  1. Fun morning hunt at NSR. Pretty good sized shark tooth for NSR.
  2. I saw the first opportunity to get back to the North Sulphur River yesterday when the temps were going to be below normal for a change. There was a really nice breeze blowing down the river. Went to a spot on the river that I have only been to once before and access is pretty poor. Thanks to whomever added the rope, it helped, especially getting out! Quantity of the finds were low but the quality of what I found was great. Found the largest Tylosaurus tooth I have ever found with a diameter just under an inch. Also a shark tooth and one nice mosasaur vertebrae. I always enjoy the chance to find an artifact, ever though they are rare, or at least for me they are? I liked the way that JarrodB displayed his artifact recently, so I photographed this one the same and it turned out pretty good. Not sure the type, could be a Marshall, usually I find Gary's, so this was a nice departure. I will be watching for another cooler than normal Texas summer day to get back to this spot.
  3. I only had a couple of hours so I stayed right below the creek bridge. I had a couple of cool finds.

  5. Our trip to GMR

    So we finally made it out to GMR to do some hunting. We left Greensboro about 7 am and arrived around 9:15. We walked around for a little bit to scout some areas, and finally found a good starting point. It was slow at first, but we started making really good progress when I found a 2" goblin shark tooth. We continued on throughout most of the day finding tooth, after tooth, after tooth... We found several Meg fragments, some super nice great whites, mako's, 3 mosasaur teeth (the smaller round one might possibly be a crocodile but were not 100% sure), and quite a few belimnites. After we finished for the day we stopped by @powelli1's house so he could check out some of our finds. He's a great guy and has an absolutely amazing fossil collection. When I say he has 15,000 fossils in one room, I'm not exaggerating whatsoever... He helped confirm the ID's of some of our finds, and was kind enough to give us a tour of his collection in the process. After heading home we decided to photograph some of the nicer finds and count everything we brought back. All together we had 944 shark teeth, 3 mosasaur (except if that smaller round one is not a mosasaur tooth), 1 unidentified fish tooth, and 59 belimnites. Here's some photos of everything we found today.
  6. Mosasaur tooth

    This is a recent acquisition from everyone’s favorite auction site. It’s 6.8 cm and was reportedly collected from Ouled Abdoun. I was curious what you all thought. For what it’s worth, it was listed as hainosaurus. Thanks!
  7. 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
  8. As suggested by some members of this forum some time ago... I have begun a small excavation project to rescue the mosasaur teeth trapped in a fabricated jaw bone and fossil which I purchased as a child. Ever since those days I have dreamed of going out into the Karoo and digging up remains of prehistoric animals, but sadly, I was not adept in the sciences and the arts took over my career choice. So, instead of getting a children's excavation kit, why not try and rescue real fossil teeth? So with a dental pick, brush and magnifying glass I have begun working into the fabricated layers. I started outside of the direct fossil radius, and have scraped away to reveal the root of the tooth first. My plan is to keep excavating downward so as to remove the tooth from the fabrication for finer work to reveal the tooth. Any tips on the excavating process? How can I distinguish the point between fabrication and fossil tooth at this early stage?
  9. I haven't had much time to hunt lately but I did manage to squeeze in a North Sulphur River creek hunt. My finds were not great but I did manage to find a nice variety. The fossil horse cannon bone is probably my favorite due to the preservation. It's solid rock. Lol my grandson carried it around the house all night when I brought it home. The Xiphactinus vert, old bottles and artifacts were a nice bonus to the usual Mosasaur material. This creek has some killer flint in it so I can see a nice arrowhead coming soon.
  10. Godfrey, S.J., Weems, R.E., & Palmer, B. 2018 Turtle Shell Impression in a Coprolite from South Carolina, USA. Ichnos, (ahead-of-print publication) 8 pp. ABSTRACT Coprolites (fossilized feces) can preserve a wide range of biogenic components. A mold of a hatchling turtle partial shell (carapace) referable to Taphrosphys sulcatus is here identified within a coprolite from Clapp Creek in Kingstree, Williamsburg County, South Carolina, USA. The specimen is the first-known coprolite to preserve a vertebrate body impression. The small size of the turtle shell coupled with the fact that it shows signs of breakage indicates that the turtle was ingested and that the impression was made while the feces were still within the body of the predator. The detailed impression could only have survived the act of defecation if the section of bony carapace was voided concurrently and remained bonded with the feces until the latter lithified. Exceptionally, the surface texture of the scutes is preserved, including its finely pitted embryonic texture and a narrow perimeter of hatchling scute texture. The very small size of the shell represented by the impression makes it a suitable size for swallowing by any one of several large predators known from this locality. The coprolite was collected from a lag deposit containing a temporally mixed vertebrate assemblage (Cretaceous, Paleocene and Plio-Pleistocene). The genus Taphrosphys is known from both sides of the Cretaceous–Paleogene (K–Pg) boundary so, based on the size of the coprolite and the locally-known predators, the juvenile turtle could have been ingested by a mosasaur, a crocodylian, or a theropod dinosaur. Unlike mosasaurs and theropod dinosaurs, crocodylian stomachs have extremely high acid content that almost always dissolves bone. Therefore, the likely predator of this turtle was a mosasaur or a (non-avian or avian) theropod dinosaur. selected quotes: Until now, no coprolite was known to preserve a vertebrate body impression. Here a single coprolite (Calvert Marine Museum Vertebrate collection, CMM-V-4524, Fig. 1) from Clapp Creek in Kingstree, Williamsburg County, South Carolina, USA is documented to preserve a natural mold of a partial turtle shell (carapace and scutes) referable to Taphrosphys sulcatus (Bothremydidae, Testudines). This occurrence provides another example of how coprolites can preserve evidence of trophic interactions that cannot be known solely from the study of body fossils. Among the twelve turtle taxa known from the Paleocene in South Carolina (Hutchison and Weems, 1998), and the nine or ten taxa known from the Late Cretaceous (Weems, 2015), only Taphrosphys has all of these characteristics (Fig. 5). While Adocus is similar in that it also has an elongate first neural and first costals, it differs in that it had a square-shaped second neural (Meylan and Gaffney, 1989) quite unlike the hexagonal second neural seen in the CMM-V-4524 carapace impression. Based on this identification, the stratigraphic origin of this specimen can be restricted either to the Late Cretaceous or early Paleocene (Danian), because Taphrosphys has never been reported from the Williamsburg Formation (Thanetian, upper Paleocene). It is notable that “Taphrosphys leslianus,” now considered a junior synonym of T. sulcatus, has relatively wider vertebral scutes than are found in adult specimens. This suggests that, as T. sulcatus grew, its vertebral scutes became relatively narrower and its pleural scutes relatively wider. Carrying this trend back to hatchling size implies that hatchlings of T. sulcatus probably had very wide vertebral scutes as seen in CMM-V-4524 (Fig. 5). Identification of this specimen as T. sulcatus greatly expands our knowledge of the growth and developmental stages of this turtle from hatching to maturity. Based on the paleoenvironments in which specimens of T. sulcatus are found, this turtle probably was an inhabitant of both estuaries and shallow marine environments. Based on the hatchling or near-hatchling size of the specimen described here, it was probably living in an estuarine environment at the time it was eaten. In addition to a mosasaur, the predator may have been a theropod dinosaur (including avian theropods). The tyrannosauroids Appalachiosaurus montgomeriensis (Carr, Williamson and Schwimmer, 2005) and Dryptosaurus aquilunguis (Carpenter et al., 1997) are among the known Late Cretaceous theropod dinosaurs from eastern North America that would have been large enough to produce coprolites of this size (Weishampel, 1990), so one of these animals could have been the predator if the coprolite is of Late Cretaceous age. If the coprolite is of Paleocene age, however, then it most likely was produced by a large bird. Although poorly known, there were a number of species of Late Cretaceous and Paleocene birds large enough to produce coprolites of this size, including a Paleocene pelagornithid (relevant literature summarized in Mayr, 2007). Bird predation is a major factor limiting turtle hatchling survival today (e.g., Janzen, Tucker and Paukstis, 2000), so it is likely that a similar pattern existed in the Late Cretaceous and early Paleocene. The small (i.e., young post-hatchling) size of the turtle shell and the fact that the shell shows signs of breakage both indicate that the turtle was ingested and that the shell impression was made while the feces were still within the body of the predator. The way in which the feces tapers immediately beyond the turtle shell impression (Fig. 1B) suggests that as the shell was voided, the cloacal aperture was stretched more than it might ordinarily have been. CMM-V-4524 is the first-known coprolite to preserve a largely complete body impression; though turtle vertebrae have been reported from Late Cretaceous shark coprolites (Anagnostakis, 2013, fig. 9J; Schwimmer, Weems and Sanders, 2015). This specimen also represents the first-known record of embryonic and early post-hatchling turtle scute texture preserved in the fossil record.
  11. After coming back from college this Saturday I knew exactly what I had to do: hit the streams in NJ to find some fossils. I lived in Ohio for the majority of the year and did not have access to a car or fossils. I had to take advantage of the resources that I regained after coming back home. I have had a myriad of dreams about fossils from NJ and had to finally get in the brooks to live out those dreams. Frank seems to have taken advantage of the rain in the last month (he just posted another subject in Fossil Hunting Trips) - I missed this opportunity and begged my parents to go surface hunting for me to no avail. I went with my grandma on Tuesday 22 May, and again with my two friends on 23 May. I stayed in the streams for about two hours on Tuesday and found a partial mosasaur tooth. Then on Wednesday I found a worn mosasaur vert and some enchodus jaws. I hunted for 3.5 hours on Wednesday. I mostly sifted but also used a rake and a clear plastic bin to search for things in the water; this is how I found the majority of the enchodus material. Here are the finds.

  12. Hello! It has been extremely rainy here in New Jersey the past few months month but I have found a few windows to check out the New Jersey Cretaceous streams in Monmouth County. As you would expect, the water levels have been high but at least the water temperature has finally warmed up! I figured I would share a few of my favorite finds over the past few months. They are, in order - an enchodus jaw section with teeth, a spondylus inside a Pycnodonte, two Mosasaur teeth (I really like the smokey blue colors on the smaller one), an echinoid, ammonite and baculite pieces, and ischyrhiza rostals, Cretaceous turtle shell, a gastropod, mosasaur tooth, bivalve, and enchodus fangs in the last picture.
  13. Preparation advise

    Looking for advise on a mosasaur jaw in sandstone. I’m wondering if I should do more prep to show more of the jaw still hidden in sandstone, the only problem is the jaw bone is fragmented. Any advise would help

  18. NSR Mix

  19. I went on a 6 1/2 mile kayak adventure with a couple of friends on the North Sulphur River. We started off the day at 7AM by seeing 2 bald eagles and almost getting one truck stuck in the mud. We managed to get the truck out and started our adventure. As soon as I got down by the bridge I found one of my best artifacts to date and a nice piece of mastodon tooth enamel. We got a mile or so in and something made me ask my friend if he had the keys to his truck that was parked 6 1/2 miles downstream? Lol he had left them in the other truck without thinking. He went back and got his keys and the adventure begin. We saw very little footprints the entire trip. We didn't find many artifacts but I filled up a 1 gallon ziplock with mosasaur bones and other random fossils. One of my friends found his first shark vert, mosasaur vert and point so he was really excited. I gave my new hunter friend all my lower quality items and didn't bother taking pics of them. The water was low in some places so we had to drag the kayaks a lot but it was fun. We were finding so much stuff that we realized we would never make it the other vehicle before night if we did not quit hunting and paddle. It was so hard passing by untouched bars lol. We managed to make it back to the bridge by 7PM which was 12 hours later. Getting the kayaks up the steep bridge at the second location took all 3 men and a long rope. I got home at 9:30 PM. I'm sore but found some great fossils and artifacts. My phone died early in the trip so I missed out on some great pics. For some reason I can only post a few pics at a time since the latest update.
  20. Mosasaur ID

    I'm really pleased to have acquired this lovely Moroccan mosasaur jaw this evening. I am flat broke, so I had to persuade/bully my family to all chip in as an early birthday present, but it's a lovely example, with a number of original in-situ teeth. I was wondering whether there might be enough there to narrow down the species? I included a British pound coin for scale, which I appreciate is not very useful for an international audience. It's 20x17 inches. The jaw, not the coin.
  21. I explored a new creek spot on the North Sulphur River and had a good day with a nice variety. The Native American pottery and artifacts were a nice surprise at NSR. I rode over to Post Oak Creek only to find my favorite spot posted so I explored a new spot for one hour and found a few nice teeth.
  22. Went for a trip to the North Sulfur River Wednesday and had a great time. Found some cool fossils and some great points. The Mosasaur jaw section was a nice find but i was even more excited when i flipped it over. I found a couple of emerging replacement teeth pushing into their spot!
