Prosthetic Hip Infection Secondary to Morganella morganii: A Rare, Morbid Condition

Osteology
Background/Objectives: Periprosthetic joint infection (PJI) is a challenging problem in orthopedic surgery and is often associated with high morbidity. The treatment becomes even more challenging whenever the microorganism is virulent and/or not widely ...

Osteology of Galeamopus pabsti sp. nov. (Sauropoda: Diplodocidae), with implications for neurocentral closure timing, and the cervico-dorsal transition in diplodocids

PeerJ, 2017
Diplodocids are among the best known sauropod dinosaurs. Numerous specimens of currently 15 accepted species belonging to ten genera have been reported from the Late Jurassic to Early Cretaceous of North and South America, Europe, and Africa. The highest

Almost billfish: convergent longirostry, micro‐dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy

Journal of Anatomy, EarlyView.
A fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.

Redescription of the Oldest Crown Clade Penguin: Cranial Osteology, Jaw Myology, Neuroanatomy, and Phylogenetic Affinities of Madrynornis Mirandus

Journal of Vertebrate Paleontology, 2018
Madrynornis mirandus, one of the few fossil penguins known from a nearly complete articulated skeleton, represents a key taxon for understanding the stem-crown transition in penguins.

The secret in their eyes: A review of the recessus orbitalis, a unique structure of flatfishes

Journal of Anatomy, EarlyView.
The recessus orbitalis is an organ responsible for projecting the eyeball above the level of the head and is uniquely present in flatfishes. The organ consists of two interconnected chambers filled with interstitial fluid and is internally coated with smooth muscle fibers that act as a double‐pump system.

The effect of remaining in water in estimation of time since death in skeletal remains

Medicine Science, 2017
Determining the time since death of an individual from skeletal remains is a challenging stage. In determination of time since death, climate conditions, environmental factors, conditions such as whether the body was buried or not, and genetic and ...

Embryological development and comparative analysis of Anguis colchica (Nordmann, 1840): Insights into ossification and morphological traits in anguimorph lizards

Journal of Anatomy, EarlyView.
This study examines the embryonic development of Anguis colchica across three stages, highlighting key morphological and skeletal features. Ossification begins before stage 6, with cranial bones forming early, while frontal and parietal bones remain unfused at stage 7.

Osteology and arthrology of the ankle and tarsometatarsus of anoles (Iguania: Anolidae): not convergent with geckos but divergent from the ancestral iguanian condition

Journal of Anatomy, EarlyView.
Geckos and anoline iguanid lizards are well‐known for their possession of adhesive toepads, which are generally regarded as being convergent structures. We show that the anatomical configuration of the foot in these two lineages differs markedly and that these differences likely relate to the contrasing ways they deploy their adhesive systems and ...
