This is supposably a Dinosaur egg bought in 1982 at "The Arizona rock & Mineral Museum" I think that museum is long gone, but is the Egg real? Its supposed to be a Parasaurolophus egg.

Hi everyone, There is a fossil that was found in a wash at the level of the kaibab formation below a pour over. It was found in two separate pieces. Shortly up the wash is the moenkopi formation and above that is Pliocene to Miocene basaltic rocks. The formation above the kaibab was a conglomerate of many different rocks eroding out of the hill and into the wash. The moenkopi is the most recent formation besides the basalt in that area. I did my best to match the formations to the area, but I am basing my information off the geological maps for the location. The Chinle formation is about the only one I know by sight. Let me know if you need more information. I couldn't find anything other than small marine fossils listed when searching that area in PBDB.

After a one year off for Covid the Tucson show will open the last week of January. Here is a link that provides you info to the +40 venues. Arizona still has high daily Covid 19 cases, so some venues or dealer rooms may require you to wear a mask, be safe. https://xpopress.com/showcase/profile/1/tucson-gem-mineral-fossil-showcase Lots of major changes will occur this year with the location of fossil dealers. The Arizona Mineral & Fossil Show which occupied the Tucson City Center Hotel was moving to the El Conquistador Resort but their web site says this show has been cancelled for the next two years. See Link, something might change as we move closer to the date. If you are looking for someone specifically and cannot find them, contact them directly. https://www.mineralshowslld.com/tucson/ Here are the Key Fossil Venues with a link but most venues have some fossils. The Fossil and Mineral Alley Show at Days Inn Timing: Around Jan 27 - Dealers have individual rooms so the timing will dependent when they arrive and finish setup Dealer Listing: (62 Dealers) I don't see major changes from prior years. Great Fossil Venue (Shark/Dinosaur/Invertebrates) https://xpopress.com/show/vendors/25/fossil-mineral-alley The 22nd Street Show Timing: Jan 27 to Feb 13 Parking is a nightmare and $$ Dealer Listing: Few fossil dealers mostly trinkets https://22ndstreet.show/exhibitor-list/ The Big Gem Show at Tucson City Center (CANCELLED) Timing: Same as the other shows Dealer Listing: Only 32 dealers remain. Only one Fossil Fish dealer, Now mostly Gem and Minerals https://www.thebiggemshow.com/ (Web Page Closed Dec 6) Mineral and Fossil Market Place Timing: Jan 29 to Feb 13 Some dealers have individual areas so their opening may be different (earlier) than posted dates. Dealer Listing: Lots of fossil dealers have migrated to this venue including the Black Hills Institute. Tight dealer quarters and parking but may be one of the better fossil venues https://mfmshow.com/ Mineral Fossil Co-Op Timing: Jan 28 to Feb 13 ( some stores open year around) Dealer Listing: (13 Dealers) https://xpopress.com/show/vendors/44/mineral-fossil-co-op Note: Kendal of Moussa Minerals just let me know of a new tent venue (RMGM Mineral and Fossil Show / Oracle Rd) will set up shop at this location.

Hey there! I was recently given this beautiful chunk of petrified wood. I have found pieces through the years but this is the first I've ever seen with crystals which has intrigued me to learn about them more. I was wondering if this piece is possibly burned wood? It came from somewhere around the Mesa Arizona area I think I'm still trying to confirm that but definitely Arizona. Other then knowing it is petrified wood I would like to hear any info anyone may can give about it.

Hi! Someone directed me to this forum for a possibility of ID'ing these pieces. I collected these loose on the ground the day after a very heavy rain and hail storm, near a wash bed just north of the Whispering Pines area outside Payson, AZ. Someone suggested they might be fossil coral. Any info would be greatly appreciated.

First picture is a clavicle impression which has bone imbedded in the rock. Second is a vertebral or cranial bone. The rest are bone fragments.

I’ve found these rocks near my track fossils and petrified wood. Can anyone shed any light on them?
-
These are a few of the more unusual tracks I’ve found. The tridactyl looking tracks are really interesting since they shouldn’t be here in mid-Triassic. The one that looks like a human foot is particularly creepy

IMG_2038.MOV Here’s a video of my collection as of May. I numbered them a while back and got to 185. That doesn’t include the trackway pieces or what I’ve added since then. It’s been almost exactly two years since I found the first track. Not bad for a sixty year old guy working alone lol.

I have found many Pennsylvanian sponge roots in an isolated area of the Naco Formation near Payson, Arizona. The sub parallel root fibers range in size from 0.2 to 1.2 mm in diameter. The roots are often found growing/covering crinoid columnal sections. Near Pine and at my site the roots are found where Chaunactis olsoni sponges are the most common, but not the only sponge species present. Now I need to find a sponge with roots attached to ID the species of the roots. It is unknown if the silicified roots were originally silica or calcite. I noticed that there are grooves from and matching the diameter of the roots in originally calcitic crinoid columnals and head pieces. What caused these grooves? Two hypothesis: the silica roots grew over the softer calcitic crinoid pieces rubbing grooves into them as the currents caused the roots to sway. Second: the roots had living tissue on the outside that secreted acid that caused the grooves. Knowledge of extant sponge anatomy might help answer this question. Photo 1: average root diameter about 0.6 mm. Photos 2 and 3: detail of first photo. Photo 3: roots growing around section of crinoid columnals with grooves in columnals. Dilliard, Kelly & Rigby, J.

Hey y'all! I'm Sheena and I'm a newbie to the fossil world, I'm big into rock hounding and mineral hunting. I live in Globe, Arizona and my backyard is a playground full of rocks, fossils, minerals! Cant wait to read up on y'all's finds and learn more about the fossil world.
-
hello everyone, I'm a newbie here and with fossils and hoping y'all's experience can help me out...I live in Globe, Az and I find some awesome rocks and minerals...however I know nothing about fossils...I found this HUGE rock last year and everyone that see's thinks it might be fossils? I do know the area was underwater "back in the day"...so we have lots of limestone conglomerates that formed. The first picture is of a oval shape something that might be a fossil... it's roughly 4" by 2" width. It has lots of texture to it. The parts I'm asking about that might be bone fossils is at it's tallest is 1 1/2 foot tall and roughly 4-5" wide at the top. There are two of the "bones" one in from of the other and they are the same shape and size. The rock itself is roughly 1 1/2 by 1 1/2 feet tall/wide Weighs roughly 150 pounds. Thank you in advance for help! Sheena Globe, Az.

Crania Crania modesta is a rare calcium carbonate Pennsylvanian inarticulate brachiopod. The shell is very thin and the ornamentation of the shell below shows through. You can see the interior of a near circular 4.6 by 4.8 mm pedicle valve that attached itself to aLinoproductus prattenianus (photo #1). A bryozoan also covers the front and back of the Linoproductus (photos #2 & #4). Photo #2 is a different photo of the same Crania as in photo #1. The Crania has a thickened rim and a sub central knob. Rowell (1965, p. 289) lists Crania as the only Pennsylvanian genus with a calcified pedicle valve as stated by Sutherland (1973, p. 16). The presence of a large bryozoan colony on the backside of the Linoproductus valve (photo #4) suggests why only the pedicle valve of the Crania was preserved. The entire Linoproductus shell with the Crania and small bryozoan colony on top (photo #2) was flipped over allowing the bryozoan to grow on the other side. The brachial valve dissolved away or was broken off from exposure before it was buried. The brachial valve was probable very thin like the pedicle valve. Taxonomy from GBIF.

Hello wonderful fossil-people! If you and you're gang enjoy solving a groovy mystery, I have a post for you! This rock was found in an area of Northern Arizona that is very well know for producing lots and lots of bryozoan, brachiopod, and crinoid fossils, as well as crystals and geodes. The bit of rock in question was found in the side of what appears to be a broken geode. There is a triangular fragment of stone that does not match the material surrounding it. There is also a white discoloration encompassing the triangle that I've highlighted in green on one of the photos below. The colors in the 3rd photo are a little more true to what it looks like in real life. The geode is kind of a pink-ish color and the triangle "fossil" is a dark brown/reddish color. Given the abundance of marine fossils found in the same location, I wonder if this is also fossil. It just seems so out of place in this rock. I have oodles of bryozoan, brachiopod, & crinoids that I've found in the same location and I can share pictures of these, if it somehow helps So what do you think, fossil or random bit of stone? If it is a fossil give me your best guess as to what it might be... or even give me your worst guess. I'm not picky lol.

This silicified lacustrine Miocene stromatolite is a trace fossil made by a gram-negative photosynthetic blue-green bacteria. The originally limestone stromatolite was formed as a bacterial mat trapped sediment and precipitated limestone as it grew from the lake floor towards the sun. It shows classic convex layering towards the top. The stromatolites occur in tuffaceous and lime rich lake sediments that might be part of the Chalk Canyon Formation that is bounded on the bottom by basaltic lava and volcanic rich conglomerate and sandstone on the top. Locally numerous silicified casts and molds of reed like plants, their roots, and palm wood occur in the lacustrine sediments. Since the area is under possible scientific investigation I will not give a more specific locality. The Arizona Museum of Natural History has fossils from the site per my showing them the site. The taxonomy is very unsettled as is the author of Cyanobacteria.

While removing an unknown sponge by acid dissolution from the Permian Fort Apache Member of the Schnebly Hill Formation from northern Gila County in Arizona I found several silicified brachiopods with spines. Several Bellaclathrus spinosus brachiopods were present ranging from 0.75 to 1.5 inch across and had spines as long as 1 inch. The pedicle valve of the brachiopod in the first and second photos is about 1 inch wide not including spines. This is the finest specimen with spines that I have found. The third photo shows the brachiopod attached to several others of the same species. Fourth and fifth photos are from Winters 1963 reference below.

Several days ago I ventured to a Devonian desert locality near Superior, Arizona. I found the largest fossilized coral colony that I have ever found: 2 ft across. A giant Iowaphyllum nisbeti coral was covered over it’s entire length with several inches of a stromatoporoid sponge. I should have taken a photo, but it was not very photogenic; it looked like a white ledge in cross section. First photo is a piece of light colored Iowaphyllum nisbeti coral covered with a medium gray calcitic stromatoporoid coral that is about 8 inches across. The top of the coral is pointed up. The second photo shows a detail of the stromatoporoid with horizontal layers and faint vertical pillars Nearby I found a partly silicified stromatoporoid 5 inches across that may be the same as the one mentioned above. This is probably the best hand sample of a stromatoporoid that I have found since the vertical pillars are so prominent. Only about 20% of the pillars are easily visible. Pillars differentiate stromatoporoid sponges from stromatolites which show only horizontal (to the growing direction) layers. See up close section of the stromatoporoid in the last photo.

Hey guys! I’m going to be in Arizona for a few months and need to get my fossil hunting itch scratched! I’ll be viewing the petrified forest (and not taking anything of course), but I wanted to know where I could go to find some fossils. I will be getting a permit. As someone who hunts heavily in Florida I can’t wait to see the difference in Fauna and age in Arizona! let me know what you all recommend.

This dolomite stone was discovered near Chasm Creek, central Arizona. It appears to have the fossilized impressions of raindrops splashing into a fine muddy surface. The stone seems to be dolomitic, as HCl causes a low fizz, unlike typical limestone's more energetic fizzing. Most of the "splashes" have the central "rebound" splash seen in my high-speed imagery of water droplets. That central rebound appears to have been broken off over time. Does my assumption that this is a somehow frozen-in-time rain shower make sense?

Three of my family members found this footprint in Lake Powell, Arizona last October 2020. They differ in what they say the size is from 4 to 12 inches, but my husband is probably the most reliable measurer and saying 12 inches. They looked for more quickly but did not see any. The photo of scenery has a person in a white shirt in the upper central middle in the shadows it was right there or right below there where they found it. A university professor has said it is prehistoric. I did minor searching for clues and the only thing I have so far is it may be a therapod (dilophosaurus?) from the Kayenta formation. If we had to take someone to the exact location that is possible. Thank you for any input....
