Toothless, two-legged dino from 70 million years ago found in Brazil

Dino-myt vind! Remains of a toothless, two-legged dinosaur that lived 70 million years ago are discovered in Brazil

  • The specimen was recovered by experts from the National Museum of Brazil
  • It was unearthed in a quarry in Cruzeiro do Oeste Municipality, Southern Brazil
  • The team said that the nearly-complete dinosaur specimen is a ‘very rare find
  • In die lewe, ‘Berthasaura leopoldinaewould have stood at some three feet in length
  • The fossilised remains of a toothless, two-legged dinosaur ontdek in Brasilië represent a new species that lived 70–80 million years ago, a study has determined.

    Researchers led from the National Museum of Brazil called the nearly-complete specimen — which they have named Berthasaura leopoldinae — a ‘very rare find’.

    It was unearthed in the ‘Cemitério dos PterossaurosQuarry in the Cruzeiro do Oeste Municipality of Southern Brazil’s Paraná State during fieldwork from 2011–2015.

    B. leopoldinae would have been a small carnivorous dinosaur, growing to only some three feet (een meter) in length and two and a half feet (80 cm) lank.

    Die navorsers, led by National Museum of Brazil palaeontologist Geovane Alves de Souza, said they were puzzled to find that B. leopoldinae sported a toothless, beak-like mouth.

    ‘That was a real surprise,’ the team said in a statement.

    The discovery of the type specimen, het hulle bygevoeg, was ‘one of the most complete dinosaurs found from the Cretaceous period in Brazil’.

    ‘The toothless part raises doubts about what kind of diet this animal had,’ Mr Alves de Souza explained.

    ‘It doesn’t necessarily mean it didn’t eat meat, wel.

    ‘Lots of birds, such as falcons and buzzards, eat meat with beaks.

    ‘Most likely, it was an omnivore living in an inhospitable environment where it had to eat whatever it could.

    B. leopoldinae is far from the first fossil find from the Cemitério dos Pterossauros site — as the Quarry’s name indicates.

    ‘The Cemitério dos Pterossauros Quarry is a very interesting locality that became famous for being the first pterosaur bone-bed from Brazil, showing two quite distinct species,’ het die navorsers in hul referaat verduidelik.

    The presence of dinosaurs at the site, egter, ‘was known right from the beginning,’ het hulle bygevoeg.

    The genus name Berthasaura was given in memory of the revered Brazilian zoologist and politician Bertha Lutz, wat gesterf het in 1976.

    B. leopoldinae’s species name, intussen, honours the 19th-century Brazilian empress and patron of the sciences, Maria Leopoldina.

    HOE DIE DINOSAURS UITGESTERF HET RONDOM 66 MILJOEN JAAR GELEDE

    Dinosourusse het die aarde regeer en oorheers 66 miljoen jaar gelede, voordat hulle skielik uitgesterf het.

    Die Kryt-Tersiêre uitsterwingsgebeurtenis is die naam wat aan hierdie massa-uitsterwing gegee word.

    Daar is vir baie jare geglo dat die veranderende klimaat die voedselketting van die groot reptiele vernietig het.

    In die 1980's, paleontoloë het 'n laag iridium ontdek.

    Dit is 'n element wat skaars op Aarde is, maar in groot hoeveelhede in die ruimte voorkom.

    Wanneer dit gedateer is, dit het presies saamgeval met wanneer die dinosourusse uit die fossielrekord verdwyn het.

    ’n Dekade later, wetenskaplikes het die massiewe Chicxulub-krater aan die punt van Mexiko se Yucatán-skiereiland ontbloot, wat uit die betrokke tydperk dateer.

    Wetenskaplike konsensus sê nou dat hierdie twee faktore verbind is en hulle is albei waarskynlik veroorsaak deur 'n enorme asteroïde wat na die aarde neergestort het.

    Met die geprojekteerde grootte en impaksnelheid, die botsing sou 'n enorme skokgolf veroorsaak het en waarskynlik seismiese aktiwiteit veroorsaak het.

    Die uitval sou pluime van as geskep het wat waarskynlik die hele planeet bedek het en dit onmoontlik gemaak het vir dinosourusse om te oorleef.

    Ander diere en plantspesies het 'n korter tydsverloop tussen generasies gehad wat hulle toegelaat het om te oorleef.

    Daar is verskeie ander teorieë oor wat die dood van die beroemde diere veroorsaak het.

    Een vroeë teorie was dat klein soogdiere dinosourus-eiers geëet het en 'n ander stel voor dat giftige angiosperme (blomplante) het hulle doodgemaak.
