  1. M Harvey

    pelecypod ID

    These were found in Western Alabama in the Demopolis Chalk. They appear to be locally common. they are very delicate and hard to find intact. Hoping to put a name to the face and organize my collection.
  2. The Rio Puerco Valley was my introduction to fossils. For many years now, I have scoured its Late Cretaceous shales and sandstones in search of ammonites. Somewhere along the way, my fascination with the ornament grew into an investigation of its environment. Last week at the New Mexico Geologic Society's Spring meeting, I made my first venture into the world of paleontological science. With the help of Dr. Spencer Lucas of the New Mexico Museum of Natural History, I presented a poster/abstract (Foley & Lucas 2017.pdf) exhibiting my ideas. I received some criticism for incorporating ammonite ornament and caught some grief for including a labeled map...otherwise, this was an amazing learning experience and I am ready to move forward. Back to the rocks!...I have a paper to write. Blue Hill Shale: Spathites puercoensis: Prionocyclys hyatti: Coilopoceras springeri:
  3. Too lazy to translate it myself, I just put the finished pdf through the google translator : Fossilien_2023_21052023_E.pdf Some, but not all, formating is lost, though. And its just one page of text besides three pages of pics. No worries about the detailed site map, as we already know, nobody cares about rudists . Here is the link to the original, German version, for our German speaking members : Fossilien_2023_21052023 (pdf, 3.4 MB, personal homepage) Here are the original pics: Have fun ! Franz Bernhard
  4. At last week's NJ fossil show, I purchased one fossil, a cretaceous fish with an unusual feature. It is a Coccodus from Lebanon, its length is 6.5 inch (16cm) and dates to 95mya. Coccodus is a pycnodont, an extinct group of fish which lived from the late Triassic to the late Eocene. A pycnodont primary characteristic is molariform teeth, rounded and blunt, suitable for crushing shellfish amongst other prey. This specimen appears to be split with the dorsal surface exposed. What caught my eye is that most of the dentition appears intact, with a bones forming a maxilla and “palate” vault-like structure rising above the plane of the specimen. It would be remarkable to reveal both upper and lower dentition within (course I’d probably ruin the fossil). Note the bizarre shapes of the teeth that are exposed.

    Turonian echinoid

    I recently found an echinoid in the Prionocyclyus hyatti ammonite zone of the Upper Cretaceous (Middle Turonian) Semilla Sandstone Member of the Carlile Shale. These creatures are not common and until now... ...I have only found fragments. After a quick clean and some photos, I wonder if there is enough diagnostic material left on this crushed and eroded specimen. scale= 1/4" I do not know much about echinoderms, but I am very much interested in learning more. Is there enough of this creature to label a genus? Thank you for your help.
  6. We talk a lot about the aquatic nature of Spinosaurus well here is a dinosaur whose streamlined body is a major adaptation for aquatic animals to move efficiently in the water. Natovenator polydontus from the Upper Cretaceous of Mongolia. https://www.nature.com/articles/s42003-022-04119-9 https://www.smithsonianmag.com/science-nature/worlds-first-swimming-dinosaur-discovered-in-mongolia-180981217/#.Y4jcTsmaCbk.twitter

    Mystery Fossil Lumpkin, Georgia

    I have a real mystery fossil I found in 2004 from Lumpkin, Georgia. The formaton is the Upper Cretaceous Ripley FM. US 27 was being 4 laned and quite a bit of new material was exposed in the road cuts. I think I was within a quarter mile of either side of the well known Frog Bottom Creek Upper Cretaceous fossil site. I found Exogyra costata, Flemingostrea subspatulata, Pycnodonte mutabilis, casts and molds of gastropods and pelecypods,worm burrows, etc. The oysters have well preserved shells, and the rest of the shells are mainly impressions and casts. Originally I just glanced at the mystery fossil and thought it was a impression of a pecten and set it aside. I'm now organizing my fossil collections and upon closer inspection I realized it wasnt a shell impression. Any guesses on what this is? I have never seen anything like this in my lifetime of collecting.

    'Moose' the mosasaur

    I had the opportunity and good fortune to participate in the excavation and preparation of a mosasaur this past year. The specimen was discovered by a new friend, Allison, in a small unnamed stream adjacent to family property in east-central Mississippi (? Prairie Bluff Fm, Upper Cretaceous, Late Maastrichtian).Allison found the first bones in early May and contacted me for help in identifying the bones through a mutual friend. I'm far from an expert, but was able to ID the bones (a radius and vertebra) as mosasaur. She was really excited, since the bones were her first vertebrate fossils other than a few Pleistocene horse teeth from the same creek, and promised to continue searching. On her next trip, Allison exposed part of a mosasaur jaw and sent pics to me while still in the creek. Long story - short version -- We (Allison, my grandson, Logan and I) began serious excavation in early June 2018 and continued collecting (several trips) and preparation through November. Dr. Lynn Harell, Paleontologist with the Alabama Geological Survey viewed photos of the specimen as I prepped them and helped to ID individual bones and confirmed the genus as Mosasaurus. Dr. Takehito Ikejiri, Alabama Museum of Natural History, worked with me to compare "Moose' (named by Allison) to many specimens in the archives of the Museum. Both were extremely helpful to me as we tried to confirm the ID and agreed that it should be labeled as Mosasaurus sp. until further study. George Phillips of the Mississippi Museum of Natural Science identified associated invertebrate specimens in hopes of confirming the geology of the site (still unconfirmed). 'Moose' was donated to the Dunn-Seiler Museum at Mississippi State University in December 2018. It will be studied as part of a graduate students research. Following are a large number of photos documenting the site, excavation, prepration, and bones of 'Moose'. Thanks for looking.
  14. Hello, I would like to give a away some Gosau-fossils from Austria, Styria, for free. Mainly hippuritid rudists, some Trochactaeon snails. I don´t want anything in exchange, shipping is free. If you like, you can donate a small amount to TFF after you have received the fossils, but that´s not obligatory. Please pm me, if you are interested. Thanks. Edit: Closed! Several people have already pointed out their interest in specimens. I am likely to run out of stock . Good thing!! Thanks for all your interest! Franz Bernhard
  15. Hello, last Saturday (10/09/2021), I visited again some classic fossil sites at Waagraben, Hieflau, northern Styria, Austria with a friend. These sites are known since around 1850, are probably of Coniacian age and belong to the Gosau-group. First, some maps: Overview with location of Waaggraben in Styria, a geological map from Ampferer, 1935 (1 = rudists; 2 = Trochactaeon; 3 = Conglomerate quarry), topo-map, and DEM. These sites are very well known, so no problem to pinpoint them exactly on maps: On the way. We will meet this guy in the background near the car again: Conglomerate quarry: First, we visited the surroundings of a historic conglomerate quarry, first mentioned in 1509 and intermittently worked until 1974. It worked an interglazial, well cemented, mostly white conglomerate, used as high-quality building stone or mill stone, but sometimes also as decorative stone. This are the remnants of the old smithy, the quarry itself is heavily overgrown: View back with some houses of Hieflau, to the left some remnants of the smithy: Rudist site: Lots of rudists (mostly hippuritids, some radiolitids, few plagioptychides), mostly found at both sides (shoulders/berms) of the forest road. This time I focused also on specimens with large diameter (Vaccinites) and we found a few. (I have seen one from this site in a collection, but have not stumbled upon one during my last visits from 2014 to 2015. But when you know...). The rudist outcrop near the road is also still there and untouched. Found also a few Plagioptychus, but they were not my goal. Lots of rudists also in the steep forest below the road, coming all from periodical road cleaning/grading. Funnily, the furious forest ranger showed up (we knew already that such a crazy guy is around in that area). He shouted: "No digging, no digging!! I have your car number." "We are only looking at the road." "A fat lot I care about that (Nice translation of Styrian "Das ist mir wurscht!"), but no digging, no digging, I have your number." Turning around and escaping with high speed. Such a crazy guy . Overall view from southeast and northwest, respectively. A little bit to the upper right from the center of the second pic, you can see some old diggings. This is what the guy was crazy about: "No digging!!". But I can understand, look at the tall outcrop of rudist limestone above the road. Severe undercutting not recommended! At the red X is the "permanent" rudist outcrop at the forest road: Rudist outcrop at forest road, its composed of Hippurites species. There exits a master thesis from 2015 about this site and the surrounding, if anybody is interested: Waaggraben Rudist Limestone (in English, ca. 6 MB, pdf, hosted at Uni Graz): Rudist fragments (mostly Hippurites) below this outcrop, as found: Some crushed pseudocolonies of Hippurites, as found, pseudocolony in second pic is 16 cm high: Trochactaeon site 1: In the year 2014, I found several Trochactaeon in the shoulder/berm of the forest a little bit downhill of the rudist site. Yesterday, dozens of snails showed up, all at the surface of the shoulder. (The driveway itself has foreign gravel spread over it). At one spot, they seem to crop out in the shoulder (red x). I took a total of 6 specimens, how many snails can you spot in the second pic? The host rock of the snails is a sandy marl with lots of white spots, made of an unknown fossil (at least unknown to me). You can see some to the left of the red object in the second pic: Trochactaeon site 2: This is the classic (known since about 1850) Trochactaeon site at Waaggraben. Its situated near the creek and it has changed considerably since my last visit in 2016, because the area above the digs was clearcut some years ago. Due to better lighting, the steep hillslope is now quite heavily overgrown with grass and such things, you have to know where the digs have been located. Anyways, just a few meters downstream, a new dig hole has been opened up by someone, and was last visited only a few weeks ago. Lots of Trochactaeon left behind (everything is veeery muddy, not easy to spot), but we took nothing, we had enough. New dig hole (red x) and debris below, veeery dirty, very dangerous (overhang!), no fun to work in that hole: Old dig holes, barely visible: Pic from 2014 showing about the same area with well visible dig holes: View from above with one quite recently activated old dig hole (red x): Here are some polished specimens of Trochactaeon from Waaggraben of my finds from 2014, box is 40x30 cm: Polished specimen with typical "spotted" host rock (sandy marl) Hope, you enjoyed a little bit . Thanks for looking! Franz Bernhard
  16. I purchased these as Ingenia yanshini which I think became Ajancingenia, which then became and is currently Heyuannia. The formation provided is the Djadochta Formation, but that doesn't seem right since Ingenia/Heyuannia is not found there as far as I've checked. Unfortunately, there isn't provenance other than Mongolia attached to them to say whether they come from the Barun Goyot Formation where Heyuannia yanshini is found. While I'm not necessarily doubting the original ID, I just don't really know. I'm not expecting a positive or diagnostic ID to the genus level, but I wanted to at least know whether or not I can label this to Oviraptoridae indet., possibly Heyuanniinae indet. The original ID is a bit of an odd one, but it might have just been one of the few oviraptorids described at the time. Last I checked, there are now tons of recently described oviraptorid genera in Mongolia and China. The pair of phalanges with supposedly the semilunate carpal attached which I think is the smaller section? I know one of them did have glue in-between them when I lightly smeared it with acetone using a cotton swab. They are associated coming from the same sandstone block, apparently along with other shattered phalanges. Although I don't know if these actually came from the same animal since one looks ever so slightly larger. There is some sort of clump of sand or crystalized piece attached, as well as light beige or cream colored matrix. Not sure if that narrows down a formation, probably not, but I do see a lot of matrix from Mongolia tend to be red-ish color similar to the Kem Kem Beds. Any input is appreciated. There's probably a lesson to be learned here . . .

    Bone or Plant?

    Hey folks, hopefully some of you can help me with this odd thing. It was collected back in 2008 from a small exposure of the Pecan Gap Formation, Taylor Group (Upper Cretaceous) in Austin, Texas. It was found in amongst typical marine fossils such as Exogyra, baculites, bivalves, gastropods and a few scrappy shark teeth. I feel like I have seen this before in a book or museum but I have had no luck looking through my own library. As you can see it has a bone-like outer texture but the shape is unlike any bone I know of. But then I am not a "vertebrate guy." All suggestions welcome...

    A plesiosaur tooth from Morocco ...

    ... But I don’t know the genus. It is from the upper Cretaceous, found in phosphate deposits from the Oulad Abdoun basin, Morocco. It is around 6cm in length.
  22. Could not resist collecting some more Trochactaeon snails at Breitenbach-11 in Kainach, Styria, Austria last Saturday (10/10/2020). Especially the upper T-bed contains rather well preserved (for the formation, of course ) snails. But always the right amount of weathering is needed (not too much, leads to disintegration of snails; not to less, they will adhere firmly to the rock). Still some potential there. Worked only with a screwdriver, needed only a few very gentle hammer taps. No prepping, just a short brush with a soft tooth brush. For more info about the area, have a look at my previous post: Trochactaeon - Gosau of Kainach, Styria, Austria - Summary Franz Bernhard
  23. Just a few ammonites from my last hunt along with a cool rock .
  24. Hi all! The Aguja Formation matrix that I ordered from PaleoTex arrived on June 12th, but I decided to wait until school ended before I began the process of searching it. Well, school ended yesterday so I have begun the process today! My 5 pounds of matrix are currently soaking in a solution of baking soda and water (because the matrix arrived "unwashed"), but while stirring up the squishy contents with my hand, I found the following 3 items that I'd like your input on. Item #1: Could this be a ceratopsian spitter tooth??? @Troodon More to follow...
