When encountering bones in natural settings, it is common to wonder about their origin. Deer bones are frequently discovered in various environments. Understanding their typical characteristics aids in identification, distinguishing them from other animal remains. This knowledge also informs responsible actions when such discoveries are made.
General Appearance and Texture
Deer bones typically exhibit colors from a bleached white or off-white hue in bones exposed to sunlight for extended periods to a yellowish-beige or light brown in more recently deceased or partially buried specimens. The surface of a deer bone often feels smooth and dense on its exterior. Internally, especially at the ends of long bones or within vertebrae, the structure becomes more porous and spongy.
Weathering can significantly alter the appearance of bones, leading to cracks, flaking, or a pitted texture on the surface. Despite these changes, the inherent density and robust nature of deer bones remain discernible. They generally feel solid and heavy for their size, unlike the more fragile bones of smaller creatures. The texture can also show signs of gnawing by rodents or other scavengers, leaving distinct tooth marks.
Identifying Specific Deer Bone Types
Deer skulls are identifiable by their deep eye sockets and a prominent nasal cavity. Male deer skulls feature pedicles, bony structures above the eye sockets from which antlers grow and are shed annually. The overall size of a deer skull generally ranges from 10 to 18 inches in length for common species like white-tailed deer.
The mandible, or lower jaw, is robust and possesses a distinct row of broad, flat molars and premolars adapted for grinding vegetation. Deer lack upper incisors, instead having a tough dental pad against which their lower incisors bite. This dental arrangement is a key indicator of their herbivorous diet and distinguishes them from carnivores or omnivores. Antlers, if present, are solid bone structures that grow from the pedicles and are typically branched, differing from the hollow, permanent horns found on animals like cattle.
Deer vertebrae vary in shape and size depending on their position. Cervical (neck) vertebrae are larger and more robust, while thoracic (chest) vertebrae have long, upward-pointing processes for muscle attachment. Lumbar (lower back) vertebrae are broad and flat. Limb bones, such as the femur (thigh bone), tibia (shin bone), humerus (upper arm bone), and radius/ulna (forearm bones), are long, slender, and dense. These bones feature distinct articular surfaces at their ends, which are smooth and specialized for joint movement.
Distinguishing Deer Bones from Other Animals
Differentiating deer bones from those of domestic animals often involves assessing size and specific anatomical features. Deer bones are generally more slender and less massive than those of adult cattle, even though both are herbivores with similar dental patterns. Sheep and goat bones are typically smaller and less robust than deer bones, though young deer bones might be confused with adult sheep or goat remains. The dental structure of deer, with their specialized grinding teeth and lack of upper incisors, clearly separates them from domestic carnivores like dogs, which possess sharp canines and shearing carnassial teeth.
When comparing deer bones to those of other wild animals, size is a primary differentiator. Bones from smaller carnivores like coyotes or foxes will be noticeably smaller and more delicate than deer bones. Bear bones, while robust, often exhibit different joint structures and tooth morphology, as bears are omnivores with more varied dental patterns than deer. Small mammal bones are significantly smaller and more fragile. If bones appear human, report the finding to local law enforcement or park authorities immediately.
What to Do When You Find Bones
When you encounter bones in the wild, handle them with caution. Wearing gloves is advisable to avoid direct contact, as bones can potentially carry bacteria or fungi, though the risk of disease transmission from dried bones is generally low. It is important to observe the bones without disturbing them significantly.
Many jurisdictions have regulations regarding the collection and possession of wildlife parts. In most areas, it is illegal to remove animal remains, including bones, from public lands without a permit. These laws are in place to protect wildlife and prevent commercial exploitation. Checking with local wildlife authorities or park rangers can provide specific information about regulations in your area.
If the bones appear to be human, or if there is a large number of bones suggesting an unusual death event, report the finding to local law enforcement or park authorities immediately. They can investigate the scene appropriately. For typical animal remains, leaving the bones in place allows them to naturally decompose and contribute to the ecosystem’s nutrient cycle, which is a beneficial ecological process.
