A Bilateral Division of the Parietal Bone in a Chimpanzee; with a Special Reference to the Oblique Sutures in the Parietal

"A Bilateral Division of the Parietal Bone in a Chimpanzee; with a Special Reference to the Oblique Sutures in the Parietal" by Aleš Hrdlička is a scientific exploration of a rare chimpanzee skull from the early 1900s. The heart of the story lies in the unusual division of the chimpanzee's parietal bones—a split never before fully seen—offering new insights into the world of primate anatomy. Through careful measurement and observation of this one-of-a-kind specimen, the publication compares its unique features to normal human and primate skulls to better understand this rare abnormality. It dives into possible implications for how skulls develop, making it an enriching experience for anyone interested in evolution and the secrets hidden within bone structure of a West African chimpanzee preserved at the American Museum of Natural History.
