Big brook New Jersey bone fragment ID

[Otherwiseunseen]

Big brook, NJ bone fragment find. Anyone have any ideas what part it is? Process is very porous and brittle. Light weight low density. There are 2 foramens and possibly a partial of a 3rd along the same ridge line the others follow. I tried comparing it to mammal vertebrae and skull bones. I thought the foramens would provide enough anatomy to pin point an ID but not successful. Attached are images. Please excuse the remaining purplish clay I used trying to reconstruct.
