  1. Hello all! I have finally finished sorting close to 300 pounds of anthill from north central New Mexico. I recovered (literally) close to 18,000 fossils! Most are identifiable, but there are a few that I can't put a name to. I am going to put up several for your expert analysis (not being facetious, you guys have an enormous amount of knowledge!) to see what you have to say. I will repeat this introduction for each grouping of photos, only changing the take number. Thank you all in advance! This fossil shows the internal structure that I normally see in Ptychodus. But when I flip it over, it is totally smooth. Any ideas?

    BONE FRAGMENT REVISITED

    I am posting new photos of the original item in question in addition to photos of some of the other finds. I sincerely appreciate everyone's comments and interest in this subject and above all I thank you for your time and patience. I will not cover anything from the original thread simply for lack of time so I suggest you reference "bone fragment" if needed. So the following photos are of just a few of what has turned out to be something wonderful in my opinion. The items that I and a trusted friend have uncovered are either not much at all or something very awesome. Again this is only a small fraction of things still being found on the surface to no more than 3 inches below the surface.

    Mystery..

    This is one out of the mystery box I purchased so no clue as to its orgins. It is also very heavy therfore dense.
  4. Sinestia

    A little help?

    As mentioned in my opal post this was also in the mystery box and was looking for any ideas. About the size of a deck of cards.
  5. Sinestia

    Possible tooth?

    Found this roadside while taking dogs for a walk. Its a long dirt road going north to south and ends at Hidden Valley Ranch, Luna County New Mexico. It is likely nothing but I found it worthy of asking.

    Scorpion?

    Was really thinking freeway travel center souvenirs when I found this one any help would be great.. I did enhance the images just a bit as in contrast and brightness to better show it.
  7. Troodon

    Deinosuchus from New Mexico

    The attached paper describe six osteoderms, two vertebrae, and a partial tooth discovered in the Menefee Formation of New Mexico and representing one of the earliest occurrences of Deinosuchus on the Laramidian subcontinent. https://peerj.com/articles/11302/

    Guadalupe Mountains National Park

    I found this a few years back near (but not in) Guadalupe Mts National Park. Is it a sponge, coral, algae, or something else? Piece is about 6 inches across. Thank you for your help.
  9. Sinestia

    Tooth or claw?

    I was super excited when I found this piece earlier this week while mending fences and would appreciate any help..
  10. Sinestia

    Possible vertebra?

    I have a little over 60 acres here in Southern New Mexico so I find some great specimens almost daily, unfortunately my knowledge in this field is minimal at best so I am grateful to read your comments and very eager to learn.
  11. It was hard to believe that six years had passed since I last visited the badlands of the San Juan Basin...if you are interested, I posted a few of those previous trips here and here. With a new field season upon us, @Opuntia and I made our first (of hopefully many) exploratory mission to the Upper Cretaceous Kirtland/Fruitland badlands of the SJB... ...so interesting and beautiful. I am looking forward to getting back up there to see what may lie around that next bend. Until then, Happy hunting. -P.

    Fossil or artifact?

    Very new to the forum so my apologies if I am incorrectly posting or otherwise. I am an avid meteorite hunter and have been for over 30 years so I do run into many fossils and artifacts so with that said I have many to show and many questions to ask . I'll start with this one and would appreciate your input on what this might be.

    Godzilla Shark

    Full skeleton of a 300 million year old shark found in New Mexico nicknamed the Godzilla Shark has been officially named dracopristis. https://news.yahoo.com/news/godzilla-shark-discovered-mexico-gets-204437107.html
  14. Is anyone familiar with the Paleozoic formations on Bear Mountain, just northwest of Silver City, New Mexico? I have collected there a couple of times but am unsure as to which formation I was sampling. My first guess is that it is the Andrecito Member of the Lake Valley Limestone (Mississippian (Early Osage) but I know that there are also fossils found in the underlying Devonian Percha Shale, especially east of Silver City. There are a variety of brachiopods, bryozoans, rugose corals, and some crinoid bits. The photos show one of the larger brachiopods. Do you recognize it? Thanks.
  15. Friday was a second trip out the the Windmill sites with a quad and a geologic map overlay. I scouted out a site further north that was across the arroyo. I am a geologist by training but not so much about fossils or minerals, mostly tracking layers and mapping.

    Todiltia schoewei (Dunkle, 1942)

    Alternative combination: Leptolepis schoewei. Taxonomy taken from NMNH Catalog Number USNM V 17903. DIAGNOSIS after Schaeffer & Patterson (1984): "Middle Jurassic teleostean fishes of leptolepid grade, but differing from similar fishes in having only chordacentra until late in growth. The chordacentra receive perichordal additions only in the midcaudal region, and only in the largest specimens. About 50 vertebrae, 30 abdominal. Dorsal fin in the middle of the back with about 16 rays; anal originates beneath posterior edge of dorsal, with about 14 rays; pelvics beneath dorsal origin, with about 12 rays. No bone-enclosed rostral commissure or rostral pitline; supraorbital sensory canal not meeting infraorbital, and with three medial and two lateral branches above the rear of the orbit…." Identified by oilshale according to Schaeffer and Patterson, 1984 on the basis of the leptolepid maxilla and praemaxilla, fins and fin position, weak scaling, and absent or weak chordacentra. Line drawings from Schaeffer and Paterson 1984: Reference: Dunkle, D. H. (1942): A new fossil fish of the family Leptolepidae. Cleveland Mus. Nat. Hist., Sci. Publ., vol. 8, pp. 61-64.

  17. This carnivore coprolite was found in the Bull Canyon Formation (Upper Triassic - Norian), Quay County, New Mexico. It contains numerous fine, boney inclusions (white). There also appears to be a small jaw inclusion that has a shape similar to amphibians. Originally, I couldn't figure out why there would be so many finely crushed bones. It is not something I usually see. When bone fragments are present, they are usually larger. That said, fibrous osteoderms are also found in the same area. I have included an image of a fairly large one. They are made up of fine, boney fibers that have a configuration similar to woven fiberglass. So here is what I am wondering: 1. Could the fine bone fragments be the indigested remains of these boney osteoderms? Perhaps from juveniles? I do have some small fragments (somewhere), so I could dissolve them to see how they fall apart. 2. Does anyone know what type of animal had these fibrous plates? All I could find is information on osteoderms from phytosaurs and aetosaurs. Neither of those appear to be fibrous. I have found osteoderm fragments of that type in coprolites, but they look nothing like this. I know some of the Triassic amphibian-like tetrapods had osteoderms, but I haven't been able to find information on these. Since the shape of the jaw in the coprolite has a similar shape to those animals, I'm thinking they may have had this type of osteoderm. Of course more than one type of prey may have been on the menu. Osteoderm Magnified Osteoderm I've been away from the forum for a while, so I'm hoping there are new folks out there that specialize in Triassic critters. As always, thanks for looking! @Carl @MarcoSr

    Substrate?

    There are fossils in the background gray sedimentary, but so much better preserved in brown! Why? Almost like this pile of creatures is on display, a 7 inch blob just laying on top of gray stone. I'm more interested in how these were preserved than what they are.
  19. I collected these presumed plant parts at a late Pleistocene site in Roosevelt Co., NM. They are mineralized, and came out of the same layer of sediment as Mammoth, Equus, Ground Sloth, etc. The triangular "stem" parts remind me of Sedge, but I'm not sure.
  20. It's been a long time since I've written a trip report. Not that I wasn't hiking, I was hiking like mad and finding stuff. Just didn't get around to documenting in the latter part of 2020. Too much craziness. A couple of days ago, I went in search of an extremely elusive shale formation, that contains some of the loveliest ferns I have seen. My records show I specifically planned 13 hikes last year trying to find another exposure. That was over 100 miles of fruitless searching. Zero. Zilch. Well, two days ago I found another small exposure. Scenic photos of the journey follow starting with walking uphill on an Ordovician rock bed The Ordovician transitioned into this Silurian bed with Devonian formations rising above it on the left Although fairly stumble-free walking this was relatively steep. That day I ascended 2,800 ft with my big pack full of tools, food and drinks. A nice shattered chert nodule in the Devonian. Just to show not everything has fierce thorns here, some 'Cushion Buckwheat'
  21. Subject is a bit off topic, but while out exploring a local canyon for Ordovician fossils, I chanced upon this strange exfoliating section in a formation known as the Valmont. Would anyone happen to have knowledge on the processes behind this? The area was not conducive for finding fossils. This is 'as viewed' from the side. It is not taken from above. The bed is in a normal horizontal orientation but exposed in a staircase cleft. Sedimentary rock formation Found in the orange box in this photo
  22. Hello everyone, I am pretty new to the fossil hunting game, mostly just picking up a few shells or leaf imprints when I am out hiking but when I returned to school in Florida I started to get a bit more interested in actually researching and exploring with the intention of fossil hunting. On the drive back to Florida from Denver I decided to break the trip up into 6-8 hour drive days and camp while hitting some fossil opportunities. Also it kept me fairly isolated with Covid restrictions. With that in mind I planned a route to hit a few different sites: Quay County, NM has reports of phytosaur teeth although I was mostly hiking at this locale. Lots of literature on the area with some nebulous directions, I puddled around on a small streambed I scouted out prior to the trip and ended up finding a fossilized vertebra which I will call a phytosaur based on its size and reports that the area appears to host these species almost exclusively. I was a little out of my element and spent a bit more time hiking and enjoying the West side of the US while camping at the free Mills Canyon Rim Campground which I enjoyed very much. Mineral Wells and Jacksboro Fossil sites, TX - well known sites that I spent a bit of time at. Pretty much every other fossil I found on this trip came from these areas. I made a mistake and passed up my planned campground at Kiowa instead staying at Possum Kingdom campground because the reviews were good and was sorely disappointed. The area is very built up and it is more of a place to bring a boat and an RV than what I wanted. But never know unless you try, there is a nicer campground at Fort Richardson near the Jacksboro locality I would recommend instead. Found a few different specimens including an intact crinoid cup, a small trilobite, and some other common specimens. Embarrassingly while at mineral wells I found what I initially took to be a trilobite in Matrix and was incredibly excited as it was by far the most distinguished find there. Fast forward to being home I cleaned the specimen and started trying to id it only to find that it didn't really fit any description...then I gave it a quick lick and discovered that it was very much still organic and warm so I have included a picture if someone wants to tell me what strange bug eggs or cocoon I likely licked. 100% not a fossil though as it started to ooze once squeezed. North Sulfur River, TX - Flooded and rained out so passed it up largely because I didn't want to try camping after wading in freezing water all day. Campground is listed under freecampgrounds and is on the Ladonia Wildlife Area. I'll hit this site on the way back. Mississippi 'Red Hot Truck Stop' Locality, MS - No luck here either although I didn't put in much effort, the campground I selected was closed so I spent a night in the back of my car and felt like getting back to Pensacola. In retrospect, I should have spent more time touring around this area but the Red Hot Truck Stop is now a Walmart parking lot and I didn't really feel like poking around that area after spending the past week hiking around some of the areas out West. So overall, a mixed success trip but, like I said I was more looking for a good way to split up a drive back home and my experience is pretty limited. I've included pictures of the specimens I found with labels, if anyone from the areas wants to correct them please feel free, I am sure that many of them are wrong. If you would like a better picture of a specimen just let me know. A: Phytosaur Vertebra B: Assorted Crinoid Discs C: Chonetinella sp. - Brachiopoda D: Ditomopyge sp. - Arthropoda E. Bactrites sp. - Mollusca...some sort of orthoconic nautiloid
  23. Every now and then I find something odd on the ground in the backcountry. Do not feel this is a fossil. At first glance I thought this was just some siliceous ooze with intricate folds. At second glance I noted the broken surfaces were not conchoidal as one would expect with silicate materials. It almost appears like extremely fine-grained basalt on the broken ends Specimen is 1.5" (38mm) long and 1.25" (32mm) wide. Thickness is 3/8" (8-9mm) I'll call this the top view. Primarily very dark black Bottom view has a decided reddish cast in places. Note the broken end on the left. Another broken section on the side. Small vesicles. Some strange inclusion on the left. Another exposed side section If it is igneous in origin that would be interesting because the closest igneous activity is about 70 miles away and would imply transported in by ancient peoples. Any geologic thoughts to send my way? Thank you, Kato
