Good evening folks! I’ve had this specimen in my collection since April 2013 when I first visited Big Brook in New Jersey. I have a separate fossil from the same trip that I am more thoroughly convinced is bone which is highly dense and has probable scavenging marks. If it is a fossil then a more reasonable answer may be burrow cast. I may have slight delusions of grandeur with this piece, but I think it’s worth discussing!

My past two trips to Ramanessin Brook in Holmdel, NJ have been especially productive. Resulting in much larger teeth and much more diverse finds, Ramanessin has proven to be a much better spot than Big Brook for me. Here are the finds from the first trip: Many large anterior goblin shark teeth; a very large crow shark tooth; some very nice mackerel shark teeth; two pycnodont teeth; coral; a large ghost shrimp claw; a large ammonite fragment; a scallop with both shells intact; what I believe to be a fragment of a very large sawfish tooth (though it does seem especially striated for a sawfish) Finds from the second trip: More large goblin shark teeth (one pathological); another large crow; some very curvy mackerel shark teeth; small shark vert and a fragment of another; some sort of bony fish jaw; various sawfish crowns; a beaver tooth (more insight as to its age would be greatly appreciated); two Gastropod molds; ratfish jaw; I believe the two large fossils to the right are a coral imprint and possibly a lobster claw another pic of the beaver tooth; it seems hollow inside chewing surface seems worn; leads me to believe it is a modern adult beaver tooth up close pic of the lobster claw; noticeable “dots”

I have been fossil hunting in the Monmouth County, NJ area for quite a few trips now, and I have accumulated a good amount of fossils I haven’t been able to ID. Here are some of them: Note: feel free to ask for more angles; I didn’t want to post too many images. 1 inch for scale Found in Ramanessin - no idea what it is Found in both brooks - 5 in middle look to be same species; I believe far-right is pycnodont or hadrodus Left - found in Ramanessin; think its coral Right - found in Big Brook; thought it was coral when I found it but I’m now leaning toward coprolite Both from Ramanessin; Left seems to be an imprint from some sort of spine; My father thinks the one on the right is some sort of crinoid Both found in Big Brook; Possible reptile teeth; maybe mosasaur or croc, though they are very small Found in both brooks; left seems to be a possible Pachyrhizodus; all have distinct carinae Found in Ramanessin - potential hadrosaurus tooth fragment Thanks in advance for your help!

Found this in Big Brook, NJ (Late Cretaceous Navesink Fm.). It's about 2.5 cm wide. I don't even know what phylum to put it in. My first thought was bryozoan. There is one very thorough paper on Bryozoa of the Atlantic Coastal Plain, but it has nothing to fit the bill. Looks like sponge with those big holes. Found a picture of Discopora sp. that looks very close, but that genus is not listed in PBDB anywhere in North America. Gabb thought he had something similar from NJ, but it turned out to be a sand concretion. The last picture is the underside of the specimen, which may or may not be a thin layer of shell material from a bivalve.

Hello Fossil Folks.. Wondering if there is enough here to make an identification. All items were found in NJ along the bays of the beautiful locale of Monmouth County. Most everything I pick up is very sea worn, however, a lot have similar form and are the of the same texture. Many remind me of little tree trunks, some are flat like the ends of a paddle with a little curve, and few are round like fingers. Other finds I can easily id, like fossil clams and coprolite, but these I’m curious to know what they might consist of, or what they may have originated from. Maybe they aren’t even fossils. What I do know is that they are unique in that I have never found anything like them in the cretaceous brooks. So here goes, I did my best with the pics. Another thing that makes it hard to id stuff is that most everything is the same black or brown marl color. Thank you!

Hello everyone! In the last month, I found two interesting Mosasaur teeth in two very different locations so I figured I'd share! For the first, I was digging in the basal Navasink in Southern New Jersey (primarily an invertebrate location). In the matrix, I happened to see a tiny bit of this tooth sticking out. As this is my only Mosasaur tooth in matrix, I prepped it so you can see the tooth better but left it in. The second is from my usual location - Big Brook. Nothing unusual there however; it does happen to be both my longest and widest Mosasaur tooth! Its under two inches but has some serious weight! The last picture is of my Mosasaur collection with my new editions in it

Hi everyone, I was wondering if you could help me out with something here. I found this piece of ammonite at Ramanessin Brook (whole piece is about 6cm across). I initially thought it was some sort of internal cast of a gastropod but when I noticed the suture patterns I realized it had to be the inner whorl of an ammonite. However, I'm perplexed by the texture of this piece. Parts of it displays an almost "scaly" pattern which I've never seen before. Any ideas what could have caused this? Thanks! Some closer images of the texture:

Hey all, I found this in a South Jersey creek gravel bed. The particular spot is in the Navesink bedrock formation, but I'm unsure of how exposed it is (if at all.) I haven't found much in the way of fossils in this particular spot except a possible burrow and a possible oyster shell. I initially thought it was an odd looking concretion, but I cleaned it up and had second thoughts. It's extremely porous (passed the tongue test), which made me think bone. It's also very heavy. Please let me know if more pictures or information would help. Thank you in advance!

I recently found this really cool double Agerostera mesenterica at Big Brook in New Jersey (Late Cretaceous; Navesink Formation). After I finished cleaning the fossil, I noticed these tiny encrusters on the larger of the two oysters. They don't look like your typical Serpula tube worm trace. I am not quite sure what they are. They almost have the shape of being some other type of bivalve. Any help is greatly appreciated. Some close-up photos using my digital microscope

This specimen comes from the 1980 dredge spoils of the C and D Canal. The type specimen for this species comes from the Navesink Formation exposure of the same canal, not far away. Known by locals, it was not actually described until 1986. Although not the most common of species at this locality, and almost unknown outside of Delaware, these miniscule urchins were nonetheless plentiful at the Reedy Point spoils. Recent excavation for barrow removed most of the sand where my specimen was found.

The treasure of the Reedy Point Spoils is in the micros! This is one of over 100 micros I collected in one day just surface collecting after the spoils area was freshly cleared of vegetation -- and freshly cleared of much of the remaining matrix. Of all of those micro fossils, this is the only one of this species and very possibly the only one I have found in 16 years of collecting at that site. The Reedy Point Spoils is a 220+ acre dredge deposit from the Chesapeake and Delaware Canal. The matrix is a combination of material from the Mt Laurel and Navesink Formations, which are not exposed in Delaware, but are on the surface in their namesake towns in NJ.

Dear Fellow Forum Members, On this day, the 4th of October in the year 2020, @itsronni @Masp @Trevor and @Jeffrey P ventured to a frequented late cretaceous stream in New Jersey. I first met up with Jeff and did some sifting before later locating itsronni and Masp further downstream. Finds came somewhat slowly after we first stopped to sift but after some time we gradually found more fossils. We stayed in one area for the majority of the day up until Jeff had to leave. After some deliberation, the remaining members and I walked a quarter mile upstream and then left shortly afterwards. It was a nice day to meet fellow forum members and also a nice day to collect fossils. Here are my finds, the others will post theirs when they can:
