  1. Sauropod19

    Andalusia, AL vertebrae

    Hi all! I made a journey down to Point A Dam today (despite high river levels) just to shuffle about. I came across these two vertebra, the smallest of which is clearly a fish, but I’m not quite sure what the other is. Cetacean? If you have any info on either, please share. Thank you! P.S. I somehow never have a ruler with me so I used the lines of a college ruled notebook, which are separated by 7.1 mm, as a makeshift scale. I apologize for this. 1: 2:
  2. Yesterday I went to Eastern AR to an Eocene outcrop exposed in a creek. I found about a dozen Venericardia planicosta clam shell fossils and a Mennerotodus shark tooth!
  3. Just sharing some Fossil Brittle Stars from the Eocene era. Found in remote area of Upper Sespe Creek drainage of the Los Padres Mountains in Southern California. Fossil site location help credit to R. L. Squires 1994 paper on Macropaleontology of Eocene marine rocks, upper Sespe Creek area, Ventura County, southern California.
  4. Hi, appreciate any ID help on this one from Chivo Canyon in Southern California. About 4-5" in diameter found inside of a roughly 1 foot diameter rock. The area is known for Eocene and Oligocene period fossils. Guessing this may be a sponge, coral, or possibly echinoderm like a Sea Urchin. Stumped on the ID so far. Most of the other fossils in the canyon are mollusks and gastropods. Thanks! -Chris.
  5. Just posting some pics of some finds from Chivo Canyon from 2020 and 2024. Would really appreciate any ID inputs on the Unknown Fossils especially the roundish one with many circles in it. It was roughly 4-5" in diameter in the center of a roughly 1 foot diameter rock. Guessing Sponge, Coral, or may an Echinoderm like an Urchin. The Chivo Canyon area is known to have fossils from the Eocene, and Oligocene periods. There are also a couple other unknown fossils which could be bones but not sure. The Tower Snails or Turritellas are probably mostly Turritella Uvasana. I don't know what the other Gastropods are. Thanks in advance for any ID ideas! -Chris.
  6. For a little while now, @Mikrogeophagus and I have been trying to meet off the forum and hit some spots together. With spring break ending yesterday, we finally found the perfect opportunity before our classes resumed. Tyler had recently singled out a promising locale for middle Eocene crabs, one that neither he or I had visited. As it later turned out, I had passed by the spot before but never committed to its investigation. I was pleasantly surprised at its serenity, and Tyler and I found easy conversation as we weaved through beds of touch-me-nots and waded through silty waters. Our first efforts were concentrated on a small tributary that branched off and reconnected with the main stream. We knew we were looking for concretions, but did not know the nature of them and assumed most would be duds. It was with that attitude that it smacked open my first concretion of the day, decimating a crab inside! While certainly disappointed, we were both enthusiastic about the find - it meant we were in the right place and we now knew what to watch out for. Concretions started popping up quickly, sprouting out of the black banks like earthen easter eggs. Many proved fruitful, with a surprising proportion containing the crab Harpactocarinus americanus. At the time, we didn't know the name - content with just the thrill of discovery in a beautiful setting. We soon discovered some crabs were robust enough to have survived the currents of the stream and could be found in gravel - though just their carapaces. We each claimed one side of the bank and enjoyed success, while occasionally checking the gravel islands between us. One of my favorite finds was this unsightly avocado shaped concretion, bearing a claw that promises a beautiful specimen inside: Displaced carapace found among roots on the river bank: Notice the eye holes! Harpactocarinus americanus wasn't the only critter of note at the locale: Giant gastropods were found in unusual proportion compared to the famous Whiskey Bridge locality of equivalent age, but there was a conspicuous lack of shark teeth. Deep into the hunt, Tyler did find two - one irrecoverable blade in a concretion, and a smaller Negaprion(?) to act as the only success on the fossil vertebrate side for the day. Soon after, Tyler found a large Belosaepia ungula prong, shown here from its underside. These are uncommon cuttlefishes that had a horn (called the "prong") growing on its backside like a short, stiff upturned tail, a character that can still be seen reduced and vestigial in some modern cuttlefish. The hash around this spot was thick - so choked with shells that it resembled asphalt in some places: The site even had a nice sampling of extant fauna - a small Thampnophis proximus (western ribbon snake) could not escape gentle capture, and an alligator gar jaw laid out by recent currents caught my attention. I decided to hang on to it - it may prove a handy reference for general fish anatomy. One of the final finds of the day after a long stretch of barren ironstone was another H. americanus, peeking out of hard iron stones and covered by moss. I pulled it away easily, and upon turning it over was met with a beautiful sight: Look at that pincher! And so concluded a successful scout with a new friend, right as storm clouds rolled over and the first heavy drops of rain fell. Tyler and I walked back to our cars with an aura of victory, and I gave him another concretion. I'm excited to see the results of his upcoming freeze-thaw cycles. May y'all enjoy quality preps and fruitful hunts this spring!

    Callianassa sp.

    From the album: Texas Eocene

    Very tough ID- but settling on a species of Callianassa, and C. brazoensis is the species found in the Crockett member of the Cook mountain fm., so perhaps C. brazoensis. Callianassa are a still extant genus of mud shrimp. Middle Eocene Texas (Whiskey Bridge)

    egg cluster

    This was found at the Stonerose fossil site in Washington state. The onsite curator identified it as an questionable egg deposit. I would like to get a definitive id. The entire cluster is 1cm across.

    Haile Quarry, March 3rd

    I added a couple of threads on Activities connected with FPS field trip to Hallie Quarries in the vicinity of Newberry, Florida. I have some photos of the Quarry to provide a sense of what it was like and some additional finds. The Quarry I visited is just one of many at this location. and the one I was in... huge. A wall in the distance, heavy movers to stay far away from, a "tiny" FPS member searching the low wall ahead. I am walking around this mountain of rock on my left , searching for fossils that may have fallen down the cliff face. I am very careful the few times I attempt to climb the cliff face reaching for a fossil just a little too far away... There can be great rewards... Gorgeous, and and there are lots of potential shell, and echinoids in this semi hard rock, I have a rock hammer and trowel. Can I possible get this out in one piece.. I have already broken others or found that they were already broken before my arrival. So I decided not, and just walked on with a photo and a memory. As I continued around the mountain, I came to this site , took a step forward, and quickly stepped back . A sinkhole about 4 feet across, and with a single glance inside I saw it was at least 25 feet deep. This one is not particularly large. The Quarry has lost a number of large earth movers in sinkholes. This is where I recall signing the waiver stating that I am totally responsible for any of the various dumb things I might do while hunting for fossils and hold the Quarry owners blameless for any/all damages to my body. Roger Portell was our guide and Advisor and we moved a couple of times to locations that might provide different fossils. The last stop was supposed to contained marine (shark teeth) and mammal fossils. As we stepped out of our vehicles, Roger showed us another sinkhole, advised us to be careful , and described recoveries of mammal bones and teeth from this area decades past. I was fortunate to find one of those teeth, described in this TFF thread. https://www.thefossilforum.com/topic/139986-love-the-surprises/#comment-1479029 It was laying on the ground 5 feet to the left of this sinkhole. Sometimes I am just blessed in the right place at the right time. Here are some other finds of the day, with what ever I currently know about them... 1) M. americanum , a Sea Biscuit, approximately 4 inches in width, encased in matrix. 2) What I refer to as Jingle shells, and a small Echinoid...On the Echinoid, I have to wash, brush , scrap off some of that concrete like matrix to figure out what it is.... 3) A couple of Oysters... there few shells free floating from the concrete like matrix like these. 4) More shells, this time in Matrix 5) Did I mention Endocasts ? All over the place.... Sometimes hard to differentiate from shells. 5a) This one reminds me of a cowrie.... but not like any modern or even fossil ones that I have seen... I had previously found exactly like this one in a bone valley creek.. Would like to Identify.. Hope you enjoyed the trip. Comments always appreciated.
  11. From the album: Fossils

    2.4 inch Otodus aksuaticus shark tooth from the Eocene Nanjemoy Formation of Maryland. This is a good example of the transition from obliquus to auriculatus, with serrations extending about halfway down the crown.

    Bracklesham 10/2/2024

    Quick trip report from a rather unsuccessful trip to bracklesham bay. On the lowest tide of the year I was hoping the formation would be exposed but over a metre of sand lay on top of it still. I think some onshore winds had been conspiring against me! However it was fun to hunt and I was rewarded with a beautiful sunset! 1. spot the fossil 2. sunsets 3. total finds 4. brachycarcharias lerichei 5. striatolamia macrota
  15. From the album: Fossils

    1.5 inch lamnid type shark vertebra in matrix from the New Bern quarry. Not sure if this is from the Oligocene River Bend Formation or the Eocene Castle Hayne Formation. If you think you recognize which formation this is from, leave a comment.
  16. My family and I went on a trip to Yellowstone, the Green River Formation and the Blue Forest in Wyoming. Although my son found by far the best Blue Forest specimen, I thought smaller specimens were also of interest. The attached image illustrates a common theme of the petrified wood specimens. Typically, the outer bark results in a fluffy white deposit of calcium carbonate. The inner bark is often composed of what the locals refer to as "blue opal" (likely chalcedony), and then the center part appears to be silicified wood. Some specimens had iron oxides as well. I highly recommend a trip to the Blue Forest. It is very out of the way and directions are hard to find. The directions we found at one point stated that we should turn left at the gravel road with a rusty barrel at the intersection. We traveled down the gravel road for many miles until we spotted dig sites. It is very remote and you would want to make sure you vehicle is in good condition with plenty of gas and that you have plenty of water.

    Possible coral fossil?

    Found this today by a river in Eastern Texas. Wondering if it could be a coral fossil?
  18. Howdy! I found this fossil on a river bed last Fall in eastern Texas. I did a little research and it looks like this region is known for Eocene epoch fossils. I think its a vertebrae (or piece of a vertebrae) but can't seem to ID it beyond that. Any thoughts? Thanks!

    Shark teeth ID help

    Hi. I'm a final year undergraduate student doing my dissertation on sharks. There are a few teeth I found which I feel I should be able to identify given some features preserved, and I don't want to just leave them as indet. They were found at Walton-on-the-Naze, UK, from the lowermost London Clay Formation, Eocene (Ypresian) in age. All photos show teeth in the best view that I could capture with me camera/have most of the specimen in focus. Scale bar on the right = 1cm. For all teeth they are in lingual (left), labial (middle) and mesial (right) views where applicable. Apologies for the lateral photos being so blurry, didnt get the chance to run them through focus stacking Thanks in adavance. Also, if people want to ask me any questions on the disso feel free to.

    Morocco 2023 Geology Trip

    I was fortunate enough to be able to visit Morocco last year in May and tour the wonderful geology of the country. This will be a very short recap of the experience because frankly there are just too many things to share. For starters, the culture is fantastic. Morocco consists primarily of the Berber people and they are some of the friendliest people I've encountered. Very welcoming and ready to share some tea with you. Tea is by far the most common thing you will drink in country. I'm quite certain there were days that I had tea at least 8 separate times, and the tea was fantastic. If you've never had Moroccan tea then you are missing out (the mint tea in particular is wonderful). The cuisine is beyond amazing, and there honestly wasn't anything in country that I didn't like. Trying to replicate some of the foods has been a challenge (my tagine is getting close), but I suppose that just means I'll need to return some day. The country is also very safe throughout. As a solo female traveler, I felt comfortable at all times and was not concerned. However you should know that few people speak English. The most common languages people know are Arabic, French, and Berber, so there was some language barrier but as with most things, it was doable. My arrival to Morocco began in Marrakech where I was met by my guide who drove me out of the city, through the Tizi n'Tichka mountain pass at 2200m in elevation. Eventually we made our way to Tamdahkte and I stayed at a wonderful riad that was (as I would come to find out) quite open air just as most riads and buildings are in Morocco. On the way we stopped at a salt mine and walked through.
  21. This was my first winter fossil hunting in NJ (or anywhere, as a matter of fact). Definitely a different experience from summer and fall. Less people, and much better fossils! Although the people I have run into were pretty devoted, which I can appreciate. Thought I would document my 4 hunts between December and this past weekend. First up, 12/16. On of my favorite Cretaceous brooks. Found an awesome variety of fossils, one of which turned out to be a Theropod tooth!

    Hypsiprisca sp.

    Juvenile Priscacara can be easily distinguished from juvenile Hypsacantha by their distinctly rounder body shape. Grande distinguishes two forms of Hypsiprisca: Hypsiprisca hypsacantha (originally described by Cope in 1886 under the name Priscacara hypsacantha) and a second yet undescribed, closely related form Hypsiprisca sp. H. sp. is more common than H. hypsacantha: H. sp. are mostly very small individuals less than 60mm long. Quotation L. Grande (2013): "The second species that remains undescribed differs from H. hypsacantha in being more slender-bodied and having a more convex posterior tail fin margin (H. hypsacantha has a very slightly forked tail margin)."
