I recently found an echinoid in the Prionocyclyus hyatti ammonite zone of the Upper Cretaceous (Middle Turonian) Semilla Sandstone Member of the Carlile Shale. These creatures are not common and until now... ...I have only found fragments. After a quick clean and some photos, I wonder if there is enough diagnostic material left on this crushed and eroded specimen. scale= 1/4" I do not know much about echinoderms, but I am very much interested in learning more. Is there enough of this creature to label a genus? Thank you for your help.

As the temperatures are heating up in the desert I'll be moving more into the high country collecting. This will bring me to formations bearing ammonoids. My understanding is I'll be finding versions of goniatitic ammonoids as opposed to true ammonites that didn't emerge until the Jurassic? I'll be primarily hunting in upper Pennsylvanian or lower Permian formations. These will be new formations to me and difficult to determine the age. There are no stratigraphic maps for the areas I'll be searching to guide me. Hopefully I'll find additional marker beds or fossils that will help date the formations and make them easier to find by association. It appears that obtaining complete specimens will be rare as the best preservations seem to be in dense limestone. Here are a few remnants. Is it possible to discern the species from these limited portions? Also, is there a good link to understanding and being able to recognize ammonoids from the Pennsylvanian to Permian? From what little I can read from research papers for our geology they have not been studied well and there is little reference to them. The specimens range from the smallest being 150mm to largest being 200 mm (6" - 8") in diameter. I feel the preservation is generally nice but finding complete specimens will be pure luck. Thank you for any beginners tips and guidance. Kato

Sacramento Mountains - New Mexico, Ordovician - Mississippian exploration
Kato posted a topic in Fossil Hunting Trips
This was purely an exploratory hike to a remote area with no expectation of finding much. In that regard, I was not disappointed. I'd previously last covered some of this ground about 5 years ago and had forgotten how formidable it was to get into. The walk in a rocky canyon bottom for about 2.8 miles before taking another rocky side canyon ending at an Ordovician-Silurian dry water fall. Approaching the base of the dry water fall with Ordovician bedrock that was pretty much non-fossiliferous. At the base of the dry water fall to get a nature shot. This looks like it should be climbable and, perhaps it is, but I'm getting a bit too long in the years for such risky business. I took a bushwhack side trip up a steep hill. Fortunately, it had rained recently and the otherwise loose scree was a delight. Even if one could climb the lower falls they are faced with an unclimbable Silurain vertical wall. A view of that dry fall from the other side.

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.

I recently went on a trip to southern New Mexico. I made it out to Apache Hill, near the ghost town of Lake Valley and did some fossil hunting in the Carboniferous deposits there. The fossils are in the Mississippian Lake Valley Limestone. Here is a little history about the site: https://geoinfo.nmt.edu/tour/landmarks/lake_valley/home.html I found a lot of stuff, but a few fragments have baffled me. There are supposed to be trilobites found there and I was wondering if anyone could help me identify these remains, trilobite parts or crushed shells? May be difficult as they are just fragments, but any help is greatly appreciated. 1.2.2 2.3 3. 4. 5.

Hi, I'm having a brain lapse and need help identifying the form of iron I'm seeing. Some of the nodules I found seem to have a cubic structure much like standard pyrite but others are perhaps suggestive of hematite in its many crystalline forms? Also, some of the crystals are a glassy reddish color and slightly gemmy in appearance while others are completely black. Apologies for the shots. They were taken outside in a shady area but some of them show a yellow reflectance on the top facing reflective faces. Only the 3rd shot of the black nodules actually has yellowish and red staining. These were found coincident to a formation known as the Sly Gap formation which is a Devonian formation here in southern New Mexico. I believe I recall reading that that formation had nodules like this. The nodules range in diameter from 10mm to 30mm.

I stumbled across this. I can't quite make out what it is so I'm asking for some suggestions. It is rather large at 50mm ( 2 inches) in diameter. Although, I do see crinoids in the rock I don't think this is a crinoid calyx simply because I've never seen one this large in our area or even this well preserved. I'm figuring some other form of sea life but at that point I run out of ideas. Any thoughts? Found in New Mexico, Sacramento Mountains, Pennsylvanian Beeman formation.

A friend of mine in New Mexico has this vertebra in her studio, and asked if I could identify it. My phone charger is 5.5 inches across, for scale. It certainly looks like an atlas vertebra, but I am stumped regarding the species. The foramenae and occipital facets look pretty diagnostic, but my comparative skeletal anatomy is really rusty and I need some help with this identification! It doesn't look like horse, cow, moose, or elk, or mammoth, or mastodon, or ground sloth, for that matter. It is most like Bison bison, but not quite typical, I don't think, but I don't have access to a research collection to compare. It doesn't look quite like the Bison antiquus or latifrons specimens for which I could find pix - looks most like Bison priscus, but that seems unlikely. I don't have the provenance on this. It looks like there was some carnivore scoring perhaps, some weathering, but I'm not seeing butcher marks in my pix. I took quick pix on the fly, not realizing it would stump me! I'd appreciate any thoughts you might have!

Where is the ammonite layer? Windmill Site question.
RockEm-NM posted a topic in Questions & Answers
What layer are the ammonites in, the yellow stuff? And in that Km? I went once and covered roughly the parts marked on your map here in red. I found a lot of the gastropod stuff but not the ammonites.

Would like thoughts on this bone I found in Northern New Mexico, Colfax county, approximately 6,800 ft elevation. Area has lots of remnants of sea shells and marine life. It's concave on one end and convex on the other. I'm also including a photo some of the shell specimens that we're located in the same area. Im always out looking for fossils. I just enjoy exploring and searching for things from the past.Any help would be greatly appreciated.

A surface find in an Upper Cretaceous area of northwestern New Mexico, about 3 1/2 inches tall, 5 inches wide and long.

This is a re-submission of my post from Thursday, Feb. 15, 2024 with the addition of a short video of the specimen. The photos just didn't make as much sense since it was hard to follow orientation. The bone was a surface find in northwestern New Mexico and is about 5 inches wide, and 3-1/2 inches tall. 20240216_133319.mp4

Hi, I'm pretty sure this is a favosite coral but how does one determine the species? It was found in a middle Pennsylvanian formation. I had to leave the base of this coral until I can go back with some tools to hopefully successfully remove it. Measurement is 100mm x 80mm and 70mm tall. Any coral experts out there to narrow this down? Thank you, Kato

Hi, I'm cataloging some finds and would like to learn more about how to identify predation. In the dozens of specimens I have of cordaite leaves from this particular formation, only two have properties suggestive of predation of some sort. The rest are either undamaged or show signs of splitting in the leaves. How do I identify predation? What are the sources of predation? Arthropods? Microconchids? I've searched on google but not found any satisfactory information. Any guidance appreciated! Thanks, Kato I can't find the other half of this split pair currently but the other half is the mirror image of this. I'm thinking this is just missing parts of the leaf due to natural decay processes before preservation.

I was hiking up a ridge between two washes looking at exposed formations for plant and insect fossils in mid-to-upper Pennsylvanian formations. I came across a possible sandstone formation with no evident bed layering. This formation was 1-1.5 meter thick and appears to have plant fragments scattered throughout. Perhaps the fragments are actually the result of this being a high energy deposition area and sedimentation of another type was broken up and preserved in the matrix. Preservation is poor. No evidence of shells of other sea fauna seen in examining the specimens. In the first photo is 'looks like' branching of some type is preserved as seen in the upper middle. The length of that branched object is about 200mm or 8 inches. Branching like this is not something I'd expect for ferns or other plants of the time like cordaites, calamites, etc. Second photo shows larger objects of maximum length 40 centimeters (about 16 inches). The top of the central most piece is what has me thinking this is sedimentation that was broken up and captured in the matrix. There seems to be layering which is not something I'd expect of plants from about 300 million years ago in this area. Again, there seems to be a lot of smaller fragments captured in the rest of the matrix. A 3rd photo showing another object. The lower, larger object suggestive of branching Any ideas of what I might have been seeing? Perhaps some suggestions of what I should try to look for when I cross this formation again? Thanks, Kato.

Hi all, Was wondering if anyone has any ideas on this one. I'm thinking maybe some kind of coral or sponge, but I'm not sure. Found in Truth or Consequences, NM. There are quite a few Pennsylvanian marine fossils in the area. It's pretty heavily mineralized, but if you look carefully at the photo with the scale, there are two dark strands running across the center that are segmented. Thanks for any input!

Found near the Black Range Mountains in Grant County NM. Not sure what it is if nothing but a rock. Was worth picking up either way.

Found in Mimbres Valley near Bear Lake. Not much to say about this piece other than it's odd shape and that it's quite dense for it's size.

Discovered in 2023 in northwestern New Mexico, I found what is believed to be an ankylosaur-type osteoderm. Compared to many other fossils of that type, it is rather small and thin, with a diameter of 88mm X 75mm, and measures 21mm thick from the flat basal surface to its peak on the opposite side. The thickness of the edge is 8mm. The basal surface is remarkable in that it is essentially intact, and displays an intricate web of structural fibers. These photos were referred to a prominent paleontologist in Switzerland who believed the osteoderm may be from an ankylosaurus in the family Ankylosauridae. A local paleontologist was also notified of the find. Any observations or additional information on this osteoderm is invited.

This fossil appears to be a vertebra, and was located as a surface find, possibly in a Late Cretaceous area of McKinnley County, New Mexico (northwest portion of the state). The geological formation is not known. The fossil is hexagonal in shape, and measures about 6.5 cm. in diameter, and 6 cm. thick. Any ideas on the original type of beastie? Thanks.
