Found these teeth in Big Brook,NJ today. First one I’m sure is a mosasaur but I’ve no idea on the second one. Thanks.

Big brook, NJ bone fragment find. Anyone have any ideas what part it is? Process is very porous and brittle. Light weight low density. There are 2 foramens and possibly a partial of a 3rd along the same ridge line the others follow. I tried comparing it to mammal vertebrae and skull bones. I thought the foramens would provide enough anatomy to pin point an ID but not successful. Attached are images. Please excuse the remaining purplish clay I used trying to reconstruct.

Hi. I found this tooth today and it looks like it has worn down serrations. I was wondering anyone can help with the ID on this. @The Jersey Devil

I just took my friends out for a fossil trip their first time yesterday; where we could all get together and do something cool and introduce them to the fun pastime and interesting research I dabble in for my birthday. I should’ve known he’d have beginners luck but I was not expecting this find when he plucked it out from the water. They all had a blast and it was a beautiful day. Any and all input into trying to discern what creature it could’ve came from? The more the merrier! A couple other angles

Hey so a few days ago I went to Big Brook and found a few dozen teeth along with some ray teeth, gastropods, and fish teeth, and these are my questionable specimens. IDs would be helpful! I'm thinking 1st is enchodus jaw, 3rd is some fish crusher tooth, 6th might be a fish jaw or bone material, 7th is possibly an enchodus jaw, 9th could be a scute or bone material, 11th looks like half a ray tooth. But I would like other people's opinions too on my finds. Thank you! Also I am pretty confident on this being a reptile bone but also want an opinion on it

Found this large vertebra in Big Brook 7/24/21. Measures 1.5” x 1” x .5” In the last picture it’s next to vertebra I usually find for size compassion. Any ideas? Thanks.

I ventured to the NJ brooks last weekend and made it to both Big Brook and Ramanessin Brook (Cretaceous, mix of Navesink and Mt. Laurel formations I believe). I found a few goblin and crow shark teeth, but need some help with ID for a few other finds. Thanks in advance for any help! Here are some detailed images of each. #1: concretion, or tooth? #2, definitely looks like a vertebra, but for a fish or shark? #3 also looks like a vert, or is it another concretion? #4: I found a few like this, but can't tell if it's just a weird concretion or some kind of plate or scute? #5 Looks like something in matrix #6 looks like some kind of small reptile tooth to me. It's a little hard to tell, but it does have a worn enamel appearance and some worn ridges on two sides. #7 of course is a pretty large shark tooth, but it's a bit worn and hard to tell from what genus/species. Looks a little like a goblin, but the base near the root is so wide. #8 might just be a concretion, but it did have a terestrial animal tooth appearance to it #9 looks like a tooth, but I can't place whether it's a fish or reptile? #10 looks like part of a vertebra? #11 looks like part of a plate or reptile shell? And last #12, pycnodont? bone?

Hello all! After a long time away, I managed to get myself down to New Jersey to fossil hunt! Sadly, it was this last Friday, and over 95 degrees, so I was not as productive as I had hoped, and spent a lot of time sitting on my butt, boots in the water, just kind of vaguely looking around. (If anyone was suffering there with me friday, i was wearing a barfing t-rex shirt and was probably alarmingly pink in the face). However, I got a passable haul of shark teeth, belemnites, and quite a few dunnos! The larger one in matrix i suspect is a crustacean claw, the weird conical one maybe a weathered internal cast of a gastropod (it has some vaguely spiral markings on it), the holey one maybe part of a hybodont spine? The smooth curved one has zero distinguishing features and does not appear hollow but is extremely smooth and dense. The tiny cone is perfectly conical, not a pinched oval. The curved bone- fish jaw? All assistance appreciated! The scale is one inch.

Hello, below are photos of some verts I found at Big Brook Park in Marlboro NJ. (Late cretaceous, Mount Laurel formation). I thought they were both ray verts, upon taking another look however I noticed there are some slight differences in their build. I wanted to see if anyone had any clarification for me. I've checked the usual sites, njfossils.net and njfossils.com, but I think I don't know how to interpret different features. I took photos of each face (anterior, posterior),and tops and bottoms (dorsal/ventral sides). Both were found, to my knowledge, in the Mount Laurel formation at Big Brook. I also tried to take a close up of what appeared to be spinal process attachment points on the smaller vert. Aside from one vert being more oval than the other, the larger seems to decrease in surface area/diameter from anterior to posterior, while the smaller seems to form a wedge or "v" shape along the dorsal-ventral axis. I tried to capture this in the photos but I'm limited by my equipment. Ultimately, I'd like to confirm if these are both ray verts, or if either come from anything else. Thank you, Pic A (possible process attachment points on small vert): Pic. B Pic. C Pic. D: Pic E

Anyone have any ideas what this might be. Found in Big Brook, NJ 7/16/2021. Approximately 3/4” x 1/2”. Thanks

After seeing all of the interesting things people had found in Big Brook NJ i looked through my unknowns and thought I would ask for help. If I had found the fossil in A and B in florida I would have called it worn dugong rib. However I dont recall dugong coming out of NJ therefore I dont really know what it is, ?wood? The next set are a couple of pieces that may be sandstone, or ironstone, or maybe fossil unknowns. they all have a mild c shape, oval shape with layered central depressions. they were similar enough for me to keep them but i dont even know if the all or any are fossils . c and d are off color beleminites to suggest that some fossils coming out of this area can have an odd color and surface texture. There are alot of people on the forum who hunt this area regularly, please take a look and help me understand what I have found. thanks Excel.lnk

Hello guys , I found some bones in big brook (Cretaceous fossiles), nj and I don't know if they are modern or ice age. I also added another strange fossil I found but can't id

I found both of these a couple days ago on my last trip to Big Brook in the same pan, and both have a very similar texture and appearance that leads me to believe they could have belonged to the same animal. I shared both via PM with @Trevor, who suggested the vertebra was likely Mosasaur (but that it might have a diagnostic ID), and that the bone was some type of marine reptile. Just thought I'd re-post here in case others might have any thoughts to add to that. Also, if either is worth taking in for a more diagnostic identification, where/to whom should I take them? I have heard there is a museum that most people take their big brook finds to, but I have never been there and forget which museum it is. @frankh8147

Big piece of petrified driftwood and possible fragment of pet wood from Big Brook, NJ
TRexEliot posted a topic in Fossil ID
The first is a large piece of petrified driftwood I found in Big Brook a couple years ago, the second is a fragment I am trying to ID. I noticed that the grain texture on the fragment looked like the wood grain on my piece of petrified wood, so I am trying to figure out if it might be petrified wood as well. Thanks! @Trevor

I've found small pieces of delicate jaw bone with teeth at big brook in the past, which I believe to be enchodus. This one looked like a much more heavy duty version of the same, so I was wondering if it might just be a larger specimen of the same species. I've photographed it next to one of the smaller fragments of jaw just for comparison. Thanks! @Trevor
