Elemental models of primate nursing and weaning revisited

open access: yesAmerican Journal of Biological Anthropology, Volume 180, Issue 1, Page 216-223, January 2023., 2023
Abstract Objectives Intra‐tooth patterns of trace elements barium (Ba) and strontium (Sr) have been used to infer human and nonhuman primate nursing histories, including australopithecine and Neanderthal juveniles. Here, we contrast the two elemental models in first molars (M1s) of four wild baboons and explore the assumptions that underlie each ...

A multi-patient analysis of the center of rotation trajectories using finite element models of the human mandible [PDF]

open access: yesPlos one 16, no. 11 (2021): e0259794, 2022
Studying different types of tooth movements can help us to better understand the force systems used for tooth position correction in orthodontic treatments. This study considers a more realistic force system in tooth movement modeling across different patients and investigates the effect of the couple force direction on the position of the center of ...

Antler tine homologies and cervid systematics: A review of past and present controversies with special emphasis on Elaphurus davidianus

open access: yesThe Anatomical Record, Volume 306, Issue 1, Page 5-28, January 2023., 2023
Abstract Antlers are the most conspicuous trait of cervids and have been used in the past to establish a classification of their fossil and living representatives. Since the availability of molecular data, morphological characters have generally become less important for phylogenetic reconstructions.

Nonunion of the mandible [PDF]

open access: bronzeThe Laryngoscope, 1976
AbstractNonunion of the mandible was evaluated over a five‐year period (1968–1973). Fourteen cases were noted out of 577 mandibular fractures for an incidence of 2.4 percent.Causes of the complications were determined by a careful review of the poorly healing and successfully treated cases of mandibular fracture.

A review of helochelydrid shell material from late Albian to early Cenomanian greensands of Southern England, United Kingdom

open access: yesThe Anatomical Record, EarlyView., 2022
Abstract A number of helochelydrid turtle shell remains were recovered over the course of the 19th century from mid‐Cretaceous sediments throughout Southern England, including the poorly figured and described types of Trachydermochelys phlyctaenus from the Cambridge Greensand of Cambridgeshire, Plastremys lata from the Upper Greensand of the Isle of ...

Variation and development of the turtle chondrocranium, with a description of the common musk turtle (Sternotherus odoratus, Kinosternidae, Cryptodira, Testudines)

open access: yesThe Anatomical Record, EarlyView., 2023
Abstract Based on histological cross‐sections, the chondrocranium of the common musk turtle (Sternotherus odoratus) was reconstructed, described, and compared with other turtles. It differs from that of other turtle chondrocrania by possessing elongated, slightly dorsally orientated nasal capsules with three dorsolateral foramina, which might be ...

New data on the mammalian fauna from the late middle Eocene (MP 15–16) of Mazaterón (Soria, Spain): The youngest presence of the genus Prodissopsalis (Hyaenodonta, Hyaenodontidae) in Europe

open access: yesThe Anatomical Record, EarlyView., 2023
Abstract The Hyaenodonta were the most diverse carnivorous mammals in the European Eocene and were classically divided into three subfamilies: Sinopaninae, Arfianinae, and Proviverrinae, with this latter being the most successful of the three, as it exhibited a much larger geographic and temporal range.
