Hello everyone!
I am a total noob to all of this and just joined today! I've been on this website before and everyone seems very knowledgeable and helpful. Having said that, can someone help me out with this specimen?
I tried to look this up online and ended up confusing myself. Initially I thought it may be referred to as Diplichnites left behind by a millipede, but another Google search led me in the direction of possibly Protichnites left behind by trilobites.
Is there any way to tell (if any) what this is or what could have made it?
I believe this to be from the Carboniferous, being as this was found in Beaver Pennsylvania just north of Pittsburgh in a shallow creek. I can also say from studying it that one track seems to be more like flat rectangles (trackway on the left), while the other two are more like little dots(trackway on the right. Could it be from two separate animals?
Thank you all for your help!
