Jugal Morphology in Early Birds and Dinosaurs by Maurício Garcia is a document available to read on EtoBox.

This study examines the morphological differences between the jugal and quadratojugal bones in early birds and their dinosaurian relatives, highlighting the evolution of the jugal bar in modern birds. The research indicates that the jugal bar, crucial for cranial kinesis, evolved through the fusion of these bones, which were previously unfused in basal birds and non-avian dinosaurs. The findings suggest significant morphological modifications occurred during early bird evolution, contributing to the unique
