Uniform, circular, and shallow enamel pitting in hominins: Prevalence, morphological associations, and potential taxonomic significance This study explores a particular form of enamel pitting originally identified in Paranthropus robustus. We call this uniform, circular, and shallow (U…

But how does it smell? An investigation of olfactory bulb size among living and fossil primates and other euarchontoglirans Analysis of cranial endocast data of 181 extant and 41 fossil species from Euarchontoglires shows that there was a reduction in olfactory bulb size in Crown Primates, but that there were also subsequ...

New paper co-led by Maddy Lang and myself, providing the most comprehensive analysis of the evolution of olfactory bulb size in living and fossil euarchontoglirans. anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...

A taxidermy gibbon with a massive inflated throat pouch.

#Gibbons are another of those animals that are rarely flattered by #taxidermy (many historic specimens were made by taxidermists who had never seen a whole one).
This #gibbon at the Sorbonne Zoology Museum has been given a neck-pouch that's bigger than its head.

Inter‐Observer Processing and Measurement Error Are Low for 2D Dental Measurements on Shared microCT Scans Objectives Sharing micro-computed tomographic (μCT) scans of teeth increases data accessibility and reduces the need for repeated scans of any given specimen. However, the use of the same TIFF stack...

Great new study in AJBA by Kaita N. Gurian and colleagues showing that multiple researchers can reliably use the same microCT scans for 2D dental measurements with minimal inter-observer error. Excellent news for scan sharing in dental anthropology!

Incisor Geometry, Relief, and Diet in Anthropoid Primates With Implications for Antillothrix Principal component analysis (PCA) showing variation in incisor shape across dietary groups. Diet is indicated by color, and genus is indicated by shape. (A) PCA of I1 height, width, and breadth. (B)...

Savannah E. Cobb and colleagues show how combining incisor geometry and relief offers a robust dietary proxy in anthropoid primates—outperforming geometry alone. Their findings suggest a mixed-feeding ecology for the fossil platyrrhine Antillothrix: onlinelibrary.wiley.com/doi/10.1002/...

Revisiting Linear Enamel Hypoplasia in Cayo Santiago Rhesus Macaques (Macaca mulatta): How a Stress Marker Relates to Environment and Maternal Lineage in a Rare Rhesus Colony With Known Life History Linear enamel hypoplasia (LEH) prevalence in the teeth of Cayo Santiago rhesus monkeys (Macaca mulatta). Defects matched on right and left teeth and the increase in the frequency of LEH by decade.

Fascinating new research by Debbie Guatelli-Steinberg et al., using enamel hypoplasia to study stress in the Cayo Santiago Rhesus macaques with known life history data. Published open-access in the American Journal of Primatology: onlinelibrary.wiley.com/doi/10.1002/... #primates #macaques
