The axial skeleton of the tuatara (Rhynchocephalia: Sphenodon): insights on intraspecific variability, ontogeny, sexual dimorphism, and remarks on fossil taxa Abstract. As the sole living rhynchocephalian, the tuatara (Sphenodon punctatus) provides important comparative information for fossil rhynchocephalians an

As the sole living genera of an ancient order of reptiles, tuataras are key for fossil comparisons of extinct species & modern lepidosaurs (lizards & snakes). Here, their axial skeleton is described in detail, offering new insights to this unique creature...Tuatar-ya interested? 🌍🧪👇
