The fontanelles found on the infant skull are the sphenoidal (paired), mastoid (paired), anterior, and posterior fontanelles. These fontanelles are soft spots on the infant's skull where the cranial bones have not yet fully fused. However, in adult skulls, these fontanelles have fused and are no longer present.
