The relationship between maxillary dental and occlusal anomalies: evidence of a ‘Maxillary Deficiency Syndrome’

open access: yesAustralasian Orthodontic Journal, 2018
Recent reports have suggested that anomalies involving the maxillary dentition can sometimes occur in combination. The aim of the study was to investigate combinations of maxillary dental anomalies relating to occlusal and skeletal factors which could ...

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

open access: yesThe Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

The effect of rearing density on skeletal anomalies in zebrafish, Danio rerio (Hamilton, 1822)

open access: yes, 2018
Rearing density can affect the welfare of farmed fish. In aquaculture, inappropriate high stocking density alters the animals’ nutritional status, condition indexes, growth rate and blood composition and they are also correlated with skeletal ...

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 ...

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

open access: yesThe Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

Pelvic morphology and body size in relation to the preauricular sulcus: Evidence from medieval to modern Iberia

open access: yesThe Anatomical Record, EarlyView.
Abstract The preauricular sulcus has long been debated as a pelvic feature variably attributed to obstetric stress, ligamentous traction, and broader biomechanical processes. To clarify its determinants, we analyzed 409 adult individuals from three archeological and one early modern skeletal collection from the Iberian Peninsula, integrating graded ...

Acetazolamide induced Skeletal Anomalies in Wistar Rat Fetuses

open access: yes, 2021
Aim:To induce skeletal anomalies in wistar rat fetuses by acetazolamide, using double stain technique for fetal rat skeleton with Alizarin Red S and Alcian blue. Method:Adult pregnant rats were randomly divided into two groups.

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 ...

An Observational Study of Skeletal Malformations in Four Semi-Intensively Reared Carp Species

open access: yesVeterinary Sciences
Cyprinids include some of the most widely farmed freshwater species. The aim of this study was to assess the incidence of skeletal malformations in carp species reared in semi-intensive systems in Albania: common carp (Cyprinus carpio), silver carp ...
