  1. Coprolite faker?? New Jersey

    Hello! From the Cretaceous of Monmouth County New Jersey, I found what looks like a big, steaming...well, you know! The thing is though, it does not resemble any spiral coprilite I've ever seen so I'm wondering if it's from something else or just a faker! Thanks!
  2. New Jersey Cretaceous bone

    Hello! I recently found this in a Cretacous steam in Monmouth County NJ. I've found a good amount of Mosasaur bones in this area so I was wondering if this can possibly be identified or if it gets the dreaded 'chunkosaurus' label. Thanks everyone! Note: I'm not sold that its Mosasaur, but for some reason, in this area, I do find a lot of Mosasaur bones.
  3. New Jersey Cretaceous tooth (croc?)

    Hello, I found this little tooth yesterday in Monmouth County New Jersey. It has two really well defined cutting edges and is heavily faceted. It doesn't look anything like the other Xiphactinus teeth I've found so I was thinking croc (not Thoracosaur)? It really looks like an enchodus tooth but the root says differently. As always, all help is greatly appreciated!
  4. Hybodont?? New Jersey Cretaceous

    Hello! I originally thought this was a Hybodont shark tooth when I found it (size is perfect) but I just realized that no other Hybodont tooth is my collection is curved like this. Is this possibly from a different part of the mouth or did I completely mid-label this one.. As always, all help is greatly appreciated! @Carl
  5. Belemnite with bite mark?

    Hello! I found this belemnite in Monmouth County, New Jersey. I try to be careful with labeling 'predation marks' on fossils but knowing how these break, it's tough for me to picture this occurring after death or during the fossilization process. What do you think? As always, all help is greatly appreciated! -Frank
  6. Hello! I just wanted to check on these two pieces before they go into the black hole known as my 'unidentifiable bone' bin. Both are from Monmouth County New Jersey (Cretaceous). I found fossil number 1 two days ago and unfortunately, it didn't make the trip back home in one piece. When I looked at it though, the broken sections looked more like my broken Mosasaur and Enchodus teeth than bone (scan below), and it also reminded me of a fossil my brother found years ago that we weren't able to identify. I looked online and the texture of the recent 'thing' looked similar to some dinosaur teeth (Titanosaur and sauropod especially) so I just wanted to see what everyone thought. Thanks again! -Frank
  7. New Jersey Cretaceous help

    Hello! I have two fossils I found in Monmouth County, NJ, I would like to get some opinions on. The first one looks a lot like my other Mosasaur Verts (concave on one side, convex on the other, size and shape look right) however, it has that divot on one side so I was wondering if that could throw croc into play. The second one, which I believe to be reptile bone, has those four equally spaced lines on it so I want to know if we think they are predatory/scavenge marks. I know that's usually tough to tell but that spacing between them looked pretty good to me. As always, all help is greatly appreciated! -Frank H
  8. Big Brook Finds!

    Hi all here are some finds I cannot identify from Big Brook. Please let me know what you think! Any help is appreciated. First up I believe is some kind of pleistocene horse tooth fragment? But I am not sure. Thought it was a ratfish jaw frag at first from the other side, but it's like nothing I've seen. Below, this is what looks to be a fish tooth of some kind, but it seems to have some of the root attached. So no hole visible at the bottom. Slightly larger than a quarter in length!
  9. Hello! I wanted to share some information and the published study of a crab carapace I recently donated to the New Jersey State Museum (NJSM). I found this last year in Monmouth County, New Jersey and thanks to suggestions from fellow forum members, as well as the NJSM, I sent this crab to decapod expert Dr. Rodney Feldmann to study. After review, it was determined that this crab represents a new genus and species and was recently published in the Mizunami Fossil Museum Bulletin. It was an absolute pleasure to work with Dr. Feldmann, who was kind enough to name it after me (Costadromia hajzeri). I also want to thank my good friends at the New Jersey State Museum, and everyone on the forum who helped ID this specimen. This was a really fun project to be involved in! @non-remanié @Trevor @Jeffrey P @Carl @FossilDAWG @Darktooth http://www.city.mizunami.lg.jp/docs/2019031400022/files/02feldmannschweitzer2019.pdf
  10. Hello! I found this last year in a Cretaceous site in Monmouth County, New Jersey last year and wanted to know what it came from. I could be way off on this one but I was thinking possible crocodile due to that 'divot'. It's probably very stream worn and measures a little over a 1/2-inch long. Thanks! -Frank
  11. Possible amber from New Jersey

    Hello! I found this a while back around Big Brook Park in Monmouth County, New Jersey (not a place you would expect to find amber) and was wondering if that is what I have here. Also, I don't see any reason amber couldn't be here but have never found any in this location, so IF it is, could we looking at possible contamination or do you think it originated here. As always, all help is greatly appreciated! -Frank
  12. NJ shark tooth (Pseudocorax sp?)

    I did some fossil hunting with @Krystal in the cretaceous brooks of New Jersey, and we managed to find what we think is a Pseudocorax affinis, but since I've never actually had one in hand, I thought I'd appeal to the experts for confirmation. Thanks!
  13. I found this in Monmouth County, New Jersey (USA) last week and was wondering if anyone knew what it was. When I first picked it up, I thought it was turtle shell but the bone structure doesn't compare well at all with the other turtle shell examples I've found. The top part is what I was focusing on because it doesn't look that was formed as a result of breaks and wear to me. I guess it could be older breaks and if that's the case, I'm pretty sure that I'm out of luck getting an ID on it but I figured I would give it a shot. As always, all help is greatly appreciated! -Frank
  14. Misc bones that need ID!

    A couple more Monmouth finds that need ID's! Quarter for equal size reference throughout all the images. The white bone is very worn down but visibly porous.
  15. New Jersey Cretaceous id help

    Hello! I found this weird fossil yesterday in the Big Brook area of Momouth County New Jersey (Cretaceous). I was thinking possible echinoid but haven't found any like this in the area. Anyone know what it is? As always, thanks in for advance for the help! -Frank
  16. Mosasaur or croc tooth - NJ Cretaceous

    Hello everyone! I hoping to get some clarification to help differentiate Cretaceous crocodile teeth from Mosasaur teeth. These two were found in the New Jersey Cretaceous. The first one is a shade under 1/2 an inch. It is conical and doesn't appear to have any cutting edges (but they could be worn off). I was leaning towards Mosasaur tooth on the second one because of the size of 8/10ths' of an inch, but it is slightly more slender than my other Mosasaur teeth, very conical and the root looked a bit different. It appears to have one very weak cutting edge but I'm not positive. It was pointed out to me that crocodile teeth roots tend to have concentric rings so I was wondering what everyone thought regarding these guys. Thanks! @Plax @josephstrizhak
  17. NJ Cretaceous Unknown

    I found this in my early collecting days (late 90s, early 00s) in one of the typical Monmouth County Cretaceous stream. The texture doesn't at all say bone to me, but that notch has me wondering.
  18. New Jersey Cretaceous bivalve? ID help

    I found this in a Cretaceous stream in Monmouth County New Jersey. I assume it's a bivalve but I couldn't find anything on in the NJ fossil websites. Anyone know what it is? Thanks! -Frank
  19. New Jersey Mosasaur tooth ID help

    Greetings! I recently found this partial (what I believe to be) Mosasaur tooth and the texture of the enamel isn't typical of the Mosasaur I have found. I was wondering if this is consistent with any particular species of Mosasaur or if it's just a different type of preservation than I am used to. It was found in the Monmouth County NJ Cretaceous and the bottom part of the tooth is broken. Thanks in advance for your help! -Frank .6 inch Two cutting edges
  20. New Jersey Cretaceous fossil ID

    Hello everyone! I found this in the Monmouth County NJ brooks. Was wondering if anyone knows what it is; any help would be greatly appreciated. Thanks! -Frank
  21. New Jersey Cretaceous tooth ID

    Greetings! I found what I believe to be a tooth in a Cretaceous tributary of Big Brook in Monmouth County NJ and need help with identifification. It is slightly concave at the root and has a hollow section at the tip and one cutting edge, and has an oval cross section. This spot has yielded a good amount of both terrestrial and marine Cretaceous specimens. It doesn’t seem to match the usual suspects from this area so I would appreciate any help. Thanks! -Frank Additional pictures.
  22. That Ain't Amber, But Maybe A Fossil?

    Hi -- I look my young son to the clay beds in Sayreville, NJ this weekend to look for amber (or, most hopefully, something in amber). We left with just a few pebbles. But in some gravel at the site, he pulled out what he was *convinced* was a shark tooth. While I initially dismissed it as a rock, my son -- who at 7 is pretty up on his game -- made a convincing case for further analysis. There's an enamel-like substance on the "top" side, with a smooth, rounded back, and there appears to be dark fossil remains where the "root" would have been. I haven't tried to clean the clay off of it, (nor am I sure its possible, or even if its clay and not, you know, just a rock). Here are the pics: I don't know where Sayreville, NJ would fit in NJ fossil hunting eras. We usually do the Big Brook/Ramunessen Creek thing here in NJ, and are used to some late Cretaceous finds. And though I know the Sayreville site was a quarry and has a history of some fossils, I was under the impression it was primarily plant, shells and imprints found there. Oh, and rocks. Anyway -- thanks for any help with this!
