A few more Riker mount displays with macro specimens from the Miocene of Virginia
MarcoSr posted a topic in Member Collections
Below are some more of my macro fossils that I’ve recently put in 16”X12” Riker mount displays. All of the specimens in these displays come from the Miocene of Virginia. The first display with shark/ray specimens, the second display with bony fish specimens, the third display with marine mammal specimens and the last display with reptile specimens. I'm getting some more Riker mount displays Saturday and I'll post some more displays with more of my macro specimens from the Miocene of Virginia. To see a previous post with Riker mount displays with macro specimens from the Paleocene Aquia Formation of Maryland and the Eocene Nanjemoy Formation of Virginia check out the below link: http://www.thefossilforum.com/index.php?/topic/101415-a-few-riker-mounts-with-specimens-from-the-aquia-formation-of-maryland-and-the-nanjemoy-formation-of-virginia/ To see a previous post with Riker mount displays with macro specimens from the Miocene Round Mountain Silt Formation of California, the Eocene/Oligocene Chadron/Brule Formations of Nebraska, and the Miocene of Virginia check out the below link: http://www.thefossilforum.com/index.php?/topic/101441-a-few-more-riker-mount-displays-with-macro-specimens-from-the-round-mountain-silt-formation-of-california-the-chadronbrule-formations-of-nebraska-and-the-miocene-of-virginia/ Display with shark/ray specimens. The top of the display has shark vertebrae. Then there are Otodus megalodon teeth (for size reference the largest megalodon is 4.75” and the smallest is .625”). Then there are some Hemipristis serra shark teeth. The bottom has two eagle ray barbs and pieces of eagle ray dental plates. Display with bony fish specimens. The top of the display has bony fish vertebrae with a Wahoo jaw (6.5” long for size reference), a hypural fan, several bill fish bills and two small fish jaws. Then the middle has lots of fish jaws with some black drum jaws on the far left and most of the other jaws to the right being red drum. The bottom has ocean going sun fish bones including three jaws and there are some more bony fish vertebrae on the far right. Displays with marine mammal specimens. The top and middle of the display has Cetacean bulla and periotic ear bones (for size reference the largest is 3“). The bottom left has Cetacean vertebrae, flipper bones and two small jaw fragments. The right contains Cetacean teeth. Display with reptile specimens. The very top has two coprolites most likely crocodile. Then some crocodile jaw pieces with a number of crocodile teeth and a crocodile scute (for size reference 4.5” by 3.25”) on the far right. The bottom has turtle caprice/plastron pieces and a good number of leatherback turtle carapace bones. Marco Sr.- 9 replies

Coral hunting in the Weißenegg-formation, Styria, Austria (Langhian/Badenian, Miocene) – 10/17/2019
FranzBernhard posted a topic in Fossil Hunting Trips
Hello! Finally, I have some time to post this fossil hunting trip from a warm and sunny day in October, 2019. Introduction The Miocene Styrian basin in Austria is mostly filled with various clastic sediments, e.g. fossil-rich “Florianer Schichten” around St. Josef. The “Mittelsteirische Schwelle”, a north-south trending high-zone of palaeozoic, slightly metamorphic rocks, however, is, in a very literal sense, the base of various biogenic carbonate rocks (“Leithakalk”). The individual carbonate bodies are of slightly different age – spanning the whole Badenian (about three Million years) - and composition. The younger ones to the north around Wildon are characterized by coralline algae and often oncoidic limestones, corals are extremely rare there. To the south, corals became locally an important part of the limestones, besides the coralline algae. No really big coral reef structures have developed, though; coral carpets and small coral batch reefs are characteristic. Various maps from the internet and literature of the visited area. 1 = Kittenberg; 2 = Hötzlweg Depositional scheme of the Weißenegg-formation around the “Mittelsteirische Schwelle”. Within the green rectangle the area of interest. Relief map of the area north of Heimschuh. Note the many very small to medium-sized quarries. Some cliffs are also visible. These corals are witness of tropical to subtropical temperatures in this area about 15 Million years ago. Coral development is considered to depend on local factors like sediment input or (non-)exposure to severe wave action during storms. Coral diversity is relatively high, with at least a dozen of genera described or mentioned. About four years ago, I have prospected the area north of Heimschuh several times for corals. My goal was to find some good coral sites. Fossils in the wild are not super-abundant in this formation, but I succeeded to find a few good spots. Corals are by far the most abundant fossil group, bivalves etc. are much rarer. (Note: there is a very large, active quarry for portland cement fabrication in Retznei nearby, that is famous for all kind of marine stuff, incl. Meg teeth and other large vertebrates.) I will present two sites that I have visited again at 10/17/2019, but already also four years ago. One is at Kittenberg in the woods (1), the other one is a small outcrop along a minor road called “Hötzlweg” (2). Continued...- 8 replies

Last Friday, January 10th, is a day I'll remember because of this tooth. It is always a thrill to find one of my favorite fossils, and this one, by size alone, makes it a tooth from a small horse that predates Equus .sp. I find enough of these teeth to consider my self above average knowledge on these late Miocene horses. An early Miocene horse: Parahippus is a horse that evolved in North America about 18 million years ago and one of the best examples of Parahippus in all the United States comes from Thomas Farm, a fossil site that’s about an hour northwest of Gainesville. Unfortunately, I do not find Parahippus teeth. I do find Calippus, Nannippus, Cormohipparion, Hippohiparrion, neohipparion, many of which filled the gap between 13 mya to 3 mya. Look at this Cormohipparion from FLMNH and compare to my newest find above. Having seen 100s of these small teeth, the new find is very different, even though the size (17 by 15 mm is exactly the same as Cormohippaion that I have in my collection.) My new tooth has to be pathological or extremely rare. Here is the new addition after it is completely dry: So what did I do. Sent an email to Dr Richard Hulbert, Director of the Vertebrate Paleontology Research Lab at the University of Florida. What does he think? Not many choices here. This afternoon, I sent this tooth (after taking photos) to UF Vertebrate Paleontology Research Lab so Richard and his team can perform that "detailed analysis" he indicated at the start of his email. @Harry Pristis @fossillarry@PrehistoricFlorida Maybe the tooth will become famous, mentioned in many research papers. Maybe not, either way I love this hobby..... Jack

These pictures are one a fossil a work friend gave to me. He said he dug this up, on the opposite side of where I dig, twenty years ago when the plant first opened (I was 2 to 3). I'm thinking medium sized mammal, somewhere in the cloven hoof family. any ideas?

More overburden mammal fossils, these two are some of the better mammal vertebrae I've found. Any guesses? I've had a hard time trying to pin point it based solely on their shape. Ill post the fish vertebrae next. s, these two are some of the better mammal vertebrae I've found. Ill post the fish vertebrae next.

Hey all, Apologies for my hand in the photos, they're the only pics of the fossils I will be able to take for a while. Here are two fossils found at the Topanga Formation, or The Ampitheater, a roadside sandstone and siltstone bed in Topanga Canyon, Southern California housing middle Miocene fossils. The clam was my best find, but I'm not sure of its exact categorization. It measures about 4 inches long and 2.5 inches wide and thick. (10.16 cm x 6.35 cm x 6.35 cm) I had some thoughts based on this list that it may be Chionopsis temblorensis (Anderson, 1905), or Saxidomus nuttalli (Conrad, 1837). Also found were these segments which I inadvertently snapped apart, but which revealed some kind of crystallization of the interior. It would be really nice to know what kid of process made that, I tried to start the ID process myself and was unable to find a resolution. Your help is much appreciated, o wise ones. (;

Collected #’s 1-3 at Brownies Beach, Maryland: Miocene, Calvert Formation and #4 in Matoaka, slightly younger formation (I believe). After trying to identify them, I think they are: 1: some type of bony fish, 2: Basking shark (I didn’t think it was a vertebrae until I saw this picture)- https://www.calvertmarinemuseum.com/334/Vertebrate-Fossils , 3: shark, 4: I am making a wild guess at a small crocodile. I am probably way off as this is my first shot at identifying these, so I thank you in advance for your insight.

Hello, I found this today at Brownies Beach. It’s in Maryland: Miocene, Calvert Formation. My best guess is that it is a dolphin rib bone. I am assuming it’s marine. What do you think? Thank you,

Scientists use ancient marine fossils to unravel longstanding climate puzzle by Cardiff University https://phys.org/news/2020-01-scientists-ancient-marine-fossils-unravel.html Ancient marine fossils reveal how rising sea levels trapped carbon in the oceans preventing extinction-level global warming 14 million years ago. Fossil records suggest high levels of carbon was captured in ocean sediment. Significant volcanic activity had previously led to extinction level events.

A trip to the beach, didn't yield much, some badly worn teeth (no shrimp coprolites!) The water is super clear, should be good after the next good north blow. Deer season is over so tried the creek in the woods, unfortunately the water was up (and cold) and leaves everywhere. Found a new spot and worked it for a couple of hours with nothing spectacular. Less sand tiger spikes there? Found a puffer plate (had not seen any in a year or so), the pretty red mako (more red-bronze than the scanner shows; no root but may go to someone for jewelry), and several small and colorful teeth. No angel shark teeth, no cowshark teeth, and only a few drum teeth. Always amazes me how different the yield is, reproducibly in some older spots, not sure of the new. Slightly different depth or time originally? Or maybe mixing after washing out and re-sedimenting in holes?

Most times when hunting, I find fossils that I know, and very few unknowns. In rare instances, I am finding multiple fossils that I do not recognize immediately. I usually pay far more attention to the far more stunning fossils, and ignore those I "think" I know or those that are just "odd". I mis_identified this 1st entry as a juvenile tapir tooth. Here is an opportunity to ID this fossil before @Harry Pristis sees this post. Harry has a gallery photo that highlights this 14-15 mm Florida Fossil. I wanted to point out how easy it is, even for the experienced fossil hunter to get it wrong. On the same day, I picked up this fossil, almost tossed it, and then thought "unusual texture", and toss it into the collection bag. I do not know what it is... but now I am thinking claw. There seems to be a slight "connecting "ring" on photos 1 and 2, and some wear on the tip in photo #3. Originally thought some type of deer tine. As always, suggestions & comments greatly appreciated. Jack

Last Thursday, I was hunting the Peace River watershed with a friend. When we returned to his home (close to the Peace River), he pulled out 2 small teeth. One he had found during out hunt that day and the other a couple of months back. He asked me to identify them and leverage the TFF community if possible. To me , this was obvious. While I can not explain the size and I have no idea what the species is, horizontal "banding" on a canine shaped tooth means one ID and one ID only: Whale. I underline that statement because I want to be challenged if my assumption is incorrect. In the experience of TFF members, have they ever found a tooth, other than whale, that shows this telltale banding? Here is a marine mammal tooth I found 8 years ago in Horse Creek, a tributary of the Peace River. Horizontal banding and an enamel tip!! I know better than to ask for an ID below the level of "whale" on these teeth. As far as I can tell , no one has done a scientific study in the state of Florida on fossil whale material. I was fortunate, almost exactly a year ago to host a TFF member and fossil hunter to a couple of Florida fossil hunting trips. @JBMugu found some really nice Florida fossils but he gifted me something I valued much more. STH Whale teeth See the telltale banding close to the root? Maybe these small Peace River whale teeth are in the same family as Aulophyster. Maybe not... I would love to have Bobby comment on this, but I think he is busy with his day job. Next best thing is an old Bobby comment on the same topic of Small whale teeth. http://www.thefossilforum.com/index.php?/topic/95733-sharktooth-hill-teeth/ What I read from this is that Bobby thinks "small kogiid sperm whale" is an option!!!! Harry has a great picture_photo of Kogiopsis .sp Whale teeth, and I myself have found many at the 3-5 inch size. So, what is this thread about beyond small Florida whale teeth that can not be identified by anyone? There are numerous TFF members who hunt in Florida, hunt on the east coast of the US, find whale teeth while hunting worldwide. Please attach photos of any whale teeth under the length of 50 mm and around a diameter of 10 mm. I am trolling for whale teeth that look like these, and the names of whales like Aulophyster who had small teeth. Thanks for any contributions , Jack

Hi everyone! I recently went to the Matoaka Cottages in southern MD where I found a mysterious looking object, the Choptank formation is exposed here and from what I can tell it is bone of some sort, as it still seems to have bone marrow inside of it. My second guess of the object was some sort of tooth, I had my bets on a peccary canine but my main guess is still bone. If someone could help me identify this it would be a huge help!

Hi All, I was given this fish as a present for Xmas. It is labelled as: Syngatus sp, Miocene, Nevada USA The matrix seems very soft and fragile. How would I stabilise it and give it more strength. Thanks

hello everyone, a few days ago surfing the internet I came across a site of fossils from asia. scrolling through the various offers I noticed this skull, the description reported only that it belonged to an unspecified myocene carnivore. All in all the price was quite low for what seems to be the quality of the piece. To a more careful investigation it would seem a hyaenidae even if the present matrix makes identification quite difficult, however still there is something that does not convince me. the matrix seems intentionally put to cover part of the skull. What do you think about it? Even if the price is cheap it's still to high for my poor pockets, so noway I would ever buy it. However it intrigued me alot.

Oh yeah, thats right - its summer here! Tinbum, @mamlambo @6ix @Doctor Mud and the Little Girl team up to hit the beach again - for a beautiful day of over 25 degrees of awesome. Doctor Mud cheated and beat us all there... and was a little quiet about how heavy his pack looked on the way back The place needs a good storm to come through - sand is high and the crabs are buried deep, but there are other mysteries to solve there. Didnt stop some awesome finds including Moa and Shark teeth (and a few small crab "pickers" ) - - oh and more Penguin, winged bird, some nice corals and Little Girl found a small shell that was crystallized inside so she was stoked! Its 9pm now, and still 21 degrees outside, man I love summer! I didnt take my camera, so only have phone snaps but perhaps the others have some more to add! Was a great day guys, cant wait to meet you again. Some careful extraction .... Summer - how many fossil hunters can you spot? @mamlambo in his natural habitat! I found a couple of nice balls.... will be interesting to see if they were worth the carry.

Found a week ago in an area that produces a mix of miocene - pleistocene fossils. I thought of at least 3 animals for this half tooth. Hopefully someone will recognize a distinctive feature.

Coral-ID - Weißenegg-formation, Styrian basin, Eastern Alps (Langhian, Miocene)
FranzBernhard posted a topic in Fossil ID
Waiting for Christkind and(!)/or(??) Santa Claus gives me some time putting together this question: The coral in question comes from the Styrian basin (Weißenegg-formation) and is Langhian/Miocene in age (ca. 15 Ma old). It comes from a very small road outcrop, mainly limestones, north of Heimschuh in the Sausal mountains, southern Styria, Austria. Beside massive, sturdy coral colonies like Montastrea, possibly Favites, etc., another colonial coral occurs in this outcrop, that disintegrates easily into individual sticks or pencils, aka corallites: Outcrop situation, field of view ca. 80 cm. It looks really something strange and unusual. These are individual corallites or they are in the stage of branching; the middle one is about 8 cm high. Sometimes you can retrieve parts of colonies. Remarkable is the large diameter of the corallites, up to 2 cm. With the help of some superglue, it was possible to make some polished slabs of these corals (the matrix is a rather soft marl). Note the highly varying diameter of the corallites and the budding. Especially interesting is the specimen to the lower left. Here, some big (about 2 cm diameter!) polygonal corallites are tightly growing together. But I think, its the same as the other ones. A possible genus that comes to my mind is Acanthastrea. This idea is based on the shear size of the corallites. This genus is know from an outcrop a few km away and also from a similar formation of similar age about 100 km away (Mühlendorf, Burgenland, Austria), the species mentioned/described there is A. horrida. But my idea, that these could be also Acanthastrea could be totally wrong, of course... Thanks for your help and Merry Christmas! Franz Bernhard
