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... -
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 all! Over the past few months I have gone down to Big Brook in New Jersey and found a few fossils that I do not quite know exactly what they are. I have a general idea on what a few may be. 1. this tooth is about 1.5 cm long and had serrations on the small part of the remaining edge. I think it is probably mosasaur but it seems a little small. It also has a small curve in it. 2. Maybe the underside of a crab? Under a microscope it is very bumpy. 3. Maybe a small scute? 4. small piece of deformed enamel from something? 5. Huge shark tooth for this area. Maybe goblin but im not 100% sure and would like a little more certainty. Thank you all!

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

A student of my found this gem earlier this month in New Jersey. My best guess is horse, maybe bison? Any help would be appreciated.

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.

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 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?

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?- 7 replies

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.

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.
