Palaeobiology

Life history

The P1 element of Epigondolella rigoi exhibited positive growth allometry of the platform area and length with respect to the length of the element. Because the P1 elements functioned akin to molars in mammals, this suggests elevated needs for energy as members of the species grew.[3]
