We are excited to offer what is, perhaps, the only fetal skull with the calvarium cut. The detail present in this skull, including the ossicles, all calvarial sutures, and fontanelles, will guarantee its value as a teaching tool both for the educator and practitioner. By removing the calvarium, osteologists are able to learn the complex anatomy of the endocranium, especially including the pathways of the foramina of the skull base and the orbit.
