Morphology forms the most fundamental level of data in vertebrate palaeontology because it
is through interpretations of morphology that taxa are identified, creating the basis for broad …

Identification of the ontogenetic status of an extinct organism is complex, and yet this
underpins major areas of research, from taxonomy and systematics to ecology and …

Isolated theropod teeth are some of the most common fossils in the dinosaur fossil record
and are continually reported in the literature. Recently developed quantitative methods have …

Tyrannosauroids—the group of carnivores including Tyrannosaurs rex—are some of the
most familiar dinosaurs of all. A surge of recent discoveries has helped clarify some aspects …

Ontogenetic variation is documented within many dinosaur species, but extreme ontogenetic
changes are rare among dinosaurs, particularly among theropods. Here, we analyze 19 …

The Late Cretaceous (∼ 95–66 million years ago) western North American landmass of
Laramidia displayed heightened non-marine vertebrate diversity and intracontinental …

Numerous feathered dinosaur specimens have recently been recovered from the Middle–
Upper Jurassic and Lower Cretaceous deposits of northeastern China, but most of them …

In amniotes, the predominant developmental strategy underlying body size evolution is
thought to be adjustments to the rate of growth rather than its duration. However, most …

Despite nearly two centuries of investigation, a comprehensive understanding of dinosaur
biology has proven intractable. The recent development of means to study tissue-level …

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