  1. rapp Creek hunting

    Returned from Singapore (where I gave a young teacher my collected teeth for the last few years). The area where I had been hunting had been covered by a sand-fall. I worked a bit trying to uncover, hoping for some interesting treasures but only came away with the "usual" and the small teeth were more broken and more slanted to triangular bull/ dusky triangular than the more common sand tiger 'spikes'. Some round drum bones, imperfect ecphora, skate teeth and small turtle(?) pieces. Nothing exciting, but good to be out again.
  2. Horn coral or calamite?

    I found these two fossils at my camp in munising, Michigan thinking that they were horn coral fossils. But now I am having doubts and am thinking they might be calamite fossils (or some sort of plant fossil).
  3. if anyone can help share some info on the following.this is a cretaceous stream but I'm assuming maybe glacier brought in the coral and any info on it and age and any info on the others...thanks
  4. Coral ID Confirmation

    Hello! This coral is from Aurora, NC area. I THINK it is Solenastrea hyades - Is that correct? My sister sends these, bless her.
  5. Hungry Hollow fossils!

    Hello all! It's a dreary day, so I'm trying to organize some of my fossils into my new display cabinets, and I was hoping to get some help with identifications. All of the fossils below were found in the south pit of Hungry Hollow near Arkona, Ontario. The age is mid-Devonian. Thanks in advance for all of your help! Monica Photo #1: Definitely a coral, but which one? A type of Favosites, perhaps? Photo #2: Another coral - perhaps Alveolites goldfussi? Photo #3: Still another coral - perhaps Platyaxum frondosum? Photo #4: I have no idea what this brown thing is - help! Photo #5: A trilobite pygidium - can anyone tell which trilo? Photo #6: A brachiopod - no idea which one... Photo #7: Three brachiopods - again, I don't know their identity/ies Photo #8: Two brachiopods - I used to think they were both Devonochonetes scitulus, but up close they appear to look a little different to me - what do you think? Photo #9: The back of the rock from Photo #8 - any idea what those black fragments are?! Photo #10: A pyritized bivalve (thanks, Adam @Tidgy's Dad!) - again, I'm at a loss as to what its identity is Photos #11 and #12: A Mucrospirifer brachiopod, but I'm wondering - is that the lophophore that I see inside of it, or is it just the valve that's been crushed inwards?
  6. Is this coral fossilized?

    They grayish color makes me think it could be fossilized?
  7. Coral fossil or just a skeleton?

    Does anyone jnow if this is a coral fossil or just a coral skeleton?
  8. Fossil ID

    Yesterday, I visited the famous Moenkopi Dinosaur Tracks site. The lady to guided me pointed out shiny rocks, which she said were jasper fossil corals. She let me collect them while I was being guided. I'm sure the pieces are jasper, but I'm not sure of they're pieces of coral. Are they? In addition, there were some other things she pointed out, such as dinosaur eggs, skulls, coprolites, and vertebrae. I already knew these were suggestively shaped pieces of sandstone. I'm sure this misinformation wasn't on purpose, though.
  9. Rugose Corals

    I should preface this post by saying that the Paleozoic, marine ecosystems, and invertebrates are not generally my primary expertise, so I apologize if I am wildly off base or asking stupid questions. Sadly, I did not find these specimens myself, and so I do not have any particularly useful information on age or location. They were left in a desk drawer along with a collection of other invertebrate fossils, most (if not all) of which are Paleozoic in age. I have several different rugose coral species, and I would love to know if anyone can refine that identification further. I thought the colonial rugose coral might be an Eridophyllum species, but I would not bet much on my identification. The third is truthfully in terrible condition and I doubt there is much to say about it, but I thought I would see. Here are the pictures. Thank you in advance for your time and input. Specimen #1: Specimen #2: Specimen #3:
  10. Favosites?

    I should preface this post by saying that the Paleozoic, marine ecosystems, and invertebrates are not generally my primary expertise, so I apologize if I am wildly off base or asking stupid questions. Sadly, I did not find these specimens myself, and so I do not have any particularly useful information on age or location. They were left in a desk drawer along with a collection of other invertebrate fossils, most (if not all) of which are Paleozoic in age. They look to my untrained eye like Honeycomb Coral (Favosites sp.). Here are the pictures. Thank you in advance for your time and input. Specimen #1: Specimen #2:
  11. I've posted this same coral some time ago, along with a bunch of other finds from the same locality, but it's identity is still bugging me. In my search, I've narrowed the potential genus down to either Cladocora or the montlivaltid Thecosmilia. The locality is the Čerevićki potok fm., Serbia, Maastrichtean. In the Paleobiology Database, only Thecosmilia has been reported in the locality, but Cladocora was also apparently reported in the relative geographic vicinity. View of the entire colony: View of the entire colony(up close): View of the corallites: Album link: https://imgur.com/a/vtWMX Here's the descriptions of both genera, from Corallosphere: Cladocora Thecosmilia So, what's your judgment? Any help would be greatly appreciated.
  12. Forams bound to oysters?

    Hey all, I am working on a project within the Glen Rose Formation of Spring Branch, Texas. Could somebody take a look at these giant forams (Orbitolina texana) and see what the binding organism is. I originally thought they were oysters but now my professor suggests that they make be barnacles instead... These forams are roughly half a centimeter in diameter
  13. Location: SE Portage County, Central Wisconsin, USA. Geology: South Western advance of Green Bay Glacial Lobe. Former Glacial Lake Oshkosh. Niagara Escarpment Debris. My land. Ordovician onward. Trying to learn, but am confused. I tentatively identified the below specimen as a Honeycomb coral, based on info from the below and input from local “experts”. None are Paleontologists, but one is a Natural History Museum Director. Begin quote: Favositid tabulates: Honeycomb corals The favositid corals are quite common. They usually formed large colonies. The corallite is prismatic in shape, resembling honeycombs. Favositids have mural pores, tiny holes in the wall of the skeleton, which connect different corallites. These pores are distributed in characteristic patterns and numbers, which are useful for distinguishing the various types of favositids. Favositids lived from the Ordovician to the Permian, at which time they became extinct. They are most abundant in middle Silurian to lower Devonian rock. Favosites is the most common fossil coral in Wisconsin. https://wgnhs.uwex.edu/wisconsin-geology/fossils-of-wisconsin/coral-gallery/corals/ Wisconsin Geological and Natural History Survey, UW Extension The confusing part is that some surfaces of this specimen show no pattern or regular form. Just like most of my finds. Are there any clues to indicate a rock of this structure may be a coral? Other than cutting it open? I have about 50 like this, but only two others show the typical pattern. The rest just have the “circles” on all sides. All are basically the same composition of material, but colors vary. All have inclusions of crystals. My vision is limited, so I only know what I have found after I wash it and look under a lighted magnifier with a loop. Photographing helps a lot as well. I just go on shape and colors when picking up. Then use a small hand held magnifying glass to examine. Sometimes wash off with a little water first. My son in law, who has (almost) a geology minor from local University, is amazed at what the glaciers “dumped” on my land. Note that a large part of the classes were related to local fossils, due to the abundance of them. Please let me know if my ID is correct, and any pointers for identifying specimens which do not show the structure, only the “circles” or “cavities”. Thank you. 1 2 3 4 5 6 7
  14. What is this? Is it a flipper?

    Hi there, I'm new to fossil hunting and came across this today in the newly surfaced coast land mass at Kaikoura, New Zealand. It's quite large; at least a foot long. Move read about the fossils of ancient dolphins being found in the area and was wondering if there was any possibility of this being linked to those finds? any help in identifying it would be greatly appreciated!

  16. Favosite, Tabulate, Something Else?

    Favosite, Tabulate, Something Else? Location: SE Portage County, Central Wisconsin, USA. Geology: South Western advance of Green Bay Glacial Lobe. Former Glacial Lake Oshkosh. Niagara Escarpment Debris. My land. Ordovician onward. Size: 7.25 cm by 7.5 cm by 7 cm (edges of “triangle”) by 3 cm thick. Wondering if this is worth some refining, or if the features would be lost? It has a pretty thick coating in places of deposits. All comments welcome on ID and potential for refining. Thank you. coral 4 coral 4a coral 4b coral 4e coral 4c coral 4h coral 4i
  17. Coral and Others

    Second posting attempt. Sorry of there was a delay and this is a double topic Central Wisconsin, USA. Glacial Drift/Green Bay Glacial Lob W. Advance/Glacial Lake Oshkosh Area. Ordovician onward. Unlike anything else I have found. Trying to identify all the various corals/critters that were preserved in this. So, have possibly identified barnacles, the abdomen end of a horseshoe crab, various shells/snails, and several corals. Please let me know if my ID’s are way off. Could this have been a coral colony that was overtaken by 1 or more other colonies? Then, as the corals died, barnacles moved in, along with other marine life? So fascinating. Putting this one in the hands of the experts here. Camera will always focus on the size reference in my photos (cell phone camera), so cannot do that. Size is 10.5 cm long, by 7.5 cm wide by 6 cm thick. Hope this helps. Posted this on another forum and was told it was nothing more than a chunk of chert. Some photos have details of what I think is there. Thank you so much. 1 2 3 4 5 6 6 9 11 10 12 13 gray coral 18 gray coral 17 gray coral 16 gray coral 15 close 1 words gray coral 15 gray coral 14 close 1 words gray coral 14 A snail shell? snail Posterior end of Horseshoe Crab?

  18. Excited Newbie Coral ID Requested

    Rudist Coral? Location: SE Portage County, Central Wisconsin, USA. Geology: South Western advance of Green Bay Glacial Lobe. Former Glacial Lake Oshkosh. Niagara Escarpment Debris. My land. Ordovician onward. Been lurking here for a couple of years, learning everything I can. Finally decided to join. Always loved fossils, but never had access to many. That changed a couple of years ago, when I unknowingly purchased some very unique land. The age of fossils I find on my property range from Ordovician era to more “modern” times. Have found Chain Coral, Favosites and Horn Coral previously. Plus a few other marine, plant, bone and tooth specimens. There are many moraines in the area, some smaller ones are on the land I have. I posted the below specimen on another forum but was told it was “just a hunk if quartz”. Hoping all the experts here can shed some light on this. The overall feel is waxy, not like quartz around here. There are some inclusions of quartz crystals. If it is “just a hunk of quartz”, then it is an interesting quartz rock. Apologize for not being able to put a size reference in the photo, as my phone kept focusing on the size reference. The specimen is 2”, 50 mm across by 1 ¾”, 45 mm on the top. The sides are 1 5/8” 40 mm by 1 2/3” 70 mm. The formation on the top which reminds me of Rudist Coral is 3/8” 9mm, across. The colors in most photos are true. I did change them a little in some photos of the top to enhance the formations. Sorry, they are a little blurry. Taken with my phone, a portable photo tent and combo of LED and natural, North facing light. During the glitch over the past few days, I composed several posts for ID. Please let me know how many I an post right away, or if it is better to wait a few days between posts. Top: Top a top b Top c Top d Side 1: side 1a side 1b Side 2: side 2 Side 3: side 3a side 3b Side 4: side 4 side 4a[/url Bottom: bottom a bottom b bottom c Please let me know if additional photos are needed. I tried to take some of each surface, but it was tough. I can crop the other photos I have to show more detail in specific areas. Thank you.
  19. Devonian coral from Resteigne

    Hi all, During my trip to Resteigne, I namely found this coral. Here is the location info: Resteigne quarry, Belgium Jemelle Formation (mostly) Eifelian, middle Devonian; ~ 390 mya Any possibility to name the species do you think? Thanks in advance for your replies! Max
  20. Devonian Coral? From Resteigne

    Hi all, On my trip to Resteigne last weekend, I namely found this thing. At first I thought it was some kind of coral, but others are having their doubts. So now me too! Here is the location info: Resteigne quarry, Belgium Jemelle Formation (mostly) Eifelian, middle Devonian; ~ 390 mya I started prepping it a little bit, and noticed that this matrix was a little bit softer than the other matrix... So maybe this is from another formation. If I remember correctly, this was one of the few finds from the second level (the levels of the quarry are ground, 1st, 2nd and 3rd level. So maybe the different levels indicate a different formation), opposed to the majority of other finds which were from the first level (and have a much harder matrix). So. What do you think it is? Looking forward to your answers! Max
  21. Specimens of corals from the Devonian limestones of Devonshire in England are hard to come by nowadays - this is one I've just bought and repolished. It's likely to be a 19th century sample from when the quarries and marble trade were flourishing - many such pieces were sold then as scientific specimens, and many more were used decoratively. Frechastraea sp. , Givetian/lower Frasnian, Torquay area. The brass scale bar is 1cm long.
  22. In the Devonian quarry

    Hi everyone! So Friday morning, after a few enjoyable days of skiing in Switzerland with my dad, we decided to leave the village because the weather was really becoming horrible for any further skiing (especially for a beginner like me!). I had done a little bit of research as to what fossil locations we could visit on the way back home, and eventually Kevin @Manticocerasman very kindly pointed me towards the site of Resteigne in Belgium! A (no-longer in use) quarry known for its Devonian brachiopods, corals, crinoids and sometimes trilobites. Which was a fantastic opportunity for me, because in my so far 7 years of fossil hunting I had never been in a quarry or hunted for trilobites!!! So seizing the opportunity, we booked a Bed & Breakfast in the small village of Resteigne. We arrived late that evening after a long and annoying road, but luckily the hosts were still up and warmly welcomed us. The man knew quite some things about the great geology of the area, and told us that apparently this region was now a Geopark of the UNESCO! (To avoid any confusion, we are allowed to collect fossils here without any problems. It is not like the national parks where it is forbidden to take things out). He sometimes found some fossils himself when he was going out on walks. After a good night sleep and a delicious breakfast, we set out to the quarry.
  23. coral fragment or

    Ok location, near old limestone quarry in moni area. it is actually just a 10% of the actual visible coral there.. i think too much water or/and sun made it fragile, and my bag was full, and I was too tired to sit there and do what I had too. But here it is. Same depth, matrix and just a couple of meters away from the Strombus coronatus gastropod fossil. I included some 'thingies that could belong to the coral, or be something else. and the "thingies", I have another 1-2 of those.
  24. Bryozoa?

    Any ideas on this guys? I guess it's some type of bryozoa/bryozoan (dunno if it's one beast or lots of 'em) It's like an undulating mat. The 'mat' varies in thickness from, I guess, 2mm -5mm. The round things are in relief not indented. Era: Silurian Location: Wrens Nest, Dudley, UK @TqB
  25. Unknown imprint

    You guys sick of my threads yet? Sorry, there’s a lot more to come. Here is an interesting surface which features may be purely natural erosion or a fossil imprint. Coral maybe? Almost looks like fossil rain drops, eh? Any clue if it’s organic in origin? From northern Illinois.
