Hi, we had the same problem a few months ago so after following this thread got the notification of a new post. I don't have any pictures unfortunately but here's how we fixed our Zoomer Dino:
There are approx six 'vertebrae' or tail pieces.
Line up these tail pieces according to size, keeping those with the white mark on top.
You'll notice four threads hanging from the 'intact' end of the tail. Each vertebra piece has four holes and you'll need to thread each of these threads through the holes one by one to reconnect the tail.
Using a crochet hook or loom band tool, pull thread through and hang it on each of the four notches of the vertebra.
When you get to the sixth vertebra it's trickier as the holes are small. We used a paper clip, pulled apart the end, and looped the thread around it to pull it through. Once you connect this last piece the tail will be fixed. The remaining vertebrae can be connected with super glue if needed.
I hope that helps!
