Hello, I am new here (sorry if I did something wrong or something I shouldn't have) and I am volunteering at a geology museum and I was given this cast of a fossil to look at and see what it was by a visitor. The visitor told me she got it as a gift and she does not know where it came from, nor does she know what it is. I was wondering if anyone here might be of some assistance in figuring out what it might be? I think it is some sort of Coelurosaurian (maybe a primitive bird?). Unfortunately I do not have any more or better pictures available right now. I could get some more pictures, but I'm not back at the museum until next week so it will take a few days. Also the cast is about a foot long (give or take about 2 inches).
