Description
The red staining (alizarin red) shows a region in
the head of a day 14 embryonic duck that is
undergoing membrane bone ossification. Membrane
bone forms much of the face and skull. This is
different to the other bones in the body where
cartilage is formed first and this is then
replaced with bone.
