Cartilage covered surfaces

Not too long ago I hurriedly finished off a piece on the cartilage cap of bones in order to be in time with the spate of blog posts accompanying new work by Casey Holliday. However, in doing so, I forgot to include this rather nice image of the end of a sauropod longbone. You are probably used to seeing bones with lovely smooth ends as, while they too have a cap of cartilage, this helps the bones move freely past one another. In big bones on big animals however, where there is a big load of cartilage, it’s important that this is held in place on the bone itself and here the surface of the bone is not smooth but carunculated to provide a larger surface are for the two to bond together.

I´m working in Germany right now hence the paucity of posts this week, but normal service should resume shortly.
