Anterior fontanelles from 19 fetuses over a range of gestational ages (from 8 weeks to full term) were obtained to study the anatomy and development in relation to the application of the principles of fontanometry. The most important feature was the development of an elastic membrane by 23 weeks' gestation; a subcutaneous layer of fat had appeared by 28 weeks' gestation.
