ossamenta: Weasel skull (Default)
After the usual cattle, sheep, horse, pig and dog bones it's fun to find some (relatively) unusual species. If the bones are a bit wonky, so much the better. This one turned out to be bone of the (last) week!

It's a cat tibia, which has fractured across its upper part. The fibula has also fractured, become partially fused to the tibia and twisted 180°. A new joint facet has formed on the now inner side. The medial side of the tibia has an abscess, which indicates that when the fracture healed, an infection set in. The bone is smooth (although it has become very eroded in the soil), so the cat lived for a long while after the fracture.

Unfortunately the lower part of the fibula was never recovered from the pit.
