Probelesodon are small mammals that lived in Triassic[221-211] Argentina, along with Saurosuchus and Eoraptor, their nemesis's.
When a male Eoraptor and a female are chased into a Probelesodon's nest when chased by a Saurosuchus, one attacks the male, but the male kicks it out of the den and into the Saurosuchus's mouth, where it is killed by the Saurosuchus's closing jaws.
It is seen later when several of them go to an Eoraptor nest, and eat some eggs, but the female Eoraptor appears and kills two of them as they run away from her. When an Eoraptor baby goes out into the open, a pterosaur catches his eye, but he falls down and a Probelesodon attacks him, but the father Eoraptor grabs the mammal, shakes it and throws him against a rock, killing him.
