Xiphactinus Or Enchodus Id help - GMR NC

[AshHendrick]

Could someone assist in determining if these two items are an Enchodus or Xiphactinus? I found the larger one this past Saturday and the smaller one a few weeks ago, same general area at GreensMill Run in Greenville NC. Found these among whale bone, great white, tiger and crow shark teeth and a couple sharks of likely mastadon tooth - obviously a nice mix from a huge time span. I assumed enchodus until a friend mentioned the Xiphactinus, which I didn't even know was an option yet, so I would also appreciate detail on how I can discern between the two in the future - characteristics etc. 

 

 

1. 

 

2.

 

 

 

and I also have several of these, ranging in size/condition some with enamel etc - this one as I'm taking photos I realized the tooth part of it might not actually be what I was thinking for this one, but the rest have the more rounded tooth, anyhow, are these jaw pieces with broken teeth like those above to be identified? 

[Fossildude19]

All Enchodus,  I believe. 

The last ones are a palatine fang. Just rounded and worn. 

I think the first might be an intact palatine fang.

You are correct as they are both Enchodus...pretty nice examples as well!

I also see only Enchodus.

Those appear to be very good and typical examples of enchodus fangs- just like the ones we find in the Cretaceous of New Jersey.

The first one reminds me of a broken shark tooth such as a sand tiger or goblin shark.

Those all appear to be nice examples of Enchodus.  Preservation is different in different areas, but speaking for Kansas, X-fish teeth are super rarely found that are already exposed.  (The same is true for mosasaur teeth here) 

Almost all examples of X-fish teeth I have are in jaws that I was able to dig up.  Those X-fish and mosey teeth around here crumble quickly when exposed.  Enchodus teeth must be much more stable, as they can be found much more frequently.

Thanks every one.

 

Rick, I thought that initially when I first pulled it out of the screen, which would have been a decent sized one, but there was no sign of root breaking off and then when I got it home and compared it to some of my really nice quality sand tigers, the flat edges are different in positioning on the tooth so I figured it's probably not. we may never know the truth  

 

Ramo - I'd give about anything to be able to go digging somewhere that I could find things like jaw bones with teeth still in them!!! I LOVE my finds I get right now, of course, but not sure how I'd manage to keep my cool if I came across something like that!

Standing with everyone as being Enchodus, but im only 100 percent firm on the second tooth. As you can see, the tooth is generally flattish on the bottom, but on the top, the base is very tall, which curves down, then up a little, then finally doen to the tip. I usually identify this trait that of Enchodus. Xiphactinus usually have conicalish teeth, if Im correct.

Hmm, not convinced on that first one. I'd have to see it in person but based on picture I am sticking with a shark tooth missing most of the root.

All Enchodus

[Xiphactinus]

100% all enchodus

[AshHendrick]

ALL ENCHODUS!! (we are chanting, right?)

[frankh8147]

Enchodus it is, and a nice one at that! Here are some examples I found in Jersey for comparison.
