Fossiled chichen leg... possibly lower Colonel Sanders Formation.

The photos are blurry, but I'm not getting any ideas of what this could be. It might be just a concretion of limestone. They can be heavier than other rocks around them, because they are the nucleus of mineral concentration, making them heavy.

Sorry! I didn't realize how blurry they were until posted. Maybe this is better...next to cat leg. Cat uninterested so I'm inclined toward your second theory. Thank you!

Welcome to the forum 

 

Sorry I just see a concretion, no fossil

Awesome! A concretion that looks just like KFC! What's to be sorry about?! Thank you for the id...

I'm not fairly convinced of the geological status of this specimen. Maybe, it could be an ichnofossil. I think, a good possibility could be something related to Thalassionides. https://www.google.com/search?q=thalassinoides&biw=1360&bih=612&source=lnms&tbm=isch&sa=X&ved=0ahUKEwi3w-iIodvPAhXHuxQKHXO9BcYQ_AUICCgB

 

Could we have a clear view of the NR. 4 of your pictures, or other views ?
