I have posted three series of photos on zoobook and would be grateful for opinions
This seems to be a spinous process from a large mammal.  From the sides
you can see that there is additional bone growth 1/2 way along, and that when viewed from the caudal end, the process widens out at that point.  Injury? If so, soft tissue?  Or could the process have been broken and healed? Infection?  Any thoughts welcome.

see other emails for the other bones (to keep the threads sensible)
