Are all of the teeth vetus? Or is audax also in NJ?

Check out the two Xiphactinus in this thread. Are they audax?

I am confident those are both X. vetus. I heard all the Monmouth Co. ones are vetus. Audax might exist somewhere else in NJ, but I don't know.

I am pretty sure that audax exists in NJ. I need to do some more research though because I thought the one I had was audax not vetus.

Some links for comparison:

It is possible that audax exists here. Some teeth are definitely vetus, but others are questionable. The smaller one that you have on that link is definitely vetus. Not sure on the other one.
