali ba mesaletsa ea li-dinosaur e fetohile ntlha ea bohlokoa ho khethollang bong ba li-dinosaur, hape ke lesapo le bonolo ho feta ho tseba bong. Haeba lera la lesapo la porous le fumanoa ho potoloha lesapo la medula la lesapo la dinosaur, ho ka netefatsoa hore ena ke daenasore e tšehali nakong ea ho beoa. Empa mokhoa ona o loketse feela li-dinosaur tse fofang le li-dinosaur tse seng li loketse ho tsoala kapa tse seng li belehile, ’me li ke ke tsa khetholla li-dinosaur tse sa imang.

Ea bobelipolelo ke ho khetholla ho latela sehlopha sa li-dinosaur. Baepolli ba lintho tsa khale ba kile ba nahana joalobong e ne e ka khetholloa ka lihlopha tsa li-dinosaur, e leng mokhoa o neng o loketse ka ho khetheha bakeng sa Hadrosaurus. Ho ea katekanyoho fokola le boemo ba "moqhaka” eaHadrosaurus, bong bo ka khetholloa. Empa setsebi se tummeng sa paleonto Milner se hanana le sena, WHOsaid, “Ho na le phapang pakeng tsa meqhaka ea mefuta e itseng ea li-dinosaur, empa sena se ka nahanoa feela le ho hakanngoa.” Leha ho le joalore ba diphapangpakeng tsa li-dinosaur crests, litsebi li hlōlehile ho bolela hore na ke likarolo life tsa crest tse tona le tse tšehali.

Polelo ea boraro ke ho etsa likahlolo tse thehiloeng ho sebopeho se ikhethileng sa 'mele. Motheo ke hore liphoofolong tse anyesang le lihahabi tse phelang, e tona hangata e sebelisa likarolo tse khethehileng tsa ’mele ho hohela tse tšehali. Ka mohlala, nko ea proboscis e nkoa e le sesebelisoa se sebelisoang ke tse tona ho hohela tse tšehali. Ho nahanoa hore likarolo tse ling tsa li-dinosaur li sebelisetsoa ho hohela tse tšehali. Ka mohlala, nko e mokokotlo oa Tsintaosaurus spinorhinus le moqhaka oa Guanlong wucaii e ka ’na ea e-ba sebetsa sa boselamose se sebelisoang ke banna ho hohela tse tšehali. Leha ho le joalo, ha ho na mesaletsa ea lintho tsa khale e lekaneng ho tiisa sena hajoale.

Polelo ea bone ke ho ahlola ka boholo ba 'mele. Li-dinosaur tse matla tsa batho ba baholo ba mofuta o tšoanang e ka ’na eaba e ne e le tse tona. Ka mohlala, mahata a Pachycephalosaurus e motona a bonahala a le boima ho feta a basali. Empa phuputso e qholotsang polelo ena, e fana ka maikutlo a phapang ea thobalano mefuteng e meng ea li-dinosaur, haholo-holo Tyrannosaurus rex, e entse hore ho be le leeme le leholoanyane la temoho sechabeng. Lilemong tse ngata tse fetileng, pampiri ea lipatlisiso e boletse hore T-rex ea basali e ne e le kholo ho feta T-rex ea banna. Leha ho le joalo, sena se ne se ipapisitse le mehlala e 25 e sa fellang ea masapo. Re hloka lesapo le eketsehileng ho sekaseka ka botlalo litšobotsi tsa thobalano tsa li-dinosaurs.

Ho thata haholo ho tseba hore na ke bong ba liphoofolo tse timeletseng mehleng ea khale ka mesaletsa ea lintho tsa khale, empa lipatlisiso tsa bona li molemo haholo ho bo-ramahlale ba morao-rao ebile li na le tšusumetso ea bohlokoa mekhoeng ea ho phela ea li-dinosaur. Leha ho le joalo, ho na le mehlala e fokolang haholo lefatšeng e ka ithutang ka nepo ka bong ba li-dinosaur, ’me ho na le bafuputsi ba fokolang haholo ba saense mafapheng a amanang.
