The Avian Acetabulum: Small Structure, but Rich with Illumination and Questions

Diversity, 2023
The idea that birds are maniraptoran theropod dinosaurs is now considered an evolutionary consensus. An “open” (i.e., completely or substantially perforate) acetabulum is considered an important synapomorphy verifying the bird–dinosaur nexus.
