Okay so I found this specimen at the Taughannock Falls in Ithaca New York.
I found it at the edge of the gorge which consists of shale, composed of slit and clay that fell onto lime mud and hardened into rock.
I've done some research and it appears to be a Brittle star trace fossil formed by their arm grazing the sand floor.
Although, these Brittle Star fish traces are known as "Pteridichnites biseriatus" and they have only been discovered so far in upper Devonian shales out in western and eastern Virginia. I'm not an expert but to my knowledge the Ithaca geological formation is Devonian and was slowly covered by sand.
Is it possible that the Brittle Star fish once roamed in the ancient sea now known as "Taughannock falls" today?
Because a research team is trying to find this specimen and they are wondering if anyone has discovered it.
