    Adam's Early / Lower Devonian

    The Devonian period is known as "The Age of Fish", but could also be known as "The Age of Brachiopods." In the Early / Lower Devonian, brachiopods reached the height of their diversity towards its end in the Emsian. We see the ancestral groups occurring, lingulids, craniids, orthids, protorthids, pentamerids, rhynchonellids and strophomenids, as well as the later successful groups we have seen before such as atrypids, athyrids and orthotetids, plus the rise of spiriferids, spiriferinids and productids and the beginning of the terebratulids. By the end of the Devonian , several of these g

  8. I thought I would share this recent fossil purchase. I was fortunate to obtain this fossil from the lower Devonian in the southwestern region (Podolia) of Ukraine. Two ventral snout regions of type of heterostracan (jawless) fish called rhinopteraspid are exposed. The bone detail is simply remarkable. There is “tiling” of the underside of the long (rhino) snouts with dentine and/or aspidine (acellular enamel-like substance) in parallel lines arrays with a more uniform bone matrix underneath. The pre-oral-plate is angled in toward the mouth and displays many external textures of bone that presu

  11. On Tuesday this week, myself and some of my family spontaneously decided to get out and drive to some interesting places in New York state to enjoy the day. We visited some beautiful locations like these two waterfalls: On our journey, we ended up around Gilboa, which is the location where one of the earliest known fossil forests was discovered with amazing plant and animal life, some of these fossils are exhibited outside near the town hall. This, being one of the many locations I had wanted to visit for years, was an opportunity I could not pass up, so while driving th

    Lower Devonian plant

    L.S., Hope someone on TFF can help me with the identification of a plant fragment from the Lower Devonian (Pragian) of the Belgian Ardennes. The specimen in question consists of a 17 mm-long, 12 mm-wide oval-shaped body, which is seemingly covered in equant scales (though this could also be an artefact of the surface preservation) and has curved spine-like protrusions (see right hand-side of specimen in first two photographs). The detailed structure of the specimen is quite difficult to capture, so I added four photographs taken under different lighting conditions. Hope this is eno

    plant material

    I found this plant material in Union Springs, NY...at the conjuntion of Lower Devonian/Upper Silurian. Along with this was found...ugh, can't remember the name. Remind me of bean sprouts...I think starts with a "C". Is there enough to identify? Thanks Greg

  15. Was visiting a quarry in NW Ohio two weeks ago, and came across this gastropod. It's about 2" X 1.5" Had to do some research to identify it. Saw that not too many Platyceras dumosums have been discussed/presented on TFF. It's completely pyritized. Inside and out Here's a drawing of how they're thought to have looked Another view It also has some non-pyritized bryozoans (I think?) attached to the coil. How does this occur?

  18. Hello all! I’ve been going through some of my fossils from the New Scotland Formation and I stumbled upon this intriguing little piece. It’s about a centimeter wide and seems to be separated in the middle, almost like two connected plates of some kind. I’ve got a decent collection from this formation and I’ve never seen anything like this. Hopefully somebody on here can help me out. Thanks for looking!!
  19. Hello everyone! I have recently purchased this skull roof from an actinolepid placoderm from the lower Devonian of Ukraine, The fossil was labelled as Kujdanowiaspis, but there is also a closely related genus found there called Erikaspis. I have been looking at several papers to try and see what distinguishes the two and if it is possible to tell what mine is but right now I am not sure. Any help identifying the genus and even species if possible would be great, Thank you
  20. Hi all! After reading about @Kane's autumn trip to Ontario's Formosa Reef (Amherstburg Formation, Lower Devonian), I was inspired to find it and check it out myself. With the help of Ludvigsen's 1986 paper entitled "Reef trilobites from the Formosa Limestone (Lower Devonian) of southern Ontario," along with Google Maps' Satellite View, I was able to locate the reef, so Viola and I made the 2-hour drive yesterday to search the site for some new fossils. Here's Viola standing atop the reef: This was my first find of the day - a rock with a brachiopod AN
  21. Hi all! Yesterday I visited Formosa Reef here in Ontario (Amherstburg Formation, Lower Devonian), and I found these weird circular imprints on a few rocks - does anyone know what they are? @Kane Thanks a bunch! Monica photo with ruler for scale: close up photos:
  22. Hello everyone! I wanted to share some good news with you all... On Monday, March 16, 2020, I visited "Formosa Reef" in Ontario (Amherstburg Formation, Lower Devonian) for a little fossil hunt. One of the rocks that I found at the site had a trilobite piece that @piranha identified as the hypostome belonging to the trilobite Acanthopyge contusa. When I asked him if he knew of any museum/researcher who might be interested in my specimen, he suggested that I contact the Royal Ontario Museum (ROM), and so I did. First, I emailed David Rudkin, and this is what

    I've found this Brachiopod but having a difficult time trying to identify it. It looks like "Anastrophia verneuili". However, I found it above the Lower Devonian which it is supposed to come from.

  25. I know this trip happened a while ago, but I’ve been pretty busy as of late finishing up the school year and such and haven’t had a chance to make a trip report. Hopefully y’all find this interesting.
