This has some interesting bits, but probably too technical/tissue-related on most of it for what you're after, but there are others listed which may be better.
The last 10 slides are most pertinent for you.
You can also check out google books.

I've moved from working on human remains to animal and I'm puzzled by
the unfused vertebrae of a raccoon. I have several epiphyses and I see
that they are paired, back to back, and joined by some material
(collagen?). I think this is different from human vertebrae.
How do they develop? Where do they start?
And is there any material available online about bone fusion and the
sequence? The assorted bones I've been given to identify appear to be
largely from immature animals. I'd like some pictures of unfused bones
to help me with identification.
