Abstract in brief

  • Purussaurus brasiliensis was a massive prehistoric crocodilian from the Late Miocene in South America, estimated to grow up to 12.5 meters long and weigh about 84 metric tons.
  • Using modern crocodilian data, researchers suggest it had a powerful bite force of around 69,000 N, enabling it to prey on large vertebrates and dominate as a top predator without much competition.
  • Despite its size and strength offering significant advantages, its large body may have made it vulnerable to environmental changes, possibly contributing to its extinction as ecological shifts affected its long-term survival.

@BiodiversidadeB Só pra fazer propaganda do nosso trabalho que foi o mais recente a estimar o tamanho, a força-mordida e outros parâmetros do bichão. São fucking 7 toneladas métricas de força-mordida

@MesozoicDream @MarkusBhler10 @Antrodemus Thing is, Purussaurus’ bite force wasn’t measured by doing any modeling with its skull or anything. It was obtained based on its size estimate. Admittedly it did have a 140 cm skull, which compares favorably to T. rex, it’s just a matter of actually— https://t.co/fwBoyBE54S

@TheDarknix @gryposouza @tito_aureliano @alinemghilardi https://t.co/gUReBwf2Fb https://t.co/ExjuRJRM2u these are about Purussaurus brasiliensis, but there are also other species, P. neivensis from Colombia and P. mirandai from Venezuela @gryposouza can tell you everything we know (and don't know) about this giant!

It is a powerful beast with a bite force of 69,000N, which is 20 times that of a great white shark, or twice as powerful as a Tyrannosaurus rex. https://t.co/DA2DD3Z6pd
