Hoooooooooooorrrrrrrrrrrraaaaaaayyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here we are at last, into Adam's Silurian. Thanks for looking. First up is the Lower Silurian or Llandovery and I begin with a problem. I posted this one incorrectly in Adam's Ordovician as it had got it's label muddled up with an Ordovician Favosites I had that has vanished in the move here, but is being replaced by kind forum member @Herb Anyway, this, I remember now I've found the correct label, is from the greenish Browgill Formation, part of the Stockdale Group from a cutting near Skelgill (Skelghyll) in Cumbria, Northern England. It seems to be a tabulate coral, but I can't find any listed for this location, only mentions of small, rare, rugose corals. It has the star shaped corallites of a Heliolitidid, but seems to be tightly packed together like a Favositidid. A couple of species of Palaeofavosites seem to be close and are a bit star-shaped,, but anyone know any better? @TqB@piranha hmm who else? The coral bit, an external mold, is a maximum of 3.5 cm across and each corallite up to 2 mm.

Hello everyone! Recently, I found a gastropod imprint with a weird zig-zag pattern in the Cretaceous Merchantville formation (hard pan) of New Jersey. After showing it to a few folks, it was suggested that it may maintain its original color pattern. We aren't aware of this occurring on the Atlantic Coastal plane so I wanted to get more opinions on it and if it could be that. Thanks for your time! Frank

The Paleontological Society of Austin gets to go to the Lake Jacksboro site once a year.. Dallas Society also goes out there, so we try to make sure not to overlap, but surprisingly, the site is so productive, there's always great stuff to find! The Carboniferous Period- Pennsylvanian site is well known for its wide variety of fauna. I've been out there a dozen times and almost every time I find something new! It may seem a bit desolate, but it's worth the trek! My first happy find was a crinoid calyx. As with most Pennsylvanian sites, crinoids are prolific. But I've not found much complete crinoid material...but this time, I found two! Another fossil that is a special find out there is a little thing called a Rostroconch. It was originally thought to be a bivalve, but has been given it's own class. This is only the third one I've found. They are not common. Another of the most sought after fossils there are the Goniatites and Nautiloids. The big ones are rarely found whole, but you can also find tiny ones in the micro zone. Gonioloboceras and Tainoceras are the most common largeish ones and I have yet to find a GOOD complete one of either. I have found a few Gonioloboceras what were either almost whole or were so weathered that they look like zombies! This time I THOUGHT I had finally found a good complete one! This is what I saw and my heart did a flip flop! Unfortunately when I cleaned it up, the center was eroded but I actually kind of like the other side, even though it is weathered and a little "zombified" at least it's mostly whole! But the zigzag sutures are amazing! I found a few smaller ones in the field, but the big payday was the two 5 gallon buckets of micro matrix I brought home with me from the micro zone and found a PLETHORA of tiny goniatites this time! Top Row- R: Glaphyrites millsi C: Imitoceras grahamensis L: Neodimorphoceras texanum Bottom Row: Prouddenites grafordensis C: Wiedeyoceras pingue L: Unknown But this is kind of fascinating - it was encased in a little bit of matrix, so I tried to break it off but ended up kind of breaking the whole thing. But because of that, it released the tiny interior! Peritrochia sp. I certainly wish it were whole, but it's still fascinating to see the interior. Another new find was this little Brachiopod Fimbrinia - I'd been looking for one of these for a while and finally found one! Another nice little Brach with a surprising pearlescent surface - Kozlowskia splendens Also found this little Orbiculoidea missouriensis Here is an unusual coral called Palaeacis perpendicularis Found lots of cool gastropods, but my all time favorite is Cymatospira montfortianus I am already excited about getting back out there, maybe in the Fall because Texas summertime is NOT when you want to be out on those flats!

Malibu Creek Canyon Narrows - Oyster Bed and Shell Fossils - Southern California
ezeemonee posted a topic in Member Collections
Some examples of fossils found in the cliffs and boulders of Malibu Creek Canyon Narrows. Oyster Bed and Moon Snail and Turritella Shell Fossils. The species guess for the Oysters based on research is Ostrea (Pycnodonte) Howelli, but I am not sure. Probably Eocene period fossils. Maybe Miocene. Nice area of Malibu creek in the Santa Monica Mountains but difficult to access.-

Pleistocene Shells - Rincon Point, Southern California
ezeemonee posted a topic in Member Collections
Many earlier Pleistocene period shells (~1M yrs ago) from a site inland from Rincon Point in Southern California. Got some great ID suggestions from various people on these and was informed that the shattered Trochita (Limpet like slipper shell) is probably one of two undescribed extinct species known from that deposit. Useful ID references for the area: Phill Liff Gieff, Frank Pesca Jr, Thomas Everest, and others https://inyo4.coffeecup.com/santabarbara/santabarbara.html Cyclocardia / Coanicardita - Grant & Gale (1931) Antiplanes - Raymond, 1904 Cantharus fortis (P.

Hi all. I haven’t posted on here for a while. But thought I’d share this beautiful Mauithoe insignis gastropod I found and prepped recently in New Zealand. It’s about mid Miocene age (12 million). There are only 2 sites in New Zealand where you can find this species. You usually find Mauithoe specimens around 4 cm in length, 7.5 cm is listed as the largest in the Bible on NZ fossil molluscs. Well this beast is bigger than that. As found After prep:

Last weekend I had the opportunity to spend a few hours collecting in a quarry in northern Illinois that exposes most of the Galena Group (Late Ordovician). There was lots of fresh rock to hunt through, and it was a good and productive trip. As usual, lots of gastropod molds were found. Hormotoma sp. Liospira sp. Sinuites sp. Lophospira sp. Subulites sp. Unknown gastropod. Looks like Liospira but appears to curl in the opposite direction. Brachiopods show up too. Most common are molds of what I believe are Rafinesquina (@Tidgy's Dad?). The inarticulate Pseudolingula iowensis is somewhat common. Specimens are almost always crushed and missing shell, but they usually have some shell preservation which contrasts nicely with the yellow matrix. Occasional bivalve molds are found. This one has calcite? crystals. Trilobite parts are uncommon, and the only species I've seen from this quarry is Thaleops, possibly Thaleops laurentiana. Here is a cephalon I found. Now for my favorite finds of the day. A partial specimen of the small receptaculitid Ischadites iowensis. Fisherites is very common at this site, but I had not come across Ischadites before. A partial conulariid. Judging by the visible cross section, the back side is present, so this should hopefully prep out nicely. And finally, what might end up being a complete trilobite. Not sure if there is any more buried, but it does look like at least some of the shell is preserved, so fingers crossed!

I'm a mineral collector rather than a fossil collector, but this gastropod replaced by chalcedony has one foot in each camp. It was labeled (by a mineral dealer) "Turritela fossil snail" with a locality given only as Morocco. It'd like to come a little closer taxonomically if I can. Any ideas? Thanks in advance. Edit: Forgot to include its dimensions: 24 mm tall x 15 mm diameter

I am fortunate enough to have such a huge amount of Middle Devonian Givetian material that I thought it best to put the older Middle Devonian stage, the Eifelian, in its own thread. There are some spectacular fossils here as well though! I thought a good place to start would be in the Formosa Reef, which I believe is quite early Eifelian. This tabulate coral and stromatoporoid reef continues similar complexes found from the Middle Silurian, see my: https://www.thefossilforum.com/topic/84678-adams-silurian/page/3/ thread from page three onwards for details. All these Formosa Reef specimens come from a delightful gift from my good friend @Monica who is a tad busy with life at the moment but is fine and still thinking of the forum. This outcrop can be found on Route 12 near Formosa/Amherstburg, Bruce County, Ontario, Canada. This beautiful-looking specimen came to me with only a third of it revealed but I managed to get it this far after nine days of painful pin prepping. Monica found another one and posted it for ID here: https://www.thefossilforum.com/topic/105528-weird-circular-imprints-formosa-reef-lower-devonian/#comment-1172285 The specimen was identified by another Canny Canadian @Kane to be the little stromatoporoid sponge Syringostroma cylindricum. Hardly a reef-builder, but gorgeous nonetheless. It does have a little thickness to it, but not much. Beautiful! Pretty thin, actually. I love this Monica, thank you!
