Growth dynamics, skeletochronology, and histovariability of the theropod dinosaur Berthasaura leopoldinae

open access: yesThe Anatomical Record, EarlyView.
Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

Dental crown morphological variation and heterodonty in carcharhiniform sharks

open access: yesThe Anatomical Record, EarlyView.
Abstract Elasmobranch teeth are highly mineralized structures that constitute the majority of the fossil record for this group. Despite their taxonomic and evolutionary significance, detailed descriptions of dental morphology remain scarce. The order Carcharhiniformes, the most diverse among sharks, comprises 304 valid species that display remarkable ...

A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae

open access: yesThe Anatomical Record, EarlyView.
Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.

Paleopathology of a putative colossosaurian caudal vertebra (Neosauropoda: Titanosauria) from the Presidente Prudente Formation, Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Studies investigating paleopathologies in sauropods remain scarce despite their relative abundance in the fossil record. In this study we report new occurrence of paleopathological features, corresponding to a neoplasm found in a middle caudal vertebra (MCT.R.2120) of an advanced titanosaur from the Presidente Prudente Formation (Bauru Basin ...

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

open access: yesThe Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

The fossil record stays silent: Confusions and conundrums for hominin pelvis evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The evolution of the hominin pelvis is commonly modeled as a series of stages driven largely by the requirements of bipedal locomotion, reproduction, thermoregulation, and pelvic floor muscular support. These patterns are complicated by variation in canal dimensions in relationship with different changes in overall pelvic breadths. To quantify

Craniofacial growth, modeling, and estimation of milestones

open access: yesThe Anatomical Record, EarlyView.
Abstract Understanding craniofacial growth is foundational for research into intra‐ and interspecies variation, evolution, and clinical care. The Craniofacial Growth Consortium Study (CGCS), combines cephalographs from historical growth studies to create a dense longitudinal record of growth from 6 to 22 years of age.

Preoperative Risk Factors for Opioid Use Predict Self‐Reported Health and Function Up to 6 Months After Anterior Cruciate Ligament Reconstruction

open access: yesArthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To identify risk factors that predict the need for rescue opioid use and patient‐reported outcomes following an opioid‐limiting postoperative analgesia protocol after anterior cruciate ligament reconstruction. Methods This prospective cohort study recruited 44 patients undergoing primary arthroscopic‐assisted anterior cruciate ligament ...

Genetic and population analyses implicate thyroid‐related regulation of RNF144B in chondrocalcinosis

open access: yesArthritis &Rheumatology, Accepted Article.
Objectives Chondrocalcinosis, characterized by calcium crystal deposition within articular cartilage, affects 5–15% of the general population and has recently been identified as an osteoarthritis risk factor. However, Its biological pathways remain unclear.
