Yes, that's correct. Bones that form between sheets of fibrous connective tissue develop through a process called intramembranous ossification. Here are the steps:

1. Mesenchymal cells, which are essentially stem cells, cluster together and start to differentiate into specialized cells.

2. These cells become osteoblasts, which are bone-forming cells.

3. The osteoblasts start to secrete a matrix material, which includes collagen and other compounds. This matrix starts to harden due to the deposition of calcium salts, a process known as calcification.

4. As the matrix forms and hardens, it develops into trabeculae. The trabeculae join together to form spongy bone.

5. Eventually, some of this spongy bone may be replaced by compact bone, especially on the outer surfaces of the bone.

6. Finally, the periosteum, a protective layer of connective tissue, forms around the bone.

This process is how flat bones like those of the skull and clavicle are formed.
