Could be some bivalves from late Jurassic or washed out from Cretaceous. Northen New Mexico. All from one place. Thanks.

I found this tooth In desert near Albuquerque New Mexico. Could it be some kind of marine reptile? I would appreciate any ideas about ID. Thanks

I am curious what this could be, I located it in San Juan County, NM, USA. I don’t have a scale in the photos, the item is larger than a golf ball but not much. It has visible bones & skin present. thanks for any help you might be able to give.

Hi experts, this year during one of my trips to the San Diego Canyon in northern New Mexico, I found this mystery fossil. It looked a lot like a mushroom to me, complete with radial fissures on the surface and a hint of a stalk on the backside. It is about 4cm in diameter and about 1cm thick. Any ideas? Coral? Heavily deformed bivalve? Red herring? Thanks for your input!

This isn't the best field shot and I'm not sure how much I can clean up the specimens I brought home as they appear to be glauconite encrusted. My thought when seeing these was Syringopora. They are both somewhat dome shaped. The larger one is about 6" (16cm) in diameter and half of the bottom is exposed and looks like the top. Some of the indents have tiny crinoid segments captured in them.

I found this rock recently in an area where high mesas are eroding near the river. I know there was a lot of Pueblo activity and also likely pre-Pueblo. There is a lot of volcanic rock, but nothing that looks like this. The erosion is exposing tons of river rock of all sizes, that likely came from the north with glacier melt. This area is by the river, roughly halfway between mountains and volcanoes. The rock is smallish, palm-sized, and sort of a squished pyramid shape. It turns blackish when wet, but as it dries it becomes this grayish color. I have looked at it with a magnifier and don't see anything that looks like man made tooling marks, but do notice a lot of features that look like bone. If it is possible to say- it is neither light like pumice nor heavy like a dense rock. I have searched online and the closest thing I can find to it are some images of glyptodont scutes, only my rock is not flat or cookie-like. I am wondering if it could have come from an edge or near the tail of a glyptodont or similar creature. This is causing a lot of head scratching, so please, any ideas or suggestions of places to look or people to contact will be much appreciated. I hope these photos show enough to figure it out.

Staurikosaurus tooth. Measuring 3/8 inch. San Miguel, New Mexico. Triassic .

Dear experts, this is my second aquisition: According to the seller it is a "Staurikosaurus" from the Bull Canyon Fm. in New Mexico (no information on the county provided). The length is 1 cm and the width is about 3 mm. I tried to count the denticles but unfortunately my camera is not made for close-ups. The count might be around 7-8 per mm. In contrast to my last post where there was a wrong formation provided by the seller I was able to verify, that the Bull Canyon Fm. does in fact exist in New Mexico. But that's almost it. According to wikipedia Staurikosaurus is only known from Brazil which makes it unlikely for the tooth to be a Staurikosaurus pricei. On the other hand there is a website on triassic vertebrates of New Mexico which also lists Staurikosaurus pricei in this formation... Here are the compressed pictures of my tooth:

Here are some of my Bull Canyon Formation fossils from New Mexico.

I just made my third trip to northern New Mexico in pursuit of Pennsylvanian fossils. I love this area and I’m especially interested in the Carboniferous periods, and I usually hit a new location on each trip in addition to my favorite location, San Diego canyon near Jemez Springs. But I am always eager to find new locations to hunt! I visited two locations on this trip. I will post my finds from this trip and follow up with another report from previous visits. 1) I spent a few hours at Fossil Hill near Taos. I had little information to work from at this site and had only a little success, but enjoyed the hiking nonetheless. I walked up and down the hill for a few hours, only finding one area with a significant quantity of larger crinoid stems. I also found a single brachiopod and a single Gastropoda. The longest crinoid stem in the image is 1.5” long. This location was near the top of the hill. The fossils were all loose in dirt. I could not find the source layer unfortunately. If you have any good experience at fossil hill, please message me!

Need help identifying. Found in T or C, New Mexico. I think they are bones, but not 100% sure. Found in my backyard and was used as landscaping around a tree. Thanks

Found this weekend in my Dad's back yard in Tucumcari, New Mexico. This is the only piece i could find. Yet to find any info on this thing and never seen anything quite like it before.

I found 2 shell fossils on the top of a mountain in New Mexico sort of near the Chamisa Wilderness area by Guadalupe ghost town. Does anyone know how old it could be and what kind it is?

A mid-Cretaceous tyrannosauroid and the origin of North American end-Cretaceous dinosaur assemblages New species named Suskityrannus hazelae [...]The North American fossil record of dinosaurs from approximately 90 million years ago (Late Cretaceous) is one of the most poorly sampled and least understood times of the Cretaceous Period. The new dinosaur, named Suskityrannus hazelae, is from a dinosaur assemblage that documents this critical interval. Suskityrannus is one of the last smaller tyrannosauroids, which at 9 feet long would have likely weighed less than 100 pounds and stood only about 3 feet at the hip. It is also one of the most complete skeletons of any non-tyrannosaurid from North America – all of the older fossil occurrences consist of teeth, isolated bones, or a partially associated skeleton.[...] News: CLICK Scientific Paper [paywall]: CLICK Always nice to see new discoveries regarding tyrannosaurids

Hi! I recently aqcuired quite a lot of "microfossils" to kick off my Triassic collection, as I personally find it one of the most interesting time periods and while I am aware possibly not all of them are ID'd correctly I just wanted to get some nice fossils from this time period regardless of their ID's. All the fossils I acquired are from the Bull Canyon Formation, Dockum Group, San Miguel County, New Mexico, USA (Norian age) But I myself am not very knowledgeable yet in this material as I just started my collection but I am aware that some if not most of the ID's on these fossils given by the seller might be wrong as everything I read about the Bull Canyon formation says that the formation isn't that well discribed yet. I tried to make the photo's as good as I could, but it wasn't always easy given their extremely small size, so I hope the quality is good enough to work with. So I am kinda hoping is someone here on the forum would like to give it a try to see if he/she could confirm or disprove given ID's. Thank you in advance! The first set of 2 teeth were listed as the Phytosaur "Pseudopalatus" teeth which after doing a bit of research is considered a junior synonym for "Machaeroprosopus" The next collection of 3 teeth were listed as the Pseudosuchian "Revueltosaurus" The next tooth was listed as a "Theropod indet" tooth, and I know there are at least 2 species of theropod present at Bull Canyon, a Coelophysid called Gojirasaurus and a herrerasaurid called Chindesaurus. But I am not even sure whether this tooth is dinosaurian or not. The next set of teeth were listed as "Arganodus" lungfish teeth And the final tooth was listed as a "Sphenodont" (Rhynchocephalia indet.) tooth with affinities to Clevosaurus (which is found in Nova Scotia, Great Britain and China)

Is this an egg? Could use some help with the id

Hi! Amateur hour here! I know nothing, but I love attempting to locate and identify marine fossils, especially in places far away from any body of salt water. I made a trip to New Mexico this past week and found some awesome fossils! Driving east on I-40 from Santa Fe, I stopped in Santa Rosa. Southeast of the city, there is Highway 156, and there are some great pull-offs a couple miles from the Interstate. I attached a picture of the fossil site guide I was using and a couple pictures of the fossils I was hoping to identify. The fossils were on the ground, no digging was done. No water nearby. The closest identifiable large rock seemed to be limestone (I think), but this was found amongst a ton of rock litter of different types. Santa Rosa is a city in and the county seat of Guadalupe County, New Mexico, United States. It lies between Albuquerque and Tucumcari, situated on the Pecos River at the intersection of Interstate 40, U.S. Route 54, and U.S. Route 84. Elevation is 4,616ft. Fossil #1

Hi, Everyone I happened upon this rock while hiking somewhere around the vicinity of San Gregorio Lake near Cuba, NM. Is it more than just an interesting shaped rock? Thanks!

Hi, I believe this is a pelecypod. It was found in an early Pennsylvanian formation sandstone hash plate. Specimen is 3" overall. Would anyone have some thoughts to which superfamily, genus, etc., so I can dig a little deeper on my own? Thank you, Kato

Hello, I wanted to know the ID of this tooth which I was told was Postosuchus. It is from New Mexico Bull canyon and is quite a good sized tooth. Is nicely serrated as well. Regards, indominus rex

Recently completed a lengthy set of walkabouts in the lower Pennsylvanian. I have a lot that I can pseudo-identify and am comfortable leaving them alone for now. OTH, I am hopeful someone with the skills will provide some helpful nudges in assigning more accurate names to the following: I believe this is a coral. This is about 4" tall and 3.5" wide Zoom in I'm calling it a snail but I know that is not correct. Max length is 1.5" And then these mystery spine-like objects on a sort of mash plate. It is hard to tell but the long intermittent one, swooping from lower left to upper right, maybe indeed be a single long strand 3" long

Often on The Fossil Forum you strike up an online friendship based on common interest, then build on it over time through field experiences enjoyed vicariously online, but it is a rare treat to finally cement that friendship in person through a collaborative field problem. After a couple years of threatening to do so, I finally saw a break in the clouds that afforded me the opportunity to burn rubber westward and follow in the footsteps of the Pied Piper of the Puerco, the Chancellor of the Cretaceous, our own PFooley. As a generalist filled with wanderlust, it is hard for me to find a venue these days I haven’t yet sampled, so if you’ll forgive my verboseness and loquaciousness, I think this adventure warrants the long cut of yarn I’m about to spin, complemented by a montage of photos to capture the spirit of our high desert excursion. I had set aside 4 days for this adventure; 2 for driving and 2 for collecting. ‘Twas a long haul from San Antonio to Albuquerque, probably 14 hours with stops, but satellite radio helps knock the edge off the monotony of the yellow line, as did a quick stop at the Lubbock Lake Paleoindian site to stretch my legs. If you are interested in evidence of interaction between the ancients and late Pleistocene beasts, as most of us are, this was a worthwhile side track when in the area. While flat as a tortilla in places, the West Texas experience brings with it its own brand of sensory overload. High winds blew a huge red dust storm and innumerable tumbleweeds in my path, while driving gritty dust into my teeth. The building adventure was palpable. New Mexico terrain along my route also begged to be clipped off at 100 MPH, so in places, I indulged. Then dust storms gave way to sleet squalls just as I got to I-40 near dusk. With higher elevation I began to see lingering snow on the north facing slopes, and feelings of trepidation ensued with regard to what the previous night’s rain and snow had set up for us at the hunting grounds both in terms of road access and perhaps snow covering the exposure. I calmed my nerves by realizing that conditions in Texas weren’t particularly favorable for the same weekend, so I had made a good decision to hedge on New Mexico for the new experience. At long last, on Friday night I arrived at Casa Fooley. And quite a fun bee hive of activity it was. After some handshakes and back slapping with Mike, I met his lovely wife and beautiful daughter. But the fun didn’t stop there. Los Fooley are animal lovers, so I was greeted by quite a procession of curious pets. Rabbits, dogs, a cat, chickens, a tortoise and a turkey all took turns checking out the new guy. All lived in happy community, for the most part. While one Chihuahua quickly took up residence across my legs, another troublemaker puppy started a fight with my new little friend, and they nipped and yapped at each other on the battleground of my lap as the other critters looked on in nonchalance. Shifting alliances rose and fell between animals, a 3 year old ran through the big middle at will, and I found all of this activity to be rather entertaining. But perhaps the most enduring encounter was with the huge pet turkey following me around in the front yard, stomping its feet and strumming its feathers. Finally I turned around and it let me pet its head, which reminded me of a melted red and blue candle. I was a changed man, having pet a turkey for the first time. Having raised it from a chick, Mike showed me that he could pick up and hold his full grown, feathered friend. To boot, it roosted on a fence by the window where I slept that night, literally 3 feet away from the bed I slept in, silhouetted and standing sentinel.

Date of Trip: June 2018 Location: Quay Co., NM, USA Age: Late Triassic Formation: Redonda This was the second of a number of hunting trips across the country this summer (the first was Silex, MO, reported earlier). This will be the Triassic Vertebrate report from this trip. Triassic invertebrate report will have to wait (perhaps exciting news ). Triassic plants and Cretaceous inverts from the same general locality will also be reported later. These are finds from a coarse-grained fluvial deposit rich in fish remains. In one layer, ganoid fish scales were almost as abundant as the mineral clasts. Here is a view looking down on the bedding plane showing the fish scales laying on top: Here is the same chunk of matrix cut across the bedding planes (i.e. in side view) showing numerous scales in transverse section: Disaggregation of the matrix and rinsing through a sieve yields numerous small, complete scales (scale in mm): Large scales are present in the matrix but heavily fractured and very difficult to extract intact.

With a little bit of the fern revealed I took my smallest chisel and smallest hammer to split this specimen. Width of left specimen is 5" (approx 100mm) about 25mm of fern was showing initially

Hello! I’m hoping to identify this fossil I found while wandering a mesa just south of Santa Fe, New Mexico. It was laying neatly in the sand just waiting to be found. The pits on the end look very much like bone marrow. I chose to leave it at the ranch where I found it, so I only have one pic. I could get more if needed! Thanks!
