I judge that they could probably relate by the measurements taken of the bones contained by the x-ray next to comparison to an average human being of like peas in a pod sex and age.
Hi! All bones form within a process. Lenght, depth and shape adjectives determine the age of the bone and if it is fully formed or not. Obviously a femur of a child is drastically different than an adults. The lenght and shape of the bones in the mitt and fingers also let somebody know the age and later life of a creature. Bone ONLY developes to a solid point and after it begin to show the wear and rip. So most x-rays are pretty conclusive when determing the later life of the bone or not. M
While your long bones are growing within is something call a catilagenous "growth plate" essential any close, (this is different that the cartilage that forms at the ends of the bone).
The growth plate can be see contained by X-rays (actually the bone is see and the cartialge is not, so you see a opening between the shaft of the bone and the shutting of the bone). However once your long bones stop growing the growth plate become "fused" and is no longer detectable on an X-ray
