Herein, developmental stages critical to the formation of the chondrocranium of the Red\u2010eared Slider, <jats:italic>Trachemys scripta<\/jats:italic> (Testudines: Emydidae), are described and illustrated, with particular attention given to ontogenetic changes that take place in the orbitotemporal region of the skull. Morphological descriptions are based on cleared and double\u2010stained and serially\u2010sectioned embryos. These specimens allowed for a detailed evaluation of the developmental morphology of the trabeculae, interorbital septum, pilae metoptica, taeniae marginalis, acrochordal cartilage, pilae antotica, parachordal cartilages, and crista sellaris. Additionally, the formation of the chondrocranium of <jats:italic>T. scripta<\/jats:italic> is compared to those of <jats:italic>Chrysemys picta<\/jats:italic> (Emydidae) and <jats:italic>Caretta caretta<\/jats:italic> (Chelonidae). Overall, the patterns of formation and remodeling of the chondrocranium are quite similar among these species, with the most conspicuous differences observed in remodeling of the posterior orbital cartilages (specifically, the pila metoptica). Reorganization of these cartilages is discussed briefly in the context of associated extraocular muscles for <jats:italic>T. scripta<\/jats:italic> and <jats:italic>C. caretta.<\/jats:italic> A prominent intertrabecula is reported in <jats:italic>T. scripta,<\/jats:italic> supporting previous observations of this structure in emydid turtles.
