Ova sp. Mykolaiv Sands, Fore-Carpathian Depression Middle Miocene (16-11 Ma) Gleboviti Locality, Roztocze Hills, Ivano-Frankivsk Oblast, Ukraine Acquired from online, August 2023 I had previously identified these as Schizaster sp., but I realized a short while later that the larger specimen only has two large gonopores, and while the one in matrix has an incomplete apical disc, it looks as if it may have those same two large gonopores. Therefore I'll consider them Ova sp. for now, the larger one seems to have the complete lateroanal fasciole from what little I can see. These come from the same beds that have plentiful spine-coated Echinocardium leopolitanum. One specimen has some spine preservation on the oral surface, while the other one in matrix has some spines along the anterior edge, as well as seemingly on much of the oral surface as well, based on a small crevice located in the sandstone that exposes some of them.-

Echinolampas sp. Ternopil Beds, East European Platform(?) Middle Miocene (16-11 Ma) Unknown Oblast, Ukraine Acquired from online, August 23 My source on Ukrainian echinoids had no info on this specimen other than it seemingly came from the Ternopil Beds, and I have not found any reliable source of information online as to what species this could be. The only thing I could find was a mention of a different undescribed specimen of Echinolampas; however, it was very rounded (not unlike the Oligocene Echinolampas aldrichi from North Carolina), and not laterally compressed and elongated like this one. I wonder if this is a different undescribed species from that one. It measures around 6.6 cm (2.6 inches) long, and around 4.4 cm (1.725 inches) wide. The oral surface is depressed slightly inwards towards the peristome. It seems that the oral surface was prepared with vinegar due to a faint smell, although fortunately it doesn't seem to have suffered much acidic damage.-

Clypeaster scillae Weissenegg Formation Middle Miocene (16-11 Ma) Retznei Quarry, Retznei, Styria, Austria Acquired from a collector during a local trade show, September 2023 While this specimen is ever so slightly crushed, it is also unusually laterally compressed, and the aboral surface is heavily deformed, while the oral surface is mostly normal. Thus, to me it appears to be a pretty pathological specimen.-

Clypeaster gipplandicus Bairnsdale Limestone Middle Miocene (16-11 Ma) Nowa Nowa, Victoria, Australia Acquired from a collector during a local trade show, September 2023 This specimen has some nice plate division, but most of the apical disc is missing. This specimen is almost twice the size of my first specimen of this species.-

Parascutella gibbercula Ternopil Beds, East European Platform Middle Miocene (16-11 Ma) Stare Porichchya, Kolomyia Raion, Khmelnytskyi Oblast, Ukraine Acquired from online, July 2023 While most of the Parascutella gibbercula I've received come from the Ternopil Oblast, according to my source of them these detailed, "textured" specimens come from the Khmelnytskyi Oblast instead. This is probably my most detailed one I've acquired to date.-

Hi all, I have a mostly intact pelvic bone of a large camel species. Unfortunately, it was found just and inch or two below the surface in a quite soft sandstone that was mostly sand. As a result the side closest to the surface is in quite poor shape, especially near the obturator foramina. I have used paraloid B-72 throughout the prep to give some strength to the bone and some superglue in the larger cracks, but as I have removed most the matrix, this is quite the fragile piece. Any suggestions on how best I can proceed? I know paraloid isn’t best for heavy weight and I don’t want to paint superglue all over it-unless that’s what’s needed.

I have a snail here from the Middle Miocene Chipola Fm of North Florida. I thought I knew its ID, but I recently looked at it again. I thought it was Xancus chipolanus (Dall). Can anyone here help with an ID?

Hi, This skull (photographed on display at a museum in China) is labeled on Wikimedia Commons as Zygolophodon, but it's unclear what species of Mammutidae it represents. It could be an Asian species of Zygolophodon, or it could be Miomastodon gobiensis or another Asian Miomastodon species. Anyone curious what species the skull represents?

Here is what you may find during an 8 hour tour at sharkriver located in Monmouth county,N.J. The water here is a little deeper and the fossils may be less than a Cretaceous Brook.

My first visit to Fossil Beach at Mornington Victoria today. I found this piece of fossilised coral. I know the finds from this area date to the Middle Miocene period (10-15 million years old) but I was curious as to whether this would date from that period too?

The Chesapeake Group has at least 16 different species of otoliths (from bony fish) that fossilized. I still have at least a thousand otoliths left to sort. So far I only have five different species (I think). I have already searched over a thousand otoliths in material brought back in just four trips to this middle Miocene (Calvert formation) site. Here are pictures of the five. If I find any additional species I will post them. 1. Micromesistius cognatus (a genus of cods) 2. Trisopterus sculptus (a genus of cods) 3. Genyonemus sp. (a croaker) 4. Pogonias sp. (a black drum fish) 5. Sciaenops sp. (a red drum fish)

This weekend I went on another fossil hunting trip with my dad. We went to a place called Bacchus Marsh which is around 65 km east of Melbourne. Here we went looking for Tertiary plant fossils such as Laurus and Cinnamonum. The site was a creek bed under an old bridge. The bridge was located next to the Western Freeway which connects Bacchus Marsh to Melbourne, and extends north to south, eventually emptying into the Werribee river (about 2km away). The creek also goes under the freeway through two tunnels and you can look for fossils on both sides of the freeway, but the side near the bridge had the best rocks. The rocks we looked for were Ferruginous sandstones which are late Paleocene (59 million) to Middle Miocene (14 million). The creek was dry and it didn't look there had been water in it for a long time.

Hello, Today I went fossil hunting down at Fossil Beach which is located on the Mornington Peninsula, Victoria, Australia. I have been there a few times before, but it always fun and I always find some good fossil specimens. The formation there is known as the Fyansford formation which is middle Miocene (10-15 miilion years old). The weather was beautiful and warm, with no wind at all and almost flat seas. Daniel. Everything I found. Gastropods Gypsum Crystal

Hi I have currently had some trouble indentifying some ichnofossils from this middle miocnen place, but I have ended up facing a big dilemma... There are some pieces which do not have bony structure, at least on their surface , but I cannot identify with any ichnofossils type(pupal chambers, burrowings, galleries...). I have started to think actually whether or not I am facing vertebrate bones, although it has always been my last idea in mind. The facies is continental and there have been findings of turtles, mastodonts and some equids nearby. I do not want to related these pieces with them but I jaut dont think geology can erode in these forms so many rocks in a 10 square meters area... I post now some photos, and thanks in advance

Hi everyone! I'm having some trouble classifying some ichnofossils which date back to the middle Miocene. They come from lacustrine/low-energy continental waters. If it helps, I've already identified some other ichnofossils in the area such as Celliforma, Planolites, Psilonichnus, Scoyenia, Palaeophycus, Teisseirei, Camborygma... This first photos are gallery "dead ends" which from my point of view share many caracteristics and should be a recognised ichnogenera. They show striation lines in the ventral part, some kind of "leg dragging" This second set seems like pupation chambers to me. They share some characters with Rebuffoichnus but I don't know for sure what it may be

My son, Sean, treated me to a trip at the famous Ernst Shark Tooth Hill Quarry. We spent a total of two full days digging and about an hour sifting but the wind was to strong to be productive. The dust there is like fine powder, didn't know the human ear could hold so much dust. The rest of the trip was fantastic, mild temps and calm wind. Everyone wants to find that elusive Meg. but not the case for us Texans. I did find a lower Hemipristis which are very uncommon at the site. Pictured are my finds of two days digging, lots of Isurus planus and one 2 1\2 l.hastalis also a whale and two dolphin ear bones. Found some smalls as well, one Squatina and numerous dog fish teeth. Salvaged several teeth that were in matrix, makes neat display. Some of my finds suffered on the jet flight back to Dallas so next time will bring better packing material. Pictured are four colorful teeth from the West private quarry that can be seen behind the picture of Sean and me. They are totally different in color and better preserved, was lucky enough to meet the co-owner of the quarry and he sold me a couple of teeth, would love to hunt that one. Would I do another trip to Bakersville, Calf. Absolutely in a heartbeat, the Meg. still waits for me but thankful for the teeth I and my son found.

Hello, I'm new in this forum I'd like to start up with a question about a molar teeth I hope some of you could answer I found this tooth in middle Miocene strata, and I don't know what it is. The first thing I thought was that it was just a simple tooth from a present animal, but I can't math my tooth with wolfs, foxes nor dogs. I thought then about it being Miocene old and I wonder if it could be Amphicyon or Hemicyon, which I know that have been found in a nearby locality. I can't found enogh material on the internet to clarify this, so a little help would be awesome. I think it is a milk tooth because the root nor any signal of it has been preserved. Thanks in advance!
