Homo erectus, an extinct species of hominid, had several distinct cranial characteristics that set it apart from both earlier and later hominids. Here are some of the key features:

1. Skull Size: Homo erectus had a larger braincase than its predecessors, with an average cranial capacity of about 900 cubic centimeters, though some individuals had a capacity of up to 1100 cubic centimeters. This is significantly larger than earlier hominids like Australopithecus, but smaller than later species like Homo neanderthalensis and Homo sapiens.

2. Skull Shape: The skull of Homo erectus was longer and lower than that of modern humans, with a pronounced brow ridge and a receding forehead. The back of the skull was also characteristically long and flat.

3. Facial Features: Homo erectus had a larger and more protruding face than modern humans, with large nasal openings and no chin. The teeth were also larger, especially the molars and premolars.

4. Thick Skull: The skull bones of Homo erectus were much thicker than those of modern humans. This is a trait shared with other early hominids.

5. Sagittal Keel: A distinctive feature of Homo erectus is the presence of a sagittal keel, a slight ridge of bone that runs along the top of the skull. This is not found in most other hominids.

These cranial characteristics, along with other skeletal features and evidence from tools and other artifacts, help anthropologists to identify Homo erectus fossils and to understand more about this important stage in human evolution.
