TL;DR: A specimen of a juvenile individual of Dinochelys from the Dry Mesa Quarry, Morrison Formation, provides the first record of the skull and neck in this genus as discussed by the authors, and is interpreted as related to Glyptops on the basis of a similar development of sculpture on the vertebral scutes of juvenile individuals.
Abstract: A specimen of a juvenile individual of Dinochelys from the Dry Mesa Quarry, Morrison Formation, provides the first record of the skull and neck in this genus. Dinochelys is interpreted as related to Glyptops on the basis of a similar development of sculpture on the vertebral scutes of juvenile individuals, and a similar development of a beak on the premaxilla and dentary. Desmemys, a turtle from the Early Cretaceous of Europe is interpreted as closely related to Dinochelys on the basis of similarities in the proportions of the scutes of the carapace and similar development of fenestration on the carapace and plastron. The relationship between Desmemys and Dinochelys further emphasizes the connections between the turtle assemblages of North America and Europe during the Jurassic and Early Cretaceous.

TL;DR: An incomplete carapace and plastron from the Peterson quarry in the Brushy Basin Member of the Upper Jurassic Morrison Formation, Bernalillo County, New Mexico is described in this article.
Abstract: We document an incomplete turtle carapace and plastron from the Peterson quarry in the Brushy Basin Member of the Upper Jurassic Morrison Formation, Bernalillo County, New Mexico. This is the first non-dinosaurian vertebrate from the Peterson quarry and the first Morrison Formation turtle from New Mexico. This specimen has the following combination of characteristics that supports its assignment to Glyptops plicatulus (Cope): low and oval carapace, surface ornamentation of small tubercles and raised ridges, peripherals not scalloped, no plastral fontanelles and mesoplastra meet at midline. The Glyptops record from New Mexico extends its distribution southward, almost to the southern edge of the Morrison depositional system and suggests that the turtles were part of one homogeneous Morrison vertebrate fauna. Glyptops has traditionally been reconstructed as an aquatic turtle, but a careful functional morphological analysis of Glyptops, particularly based on its limb proportions, is needed to verify its habitus.
