Clear Fork Ichnofossils

[TyrannosaurusRex]

Howdy folks! I’m back for some more identifications, again.  

Theres not a lot published on my area for tracks/Ichnofossils, so perhaps someone here has seen something or knows what some of these might be. 
 

All are Clear Fork Permian from Abilene, Texas. 
 

Potential Arthropod?

 

 

Track, potential Laoporus?

Really odd, could be from an animal or might be something else

 

Another oddity. Water droplets?

Tetrapods, potential Laoporus or other. 

 

Thank you all for any insight! There’s just nothing published about this specific site so it’s been really tricky for me to identify things.

Gee I'm sorry, but I'm afraid there may be a good reason why you can't find publications. I'm not convinced these are tracks.

Thank you for your thoughts. I’m not convinced either that most of them are. However, the one in the last reply most certainly is, I’ve already had my professor take a look at it and he agrees. The issue in publications arise from the fact the area has not been studied previously.

The little bumps are somehow arranged in rows. I don't think they are water droplets.

@Wrangellian pointed out that they could possibly be some sort of bark in my fossil hunting trip post. They’re mighty peculiar for sure. The inner raised bump inside each spot is baffling.

After lots of digging, I found a paper written on an area close by to where these pieces were found. 
 

This piece is from a burrowing water arthropod named Rusophycus carbonarius. 

 

See figure D

I'm really not sure about bark for those drop-shaped things. It was just an idea based on their regularity. Rain drops are quite random. I do see trace fossils here so maybe they are another form of trace fossil?

Note: Rusophycus is the ichnogenus name, applied to the trace itself, not the critter that made it. Trace fossils are given genus/species names like body fossils but in most cases no one can say for sure what critter made a given trace. Rusophycus is thought to be a trilobite trace. I'm not sure I see any obvious Rusophycus in your lot, though. Is D in the figure supposed to be Rusophycus?
