The Iguanodontid Thread

    Not paleontology, I know, but I bet you immediatly thought of Iguanodon?

    This Japanese frog uses a bony spike on its "thumb" to stab its rivals, usually leaving scars, and also to secure the female during mating (also leaving her scarred). As if that wasn´t enough, the article mentions another species (a tree frog) that also has thumb spikes but specifically targets the eyes and ear drums of its rivals often with fatal consequences.

    Maybe Iguanodon and similar dinosaurs such as Ouranosaurus and Lurdusaurus used their spikes in similar ways- meaning, not only as defensive weapons but to fight same species rivals and perhaps even targeting the most vulnerable spots of their opponents. Going for the eyes and stuff. Scary.
