Myological and osteological approaches to gape and bite force reconstruction in Smilodon fatalis

The Anatomical Record, Volume 308, Issue 11, Page 2944-2961, November 2025.
Abstract Masticatory gape and bite force are important behavioral and ecological variables. While much has been written about the highly derived masticatory anatomy of Smilodon fatalis, there remains a great deal of debate about their masticatory behaviors.

Dental microwear texture analysis of extant sika deer with considerations on inter-microscope variability and surface preparation protocols

Biosurface and Biotribology, 2017
Recently, dental microwear texture analysis (DMTA) has been applied to various kinds of vertebrates to infer dietary preference. More data are needed on inter-microscope variability to assure the objectivity and repeatability of this method.

Dental microwear and controlled food testing on sheep: The TRIDENT project

Biosurface and Biotribology, 2017
Here, we present a short review of the most recent results that have come out of the TRIDENT project. This project aims to model tooth wear by performing controlled food testing on sheep. This approach offers us the opportunity to test various scientific

Was the giant short-faced bear a hyper-scavenger? A new approach to the dietary study of ursids using dental microwear textures.

PLoS ONE, 2013
Dramatic environmental changes associated with global cooling since the late Miocene, and the onset of glacial-interglacial cycles in the Pleistocene served as a backdrop to the evolutionary radiation of modern bears (family Ursidae). These environmental

Assessing tooth wear progression in non-human primates: a longitudinal study using intraoral scanning technology [PDF]

PeerJ
Intraoral scanners are widely used in a clinical setting for orthodontic treatments and tooth restorations, and are also useful for assessing dental wear and pathology progression.

Tooth replication techniques, SEM imaging and microwear analysis in Primates: methodological obstacles

, 2004
Dental microwear analyses are among the most significant techniques though which a researcher can make dietary and ecological inferences from primate fossil specimens. Hard particles, such as plant phytoliths or silica-base sands, can scratch tooth enamel surfaces during food mastication producing a dietary specific pattern of microwear on the enamel ...

Intra-specific foraging dynamics reveal anthropogenic impact on harbour seals (Phoca vitulina) in the Danish Kattegat and the German Wadden Sea

Frontiers in Marine Science
IntroductionMarine mammals are apex predators in the marine environment and seals are known as opportunistic hunters which adapt to prey availability in their distribution range. Knowledge about harbour seal diet is a crucial baseline parameter to assess

Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

The Anatomical Record
AbstractDental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.
