Body mass is strongly related to both physiological and ecological properties of living organisms.
As a result, generating robust, broadly applicable models for estimating body mass in …

Predator-prey dynamics are an important evolutionary driver of escalating predation mode
and efficiency, and commensurate responses of prey [1–3]. Among these strategies, …

The analysis of morphological diversity frequently relies on the use of multivariate methods
for characterizing biological shape. However, many of these methods are intolerant of …

The causes, rate, and selectivity of the end-Cretaceous mass extinction continue to be
highly debated [1–5]. Extinction patterns in small, feathered maniraptoran dinosaurs (including …

Taphonomic biases dictate how organisms are represented in the fossil record, but their
effect on studies of vertebrate diversity dynamics is poorly studied. In contrast to the high …

Osteohistological data are commonly used to study the life history of extant and extinct
tetrapods. While recent advances have permitted detailed reconstructions of growth patterns, …

The unexpected discovery of non-avian dinosaurs from Arctic and Antarctic settings has
generated considerable debate about whether they had the capacity to reproduce at high …

Fossils were thought to lack original organic molecules, but chemical analyses show that
some can survive. Dinosaur bone has been proposed to preserve collagen, osteocytes, and …

Intraspecific aggression, or agonism, is a widespread intrasexual selective behavior important
to understanding animal behavioral ecology and reproductive systems. Such behavior …

Ceratopsid (horned) dinosaurs are an iconic group of large-bodied, quadrupedal, herbivorous
dinosaurs that evolved in the Late Cretaceous and were largely restricted to western …
