ImpactHigh impact

There is a consensus that the publication has a notable impact on the field of paleontology and contributes greatly to understanding turtle evolution.

Abstract in brief

  • The study focuses on a giant extinct sidenecked turtle from the Miocene era, found in Venezuela and Colombia, presenting new specimens that significantly expand our understanding of its anatomy and evolution.
  • The largest discovered shell measures 240 cm in length and indicates a mass of 1145 kg, far exceeding the size of both its closest living relative, the Amazon river turtle, and the largest extant turtle, the leatherback.
  • Findings suggest that there was likely a single giant turtle species in the northern Neotropics, displaying two shell shapes possibly indicating sexual dimorphism, and reveal evidence of interactions with large caimans.
