  1. Piecing it back together

    Have some nice trackways from the new spot.
  2. Pliohippus horse tooth

    This tooth for sale caught my eye and was hoping someone could help ID it. It was purportedly found in Miocene deposits of Arizona and I _think_ it's a late wear stage cheek tooth of Pliohippus sp. I do not have measurements at this time. Thanks for the help!
  3. Arizona Pennsylvanian Naco fossil

    Hello! Yesterday I did some collecting near Pine, AZ from a site known for shallow water, shelf marine fossils. This is the Pennsylvanian Naco formation. I found something with an odd shape encased in limestone, so I soaked it in diluted muriatic acid over night. I am stumped as to what this might be? Any help is appreciated! Thank you.
  4. Possible tracks in rock arizona?

    Good day all. I'm new here so let me introduce myself. I'm Robert, an amateur gold prospector, fisherman and lots more. I have found nothing too interesting during my gold panning adventures well not for an untrained gold fevered eye anyways but have found tons of modern aged bones that looks old at least a few hundred years old. Anyways now since thats out of the ways I was driving through Arizona when I reached the top of the hill at the sitegreaves national forest sign off of 260. I pulled over to let my semi truck cool down and chose to hike a bit. I sat down on a rock and found a small track. Its not as big as my hand nor is it extremely noticeable, maybe the size of one of those bbq/Chick-fil-A sauce dipping things tad bigger i guess. Anyways I took a picture what do you think? Just an coincidence?
  5. Love my new neighbor!

    My new neighbor (mile away but still the closest) rented an end loader and volunteered to move two of my biggest rocks! Both safe in my collection. And even better, went up the side of the wash about eight feet and found tracks. Could be the edge of the undisturbed fossil layer.
  6. Took some pictures of the chirotherium tracks. Have quite a few with a front and rear together.
  7. This one is too big to move

    8’ long, 32” wide. Excellent sets of tracks. Need a backhoe to move this one. Late in the day so pics are a bit shaded, sorry.
  8. Love this set of prints

    Found this yesterday. It was a bit out of the water flow so it hasn’t been eroded much. Nice distinct prints.
  9. APG Arizona Sponges

    This is a work in progress. I will be adding multiple photos over the next day or so. This is part of my Arizona Paleontology Guide. My collection of Arizona sponges. Self collected unless noted. Actinocoelia maeandrina Finks 1960 Permian Kaibab Limestone Coconino County, Arizona north of Pine. 13 cm wide. link link Other side of Actinocoelia above. Permian Kaibab Limestone Coconino County, Arizona, north of Pine. 13 cm tall. link Chaunactis olsoni Dilliard & Rigby 2001 Pennsylvanian Naco Formation northern Gila County, Arizona 10 cm wide. link Pennsylvanian Naco Formation Roberts Mesa, Gila County, Arizona Sponge is 5 cm across. Link Detail of above Chaunactis. 5 cm. Ensiferites brandenburgi Rigby 1979. Link Devonian Percha Formation Brandenburg Mountain, Pinal County, Arizona 64mm wide. Detail of above. Spicules average 1 mm across. Haplistion sp. photo. Young & Young 1877 Link Stioderma sp. Fink 1960. Link Pennsylvanian Naco Formation Roberts Mesa, Gila County, Arizona 4 cm wide.

  10. More nice prints. One unknown

    Nicely defined toes with claws. I guess you could call them sandy claws. Catch me at your local comedy club! Second picture is taken under a rock I’ve tunneled underneath but I have no idea what the print is from. It’s about 2”.
  11. Alternate title: I found Pennsylvanian fossilized Sesame Wasa Crispbread; is it safe to eat? I have visited the Pennsylvanian Naco Formation east of Payson, Arizona several times this long hot summer and found some interesting sponges. My most interesting find was this 5 cm wide sponge that looked almost exactly like a Wasa Crispbread with sesame seeds on top. I was about to nickname it a Wasa sponge until I found out that it had a genus name: Stioderma. Pennsylvanian Desmoinian Stioderma occur in Texas. Link It is amazing how many fossils I have identified from the Pennsylvanian Naco Formation by reading references from fossils found in Texas and Oklahoma: thanks. link to Collections I found a new 5 cm sponge that sort of looks like a horn coral, but it has spicules. The area contained the usual suspects such as this 165 mm long Wewokella solida Link. and this 50 mm Chaunactis olsoni that the Arizona Museum of Natural History expresses interest in and hopefully will get it.
  12. Skin impression

    Found a messy chirotherium footprint but has skin impression with it.
  13. The summer haul

    One summer, tons of sand and rock and twelve pairs of gloves later. Should have just moved the house to the fossils.
  14. Some new tracks

    Been mostly clearing out sand but did find a nice rock yesterday. Don’t know what the splayed toe print is.
  15. Arizona Coral?

    Hello! While rock hounding in our favorite local spot near Gray Mountain, AZ I found this beautiful coral. The fine details preserved fascinate me- I can stare at this fossil through a loupe all day. Can anyone identify it for me? It was found on the surface, but other marine fossils I have found in the same location have been suggested to be from Permian Kaibab limestone. Our rock hounding site is the tailings from old uranium mines operating in the 1950's I believe. Thank you!
  16. Pennsylvanian Naco Fm. “Wood”

    I have found some Pennsylvanian silicified “wood” from the lower part of the (~207 mya) Naco Formation in Arizona. This is the first recorded instance of likely plant material from the Naco. The formation is all marine in the section that I found it in and has lots of crinoids and brachiopods. One piece has some slight plant like internal texture with isolated circles and curved hash. Photo of side view of 90 mm wide piece with calcite rhomb molds. Most of the wood from that time had distinctive exteriors such as Calamities, Lepidodendron and Sigillaria. Any idea of what my pieces of wood might be? Could they be internal pieces of above mentioned varieties without the distinctive texture? Could it be a tree fern such as Psaronius? @paleoflor Attached picture of single piece on a blue zippered notebook is about 185 mm long.
  17. It's definitely a..thing?

    Look guys I have a... well its definitely a something? Is it a plant, the top of a crinoid, a broken tooth, a really tiny volcano??? No idea. And as a bonus I have no idea where it came from either. It was given to me ages when I was a kid. So if you've got any ideas on what the heck it might be, I'd love to hear 'em! Thanks!
