Domestic Dog Skull Replica for Osteology Study

Historical and Evolutionary Data
Neomorphic cranial shapes and wider orbital angles distinguish this domestic dog specimen from wild wolves during comparative osteological research.
Specific Anatomical Observations (Natural History Museum, London)
Orbital Angle: Studies comparing archaeological dogs with wolves have identified a wider “orbital angle” (49-55° in dogs vs. 39-46° in wolves) in the zygomatic bone-forming orbit, which is a key marker of domestication.
Dental Formula: The dental formula remains the same as Canis lupus, but the carnassial teeth (PM4/M1) are often smaller in domestic dogs
Scientific Classification
- Kingdom: Animalia
- Phylum: Chordata
- Class: Mammalia
- Order: Carnivora
- Family: Canidae

- Binomical name: Canis lupus familiaris Linnaeus, 1758
- Conservation status: Least concern (IUCN 3.1)
Unique Comparative Collection Kit
To analyze the divergence between wild and domestic canids, this specimen pairs well with the gray timber wolf skull replica, the coyote skull replica, and the dhole male skull replica. This specific grouping therefore illustrates the significant change in orbital angles across different species.
