Palaeoecological deductions are vital for understanding the evolution and diversification of
species within prehistoric environments. This review highlights the multitude of ways in …

This chapter will cover clade definitions, the relationships within clades as well as the
occasional controversial relationships between different clades. Phylogenies arising from a …

Basal avialans have been the focus of numerous histological studies in the past decade,
from which different osteohistological patterns have been described. In this review, we look …

The explosive radiation of early birds has been well documented by the extraordinary
discoveries of the Early Cretaceous fossil birds in China in the past three decades. They …

Most crown-birds experience rapid growth, reaching adult size within a year. Rapid growth
strategies evolved within Aves multiple times during the Cretaceous, documented in the …

Abstract The late Miocene Dromornis stirtoni is the largest of the giant flightless dromornithid
birds. Here, we studied 22 long bones (femora, tibiotarsi, tarsometatarsi) of D. stirtoni to …

An unabated surge of new and important discoveries continues to transform knowledge of
pennaraptoran biology and evolution amassed over the last 150+ years.! is chapter …

The morphology of the pectoral girdle, the skeletal structure connecting the wing to the body,
is a key determinant of flight capability, but in some respects is poorly known among stem …

The study of the Cretaceous birds closest to the living euornithine species has mainly
focused on the evolutionary patterns leading to the modern group. Yet, the morphological …

Bone histology of crown-group birds is a research topic of great interest, permitting insight
into the evolution of remarkably high growth rates in this clade and variation across the …
