PA Ordovician Unknowns - ID Help

[historianmichael]

I recently collected these three fossils on a trip to the Salona Formation in Pennsylvania. I was able to identify everything I found except these three. Any help would be greatly appreciated.

 

#1 - initial thoughts were Cryptolithus genal spine but it seems very large for Cryptolithus and I did not immediately see the pits that are normally associated with Cryptolithus

    

 

 

#2- perhaps some type of sea plant?

  

 

 

#3- no idea. It reminds me a little bit of Tentaculites. It measures about 1 cm in length.

I'm not entirely sure but I'll take a stab...

 1 is Cryptolithus perhaps ventral or worn.

2 possibly Chondrites

3 Cornulites

I would love # 3 to be a piece of carpoid!

Maybe someone can rule out or in?

# 3 looks like a possible graptolite, to me.

Thank you all for your initial thoughts. I also initially thought that #3 could be some type of graptolite, but the fossil is 3D and comes out of the material. It also lacks the "pencil mark" appearance.

 

Here is a further image of #2 further zoomed in. Please let me know if you all would like another photo. I am not quite sure it matches the solid burrow appearance of Chondrites. It almost looks like a trackway with how disconnected the lines are, but the orientation of the lines do not match any trackway I have seen.

I am going to say that number 3 is a bryozoan.  Something similar to one I have. http://www.crinus.info/otherfossils/data/trig.htm

 

Close up pictures would help to see the details for both 3 and 2.

Three Dimensional graptolites are not uncommon in some areas, just FYI.

@Fossildude19 Fascinating! I did not know that. Perhaps that adds more credibility to it being a graptolite of some kind then.

 

Here are some additional photos of #2 and #3. It is tough to get a crystal clear, zoomed in photo since I am using my phone's camera. I take back my comment about #2 being disjointed. The lines actually appear to connect. They are just very thin.
