Development of the nasal capsule in Emydura subglobosa (Testudines: Pleurodira) with a comparison to other turtles

The Anatomical Record, EarlyView.
Abstract Extant turtles occupy freshwater, marine, and terrestrial habitats, and their nasal region provides important evidence for the evolution of respiration‐ and sensory‐related cranial morphology. However, developmental data on the turtle nasal capsule remain limited, particularly in Pleurodira.

Anatomy and variation in the paraphyletic Mosasaurus lemonnieri assemblage from the Craie phosphatée de ciply, Belgium

The Anatomical Record, EarlyView.
Abstract Nineteenth century excavations of the Ciply‐Malogne Phosphatic Chalk Formation in Hainaut, Belgium, yielded over 50 partial mosasaur skeletons, the majority of which were referred to the species Mosasaurus lemonnieri Dollo, 1889. In the years since, this taxon has experienced a complicated taxonomic history, and its exceptional hypodigm has ...

Redescription of the cranial morphology of Amphisbaena braestrupi and Amphisbaena laurenti (Squamata: Amphisbaenidae) from the Pleistocene of Brazil using x‐ray computed tomography

The Anatomical Record, EarlyView.
Abstract Amphisbaenians (Squamata: Amphisbaenidae) are fossorial reptiles with highly specialized cranial morphology, yet their fossil record is frequently limited by fragmentary preservation. This study provides a detailed osteological redescription of the skulls of Amphisbaena braestrupi and Amphisbaena laurenti from the Pleistocene of Lagoa Santa ...

Assessment of intraspecific skull variation in the Campanian baenid turtle Plesiobaena antiqua

The Anatomical Record, EarlyView.
Abstract Baenids are freshwater paracryptodiran turtles with a fossil record ranging from the Early Cretaceous to the Eocene. The baenid Plesiobaena antiqua is the most common turtle in the Campanian (Late Cretaceous) Dinosaur Park Formation in Canada, but the apparent intraspecific variation remains poorly understood.

Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

The Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

Histological description and bone compactness analysis of fossil (Aldabrachelys sp.) and extant Aldabra giant tortoise (Aldabrachelys gigantea) shell bone fragments

The Anatomical Record, EarlyView.
Abstract Aldabra Atoll, north of Madagascar and part of the Seychelles Outer Islands, is home to the Aldabra giant tortoise, Aldabrachelys gigantea, the only survivor of several species of giant tortoises that were once widespread on islands across the Western Indian Ocean.

Morphological plasticity in the dentition of the lungfish Gnathorhiza from the Permian of Brazil: A population‐level geometric morphometric analysis

The Anatomical Record, EarlyView.
Abstract Dental plates are pivotal in the lungfish paleontological record, constituting highly mineralized structures resilient to diagenetic processes. This study provides a detailed description and quantitative shape analysis of 95 newly discovered Gnathorhiza sp. dental plates from the Middle–Late Permian Corumbataí Formation, Brazil.

Bioerosion traces in bones reveal an increase in ethological diversity in the insect exploitation of carcasses in the late Triassic

The Anatomical Record, EarlyView.
Abstract This study presents the first detailed description of bioerosion traces produced by insects in bones from the Santa Cruz Sequence (early Carnian, Santa Maria Supersequence, Brazil). An array of traces is reported, consisting of notches, a tube, trails of grooves attributed to the ichnotaxon Osteocallis mandibulus and ornamented depressions ...

Preoperative Sagittal Tibial Tubercle‐Trochlear Groove Distance Predicts Postoperative Outcome in Patients Undergoing Combined Trochleoplasty and Medial Patellofemoral Ligament Reconstruction

Arthroscopy, EarlyView.
Purpose To evaluate the association between the preoperative sagittal tibial tubercle‐trochlear groove (sTTTG) distance and postoperative patient‐reported outcomes after combined patellofemoral ligament reconstruction and deepening trochleoplasty in patients with recurrent lateral patellar instability and high‐grade trochlear dysplasia.

Outcomes of Capsular Plication as Part of Hip Arthroscopic Management for Surgically Identified Microinstability Are Comparable to Outcomes in Matched Controls

Arthroscopy, EarlyView.
Purpose To compare 2‐year minimum outcomes of hip arthroscopic management with capsular plication in patients with microinstability with propensity‐matched controls. Methods We searched primary hip arthroscopies undertaken between August 2009 and December 2020 from a single‐surgeon database, excluding those with lateral center‐edge angle <18°, for ...
