  1. Arizona sponge

    I found part of a sponge from the Pennsylvanian Naco Formation. The sponge is 5 cm in maximum width. The needle like structures average about 0.2 mm in diameter. Are the needle like structures part of a sponge body or part of the roots? Species? A cross section shows the needles radiate from the center. Photos: 1 top 2 bottom 3 cross section 4 detail
  2. Arizona Pennsylvanian Coral

    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
  3. 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 skys 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.
  4. Any idea what these silicified possible crinoids are? Are they even crinoids? They are from the Pennsylvanian Naco Formation from near Payson. The ones in the photos (both sides are shown) are from 0.8 to 1.5 cm wide. @crinus These two references might be of help. Anyone have access to the photos from these? Webster, G., & Olson, T. (1998). Nacocrinus elliotti, a New Pachylocrinid from the Naco Formation (Pennsylvanian, Desmoinesian) of Central Arizona. Journal of Paleontology, 72(3), 510-512. Webster, Gary; Elliott, David. (2004). New information on crinoids (Echinodermata) from the Pennsylvanian Naco Formation of central Arizona. The Mountain Geologist. 41. 77-86.
  5. Paleozoic Adventures in Arizona

    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.
  6. Arizona Sponge

    I found a sponge in the Pennsylvanian Naco Formation north of Payson, Arizona. It may be the same species as an earlier find although instead of pancake form it is a conical form: http://www.thefossilforum.com/index.php?/topic/82186-knocking-about-the-naco-pennsylvanian-sponges-and-corals/&tab=comments#comment-871386 The first photo is of the convex outer surface. Part of top is broken off. Longest length of the sponge is 8cm. Any ideas as to identity? @Arizona Chris See photos in additional posts since I am doing this on a phone and cannot reduce file size.
  7. I am preparing a plate from the Upper Pennsylvanian Naco Formation, in Southern Arizona. I think I may have found part of a trilobite, among all the brachiopods. Does anyone have a clue as to the species? I really can't find any info on trilobites in this formation. The locality is definitely not known as a trilobite-collecting one.
  8. Lack of snow cover and warmer than average temps allowed me to explore and collect sponges and corals from the Pennsylvanian Naco Formation in central Arizona, north of Payson. Widespread chert of the Beta Member suggests that silicious sponges may have been common. Several have been identified but many more exist. I have seen and collected several undescribed species. Dilliard and Rigby have described several sponges including Chaunactis olsoni which I found in the area: The New Demosponges, Chaunactis olsoni and. Haplistion nacoense, and Associated Sponges from the. Pennsylvanian Naco Formation, Central Arizona. by DILLIARD and RIGBY http://geology.byu.edu/Home/sites/default/files/geo_stud_vol_46_dilliard_rigby.pdf EDIT: geo_stud_vol_46_dilliard_rigby.pdf Photo 1a. Detail of undesribed sponge. Marks are 1/16th inch. Any ideas? Photo 2. 3/4 quater view of sponge in photo 1a. Note red 1/3 to 2/3 inch thick pancake-like form of sponge. Photo 4. Top of another similiar sponge. Marks are 1/16th inch. Help me ID 2 corals and one sponge. Photo 3. Coral, Multithecopora?, which has been reported from the Naco many miles to the south. Photo 5. Probably Chaetetes, a side view. Photo 5a. Top of Chaetetes. Photo 6. Horn Coral, Zaphrentis? 1a.docx 2.docx 4.docx 3.docx 5.docx 5a.docx 6.docx
  9. Sponge ID

    What type is this sponge from the Pennsylvanian Naco Fm. from near Payson, Arizona? The silicified sponge is about 1.5 to 2 inches across. Was it originally a silicious or calcareous sponge? Does anyone know of an expert who is interested in undescribed sponges from Arizona/USA? I know of at least 3 other undescribed Arizona sponges. Thanks, John
  10. Horn Coral with?

    What is the net like pattern that sticks-out on the inside and outside of a silicified Pennsylvanian horn coral from NW of Payson, Arizona? Could it be an epibont-sponge? Could it be silica that filled cracks in part of the coral that was not silicified and eroded away? The coral opening is about 2.5 inches across.
  11. Naco Fm. fossil

    I found this "spiky head" chert fossil in Pennsylvanian Naco Formation Limestone NW of Payson, Arizona near Pine. The "head" is about 1/3 inch across. Is it a crinoid head without arms, what kind? Thanks, John
  12. Articulate Brachiopod

    This is a common brachiopod found in the Naco Formation Limestone that crops out below the Mogollon Rim in central Arizona.
