Introduction: Asterion is the junction of parietal, mastoid part of temporal & occipital bones. It is related to junction of transverse and sigmoid sinuses. Developmentally asterion is the location of posterolateral fontanelle. Aim: To study the morphological features of asterion with or without sutural bones in 110 (220 sides) human adult dry skulls. Material & Methods: 220 sides of 110 dry adult skull bones of both male & female were studied, for the morphological features of asterion. Depending on the observations, classification is done as type I and type II. Results: Incidence noted is 20.9% are type-I and 79% are type-II. Conclusion: Presence of sutural bones at the asterion will be of greater significance, during neurosurgical procedures and also during radiological investigations.
