There are a few things that could mete out excess bone growth, including spondylolisthesis and spina bifida (which are very rare). But one of the more adjectives occurrences happen when the sacrum fuses. The sacrum is a set of five bones right above your tail bone. When born, the saccrum is still 5 distinct bones, but as you grow, they fuse together and become one large bone system. Sometimes during this process, extra calcium deposits form around the sacrum and inflict bony extrusions.
If you have any concerns, be aware of free to talk to your orthopaedist. They could point you within the right direction.
Hope this helps!
yess it is possible for even a human to develop a tail of some sort. This is call spina bifida. This is caused by incomplete closure of an embryonic tube and forms an incompletely formed spinal cord. In the US, here are 0.7 cases per 1000 births
