The bony feature typically only found in babies is the fontanelle, commonly known as the "soft spot" on a baby's head. These are gaps between the bones of the skull that allow for flexibility during childbirth and accommodate rapid brain growth in infancy. As a child grows, these fontanelles gradually close as the cranial bones fuse together. The most prominent fontanelles are the anterior and posterior fontanelles, which usually close by the age of 18 months.

Babies are born without kneecaps, which are made of cartilage at birth. This does not impact their development as the kneecaps typically start to ossify and become bony by the age of 3-5 years.

The sagittal keel is primarily found in the skulls of certain hominin species, particularly in some early human ancestors and in certain modern human populations. It is a bony ridge that runs along the midline of the skull, typically associated with the shape and structure of the cranium. This feature is often discussed in the context of evolutionary biology and anthropology to understand variations in human cranial morphology.
The cassowary's most interesting feature is arguably its helmet. Properly called a casque, the helmet is a bony plate which sits vertically on the bird's head.
Fontanelles. These allow for the bony plates of the baby's skull to 'flex' during birth

Yes, a tubercle is indeed a small, rounded bony process. It serves as a site for muscle or ligament attachment and is typically found on various bones throughout the body. Tubercle shapes and sizes can vary depending on their location and function in the skeletal system.
Placoid scales are found in cartilaginous fishes and can be dermal or mesodermal in origin whereas cycloid scales are the bony scales found in bony fishes that are always mesodermal in origin.
Yes the lungfish are bony. There are also known as salamander fish they live in freshwater but today they can only be found in Africa, South America and Australia.
Yes, a stonefish does have a backbone. It is a type of bony fish belonging to the family Synanceiidae, characterized by its venomous spines and camouflage abilities. Like all bony fish, stonefish possess a vertebral column, which is a defining feature of vertebrates.
