How do you tell if a bone is animal or human?
There are generally three levels of identification that can be utilized to distinguish between human and non-human animal bones: 1) gross skeletal anatomy, 2) bone macrostructure, and 3) bone microstructure (histology).
Is there an app to identify bones?
BoneID is a visual guide for forensic anthropologists, law enforcement, naturalists, and the simply curious. This site’s extensive and easy-to-use database will help you identify bones from many common species regardless of your academic training.
What are the three types of skulls?
Based on careful analysis, skulls are commonly categorized into three basic groups: European, Asian and African. Although the methods for determining origin are not 100 percent accurate, and many skulls may be a combination of ethnicities, they are useful for getting a general idea of race and origin.

What two things can we determine by looking at the skulls?
Skulls can tell us many things – what the animal ate, if it was an herbivore, omnivore, or a carnivore. Skull characteristics such as eye placement, teeth types (dentination), and jaw structure, can help tell us if the animal was a predator or prey.

How can you tell the age of a skull?
Skeletons record an adult’s age in several ways. The surfaces of the cranium, pubic bones, and rib ends hold clues. At the microscopic level, investigators can see the bone “remodeling” that takes place throughout life, as well as age-related bone breakdown.
Can you tell ethnicity from a skull?
It’s impossible to identify a person’s ancestry definitively from a single bone. Investigators can also take bone measurements using calipers, then input the data into a University of Tennessee database containing a reference library of measurements from more than 1,800 bones of known ancestry, age, and gender.

What do scientists use to identify information about skulls?
Forensic anthropologists determine the ancestry of a skeleton by examining the morphology, or shape, of the skull and by taking measurements of the skull vault (cavity) and face. By comparing these results with data from populations worldwide, scientists can evaluate that individual’s relationship to a world group.
