Abstract
Analysis of ancient animal bone fractures can provide insights into ecological and behavioral aspects, as well as death processes and bone preservation modes. This paper describes and interprets the cause of a bone fracture observed in the fossil remains of a juvenile Myrmecophaga tridactyla (giant anteater) recovered from a limestone cave in Brazil. We identified an indirect bone trauma with a curved or spiral fracture line and a well-formed bone callus in the left ulna through a macroscopic and radiological examination. These features indicate that the giant anteater fell from a great height with an outstretched hand.
