I found this recently north of Hatch New Mexico. I was picking up lots of small quartz crystal clusters and thot this was maybe a cluster that got sheared off somehow. After a closer look and bit of a clean up I noticed the side views look like there is “stacked” formations. So the top has the hexagonal shapes and the sides look as if there is fairly uniform segments. The same general area has fossils like fusilinids, crinoid bits, shells at different levels. Also in the area rhyolite, chert and quartz crystal. Anyway, not sure if this is a fossil of some sort but have never found anything quite like it. PALEODICTYON is what came up when I googled hexagonal fossil. Certainly some similarities. Thanks for any help u can give me!

Hi everyone, Im new to the forum and fairly new to New Mexico fossil hunting in general. I moved to Albuquerque about two years ago to take a job as a conservation biologist here at the ABQ BioPark, and have been exploring this awesome state ever since. Just wanted to say hi and meet the local fossil hunters in the area!

Hey folks, Here is a bone I found today. The photo shows it in situ as it was slowly sliding down a slight grade. The area where it was found does not permit collection by citizens so it remains where it was found. The area where it was found is along the ancient shoreline of the Western Interior Seaway on the west bank where the shoreline ebbed and flowed to engulf the immediate area, only to later be dry land at essentially the same level of strata. In the same immediate area where this was found, also today, I located fossilized stromatalite (a water bacteria), and fossilized wood. Within just a dozen miles of the area where I found the bone there have been collections of bone specimens ranging from mosasaurs to plateosaurid-type dinosaurs. Hopefully someone has an idea about this bone to enlighten someone who really doesn't know anything about it, namely, me. Location where it was found is in the San Juan Basin of San Juan County, New Mexico, Kirtland Formation, Upper Cretaceous period.

A new domaeosaurid, Dineobellator notohesperus, consisting of a partial skeleton from the Upper Cretaceous (Maastrichtian) of New Mexico, the first diagnostic dromaeosaurid to be recovered from the latest Cretaceous of the southern United States. The holotype includes elements of the skull, axial, and appendicular skeleton. From the Ojo Alamo Formation Dineobellator notohesperus Article https://phys.org/news/2020-03-feathered-dinosaur-surviving-raptors.html Smithsonian Mag.

Friends, I seem to collect lots of petrified wood in my nearly-every-weekend outings into the oil patch in the county where I live. Much of what is found are small little bits and pieces and a whole lot of it is really pretty. Some I will try to identify and those may earn their own topic entry, however, others are just nice little pieces that I cut up on my saw and will post the photographs here for y'all to look at. They are just too pretty to not share, you know? All those entered under this topic will be found near my home unless otherwise notated. Some of the petrified wood will have been found by a buddy of mine whose rock I cut up for him from time to time, and those will also be notated here. If no one minds, I probably won't put a scale on the specimens since all of them will be no longer than 4 1/2" on their longest side since that is as wide as my little rock saw can handle. As usual, feel free to comment. Some of this stuff might really challenge your ability to readily recognize what is or what isn't petrified wood.

For your review, here is a specimen of Palmoxylon, sp. (a fossilized extinct palm tree) found in March 2020 in the San Juan Basin of San Juan County, NM. The area is within the Kirtland Formation, Upper Cretaceous Period. This specimen has been cut to show several views of a transition zone in the root ball where adventitious roots or Rhizopalmoxylon, sp. emerge. The first photograph has been diagrammed to show several features in the transition zone. I have also submitted photos of this specimen in the March 2020 "Find of the Month" contest, and a more complete description of the specimen has been made in that entry.

I found these concretions a couple of days ago. I'm not sure if the small hollow concretions were formed in the same way as the larger ones but they were within about 50 feet of each other. The small hollow concretions shown were up to ping-pong ball in size. The larger ones are shown with a scale. Found in northwestern New Mexico, San Juan Basin, Upper Cretaceous, Kirtland Formation.

Good morning folks. I purchased this box of coprolites many years ago under the description "Triassic carnivore fossil dinosaur coprolite, New Mexico". Did I do good or did I get taken?

Here are some more photos submitted for your viewing pleasure. The specimens aren't all rocks and minerals, per se, since three of the five are petrified wood. I haven't researched the PW specimens in an attempt to determine the type of original wood. All were found by myself or a running buddy within the past couple of weeks. The area found was in San Juan County in northwestern New Mexico, Upper Cretaceous, Kirtland Formation on B.L.M. land. The second and forth specimens is a type of brecciated agate / jasper mix I call New Mexico Brawn. They were found in the same area but were colored so very differently from each other. The first, third, and fifth specimens are fossilized wood. An interesting thing about the first specimen is that it is uncut and just as I found it, with agate almost as clear as glass. Hope you enjoy looking at these.

Some petrified wood found in northwestern New Mexico, San Juan Basin, Upper Cretaceous, Kirtland Formation a couple of weeks ago. The cut slabs are from a log about 6-inches in diameter and my best guess is conifer only because most everything else in that area turns out to be conifer, specifically, Cupressinoxylon sp. Any other opinion about species would be welcome. There are several nice agate bands running through the length of the log and are clearly visible here. The first slab is dry and the second is wet.

MYSTERY SOLVED! Please see post below. Found in northwestern New Mexico about a week ago. Size is about 10 in. X 8 in. X 5 in. It looks like a rock with linear crystals embedded it in, however, the close-up photos shows the entire specimen is made up by layers and layers of the linear crystals, I'm guess to be some sort of chalcedony because of the waxy-feel. I just haven't seen a crystal matrix of this type in the area where it was found.

A couple of photos showing an unknown fossilized conifer tree located this past November (2019) in northwestern New Mexico, Kirtland Formation, Upper Cretaceous. Sorry for no scale but the specimen is about 13 inches (33 centimeters) long. Also included is a photo of my dig where I removed this specimen as a piece of something larger. You will see this specimen limb is quite compressed, something common for petrified wood found in that area of New Mexico. I have tentatively identified the specimen as a conifer using a DinoLite (see photo). I am seeking help with additional information or identification beyond it being simply "conifer".

I'm piling back in late from a fossil hunt and wanted to get this online. Found in a lower Pennsylvanian formation locally. Typically find cordaites and ferns in this formation. Today, this odd split pair caught my attention. For size reference the small calamite next to the split pair is a little over 5 cm long and 2 cm wide. Although not a great field shot I'm posting it up now in case someone can point me in a solid research direction. Part of me thinks cordaite but the unusual branching features on one side only are quite odd to me. Perhaps some sort of rhizomic structure? I will post a close-up tomorrow when I have access to natural light again. Thanks for any advice or suggestions, Kato

A couple rocks found over the weekend in northwestern New Mexico. Sorry I didn't scale it, but both are about 3-inches wide. Thought I'd share. Any comments welcome.

Out of over 17,000 teeth pulled out of ant hills in north central New Mexico, I came up with this one isolated tooth. There are a scattering of other hybodontids in the fauna, but this is the only one of this kind. I originally thought this was Polyacrodus parvidens, but upon getting into the literature I have discovered that this species has a high central cusp and the ornamentation isn't as strong as that on this tooth. So now I am leaning to P. cf. brevicostatus, and if this is the case, would be one of the first examples from this state. Any ideas from all of the distinguished people on the Forum?
