  1. I live in north central NM on the continental divide. Is it possible that there is an actual bone covered with sand sticking out of this sandstone?

  3. The Rio Puerco Valley was my introduction to fossils...it immediately caught my attention...lit a match...became a place I am always eager to revisit...search...learn about... ...and in roaming it, have learned about myself. Many of my adventures in the Puerco are posted here, here...here and here...and here. From here on out, my excursions will be shared here. May you find happiness in your hunting. -P.
  4. A couple of years ago, while on a romp through the Rio Puerco Valley, I found this ammonite. Since then, I have attempted to find a proper i.d. for this specimen through literature and documentation of New Mexico's Late Cretaceous ammonites. With very little luck, the closest resemblance were ammonites in the subfamily Puzosiinae, which are not documented from New Mexico. Today I decided to show the curator and the ammonite researcher at the New Mexico Museum of Natural History and Science. Good news...they did not know what it was! ...pretty exciting. Anyhoo, I have donated it to be studied but figured I would post it here as well. Unknown ammonite from the Late Cretaceous (Cenomanian) Paguate Mbr. of the Dakota Formation - New Mexico, USA. I doubt they'll be jumping on this right after lunch, but I will let ya'll know the results as I do. Happy hunting, -P.

  6. Hi there, Here are 4 Aetosaur vertebrae I have from the Bull Canyon Formation, Quay County, NM. Just wondering if they are indeed Aetosaur verts? If so, can a genus be pinpointed. It has been restored and repaired; the seller found it in several pieces. Thank you! Jojo Second vertebra
  7. It's been a good week for fossiling in New Mexico...found this one in a dry wash in west-central NM. The nearest upstream units were (from nearest to far) kmf-Menefee, kpl-Point Lookout Sandstone and the Satan tongue of the Mancos shale (kms). I've always thought of the Western Interior Seaway as fairly shallow and the shark a deep variety, but the lit says the extant cousin patrols 100m to 1,300m and the WIS was as deep as 750, so there's habitat, I would think. Thoughts? Thanks!
  8. Hello, Does somebody here knows where I can obtain permian or triassic vertebra fossils (no fish, exept shark) and reptiles, amphibians.... I prefer good quality. Thanks Thijs
  9. Found this specimen at approximately 9,500 feet in elevation in the Albuquerque, NM area. I have taken photographs with measurements. Was found in loose to rocky soil on the surface. I did no digging to locate specimen but basically picked it up off the ground after noticing it sticking up. I have no knowledge of what it could be other than the fact that it looks like a tooth. Thanks in advance.
  10. This by far has been the most ambitious trip that I've done, but it was certainly worth the long drive times, poor truck stops (to sleep at), and lack of time to sleep and even eat. In just 10 days I traveled through 7 states (WY, ID, MT, CO, UT, AZ, NM) and covered at least 4700 miles (I might actually have broken 5000). Not only did I alot some time for general fossiling/rockhounding, but also time to stop at a few of the more "touristy" types of places (national parks/monuments, etc). The first day I visited a couple sites in southeastern Montana, with the first being known to produce oysters. It took longer than expected to find, but afterwards I discovered the site to be completely loaded with oysters and oyster fragments. The majority were completely covered with just a tiny bit showing, but after finding a few it seemed like all of them kept popping up one after another. Most were under 1cm in total length, but I found a couple that were larger. The next site was a little disappointing in that due to poor road conditions, I couldn't make it out to a few of the stops that were rumored to yield crinoid pieces (given that I've been working on crinoids for the past year at university, this was going to be one of the highlights of my trip for rockhounding). But I did manage to find one of the stops, which while it appears mostly picked over, did produce one nice piece of coral and several pieces with fragmented clams. This was actually a place that encompassed much more land than I anticipated, so I hope to return next year and alot several days there.
  11. Hello. I went on a long hike a few days ago and stumbled upon this in a large Cambrian rock. I believe most of the outcrops in this area are very early Cambrian as I find a lot of Archaeocyathids. Is this structure somehow related to the Archaeocyathids? It's about 6 inches in diameter. I have an average sized hand. Another fossil I'm trying to figure out is this.... Sorry the pic is a bit dark. I'm thinking maybe it's a priapulid with the bottom section broken off? The probiscus appears retracted on the upper right hand side, and the segmentation of the organism is clear. Thanks. Hat.

  13. Hi everyone! A colleague of mine is headed to Albuquerque sometime near the end of June for IB training (she's a teacher like me), and she has decided to stay on for the weekend after her training session is over in order to do a little hiking with her husband (who will be heading down to meet her for the weekend). She loves rocks and fossils, so she was hoping to do a little collecting while she's there. Are there any easily-accessible sites that she would be able to collect from? Thanks! Monica
  14. I'm guessing agatized coral not 100% sure though since I'm finding here in Los Lunas, I'd like to get a second opinion or corrected if I'm wrong, what do you guys think?
  15. so I've been wanting to take the family out to the Rio puerco site but have no clue as to what part of the valley to go look, can anyone point me in the right direction for the BLM site? TIA!
  16. Dear Forum members, I own a few microteeth which are said to be from the Bull Canyon Formation of San Miguel County, New Mexico. I have tried to find a scientific paper on the Bull Canyon Formation locations of San Miguel county, but I can only find Garita Creek Formation locations. Does anyone know where in San Miguel County all those micro teeth come from? Is it really Bull Canyon Formation or another formation? Thank you for your answer, Sander
  17. so in the deserts of new mexico these were found. not anything I have ever seen here and was really curious what they are. they are agate based but shaped like vertebrate so I'm lost. any help would be greatly appreciated
  18. I have two Triassic coprolites from the Bull Canyon Formation, Quay County, NM. The first one has an impression/imprint that I have not been able to identify. The second has a protrusion sticking out of it. I had hoped that by prepping out the the protrusion, I would get lucky and it would match up with the marks on the other. Unfortunately, I now have two things that I can't identify. @Carl 1. Is there anyone out there that wants to take a stab at identifying the imprint in this one? It does appear that there are some remnants (white) of whatever it was that made the marks.
  19. The location where this was found contains both aquatic and terrestrial animals from floodplain habitat. In this coprolite, a small tooth plate impression with residual fragments can be seen on the surface. Since a similar tooth plate was not found within the coprolite itself, it is unclear whether this is an undigested prey remnant or if it was embedded upon deposition. An unidentified bone and numerous fish scale inclusions were revealed using X-ray computed tomography. This specimen was scanned in April 2016 by the University of Minnesota X-ray Computed Tomography Lab using a X5000 high resolution microCT system with a twin head 225 kV x-ray source and a Dexela area detector (3073 x 3889 pixels).
  20. I have seen this type of trace many times before...each time I wonder. Do you have any ideas? The knife is 3" in length...thank you for your thoughts.
  21. Hey all, Had the honor of being taken fossil hunting with Pfooley recently. Found my first ammonites! I'd been wanting to find some for a long time. Was a great experience and I look forward to more trips soon. Checked out the famous "Windmill Site" first. The drive there was amazing in early morning. I busted open my first nodules... Poor quality picture of the Windmill Site finds. Nice variety in there. Far left is a large bivalve and there's a large gastropod on the far right. We moved on to find some other ammonites. My best find of the day was this large whole Spathites. Had a blast and can't stop thinking about the next time I'll find myself out there... Thanks again Mike!
  22. Hey everyone, I'm writing this out here because I'm trying to find a buddy or a partner to go hunting with. I've been in New Mexico for just over a year now and there are some hunting grounds I'd like to explore that would probably be quite a bit safer (and more fun) with a partner. I've been lurking on these forums since I moved out here from Fl. I'm a 24 year old grad student at UNM studying engineering so I don't have any formal geology education but I like to read and learn about it! Not really experienced at hunting, just a guy that enjoys being in the outdoors and wants to learn more. Currently looking into Galisteo Dam as another user on the site has shown. Reading the paper in the attachments and checking out geologic maps. If anyone is interested let me know. - Ken Ammonoid Biostratigraphy of the Upper Cretaceous Carlile Shale at Galisteo Dam, Santa Fe County, New Mexico.pdf
  23. Found what is believed to be a tooth fragment in the mountains NW of Ruidoso, NM. I'm hoping someone can help identify it.
  24. I found this the other day and the distinct shape immediately caught my eye. It was found in the Raton basin at about 7500 feet. I found it on a hillside about 50 feet up from the river. There were many broken leaf fossils around and other interesting patterns that I believe were plant based (wood, roots, etc.) The rock is 4.75" x 3.25". The anomaly is 2.25" from edge of rock to the tip and about 1.5" at it's widest point.
