  1. This was my first winter fossil hunting in NJ (or anywhere, as a matter of fact). Definitely a different experience from summer and fall. Less people, and much better fossils! Although the people I have run into were pretty devoted, which I can appreciate. Thought I would document my 4 hunts between December and this past weekend. First up, 12/16. On of my favorite Cretaceous brooks. Found an awesome variety of fossils, one of which turned out to be a Theropod tooth! Group Shot Devonian glacier erratic with Crinoids, Bryozoan and Brachiopod or Bivalve impressions. Gastropod Steinkern Ammonite Steinkern Crustacean claw piece A. phasolus Crusher Tooth Enchodus sp. Tooth w/Jaw fragment Squalicorax sp. (Crow Shark) A. kopingensis (Mackerel Shark) Theropod Tooth
  2. Otodus auriculatus Eocene Monmouth county, New Jersey In over 40 years of collecting and researching fossil, this is my finest find from NJ. Personally collected on Jan. 7, 2023.
  3. 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!
  4. Hi all, I recently came across the enigmatic taxon from South Carolina (and apparently New Jersey) - Conosaurus Bowmani. It was named in 1851 from the teeth depicted here, found in the Oligocene either Ashley or Chandler Bridge formations It was misidentified first as a mosasaur (hence saurus suffix) and had been suggested to be renamed conosaurops, but that doesn’t seem to have caught on. Only a few specimens have ever been found that I am aware of, primarily teeth and a couple jaw segments. Two of which were in a previous post by ClemsonSkulls which I was reading this morning, which likely came out of the eocene in a SC limestone quarry. I also see mentions of it from the Cretaceous of NJ. I am curious if anyone has specimens of or knows anything more about this taxon. I have located 4 references for it, including some great descriptions of its tooth shape, but as far as I can tell there have been no elements past the jaw that have ever been ascribed to this ferocious predator, and there is no clue what it is or looked like. Hoping someone knows something more! Thanks all!

    A Fish Scale From Granton Quarry

    I found this fish scale in the lighter grey layers of Granton Quarry. It is about 1 cm in length, and seems to be rather characteristic, so I am hopeful of a ID. Lockatong Fm Granton Quarry, North Bergen, New Jersey Upper Triassic Thanks.

    Monmouth County NJ newbie finds

    Hello! I took one of our kids to check out the Cretaceous Monmouth County NJ scene! It was very cold last weekend so it was a quick visit with nothing that appears too unique but hoping we can get some ID help and be better prepared for next time as we get make learn more about exploring and documenting. Thank you!
  7. Was looking for Indian artifacts in a small native undisturbed rural stream and picked up something that appears to me as a fossil. I have no experience with that kind of stuff so any help would greatly be appreciated! Thanks

    A Visit to Granton Quarry

    While on a trip in NYC, I thought it would be fun to visit Old Granton Quarry as it was close to where I was staying. In the first day, I found some nice material so I returned for another ~2 hrs on the last day of the trip. Day one was in the afternoon, cloudy but without rain. Nice conditions, and I stayed exactly 2 hours. I was fortunate to visit near Christmas, and there was little vegetation to cover the cliff-face and obscure it from view. Also there was, thankfully, no poison ivy growing. On day two, I started out early, before dawn at ~06:45. It rained slightly, and throughout the dig the cliff reminded me it was there by little bits of rock falling past my head. I found a cute little Plethodon cinereus in the cliff, before dawn, that was a bit shy. Here are the finds! Dorsal fin and some scales Partial Diplurus newarki body - caudal and anal fins - and a few ribs. Skull, and dorsal fin imprint of Diplurus newarki. Concretion/nodule - possibly coprolitic in nature Diplurus newarki - disarticulated ribs, caudal, and possible skull. Diplurus fins and scales Diplurus caudal fin imprints. Disarticulated bones/fins/scales. Diplurus caudal fin Estheria ovata Diplurus ribs Estheria ovata imprints and disarticulated bones/scales. Partial skull and ribs of Diplurus. (Possible ray finned fish scales.) Diplurus 1st dorsal fin Possible skull, or coprolitic material. Concretion nodule imprint: Probably coprolite/concretion/nodule. Could be some bone in there, as well. Diplurus caudals, scales. Possible Diplurus scales Possible Diplurus skull, and scales/disarticulated bones.
  16. Hello, am new here and need some help with these tough identifications. I have been told this is everything from a fish tooth to a mososaur tooth. Any help is much appreciated!

    Scapanorhynchis texanus?

    Hi everyone. I found this Upper Cretaceous shark tooth in Ramanessin Brook near Holmdel, New Jersey on Sunday. It is a little over half an inch wide. It appears different than any of my other Cretaceous teeth from New Jersey. My best guess- the common goblin shark: Scapanorhynchis texanus lower lateral. Most of my other goblin shark teeth (and there's many of them) are anterior and upper laterals. I do have some other lower laterals, but the blades are less slanted and taller. Still, they are the closest in resemblance. Or could it be a different species altogether? Any insight would be helpful. Thanks, and Happy Holidays! Sorry about the poor photo quality.
  19. Took a couple trips to Eocene/Miocene locations in Monmouth County, NJ. Thought I'd share some of my finds. First trip was on 11/17. Was a warm 60 degrees outside! Group shot of my finds. My first find was an erratic fossil from the Devonian with signs of bivalve/brachiopod, crinoid and Pleurodictyum. I also found this separate section of what I assume is a Crinoid stem Several bone pieces. Eagle Ray plate - my first ray plate found in NJ. Some of the shark teeth: Otodus obliquus - First time finding this species Otodus chubutensis - First time finding this species Physogaleus contortus Carcharias sp. Had to do some reconstructive surgery as it fell apart coming home.
  20. Hi All, Last week I found this Mosasaur tooth in one of the Brooks in Monmouth County, NJ (Navesink Formation - Late Cretaceous). While in the brook, a guide from the Monmouth Museum was onsite leading a small group of college students. He identified the tooth as Halisaurus platyspondylus. Had a great conversation with the gentlemen as well, so a nice bonus. Another, more experienced individual contacted me after I posted the tooth on a local FB group. He has several similar teeth, and while not completely disagreeing with Hailisaurus, suggested Prognathodon sp. may possibly be a better fit? It's debatable based on conversations he's had with other's more experienced than him. In any case, I figured there must be several Mosasaur experts on here who may be able to weigh in on the subject. Any opinions/discussion is appreciated. I'm still learning, so this is all helpful to me. Thanks in advance!
  21. Those that walk the cretaceous streams of NJ know all too well that late autumn is one of the worst times to hunt the brooks. The water becomes too chilly to sift comfortably and the ever changing gravel bars take on a carpet of leaf litter. I rarely make the hike up to the brooks this time of year, though this weekend my desire to scout a new-to-me stretch of stream got the better of me. Donning a jacket, wading boots, gravel scoops in hand off my Fianceè and I went adventuring. Navigating the brooks can be challenging in the nicest of weather but today presented a particularly muddy challenge as well. We made strong progress hopping into the stream and climbing up onto the banks when obstacles presented themselves, covering about 2 miles of stream. I used the gravel scoop as more of a rake than anything else, moving leaf litter out of the way to scan the gravel beneath. The areas we found with significant gravel banks were noted along the way and pinned on our map for the next collecting season. Finds were average along most of the trip, a dozen small/medium teeth here & there beneath the leaves. It was only towards the last leg of the trip before we turned back did I find an something awesome, an incredibly well preserved Scapanorhynchus texanus anterior - the largest we've come across in NJ. Measuring in at almost 1.8", I was very happy to see it come up after I brushed away the leaves and mud! My Fianceè and I like to play a game around who claims the largest tooth found in our collection. Prior to this, she held the position strong with a 1.56" Scapanorhynchus texanus anterior for a year and a half. With this one under my belt, I'll take the lead! Though who knows for how long Walking back, I closely scanned one of our more well known spots and came away with a small bounty - a small 0.5" crocodile tooth and a tiny 0.25" vert (likely ray/skate) On the way back to the car, we found a rather unfortunate and stark reminder of the impact we can have on wildlife as humans. One can easily imagine how this young buck met his end, caught in a soccer net from who knows where. The skull was in good shape, though left in situ for those who may enjoy collecting modern bones more than I. Finally, I can't leave Monmouth County without a short hop out to Red Bank for some of my favorite ribs! Really hits the spot after spending my energy putzing around the brooks

    New Jersey amber

    I was wondering if there are any potential amber-bearing exposures of the Raritan Formation. I understand the Sayreville clay pit site has been sold and is currently under development, and as far as I could find that was the only major location. Would there happen to be any remaining deposits between New York and southern Maryland? Most records seem to originate in the early 1800s-1900s.

    Had a Toofer Weekend

    I wasn’t expecting much from this weekend adventure, been having a dry spell with the last few hunts and a lot of misses. Gave it the good OL’College try again and oh did it pay off big time with finding not one but 2 teeth in extraordinary condition on back to back days and 2 different epochs vastly separated from each other geographically which is really cool. Time traveling but without the DeLorean! (Front and back photos of the larger tooth) 2 & 5/8 inches from tooth tip to the larger side of the root; which would be about 66 mm.
