Abstract An extreme, dorsally hyperextended posture of the spine (opisthotonus), characterized by the skull and neck recurved over the back, and with strong extension of the tail, is observed in many well-preserved, articulated amniote skeletons (birds and other dinosaurs, pterosaurs, and at least placental mammals). Postmortem water transport may explain some cases of spinal curvature in fossil tetrapods, but we show how these can be distinguished from causes of the opisthotonic posture, which… 
Opisthotonic head displacement in the domestic chicken and its bearing on the ‘dead bird’ posture of non‐avialan dinosaurs
TLDR
The findings show that the head remains freely mobile on the cervical column in all positions of displacement, and the cervical vertebrae can be grouped into three functional clusters (posterior, intermediate and anterior), based on their patterns of intervertebral excursion along the sagittal displacement arc.
The evolution of the feather: scales on the tail of Sinosauropteryx and an interpretation of the dinosaur’s opisthotonic posture
TLDR
The sequence of events in which this apparently occurred also suggests that the development of opisthotonus may have occurred post mortem rather than perimortem in this specimen, addressing a somewhat controversial question.
Re-evaluating Moodie’s Opisthotonic-Posture Hypothesis in Fossil Vertebrates Part I: Reptiles—the taphonomy of the bipedal dinosaurs Compsognathus longipes and Juravenator starki from the Solnhofen Archipelago (Jurassic, Germany)
More or less complete and articulated skeletons of fossil air-breathing vertebrates with a long neck and tail often exhibit a body posture in which the head and neck are recurved over the back of the
Ontogenetic similarities between giraffe and sauropod neck osteological mobility
The functional morphology of sauropod dinosaur long necks has been studied extensively, with virtual approaches yielding results that are difficult to obtain with actual fossils, due to their extreme
Osteology of Eoraptor lunensis (Dinosauria, Sauropodomorpha)
ABSTRACT We describe the basal sauropodomorph Eoraptor lunensis, based on the nearly complete holotypic skeleton and referred specimens, all of which were discovered in the Cancha de Bochas Member
Postcranial Axial Skeleton of Simosuchus clarki (Crocodyliformes: Notosuchia) from the Late Cretaceous of Madagascar
TLDR
Most aspects of the vertebral morphology of Simosuchus are consistent with those generally observed within Crocodylomorpha, however, the low number of caudal vertebrae indicates that the tail of SimOSuchus was remarkably short, shorter than in any other known croc Codylomorph.
Comparative anatomy and osteohistology of hyperelongate neural spines in the sphenacodontids Sphenacodon and Dimetrodon (Amniota: Synapsida)
TLDR
Observed histovariability appears to record the transition from the proximal to the distally protruding portion of the spine, and independent pathological evidence support the existence of a short dorsal crest in Sphenacodon and possibly other basal sphenacodontids.
Restoring Maximum Vertical Browsing Reach in Sauropod Dinosaurs

    Anatomical record
  • 2017
TLDR
This hypothesis is supported by the dorsally extended articulation of the only known co‐fused sauropod cervicals and is more readily restorable and biologically informative for long necked herbivores.
The Extent of the Pterosaur Flight Membrane
TLDR
It is strongly suggested that the trailing edge of the wing extended down to the lower leg or ankle in all specimens where the brachiopatagium is completely preserved, and is thus likely to have been universally present throughout the Pterosauria.

Morphology, histochemistry, and function of epaxial cervical musculature in the horse (Equus caballus)
TLDR

TLDR
A new sampling technique for fossil bone (coring with a 5/8” bit) was used to sample longbones of all four sauropod genera from the Upper Jurassic Tendaguru beds of Tanzania for paleohistological study, showing a common growth pattern in which growth is determinate but sexual maturity is achieved well before maximum size is reached.

TLDR
A student of the fossil vertebrates is almost sure to be impressed with the frequency of the peculiar curve to the backwardly bent neck and the rigid appearance of the limbs if these members are preserved in anything like the position assumed by the animal at death.

TLDR
Postmortem examination revealed atlantoaxial instability with ventral deviation of the axis due to malformation of the caudal atlas and cranial axis in an 8 mo old, male white-tailed deer.

TLDR
The distribution and ontogenetic features of pterosaur bone tissues, when combined with other evidence, suggest generally high growth rates, high metabolic levels, altricial birth, and extended parental care.
