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 thi

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 fossi

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!

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

Hey everyone, newbie here, coming to you from beautiful Camden County, New Jersey. I was incredibly interested in paleontology as a kid; I was lucky enough to to go out west to Dinosaur NM, Como Bluff, Fossil Butte, etc. Pretty sure I went to Big Brook too, I remember finding some sponge bored oyster shells and not much else. But that interest faded as I got older, as most childhood hobbies do. Fast forward 30 years, I got Covid last December and spent a month on the couch. With endless time on my hands, for whatever reason I stumbled upon Mindat.org and started looking at local

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 no

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 afterwar
