    Heterosalenia sp. (genus ascertained by JohnJ) Bottom of Unit 2, Lower Member, Glen Rose Formation, Trinity Group Albian (Lower Cretaceous) These odd little Salenids were first noticed by JohnJ many years ago. I was lucky enough to find another slightly larger specimen. This one was hiding in my collection amongst some more common species. These are now being studied and properly described by an actual paleontologist!

  10. Characteristics of the family Pachytroctidae Head: Antennae usually have 15 segments. The first 4-5 segments of the antennae do not have sculpturing; other segments have ringed sculpturing (annulations). Eyes are relatively large, compared to related families. Legs: Tarsi have 3 segments. Hind legs are long and the femur is not flattened (as in Liposcelidae). Wings: Adults can be have full-length wings or short wings, or can be wingless. Full-length wings are held flat over back when at rest. Forewings are rounded. Forewing veins are distinct: Areola postica is narrow, long and flat. Pterostigma is not thickened (as in Psocomorpha). Vein M has 2 branches. Veins Cu2 and Cu1A reach the wing margin separately. Abdomen: Abdominal segments often partially membranous on back surface. Male: Clunium is absent. Phallosome is closed at the base with complex structures on the posterior end. Female: Subgenital plate sometimes has T-shaped sclerite, as in related families. Gonapophyses are complete and hairless: External valve is large without lobes. References: Dany Azar, Diying Huang, Chenyang Cai, André Nel. 2015.

  12. Took me a little while to post this trip report, I'm always a busy person. This trip is from October 3rd, 2020 in Ellsworth County, Kansas at a reservoir. The predominant formation at the site I visited is Kiowa formation; which is known for marsh and delta environments in the early Cretaceous (Albian). I found some interesting things and I'll show below. Possibly some carbonized wood materials. Lignite or coal? It was flaky and would crumble if touched. It left some black powders on my hands after handling it. I found several large pieces of them together and partly encased in concretions. Putting them together would make them about a meter and half long. Piece #1: Piece #2: Backside of #2. Notice the clutches of concretions. ...continued on the next post.

    What happened to this ammonite

    Hello all I have had this ammonite for quite some time now, but since it has been tucked away in a drawer for the last couple of months. There is something weird about this piece however. The front looks pretty normal, except is a bit deformed. But on the back, it looks like the ammonite exploded. Hard to explain so I hope the pictures help. I've heard of exploded ammonites before so I wonder if this is one. Thanks all for your help
  14. Summer vacation fossil hunting week. Like each summer Natalie and I spend 1 week of our holiday for a fossil hunting trip. Usually the destination for this is the Isle of Wight, but due to the current covid situations we had to choose another location. So we went for 1 week to the French coast altering between late Cretaceous and Jurassic deposits.. Although there were no big tide or storms we still got our fair share of fossils in the boulders on the beaches and we even had a few spots of gault clay exposed where we found some nice phosphate ammonites and crustaceans. I’ll let you all enjoy the holiday pictures: Natalie found this exqusite little lobster in situ on the beach on the 1st day: ( Hoploparia longimana, Albian ( Gault clay ) ) soon joined by another specimen. Ichthyosaur vert from the Kimmeridgian: more beach: jurassic ripplemarks: Chalky ammonites in the loose boulders: Mantelliceras sp. : lower Cenomanian Cunningtoniceras inerme Mid. Cenomanian And a large one found by a local collector that we got to take back home ( Thx a lot Luc ) ( Lewesiceras peramplum, Turonian ) And a few pieces after cleanup and prepwork: Albian Ammonites from the gault clay: Gault clay crabs: a few of the chalky ammonites: a nice rare heteromorph: Turrilites scheuchzerianus mid. Cenomanian before and after prep:

    A Cretaceous walk on the beach

    Last Saturday we finally went back to the Cretaceous deposits at the northern French coast. On some spots on the beach the gault clay deposits were visible, this delivered a few beautiful belemnites ( Neohibolites minimus ) and from time to time other small fossils washed out of the clay and scattered in the shingle. The chalk boulders near the clifs were not very productive, apart from a very rare Ptychodus tooth. This one made our day.

    Trip to Folkestone

    Went to Folkestone (Early Cretaceous, Albian) for the second time a couple of weeks ago. Last time I mostly climbed among the big rocks looking in the gaps for fossils but this time due to some poor navigating we accessed the beach from the opposite end this time around. This turned out well though as this stretch of beach has few of those big rocks but good access to the cliffs and slumps. We ended up spending most of the trip picking through the cliff base and fresh fall. This produced some nice ammonites, though it was still difficult to find whole ammonites as is the case with this location. We also found some nice gastropods well preserved, though very delicate, in the clay, as well as belemnites, bivalves and lots of ammonite fragments. My favourite find is the Eutrephoceras clementinum nautilus as I believe they are fairly rare and the colours on it are great. Also the Euhoplites proboscideus is a lovely shade and nicely detailed (Good find boyfriend). ID's are somewhat tentative so if you have any suggestions I'd be grateful. ??

    Brachiopod or Bivalve?

    Kiowa formation and Albian. Approximately 1.3cm long and its quite flat and thin. Not sure if it's brachiopod, more specifically a lingula brachiopod, or a bivalve. Unfortunately the umbo is missing so I'm not sure if it's symmetrical or not. I'm leaning more on bivalve but I would like to read your opinion. What's the lowest taxonomy level you can identify?
  19. A fragment of something; I thought it might be a part of fish spine or decapod pincer. From Kiowa formation and Albian. Approximately 5mm long.

    Kiowa Mysteries

    All from Kiowa formation (Albian). Identifying fossils from Kiowa formation has been incredibly challenging for me the last few months and I would need help on here! These possible fossil fragments have features that made me have second thoughts on whether if it's just suggestively rocks. They are suspiciously of biological origins, but I would like your opinions. #1: approximately 3mm long. It's quite smooth and featureless with some mineral staining. #2: approximately 10mm long. top view bottom view and it's fairly flat ...Continued below.

    Odd Albian Fish Tooth

    Any idea what the tooth on the left is? I know the other two are pycnodontids but I have never found anything like the one on the left. It is very cylindrical in cross section and has the odd "capped" end. Closest thing I could find in my reference library was a diplodicus tooth but this seems way to small. The site is in the Upper Glen Rose Formation (Albian) of Central Texas. This site has produced pycnodontids, turtle and crocodilian bones & teeth.

    Another Glen Rose Vertebrate

    There is a location close to where I work in Central Texas that has produced some pretty nice fossils over time. It is a rather unassuming road cut that at first glance and a quick scan looks like the usual mix of clam and snail steinkerns and mostly busted up oysters. Typical Upper Glen Rose Formation. But early on I had found that it also included one of the upper echinoid marker beds. In Units 6 & 7 there are thin beds loaded with oysters and echinoids. Mostly the very typical Loriolia rosana but also the occasional Coenholectypus planatus or rare C. ovatus as well as Heteraster, Phymosoma and, again rare, Polydiadema. Within that thin layer I would also find bryozoans and crustaceans. As I climbed the cut one day to get to the echinoid layer I came across a fairly decent ammonite as well and that got me to pay more attention to the rest of the cut. Then last year I had a nice talk with a gentleman named William (Bill) Rader who has been doing research for years in our local rocks. You can find his name attached to all sorts of papers on everything from echinoids to crabs. Bill told me to look there for vertebrate fossils, including crocodiles. Well duh, the next time I go I find a crocodile bone (there's a post from me last year on that) Yesterday I decided to put some hours in at the shop and on the way home stopped to see what the recent rains had exposed. I found some Loriolias and then I found this. Any ideas? I have some swags in mind but I have never been a big collector of vertebrate material.
  23. I try to identify any fossils on my own before I post it on here, that's how I learn! Anyway, I found these three shark teeth while pre-washing the matrices from Kiowa Formation (Location: Ellsworth county, Kansas. Age: Albian). A couple of them came loose during pre-washing and I found another one still in the matrix. Tooth #1: Is this tooth from Meristodonoides sp.? The views are from front and back of this tooth. Approximately 2mm long. Tooth #2: Is this also from Meristodonoides sp.? Approximately 3mm long. Tooth #3: Is this from Leptostyrax sp.? Front and back views of this tooth. Approximately 6mm long.

    Fish tooth #2?

    I named this topic as Fish tooth #2? because this fossil is very similar to my another fossil in a previous topic a while ago. Nobody really have any consensus on what it is and I thought it might be a fish tooth. I hope I will be lucky this time to have someone identify it for me with confidence. Located in Ellsworth county, Kansas, age of Albian, and from Kiowa Formation. It's approximately 4mm long. I know identifying specimens from Kiowa Formation can be a real pain since it's so little researched! lol...
