I found this fragment of jaw from what I believe is a beaver yesterday at Big Brook in New Jersey. Could it be pleistocene or just iron stained modern bone?

Mammal incisor (?) Found at Big Brook, New Jersey - any chance it's pleistocene?
TRexEliot posted a topic in Fossil ID
I just found this earlier today. It's so hard for me to judge age on mammal material in Big Brook because it stains so quickly...

Usually, I wouldn't ask about anything quartz from Big Brook, since I've never heard of any fossils there being agatized or any other type of quartz preservation, but I found two pieces on my most recent trip that have me really confused. The first has lots of wrinkles and folds with tiny open pocket structures that are growing druzy crystals all over in a pattern that looks like some agatized corals I've seen. The second has no openings or druzy, but has the same soft folding texture and looks almost exactly like a shriveled plum, with an incredibly soft, velvety texture on both the high AND low points of the surface. Are these just weird rocks, or could there be something more going on here?

I found this small and delicate, nearly intact marine reptile bone in Big Brook yesterday, and I'm wondering if anyone can identify it. The bone is just under an inch in length.

Fossils or just interesting concretions? Found in Big Brook, NJ
TRexEliot posted a topic in Fossil ID
Ordinarily I would throw something back if I didn't have at least a tentative ID when I saw it or some strong reason to believe it's a fossil, but this I really wasn't sure about. I have no idea what they might be, but I had never seen a concretion quite like them before in the brook, and I found it even more bizarre that I ended up finding two of them. Any thoughts?

The first of these (the dark black one), I found last year and I was told by Dana Ehret of the NJ state museum that it was most likely a fish scale fragment, and that it could possibly be from a gar. After looking up gar scales, however, it has never seemed like a perfect fit for the shape. A few days ago, I made a trip to the brook, and found the second tan specimen. The pattern in the enamel looks very similar (though not identical) to the first, so I thought this could be another fish scale. Since I hadn't adequately satisfied my own curiosity about the exact species of the first, I figured I'd post photos of both and see what people think.

Hi all, These fossils are from a trip I recently took to Big Brook, NJ (Cretaceous, Monmouth Group) in March. I also found a great mosasaur tooth and a beaver tooth on this trip, which I've posted elsewhere. I know this lot is a bit random, but I'm hoping there might be some light shed on them. I'm especially curious on the ridged appearance of #2. For #6, I know they are all small bone fragments. Is there any way to tell dinosaur bone from aquatic reptile bone? For #7 I admit I'm not sure if it's a fossil or just a neat concretion. Thanks to any help! Chris

Fossil clam found at Big Brook - first of these I've ever seen, is it anything interesting?
TRexEliot posted a topic in Fossil ID
A bivalve fossil I found at Big Brook yesterday. First one like it I've ever seen, so thought it might be something interesting.

After great input from the community, the tooth is likely a Plesiosaur and not Mosasaur. Thank you everyone! For my birthday last weekend, my girlfriend and I returned for our second trip to Big Brook in New Jersey. I couldn't have asked for a better day. We came into the day joking about finding a Mosasaur tooth for my birthday... well.. the luck of the Irish was on my side. Braving the still frigid water and sub 40 degree temps, I was rewarded with my first ever Mosasaur tooth. I would also like confirmation that it is Mosa and not crocodile. Unfortunately it is not whole, but it is rather large, and I couldn't be happier. In total we found around 111 teeth and some other non teeth related fossils. Most were shards, broken, or unremarkable but below are the complete and nicer finds of the day. Thanks for looking and any comments! Shoutout to the Philly Fossil Collector on instagram for helping me with ID and advice! I don't remember your username on here though! Partial Mosasaur tooth: Any information known on my specific find, I would absolutely love. Overall complete and nice finds of the day (Me). Partial Mosasaur tooth Shark teeth: Crow, Goblin, Mackerel. Any others? Shark Vert? Enchodus teeth (2) Pycnodont Fish Crusher Tooth Chunk of obsidian/phosphate? Ill have to follow up with some pictures but when in the water it had streaks of gold like pyrite. Shark Vert? My girlfriend found this one, would love confirmation on what type of vert. Check out the coloring on this beautiful tooth. This is the smallest whole tooth I've ever found, anyone know the ID? 18206F19-E91F-40B7-BCD2-82154A49D0D5.mp4

I just returned from a few days up in NJ where I had time to visit Big Brook (and Ramanessin for a little bit too). I went for a couple hours last Wednesday when I first arrived, then picked up where I left off Thursday morning. It was pretty chilly. About 28 degrees when I first woke up at 7. So I did some other work at the Colt's Neck Inn Hotel (highly recommend) until about 11. Over that time it warmed up almost 10 degrees. But I headed out. The positive to the cold weather was that I was the only one out there. It was also sunny despite the cold, and was otherwise a great day to go out. About 2pm and nearly to the Boundary Rd bridge, sifting through pile after pile of gravel, this beauty rolled across my sifting pan and I could hardly believe it. After a good 5 years and several trips, I finally found my first mosasaurus tooth! It's a bit beaten up and chipped, but I couldn't have been happier. Totally worth my beet red hands. This was my big trip maker and will have an honored place in my special fossil cabinet.

In NJ for the next couple of days on business and able to make a side trip to Big Brook today. Among the usual shark teeth, I found this mammalian tooth. It most closely matches some photos of Pleistocene age beaver teeth that have been found. Is that what it is most likely or could it be another mammal? Apologies for the photo quality, I'm still on the road and did my best.

Hi all, I found this at Big Brook in NJ (late cretaceous) a few months ago during one of my trips. I recognize it as a vertebra, but not like any shark or fish vertebra I've found before. Any ideas?

Hello! I have been getting a lot more into rockhounding and looking for fossils recently. I've been able to identify a bit on my own, but I have some from last year that I'm really not sure about. This is part of what I've found, I tried to sort them by similarities. The only spots I go to are im central jersey - watchung, big brook, and sea girt but I believe these are all from the brook. Thanks for any assistance! Also, I just learned about rock decay as I was putting this together and that might be 4 and 5, and the last two have been identified (Fossil #16 is a Pycnodont pharyngeal tooth and Fossil #17 is part of a crab claw?)

Hi all, I just got back from my first Big Brook journey and found many amazing things. I've figured out the majority of my finds but i am left with a few below that i could use some help on. I've attached pictures with measurements. Please let me know your thoughts! Once I've IDd these, i will make a post of my findings in the sites forum. If some of these chunks are too small to identify, i completely understand. Location: Big Brook Preserve, New Jersey. Found in creek from various methods of sifting and surface scanning. Period: Cretaceous, 70-72 million years old 1. I believe this is my first shark vert but would like confirmation. 2. These types of rocks were plaguing my new paleontologist brain all day. Can someone confirm what type of rock this is? This is NOT a fossil correct? My gut and from what I've seen is telling me ironstone concretions (The bane of New Jersey)? Two examples here: 3. Absolutely no clue, don't believe it is a rock though. 4. Bone? Is this enough to ID? 4. I thought these were plastic chunks at first. The brown one is definitely not though. The black cone has two perfectly symmetrical lines going up either side, seems odd. Doesn't sound like plastic when tapped though. Thank you in advance and please forgive my ignorance, very much a rookie at identifying anything other then teeth!

Hi TFF, As the warm weather collecting season winds down, I found some time recently to snap some photos of finds from Ramanessin brook over the past few years that still give me pause, would appreciate help nailing down some IDs! Photos below, most edited to be brighter and higher contrast I believe this is a shark coprolite based on the "acorn" shape I've debated on this being plesiosaur or crocodile for a while but do believe it being plesiosaur given pronounced striations, lack of cutting edge and the conical U shaped root present in the second photo In contrast, I believe this to be crocodile This tooth in particular has stumped me for a while now, I have not found another like it but believe it to be a sand tiger shark (Carcharias holmdelensis) This I believe to be pathological of some sort These two, I'm thinking Enchodus Finally, the mysteries - I have no clue what these could be! Mystery 1 Mystery 2 Thanks!

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!

New Jersey - Big Brook - Higbee Beach Loop Trail - Elsewhere?
Toothie posted a topic in Fossil Hunting Trips
Hello, My work is sending me to New Jersey towards late September. This might be a once in a lifetime search, so I want to make the most of it and I'm hoping my fellow members can help. I did some research and wanted to know your thoughts on these places: Big Brook - I love searching for any fossils, but I really want to find a Crow Shark Tooth. I know I'm limited to the number of teeth I can find here. Would this be a good place to search? I know Septmeber isn't ideal, but this is the only time I can get out here. Does the tide vary greaty each day or is it fairly consistent? I've never found a Native American point and I don't care if I can't keep it, I just want to take in-situ photos of them. I've literally been dreaming about finding them a couple of times a week for the past several months. I read that Higbee Beach Loop Trail might be good for that, but again, I'm not sure if September is good. I only have 2, maybe 3 days to search, depending on what my fellow forum brothers and sisters tell me. Any other places that are better than these? Should I avoid these areas? Any help is truly appreciated. I'm not asking for any honey holes or private spots, even though people have shown me places in other states and I've kept those secret for years and I will never tell. Just friendly advice is truly appreciated. I'm going to Maryland too, but I'm all set there. Have a wonderful day! -
Folks from New Jersey and Pennsylvania, Did You Have Any Good Fossil Hunting Trips This Past Summer?
Suchascenicworld posted a topic in Fossil Hunting Trips
Hey everyone, I live in Southern New Jersey and while I usually spend several days fossil hunting, I unfortunately, did not make it out (yet!). I usually go to Big Brook, and hopefully I will make it there in September. In the meantime, how was everyone else's summer in regards to fossil hunting? Any interesting trips or finds? Hopefully your experiences can encourage me to get out there quicker! :-) -
For the first time in a while we were able to visit Big Brook for some hunting. To start with it appears that Big Brook is now one of the Top 5 weekend destinations in NJ so we had to wait 30 minutes for a parking space to open up. But we headed up stream where most newcomers don’t venture to. Good day but nothing out of the ordinary. Decent teeth, some nice bivalve impression fossils, fish verts and the common belemnites. what’s the rectangular item with the “X” across it that’s seen in the last image?

Hello, I found this interesting fossil fragment with what looks like serrations at Big Brooks a few days ago and was wondering if anyone could help Id it.
