  4. Bryozoans

    Here are a few pics of the bryozoans I cracked into today. Experimenting with the camera, hope they come out OK. (will delete some if necessary) You may see more detail by saving and zooming in ..... not sure. Thanks for looking, Enjoy.
  5. Hi Folks. Anxious for the rain to quit so I can start digging again. Took a walk through the garden patches and picked these up today after several nice "rinsing" rains". I hope to find more of the bryozoan plates, maybe more larger ones. Maybe you can see more than one variety in the attached pics. More to come .... I'm hoping. Kind regards,
  6. Well-preserved bryozoans

    Hi everyone, I find this tiny but well-preserved encrusting bryozoan sheet: Same piece includes not so well-preserved branching bryozoans: I understand species ID is likely impossible without more magnification, but I will be very thankful for any guesses about their order, family or genus. Maastrichtian strata, Catalan Pyrenees.

  8. Last week I drove out to Kentucky to spend a week with my family. Of course I also hit the fossil beds. The first day I visited the two Mississippian sites- Wax and Leitchfield that I visited last year. Here are some of the highlight finds of that day. First- Wax: Blastoids and bryozoans:

  10. Marvejols fossils

    Hello. 2 years ago i got box with fossils described as Fossiles U.S.W Marvejols. I didn't get any more info about them. For me fauna looks Devonian Frasnian. Most of fossil sites in the area are Mesosoic. First specimen contains 3 different corals.( Alveolites ,Aulopora and Thamnopora ??)
  11. Hello everyone! We just finished our study of the diminutive bryozoans we found in the Fort Apache east of Payson along the Highland Trail. As expected, they are all very small indeed and tell us once again that the environment they lived in was a stressed and sediment filled sea bottom, with little escape from the huge clouds of silt and sand raining down on them constantly. Thanks for looking, and it is with great pleasure we share this write up with you! (Adapted from our Paleo web site) For the amount of Limestone we have dissolved - now in excess of 200 pounds or so, it was surprising to only see about a teaspoon of bryozoans show up the acid fines. But this is an additional clue to the conditions which deposited the Fort Apache Limestone. As noted from write ups on previous batches of material, the amount of sand and silt mixed in with the limestone was a whopping 10%. The source of course was the Sahara like dune complex on shore with its blowing winds and large amount of muds and silts washing into the sea. The dune complex is now lithified into the adjacent Schnebly Hill formation, and forms the gorgeous Permian red buttes seen in Sedona and surrounding areas. Great for scenery, but at the time, bad for the marine fauna which had to deal with large amounts of sediment always raining down on the ocean bottom. This explains the almost complete lack of certain fossils, such as crinoids, brachiopods and corals. These invertebrates cannot tolerate large amounts of sediments raining do on on them as it clogs their filter feeding apparatus, and will not be found in such areas. Bryozoans were also filter feeders, and they are very limited in this formation, as are sponges. We encounter three types of small bryozoans in the acid fines from the Fort Apache. First, we have a branch or twig like diminutive bryozoan with extremely small pores over its surface. These are some of the smallest bryozoans we have ever seen! Second, a larger zooid type that encrusts shells and urchin spines. These have excellent detail in each zooecium. (the body chambers for each animal) And finally, fan shaped fenestrate bryozoans can be found in small broken pieces. These net like "moss animals" have some very nice fine details in the fan segments. Only a half a teaspoon of those were found, so are quite rare. Here are some representative images of the bryozoans we have found in the Fort Apache Limestone, with magnifications that vary from 7x to 45x. Fenestrate bryozoans - 7x. These fan shaped colonies were always found in tiny centimeter or less sized fragments, and never larger. But they have excellent surface details on the zooecium side. Closer view, with pin head at bottom for scale. 45x view showing small tube like pouches which contained individuals. These small tube like chambers are called zooecium in fossils and cystid for still extant living species. Every small branching bryozoan we found can fit in a half a teaspoon. Some have Y shaped branching, others are straight or tapered. A pinhead for scale is at the bottom. Some of the smallest members of this type seen here. Millimeter scale at bottom. 45x view of individual with very tiny pores. The third type was a more robust larger encrusting bryozoan. This one covers the exterior of a broken urchin spine. Millimeters at bottom. An urchin spine with a bryozoan partly encrusting its surface. The largest encrusting specimen was stained red by oxides in the silica. Encrusting type over a spine, showing detail in the zooecium. Thanks again for looking, we are now starting work on sponges we found, a very few of them, but they are spectacular in micro details!

  12. Hey there! I'm sorry its been so long since I've posted on here but suffice it to say I need your help. I'm planning a six to seven day fossil hunting trip in Pennsylvania (sometime in mid august) and I need your help verifying that the sites I've picked to visit from Robert Beards guide Rock Hounding Pennsylvania are still accessible to collecting as well as coverable given my time frame. The places I'm looking at hunting are sites 27. Beltzville State Park (Outcrops on shoreline), 28. Lehighton, Lehigh Canal (Former borrow pit and outcrop),30. Deer Lake (Borrow Pit), 33. Suedberg (Outcrop in former borrow pit), 35. Centralia (Former strip mine outcrop), 38. Rockville (Former quarry), 48. Walker Lake (Hillside and unpaved road), 51. PPL Montour Preserve (Hillside, Former borrow pit), 57. Uniontown (Former quarry). Any insights as to whether or not theses sites are still accessible to collecting, weather our not you believe covering all these sites within 6 to 7 days is possible, and any other tips and tidbits of information on the sites, and or planning a large trip like this etc, would be greatly appreciated! When I go I'm planning to take notes and pictures and then, when i get back, write a few essays illustrated with pics that I will post on here! Thank you in advance, Glenn aka Fossil123
  13. Coral/Sponge ID from Central Texas

    I don't mean to overkill with ID questions ha. Haven't quite been adjusted yet to a forum group that is actually rich with knowledge. I have so much to learn, really stoked this exists. Anyways I found the left item from Walnut Creek in Austin. The rock to the right came from the Pedernales river from a gravel pit.

  18. From the album Middle Devonian

    Palaeozygopleura hamiltoniae (gastropod partially encrusted with a bryozoan) Middle Devonian Moscow Formation Windom Shale Hamilton Group Deep Springs Road quarry Lebanon, NY. Usually these are completely enveloped by the bryozoan. First time I've seen one only partly encrusted.
  19. The weekend of June 24th and 25th I participated in an outing with the New York Paleontological Society led by my friend, Ray McKinney to Brechin, Ontario. TFF Member Malcolm led our group into the James Dick quarry where both Bobycaygeon and Verulam Formations are exposed. These are Middle Ordovician from the Trenton Group and contain a wide variety of invertebrate fossil fauna. Also met other TFF members Kevin (Northern Sharks) and Joe (crinus). Most of the quarry is the Bobycaygeon and the very top is the Verulam- only accessible near the entrance, but I got some excellent well preserved matrix plates from there. I spent the second day combing the spoil piles. This first picture is Lake Simco by Beaverton where we stayed. Malcolm in the middle, explaining the quarry geology to NY Paleontological Society members.
  20. To begin with I am not an Ordovician collector, but after seeing recent posts from other FF members, I decided to stop at the St. Leon and Lawrenceburg road cuts in Southern Indiana as I was making my way to North Carolina. I will post picks without specific ids, I know I have bryozoans, brachiopods, horn corals- but no trilobites. I did find 3 things that look to me to be possible Cephalopods, but could be mistaken. I also found 1 other item that I have no clue to its I'd. Any help with these last 4 items would be appreciated.
  21. Bryozoan? Coral? One or two species?

    I found several mixed pieces last weekend while out in southwest Virginia; bits that had tumbled down the hillside and into the road. This was along a road that follows the Holston River, in mostly limestone/shale. One piece was filled with crinoids (stems), from tiny to pencil diameter; one had meshy bryozoan pieces and brachiopods, then there was the piece that had this. Please bear with me, I've looked online, and in my books, but since I have no idea what I'm looking for, it complicates things, and I want to learn. In both examples, the coral-looking chamber/pore sections are alongside the mesh/bryozoan-looking sections, so I'm not even sure if I'm looking for one, or two separate, organisms. I'm sure whatever it is, it's probably very common in this area, but if someone could help ID it so I'll know next time, or at least point me in the direction of what I need to research, I'd be grateful. Thank you!
  22. sponges ?

    Hi, i come back to you again because i tried to figure out what might be items i found in the Senonian of Touraine in France without success. Most of them, i believe are sponges. 1) about 3,5 cm round
  23. This is my first trip report on the forum, an attempt to organize my finds and hopefully get some help with identification. The quarry was located near Rockford, Illinois, Ordovician period. Recepticulites, in the field. Not sure what this impression is. Any ideas? An assortment of brachiopods and gastropods in beautiful bone-white chert. Not sure what this is...sorry for the blurriness, my phone doesn't have the best camera. Gastropod and recepticulites chunk Top and bottom halves of recepticulites. Not sure what these tentacles are... Bryozoans perhaps? Here they are under the microscope. They appear golden only because I naively used a brass brush to clean them (oops!)... a nice effect nonetheless.. Thanks for looking!
