bone fragment

[Spinosaurus]

i have this bone for a long time now, but i never realy knew what it was. i think it could be a unla fragment but i'm not sure.

i hope maybe someone will know what it could be 

and the place where i found it was at Maasvlakte 2, the netherlands.

I cant say much, but I can say that thats probably the upper joint part of an ulna, with some parts opposite of the semilunar notch having been broken off. 

 

Also you spelled ulna wrong. You said unla
