... platform surface using the Dirichlet normal energy (DNE) as a proxy for diet. DNE values increase with body mass, supporting the assumption that conodont metabolic rates increased faster than mass 0.67 . We finally find that adults in both taxa differ in their food bases, which supports trophic...

..., 1988 ; Liston, 2004 ; Friedman et al. 2010 ). Pachycormid diets and feeding strategies are poorly known: gut contents are known for few taxa and most of these observations are anecdotally based only on a single individual. Early Jurassic genera have been described as teuthophagous (Přikryl et al...

... ecology and are here imputed to biomineralization. Comparison with extant vertebrates suggests that the diet alone can explain the offset observed between bony fish and mosasaurs; however, breath holding due to a diving behavior in mosasaurs may have had some impact on their δ 13 C values, as previously...

In parallel, most coastal predators in the southwestern Atlantic Ocean shifted their diets following the decimation of their own populations, which resulted in a significant increase in their trophic positions and a reduction in the degree...

... ramnagarensis n. gen. n. sp.) currently represents the oldest record of fossil tupaiids in the Siwaliks, extending their time range by ca. 2.5–4.0 Myr in the region. Dietary analyses suggest that the new tupaiid was likely adapted for a less mechanically challenging or more frugivorous diet compared to other...

... ). Some African taxa (warthogs and giant forest hogs) are exceptional in that they diverged tremendously from omnivory and adopted highly herbivorous diets (e.g., Field 1972 ; d’Huart 1978 ; Viehl 2003 ; Kingdon 2015 ). This ecological divergence can be traced back to the late Miocene to mid-Pliocene...

... indicative of a more carnivorous diet (Ginot and Goudemand 2019 ). Using size as a proxy for trophic position has been observed to be somewhat inconsistent in modern cyclostomes, however, with a positive correlation among lampreys and no statistical relationship among hagfish (Romanuk et al. 2011...

The analysis of carbon and oxygen stable isotope ratios in bioapatite provides insight into the paleobiology of nonliving animals and the environment they used to inhabit. We applied this tool to investigate the diet of camelids from two geological...

We analyze the influence of evolutionary history on our ability to reconstruct diet from dental morphology in the mammalian order Carnivora, and we find that much of our understanding of diet in carnivorans...

..., but aspects of its biology remain unclear. In this study, we used multivariate dental topography analysis (DTA) to reconstruct the diet of N. magdalenensis by quantitatively comparing measures of molar complexity with those of 25 modern noctilionoid species representing all major dietary habits in bats. We...

Quantitative approaches for describing the occlusal surface of teeth have taken two contrasting approaches: shearing metrics and dental topography metrics. Shearing quotients (SQ) and shearing ratios (SR) disaggregate and measure features...

Paired antler–bone δ 13 C Coll and δ 15 N Coll from the same individual were used to identify differences between summer and annual diet and ecology. Intra-antler isotopic variability from serially sampled antlers was used to examine seasonal...
