So… Any idea what these are?
These are PENIS BONES. They are called the Baculum; the ones in the picture are from racoons. And NO. Humans DO NOT have these.
The baculum (also penis bone, penile bone or os penis) is a bone found in the penis of most placental mammals. It is absent in humans, but present in other primates, such as the gorilla and chimpanzee. A similar bone called the os clitoris in the female.
The baculum is used for copulation and varies in size and shape by species. Its characteristics are sometimes used to differentiate between similar species. A bone in the penis allows a male to mate for a long time with a female, which can be a distinct advantage in some mating strategies, such as mechanical support, sexual stimulation, sperm competition, and sexual selection.
Normally the baculum is inside the body and pushed out to the penis when sexual intercourse is needed. This creates a stiffness needed for penetration. So, when then is it not present in humans?
