Here are some more Miocene plant fossils from lake sediments north of Phoenix, Arizona. The first large piece of brownish chert, a lemon, had poorly preserved stems. Because the lake sediments had abundant uranium, the rock glowed bright lime green under short wave UV light. Organic matter often attracts uranium deposition.The second piece in the third photo has a great impression of plants that looks like it could have been created in fresh concrete yesterday. Field of view in all photos 6-9cm long.

This is a partial vert from the Fort Crittendon Formation, Old Santa Rita Mountains, Arizona. Anything diagnostic enough to tell what species or family this belongs to?

I found these in a Miocene lake bed formation northeast of Phoenix, Arizona. The lake beds are deposited along with volcanic rocks and are probably part of the Chalk Canyon Formation. The lake beds have pieces of agatized plant material. Any ideas of what the plants might be? I am especially interested in the molds of a jointed plant shown in the first three photos. @paleoflor Photo about 6cm high. Detail of first photo. Filled center of plant stem ~0.7mm. Depressed mold of stem ~ 3mm across. Height of photo ~2.5cm. Detail of first photo. Center of stem ~ 1mm. Mold of stem ~3mm across. Length of stem ~5.5cm. Bunch of stems average of 5mm across. Cross section of above photo. Typical stems each about 2 - 4mm across. Possible stromatolite/algae structure.

I will actually be moving out west in June/July, I’m currently researching the areas. I’m calling on the experts to let me know which is the best move for fossils. I’m a geology grad with a desire to pursue paleontology, so career opportunities must be kept in mind as well. The three cities we’ve narrowed down are Fort Collins CO, Flagstaff AZ, and Bend OR. Don’t worry, I will be bringing a plethora of Florida fossils with me, so, whoever gets to meet me will have plenty of gifts and goodies. Just looking for some solid advice. ps, sorry for being so absent on the forums lately; life has been a little cray!

Is this possibly stromatolites? Found just north of Golden Shores, Arizona, in a dry wash in loose material on the bank of the wash. Thank you for any help, very new to collecting fossils.

Here is The Association of Applied Paleontological Sciences online guide for fossil dealers and other paleo related info for the 2019 Tucson (Arizona) fossil, gem and mineral shows. The guide lists dealers by speciality and venue. The guide has some blank pages (advertisements missing?). https://aaps.net/pdf/2019-AAPS-Guide-final-lo-res.pdf

Here is a fantastic example of a calcareous rock (possible Mancos Shale) from NE Arizona (Black Mesa) that I obtained from the teaching collection of a retired geology professor. The whole rock is about 6 inches long. Can anyone guess what it is and why I like it? Can you make a good guess @FranzBernhard?

Hello, I joined this group today so that I might have a recent find identified. My name is Larry Atkins and I'm a meteorite hunter from Michigan and I spend a lot of time in Arizona looking for space rocks. I find a lot of different things out there and yesterday I found an interesting cluster of fossil bone and teeth. Last spring, in the same wash, I found a partial skeleton of a huge tortoise. The Arizona Museum of Natural History was supposed to dig it up but they never got around to it and the monsoons have apparently washed it away! So disappointing. Here's an in-situ of yesterday's find. This is in Pinal county AZ. Thanks! Larry

If anyone is familiar with Permian tracks, can anyone ID these? All I can tell is that they appear to be synapsid tracks, but not Dimetrodon. I'm assuming that means Edaphosaurus is out too, but that's all I can figure. the ONLY details still known are that they're Permian tracks from somewhere in Arizona. There's no more information available. There's 4 plates... 1-pic 1 2-pics 2,3,4 3-pics 5 4-pics 6,7

Hello, I am glad I found this forum; recently I purchased several acres in northern arizona and I found a few rocks/fossils on my land that I was hoping someone could help me identify. Any idea or suggestion is appreciated. Thank you 1st fossil/rock of 3

I found this in a fossil bed along with some clam fossils I was finding near Globe, Arizona. It was sitting in a depression on the ground near an exposed limestone fossil rift. The white band goes all the way around symmetrically and the rock type does not match anything in the area. is it a fossilized turtle shell, or nut maybe? or an indian artifact, or just an out of place rock?

You, the members of The Fossil Forum, inspire me. Keep up the good work.

Found what may be a vertebra, sticking partially out of the ground on private property near Phoenix, Arizona in Maricopa County. The soil is hard-packed coarse sand/silt/gravel with areas of clay. A landscaper added a top dressing of decomposed granite and river rocks - a typical desert landscape design around here. The specimen likely was transported to the site in the river rock. Luck me! Other fossils found in the landscape material lead me to believe it came from a healthy and diverse marine environment with turtles, fish, shark, crocodilia, lizards, skate, snakes and mammals. The entire area was once an inland sea. The specimen is approximately 6.5 cm length x 5 cm width x 2 cm height. (Lateral measurement varies from 1.5 cm to 2.5 cm.) The vertebral body is 5 cm length x 4 cm height. Let me know what you think. The "tooth" on the distal side measures 2 cm.

The corals from the Pennsylvanian Naco Formation in Arizona have not been officially described partly because many are silicified and have lost internal details. Any idea what these corals are with central columns that are vertically striated? Their average length is 2 to 3 cm. I think that they look like Lophophyllidium. Thanks, John

Hello, I have been buying some fossils not knowing what they might be. The seller did not know either. It will be a learning experience. Thanks

EDIT: see complete post below Ynot's brief post. I found some amazing fossils last weekend north and east of Payson, Arizona in the Pennsylvanian aged Naco Formation. Clear skies and warm temperatures were tolerable because of the tree cover. The star of the show was a 40 cm slab with and upside down silicified Syringopora coral colony that showed the basal branches. Mother Nature started the etching process, I continued it with dilute pool acid. For scale, each coralite is about 2mm in diameter. The next star was a 23cm unidentified sponge.

Hello Everyone, My name is Alan, Recently I purchased several acres in northern Arizona and on my land I have been finding several interesting rocks, and fossils. I have always been interested in paleontology and geology but I have no formal education on it. That in mind I will be posting photos of different rocks and fossils I find on my land and any suggestions or ideas of what they maybe are greatly appreciated. Thanks everyone. Alan

Hey all, I have posted a few times and figure I might as well introduce myself. My name is Jeff and live in Arizona. I actually started collecting fossils to make a small display case for my nephew for when he is old enough. Just a baby now but it's never too early for an uncle to start spoiling his first nephew. Anyway, now I really enjoy it and with all of the Jurassic World and The Meg movies coming out it's really interesting to not only know but too truly understand what is creative entertainment and what is/was reality. Anyway glad to be a part of the forum and hopefully learn much more.

Anyone know what this Pennsylvanian (Desmoinian) shark tooth from Arizona is? The tooth is 40mm wide and 30mm from top of tooth to bottom of preserved root. The shape of the tooth suggests that it was a shell crusher. Thanks, John

Here are photos of two trips taken to look for Paleozoic fossils in northern Gila County in northern Arizona. Daily thunderstorms and plentiful shade made the 90 deg. + temperatures bearable. I ran into TFF member ArizonaChris while in the area. In the Martin Formation I found interesting stromatoporoids, now determined to be sponges, that were important reef forming organisms during the Late Devonian. Pine needles for scale. Here are some silicified Martin Formation brachiopods. Nearby are many caves and sinks in the fossiliferous limestones of the Martin and Redwall Formations: up to 100 miles of passages according to a caver. The first one is full of junk metal including two cars. Any idea what the cars are? Here is Tin Can Sink. To be continued.

Here is a cool photo of a silicified Michelinia coral that I was trying to extricate from Redwall Limestone with acid. It reminded me of my proposed TFF slogan/motto: "we place fossils on pedestals".

What are the plants in the photos from the Pennsylvania/Permian boundry from the Schnebly Hill Formation near Payson, Arizona that I am linking to my Arizona Paleontology Guide? Photos are from geology teacher Stan Celestian and were not found by me. (I'm going to look at the location for plants). Thanks, John 1 Annularia? 2 Fern type? 3 Fern type?
