Pit 11 Poychaete Identification Help

Hi all,

this is one of the polychaete worms from the batch of Pit 11 concretions I'm working on. From what I can see of the conical jaws it most closely resembles Didontogaster corydylina but the jaws blend a bit together and aren't as distinct as some other specimens I've found. The body profile seems a little off (no swollen front section for one) so I wanted to ask for second opinions. Am I getting too hung up on the profile of a body that could just be more outstretched?

 

I appreciate everyone's thoughts.

I believe this is an example of Dryptoscolex.

They are quite rare. 
Can you try to get some clear close up pictures of the jaws?

Very nice find!

Here are some pictures I took experimenting with a macro lens and a regular camera through a loupe. The first two are of what we will call the positive and are more defined than the third picture which is the negative. I might be able to get better photos using natural lighting tomorrow. After these pictures I can see that it seems more like Dryptoscolex. I have another worm from this batch that I ID'd as Dryptoscolex (the jaws are large and almost pendulous). I'll post that one as well for a second opinion now that I know they're rare.

 

Thanks for your help.

Here's the other worm. The body isn't great but the jaws are quite nicely preserved.

@RCFossils Here is a better focused image I took using a macro lens. Between this and the previous images it gives a decent picture of the curvature of the jaws. What do you think? Do you think the other worm is also Dryptoscolex?
