Possible Coprolite from Upper Cretaceous, Monmouth County, N.J.
Jeffrey P posted a topic in Fossil ID
Found what looks like a coprolite attached to a piece of matrix. It was found in Willow Brook this AM. Willow Brook contains exposures of Upper Cretaceous formations. It is located in Monmouth County, New Jersey. Can anyone confirm whether this is a coprolite or not and if so what might have made it. I've included views of both sides. Thank you.- 5 replies

Found this rather odd looking object in an upper tributary of Big Brook today. I have no idea if this is a fossil or not and if so what kind. Never found anything like this before. Big Brook is in Monmouth County, New Jersey. Any ID help would be very appreciated. Thank you.

Hello everyone, I normally would have posted this in one of my NJ Cretaceous Episodes but I felt this find in particular warranted its own post. This Mosasaurus maximus tooth was found on August 5th, during a 5.5 hour hunt at a New Jersey Cretaceous stream system.

Hello fellow fossil forum members this is Trevor. This is the first episode of hopefully many displaying my hunts into the Cretaceous streams of New Jersey. Within each episode there will be five stories (in this case four since I was too impatient) that are five of my hunts. I will title each hunt according to how I felt on it and I will title each episode based on my expectations or what I desire to find. Mechanized Depression (Hunt 1): Duration, 3.5 hours. My grandma and I drove up to a small cretaceous stream on April 22nd. The forecast predicted rain and the forecast was correct. While my grandma read in the car, I sifted and surface scanned and came away with a considerable amount of finds for such a short time. I almost sifted continuously throughout the entirety and it seemed as if I was working on a production line. The rain and loneliness caused the situation to feel very dreary and I eventually went back. I also had a bad blister. My best finds were a Meristodonoides sp. (hybodont) tooth and a fragmented hadrosaur tooth. It's a Trap! (Hunt 2): Duration, 5 hours. Date, April 23rd. I went with my father to Ramanessin Brook and walked for about 25 minutes before finding the spot I had sifted at a few weeks ago (where I found a decent Ischyodus bifurcatus plate). The spot yield little but I did come out with some nice condition shark's teeth. In a futile attempt to find a better place to sift I just keep digging in a bunch of random spots. I finally decided on a place and told myself that I will stay in the place till I find some good. After about 6 sifts I called my father and said that it was going really slow. He wished me luck and hoped that I find a mosasaur. I hung up and in the next sift I found a small, half inch mosasaur! I instantly called him back up and told him the pretty cool story. I stayed for a little longer craving more but I did not find anymore, well next time I said. My best finds were the mosasaur tooth and a 5.5" bone I found. Bright Exploration (Hunt 3): Duration, 5.5 hours. Date, April 29th. My father drove me to Ramanessin Brook again and I went to the same spot I had found the mosasaur. I did the exact same thing as I had done before: I dug some random holes in the stream and surveyed the area. It was after a little while that I noticed there were finds on the gravel bars. I have continually been so unfortunate as to have someone always search the bars before me. I don't typically surface scan because I never think I will find anything. This time was different and I was the first one there. I walked upstream and continued. On one gravel bar I spotted what at first I thought was a weird piece of rubber but upon further inspection I noticed it was a 3" really worn Ischyodus bifurcates plate. I was overjoyed because I had not found one this large before. After exploring a little I decided to turn back and sift some more. The day was slow other than some bones or teeth. I went back to my dad and he showed me a mosasaur tooth he had found. Since he never really searches and never really cares much this was incredible. He said it was just sitting on the surface. I was so angry for not having searched them. Well alas, it was okay. Hearing Noises (Hunt 4): Duration, 6.5 hours. Date, May 10th. I went to Ramanessin again with my father. I was really tired since within the two days prior (Mon. and Tues.) I had three AP exams that made me extremely stressed and tired. I had gotten little sleep and had not eaten breakfast. I went to where I found the mosasaur on trip two and after about half an hour I found a mosasaur tooth with about half the enamel on, okay I was confident. My confidence plummeted with time as I found less and less. There were bumps such as when I found a small piece of cartilage. I decided to move on and sifted haphazardly. I kept finding worn teeth and enchodus jaws and then I found a worn baby mosasaur. I was surprised I had spotted it. I looked in the water since the day was clear and sunny and found some nice goblins. I ended up at a larger gravel bar and decided that is was where I would spend my time. I was tired and decided to eat some food and lay down. As I ate I had the urge to roll on the gravel bar as a soldier does and I came away with two larger goblin teeth by seeing them on the ground. They were right next to someone's footprint. I thought I hear someone call my name and kept looking behind me on this ridge. Two or three times gravel sloshed into the hole I dug and made me jump; I thought someone was behind me. After this I decided to leave. At the end I found a really nice Xiphactinus tooth and a really worn mosasaur tooth. Trip four is on top and trip one is on the bottom.
