  7. Originally described by Schaal 2004 as Eopython fischeri, the snake was transferred to the newly created genus Eoconstrictor by Scanferla and Smith 2020. Taxonomy from Fossilworks.org Emended diagnosis from Scanferla & Smith 2020: "Medium-sized boid snakes, over 2 m in total length, differing from all other snakes in having the following combination of derived features: edentulous premaxilla with bifid vomerine processes; maxilla bearing four labial foramina and 15–18 maxillary teeth; palatine with five teeth and a long maxillary process; 11 pterygoid teeth; dentary with 18–19 teeth; sharp sagittal keel along the basioccipital; the vertebral column with up to 369 vertebrae, of which up to 72 are postcloacal vertebrae.

  8. I have been too busy to get out fossil hunting when I want but there are a few recent times I've been able to get out. I wanted to try and post a small trip report about them. On October 31 I had the opportunity to visit the W.M. Browning Cretaceous Fossil Park in Prentiss County, Mississippi. Most people from the area are probably familiar with this old site but I'm a new resident to this part of the South so I wanted to give it a try. It's Late Campanian Demopolis Formation. It was a little cold and rainy but warm enough for someone used to North Dakota. Apparently these large concretions erode out of a higher formation. First tooth I found wasn't even in the creek but on the bank where I set my sieves. A good sign. A little tributary carving through the bedrock made for relaxing sounds. A little mosasaur tooth. Washing and drying the teeth back home. "Junk" teeth I set aside to use for biology outreach programs. S Some more pics of the mosasaur tooth. A nice Hybodus cephalic clasper. A chunk of cartilage and some verts. A blunted Ischyrizha rostral spine. Keeper fossils. A couple Baculites asper pieces and some Cadulus sp. didn't get in close pictures. I'm always a sucker for lightning and cool color variations in teeth. Serratolamna serrata teeth were the second most common. Squalicorax kaupi Squalicorax pristodontus Hybodus sp. and Pseudohypolophus. Most were missing tips but the Enchodus were a good average size. Xiphactinus teeth were just tips. Some bigger Scapanorhynchys were also present. Baculites asper and Cadulus sp. Anomia argentia The small Gryphaeostrea vomer. Exogyra ponderosa and Pycnodonte convexa (not pictured) were also a common find. Aside from the common material there were some nice rarer specimens and stuff new to my collection. Overall it was a very good trip.

  12. Hello everybody, can you help me with these? #T1: Carcharias sp (?) or Striatolamia Macrota (?) #T2: Otodus Catticus (???) or maybe, Brachycarcharias Lerichei or Hypotodus verticalis (upper lateral) [On the box was written Otodus Catticus, but I don't know if it belongs to Balegem as specie...] #T3: Brachycarcharias Lerichei or Striatolamia Macrota (?) #T4: ??? I don't have any idea... Thanks in advance:) Gian
  13. Generally, the genus is assigned to the family Amphilemuridae, which according to some researchers is more closely related to today's hedgehogs (Erinaceidae). According to other studies, a closer relationship to the elephant shrews (family Macroscelididae) is also considered for the family. Taxonomy according to Fossilworks. Diagnosis for Pholidocercus hassiacus von Königswald & Storch 1983 (translated from German by oilshale): “A stout, ground-dwelling animal of a good 35 cm total length (head trunk just under 20 cm, tail a good 15 cm). In biological adaptation type, it is comparable to recent hair urchins (Echinosoricinae). Scaly dermal ossifications in the tail region; long bristly dorsal hair; probably possession of a horny plate over the forehead, the extension of which is indicated by deep vascular grooves on the skull roof; split terminal phalanges. I1/, C1/ and the persistent dP/1 relatively enlarged: C/1 premolariform; P/4 with dominant inflated protoconid, very small metaconid, and short broad talonid process; paraconulus and metaconulus of upper molars not connected by shelves to their respective outer styli, and paraconulus not connected to paraconid; lophid-shaped paraconid of lower molars reaches approximately lingual margin of teeth; hypoconulid of lower molars reaches approximately lingual margin of teeth; hypoconulid of lower molars located approximately median and somewhat prominent distally. See also emended family diagnosis.” Identified by von Königswald and Storch 1983 (this is one of the paratypes in their publication). In 1978, the Senckenberg Museum in Frankfurt organized a special exhibition "Fossils from the Messel Pit". The same fossil was in many exhibits that the museum had which included fossils borrowed from other amateur collectors.

  14. Hi guys hope everyone’s having a great Easter, if you celebrate it. A few days ago I got to go fossil hunting for the first time in monthswhile it wasn’t the most productive as the beds were covered by sand and not much erosion had taken place but I found enough in some micro matrix I bought home to warrant a trip report The geology of bracklesham bay To the left, the yellow is wittering fm. Some fossils can be found here but not many. The best area to hunt is the green earnley fm. Which produces the most abundant fossils, here is a photo of it when exposed the fossils to clay ratio averages out at about 3:1 in some beds! on this hunt, the area I focused on was the E5 palate bed, but I found a lot from the turitella bed and the nummulites bed to the right, is the marsh farm fm, this is good for finding fossil corals, such as this anyway, a good source of info is this great video on YouTube, where I got a lot of this info from for identification of fossils, I like to use this website http://dmap.co.uk/fossils/bracklesham/vert/brackvert.htm There are some great specimens to check out on there, but not all species at bracklesham bay are listed there we set out at 3 in the afternoon to be at the beach 2 hours before the 6:30 low tide, at bracklesham the best hunt is on the falling tide. It was a glorious day, not a cloud in the sky, when we got there, we even went in the sea! Not for long though, as we all would get frostbite. Soon the hunt began. here are some pics of the site and me not much was found in the first hour and a half, only a few small ray bars, the most common vertebrate find here, and this luck would sadly continue, it was a very poor day for hunting sadly, I was the only one on the beach that day out of 4 others that came out with anything other than shells, sad considering on a good day you can walk out with 50-100 vertebrate bits, at bracklesham you are at the mercy of nature I guess After an hour of little luck, I found something that made my day, a very rare bone, anything other than sharks and ray is very hard to come across here, in my time collecting here; I’ve seen 3 people walk off with an auriculatis but only 1 other with a complete bone like this, so I’m super happy it has been identified as trionyx marginatus. after half an hour more of not finding anything, I went to collecting matrix as I wasn’t finding much. I have run out of time to post now so I will put the rest of my finds up later today
  15. Hi everyone! Today is received a bunch of unidentified fossil shark teeth found in a now closed sand quarry in Lede Sand, Lede Formation, Balegem, Oosterzele, Belgium (Eocene, Lutetian, 44 mya). I was hoping some of you might help me out with confirming the ID's of the teeth. I have some idea's what the ID might be, but I am not entirely sure about most. Tooth 1 & 2: Definiatly Sandtiger teeth with fine stiations on the crown. That makes me believe that these are probably Striatolamia macrota Tooth 3: Same goes for this one, I also believe this might be Striatolamia macrota Tooth 4: My favorite tooth of the bunch, I am doubting between Brachycarcharias lerichei or Hypotodus verticalis (Upper lateral) Tooth 5: No stiations and a worn cusp 3 mm away fro the base of the crown Hypotodus verticalis? (Upper anterior) Tooth 6: Hypotodus verticalis? (Lower anterior) Tooth 7: Either Hypotodus verticalis or Jaekelotodus robustus Teeth 8 - 11: Brachycarcharias lerichei? Tooth 12: Not sure about this one, maybe Macrorhizodus nolfi anterior tooth or Parotodus sp.? Tooth 13: Looks closest to Xiphodolamia ensis Tooth 14: A tooth with cusps and striations Striatolamia macrota? Tooth 15: small cusps and striated Striatolamia macrota? Tooth 16: I have not really a clue which one this could be. Tooth 17: either Odontaspis winkleri or Brachycarcharias lerichei Tooth 18: Physogaleus secundus Tooth 19: Physogaleus secundus Tooth 20: Physogaleus secundus Tooth 21: Physogaleus secundus Tooth 22: Not sure about this one either. Could it be Jaekelotodus sp. or Paratodus sp.? Tooth 23: Striatolamnia? Tooth 24: Striatolamnia macrota Tooth 25: No sure either it has a weird root and no cusps, maybe Macrorhizodus praecursor? Tooth 26: Brachycarcharias lerichei Tooth 27: Sand Tiger, but which? Tooth 28: Odontaspis winkleri or Carcharias sp. or Hypotodus verticalis? Tooth 29: Brachycarcharias lerichei Tooth 30: Brachycarcharias lerichei Tooth 31: Brachycarcharias lerichei That were all of them, I hope I wasn't too far off with some. I look forward to reading your imput. Thank you in advance!

    Modern cuttlefish jaw?

    Hi guys, found this a while ago, I assume it is modern as it seems to be too soft to be mineralised but thought it was pretty cool anyway, found in bracklesham bay, it’s definitely some sort of cephalopod jaw so cuttlefish may be the only option
  17. Hi everyone! A couple of weeks ago I aqcuired some microfossil samples, one of which was a sample from the Lede Zand, Lede Formation, Oosterzele, Belgium (Eocene, Lutetian, 44 mya). The sample is very rich in Foraminifera & shell fragments, but I also managed to find a tiny shark tooth. While I already searched at belgiansharkteeth.be I can't seem to find a match, perhaps due to it being so small. So I was wondering if anyone here might be able to help me out, I would be very gratefull. Thank you in advance!
  18. Hi guys i haven’t really seen a topic where people shared associated dentitions, if they have that would be cool to know this can be any sort of animal and any amount of association ( ie im not talking about a whole shark)! Here is my first contribution have fun!

    French lutetian fossils

    Hi guys these teeth are from an old, closed location I’m be in France and I couldn’t find any description of the fauna, they are lutetian, so I have based my ids of some English localities I’m more familiar with 1. I think some type of parotodus? 2.galeocerdo latidens? 3. isurolamna inflata or brachycarcharias lerichei?

    Help with shark tooth

    Hi all. I need help with this shark tooth. It comes from an European Lutetian. After doing some research, I have found the genus Macrorhizodus as a possible candidate, but my knowledge of these critters is very limited. Can someone help me? Thanks in advance

    Some chompers in need of a solid ID

    Hi guys I have 2 teeth that I can’t id, Im posting 1now and the other later, this one is lutetian, Selsey sand fm. Unit L4/5 Bracklesham group, from lee on solent
  23. Notidanodon

    Lutetian tooth

    Hi guys found this earlier today and it isn’t the usual striatolamia or other sand tiger teeth, it reminds me of physolageus segundus or maybe abdounia beaugei from the ypresian London clay , however I’m not sure if those species were around in the lutetian, any help would be greatly appreciated thanks also sorry for lack of scale I’m away from home and don’t have a ruler it’s about 3/4cm slang height
