Found this curious stone while walking a creek near Cayuga Lake, NY. My boot is shown in photos for scale and is about 30 cm. The creek is carved down through various layers of the Hamilton shale group and seems out of place. There is an outcrop of Tully limestone further upstream from where I saw this beauty but is lighter brown. I am unsure of what type of rock (Tully limestone?) it is as it was dark brown in color. I observed many dark brown boulders and slabs along the creek too. Could this be a nodule of some type and what do you think might be inside?- 4 replies

Hello, I found this rock in a creek in Hamilton, NJ. The bedrock in this area is mostly Cretaceous, but there are many glacial deposits. The part of the rock that looks like a fossil has a central line and smaller lines coming off of it, which made me think that it could be a conulariid that got there by a glacier (I'm probably wrong). Also, the side that has the fossil-like thing touches the adjacent side at almost a right angle. Can you please identify it? Thank you in advance!
