  1. Back to the Ohio Valley

    Hi Everyone, I took a 2 week trip to the Ohio Valley, arriving back in New York about a week ago. It was primarily a family visit since many of my relatives now reside in the Elizabethtown, KY area. However, the Ohio Valley, as some of you know, is very rich in Paleozoic fossils and I just had to make a few stops on my way there and back as well as between family engagements. I will try to share enough to give you all a gist of it: It was a long day's drive from the northern suburbs of New York City to Richmond, Indiana where I spent the first night. The next day I was headed down State Road 101 to Garr Hill, to collect in the Upper Ordovician Liberty Formation. It was my first time at the site and everything I found was collected from loose rocks at or near the base of the outcrop. A couple of pictures:
  2. Went to Joshua Creek near Mississauga and got bitten by Mosquitoes! This creek yields its treasures very reluctantly. I looked at hundreds of rocks and brought back only six. One is an 'X' shaped burrow. Another has a bunch of wavy ridges through several layers which I presume are either geological or maybe fossil algae that is new to me. Also got a few 'bumpy' bryozoans, which I have taken to calling 'Parvohallopora' until I can figure out what they really are in Georgian Bay formation. Much of the area was packed with trace fossils...intensely detailed, but boring and with no sign of shells or any fossil life forms. The layer can be observed in place, extending for hundreds of meters, with nothing but burrows and little globs. At one point I found, to my surprise, that the broken shale pieces were pressed against a Queenston formation layer with their detailed surface against the flaky shale. That was surprising and unintuitive to me. I visited my traditional tiny outcrops, one with lampshells and the other with large branching bryozoans (flip side of a layer with large wave ripples). Fossil buddies were: toad, frog, cardinal, and 2 woodpeckers.
  3. Bryozoan i.d. help please

    Could someone identify if these are bryozoans attached to this bivalve from the Faringdon sponge gravels UK please. Scale bar millimetres.
  4. Brachiopod ID, + Bryozoan?

    Hello all. I'm an amateur fossil hunter, so this might not seem that exciting, but I was really happy to find these four rocks with what I assume are brachiopods in them. These were found on a small, rocky beach in western Michigan (so rocky that most people would probably prefer not to swim). The specimens vary in size quite a bit, with the largest one being about 2 cm (this one is also one of the most well-preserved). In one of the rocks I see some lacy-looking material which I believe is probably a bryozoan frond, but I'm not too sure, so if anyone could confirm that too, I'd appreciate it. In the last few pictures, I wet a couple of the specimens themselves to hopefully make them easier to see. I hope these pics are good enough. If anyone could give me info on what exactly these little guys are, it would be greatly appreciated. Thanks!
  5. hash plate plus

    2 inch by 1/2 inch with Crinoids, Bryozoans, more and did not expect to see the 3/8th inch 0.9 cm pyrite on it. Allegan County, Michigan From my dig site Yesterday. I believe it is limestone. Would like the approximate age for the fossils and about when did the pyrite form on it?
  6. Dear Guys, During the last several years i detected unknown truth talking about Lithuanian boulders- the Carboniferous and Permian marine rocks are very numerous and their age is various- there can be found almost each stage of Carboniferous and Permian. The main rock types are three- dolomite and limestone with masses of brachiopods that is various in color, stromatolite limestone with mollusks and unidentified cephalon like fossils, and the last- lacustrine limestone with coelacanth scales and possible plant remains (Carboniferous rhabdodermatids are very numerous). Carboniferous period and Early- Middle Permian was not known in Lithuanian glacial boulders so I very need the strong expert, especially who works on Carboniferous- Permian brachiopods. If my age determinations are correct then I will write the scientific book about this discovery and i think there is huge possibility that many of these boulders could be transported by someone glaciation from Northwestern Russia (or Northern Ural) because there are big areas of Devonian, Carboniferous, Permian and Triassic rocks near surface and Northern mountains potentially could be the cold center at some glaciation period in the Pleistocene. I will show all the pictures with fossil identifications and size, maybe someone will tell the opinion about the taxon and age possibilities. Any contact detail or other important information is very welcome! First image- Angiospirifer (Late Carboniferous), 1.1 cm length Second image- Anthracospirifer (Middle- Late Carboniferous), 1.8 cm length third image- Archaeocidaridae sea urchin plates (Carboniferous), 5- 8 mm diameter Fourth image- unidentified brachiopod species from Carboniferous- Early Permian (8 mm- 1 cm length) Fifth image- Atomodesma? bivalves from Kungurian boulder with Waagenoconcha brachiopod (1.7- 2.3 cm length)

  8. Shell type?

    Hi all, this fossil hash plate is like a super hard gray mud with cracks. Even using a wood rasp to smooth much off. Mostly a trial or training piece. The shell was broken and in layers, with much covered. I have removed a lot of the cover, can I get an I'd, and is it worth continuing? I also see two Brachiapods, and they still some material stuck on the surface. I do not know of a way to dissolve the matrix, to recover the fossils. ultrasonic does nothing.
  9. Michigan Brownstone

    I Found this last week on what I believe some call Lake Michigan Brownstone ? 3 5/8th in x 4 inch. Has Bryozoans and one I believe is a brachiopod 15 mm wide attached to the side. Bob
  10. Lots of ordinary things lately at Etobicoke Creek and Joshua Creek. Of course, when I began hunting in April 2019, I couldn't imagine finding such treasures, but there you have it. At the former location, we seem to have fun finding "How many decent-size orthocone nautiloids can fit on one rock," and the number appears to be 10 or 12 in some cases ! We also seem to be able to find snakes when we lift rocks, which can be disconcerting. Recently I noticed some unpromising "wavy surface" rocks, but they had a layer underneath with branching bryozoan fragments. Turns out, there are lots of them, and some are the largest chunks I've ever seen. So today I was out in the rain, getting muddy. I had to leave lots of great rocks...they were reasonably heavy chunks. Tree roots along the creek had split up the shales, pushed some promising rocks through to the forest floor, and dumped lots of slabs onto the creekbank. When I get some of these rocks cleaned up, I hope to post some pictures. Meanwhile, here is a group of recent finds.
  11. Bryozoan blobs

    Lately I've encountered quite a few blobs, and I'm not sure what types I have, or if some of them may be just weathered rocks. I get the impression that twisted blobs with smooth surfaces are Stigmatella Vulgaris, pictured in lower right of a 1921 Dept of Mines publication. I'll soon gain a sense of how to tell one from the other.
  12. With fall just around the corner, I was able to get in a hunting trip with my friend Jeffrey P, to the wilds of upstate NY: Specifically, the Deep Springs Road Site, in Earlville. I met up with Jeff at our usual meet up place, and time, (6:00 am at a park and ride near Jeff - about an hour away from my home.) and loaded his gear into my vehicle. Off we went. We enjoyed some very nice scenery, once the morning fog lifted. Hills, streams, farms, and wildlife. We both saw a bald eagle flying by, and some turkeys, chickens, and a deer or two. After a stop for gas and some food in Roscoe, NY, we headed up to Earlville. It was, as usual, a good ride, punctuated with some great conversation, and some interesting music. We arrived at the site around 9:50 AM. The place looked like it had be worked quite a bit, with large areas of rubble from other people's digging. The weather cooperated nicely, - it was beautiful, with temps in the low 70's, and we enjoyed sun and some cool breezes. We got to work quickly, and finds came in drips and drabs. We both made some decent finds, (pics to follow.) Jeff getting ready to start the day. We hunted until about 5 pm. With a 4.5 hour drive ahead, (for me) we got on the road. A brief stop at everyone's favorite Scottish Restaurant, and a quick stop for gas, we finished the day out with more good conversation and music. Traffic was great until after I dropped Jeff off. I spent about 25 minutes in stop and go traffic on I-84 through Southbury. I got home at around 9:45 PM. Jeff is such a great guy to hunt with. Informative, supportive, knowledgeable, and often quite funny. I always enjoy hunting trips with him. Thanks again for another great trip, Jeff. Please feel free to add your finds here, Jeff. Hope you enjoyed the report and finds. Until next time, Kind regards,
  13. Not a huge piece of my collection but still neat. The fine details of these marine animals are often lost to the ages but every once in awhile you find a few pieces that catch your eye. I was digging through my collections curious about those fossils I found when I first started collecting. Came across this little invertebrate nugget. It is worn but the color and how it hugged the matrix was attractive. Taxonomy: Animalia; Bryozoa; Ectoprocta; Gymnolaemata; Trepostomata; Amalgamata; Monticuliporidae

  17. 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.
  18. 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,
  19. 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.

  22. 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 ??)
  23. 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:
  24. 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!
