Unusual dagger, billfish or bone “blade”?

[thomas hauschild]

Some pictures to compare and for future investigations.

A complete Oosik/walrus-baculum with 55 cm.

A piece of oosik ( roughly grinded for a knifegrip ) and its cross-sections. The bigger end of an oosik will show more porosity than the thinner end. This piece was cutted out right in the middle.

A Oryx skull without the horn. This is just the inner bone. But this is very light with many porosity. It looks more like the last picture from the museum than an oosik.

Penis-bones are common, but much smaller, in fox, coyote, wolf, dog and bears with a big differences in length and form. I used a fossil one from an ice-age cave-bear as a knife grip. This specimen was about 20 cm and nearly straight.
