Cartilage
In an embryo, the skeleton is originally made of cartilage. This cartilage gradually mineralizes and ossifies into bone in a process called endochondral ossification.
Hyaline cartilage is the forerunner of long bones in the embryo.

Most developmental bones in the embryo are made of cartilage, which later ossifies (hardens) to form bone. This process is known as endochondral ossification.
Um, I think it is...Cartilage?
Well bones in an embryo aren't really there yet until the embryo becomes multi cellular and more of a child. Even when the embryo becomes more complex the bones are still just cartilage the same material that makes up your nose. Over time a bone cell called osteoblast applies both calcium and phosphate thus the bones become more dense hope i answered your question
Cartilage
It is made up of mostly hyaline cartilage.
The skeleton of an embryo is originally made of cartilage, a flexible tissue that later undergoes ossification to become bone. During development, the cartilage is replaced by bone in a process known as endochondral ossification.
During endochondral ossification, the hyaline cartilage model in the embryo is gradually replaced by bone tissue. Osteoblasts deposit bone matrix around the cartilage model, which is then mineralized and eventually becomes mature bone tissue.
