Which bones fuse together as you get older?

In this way, which bones are used to determine age?
Measuring the length of long bones can give an estimate of age for children, but this technique is useful only until bones have stopped growing. The tibia completes growth at about age 16 or 17 in girls, and 18 or 19 in boys. For toddlers to teenagers up to age 21, teeth are the most accurate age indicators.
what happens when bones fuse? Over time, most of this cartilage turns into bone, in a process called ossification. As the baby grows, some of its bones fuse together to form bigger bones. By adulthood, your skeleton contains just 206 bones. Growth occurs when cartilage cells divide and increase in number in these growth plates.
Furthermore, why do babies have 300 bones and adults 206?
Babies have more bones than adults because as they grow up, some of the bones fuse together to form one bone. This is because babies have more cartilage than bone. New born babies have around 305 bones. By adulthood, the skeleton has just 206 bones.
Why do babies have 300 bones?
When you're born, you have about 300 bones. The reason: As babies grow, some of their bones fuse together. Some infant bones are made entirely of soft, flexible tissue called cartilage that's slowly replaced by hard bone as the baby develops.
