  5. Jurassic Fall Trip

    Last Saturday I was invited to a collecting trip by a buddy of mine. It took us to the Tyrolian part of the Northern calcareous Alps. We worked at a condensed layer that contains a big part of the Jurassic, Hettangian stage(marine ammonoid zones of the Hettangian). Several ammonoid zones are given within this layer. It ranges from the upper Hettangian(the yellow/orange colored top of the layer) down to the grey limestone of the panorbis zone. We were lucky because our gained block from the layer was full of ammonoids. It was kept as it was by my friend. I kept a smaller block which was laterally beside it. The split pic show two big specimen of Psiloceras naumanni
  6. Echinodermata resting place

    Asteriacites lumbricalis are five-rayed trace fossils found in marine sedimentary rocks. They record the burrows of ophiuroid and asteroid sea stars on the sea floor. Here in this particular case it can be assumed that these traces originate from Palaeocoma escheri Herr, 1865 (or Ophioderma escheri), a brittle star, whose remains were found to hundreds in situ in the same layers.
  7. Conifer shoot

    From the album Fossildude's Finds

    Small shoot of the Early Jurassic conifer Brachyphyllum scotti. Hettangian. Newark Supergroup, Hartford Basin, Shuttle Meadow Formation Connnecticut.

  8. Plagiostoma giganteum (Sowerby 1814)

    From the album German Gastropods and Bivalves

    11cm. long. From the lower Jurassic Hettangian Angulatenton Formation, angulaten Zone. Found at a construction site near a small town in Wutachtal township.This species is also alternatively named Plagiostoma gigantea (Boehm 1911). I still haven't figured out which one has priority.
  9. A friend of mine told me last week that they'd started construction on a bypass around a small town in the Wutach area in the fall. They won't be really going at it until the springtime, but he visited the site last week and managed to find a couple of nice Hettangian ammonites on the scree pile, which was free of snow, since the temps are rising at the moment. So, since I was suffering from cabin fever, I figured I'd get out for some fresh air and give it a go. Well, there was lots of evidence of ammonites with a number of large body chamber pieces lying around, but it was obvious after a couple of hours of investigation, also directly at the exposure, that I had arrived quite a bit later than all the local collectors. I did however manage to find a well-preserved Plagiostoma gigantea, or giganteum (depending on which author you prefer) bivalve, which saved the day. I'll have to keep an eye on this site when they start working again anyway. Actually, it was just nice to get out a do some rummaging around.
  10. Finds from today's trip

    Couple Jurassic plants we found today from the shuttle meadow formation. Extra thanks to Tim for the company and expertise. Had a great time splitting rocks and finding stuff.
  11. Coelacanth Scales and Bones

    From the album Fossildude's Finds

    Scales and bones of an Early Jurassic coelacanth, Diplurus longicaudatus. Shuttle Meadow Formation, Hartford Basin, Connecticut. Found on 11/14/2016. This is the rarest fish to find in the Hartford Basin. Even small bits of these are few and very far between.

  16. Misterious shark fin spine from Nothern Italy

    Hello everyone, I'm a student in Milan and I'm currently struggling in trying to identify this fossil shark fin spine. Which taxon do you think it belongs to ? This speciment had been found in Northern Italy. The exact stratigraphic position is yet to be determined, but I can say for sure it's either Upper Rhaetian or Lower Hettangian. The spine is almost 11 inches long (28 cm, 29,2 cm if you count the missing tip) and is yet incomplete, for it lacks the basal structure and there's a big gap at 1/3 of its lenght (see images below). It also shows a pattern of denticles near the tip ( they stop abruptly 10,5 cm from the tip). The internal morphology feature an enlarged cap layer, a thin enameloid layer (lacking in some spots) near the tip while wider near the base and a thin trunk layer. The lumen, the internal cavity, is rain drop shaped and is filled with matrix for more than half of the spine lenght.
  17. Dear all, As of late I have been in discussion with a researcher from the Ammonoid Palaeobiology Lab at the University of Bath in England (https://aplbath.wordpress.com/projects/). The researcher is interested in using Ammonoids/Ammonites from the Norian through to Hettangian for conducting a study. He is specifically interested in using specimens from private collections to augment his research (which delights me, because I am all for amateur-academic collaboration!). I think this would be an excellent opportunity to demonstrate the usefulness of private collections. I am going to donate some specimens for research, and it would be great if other collectors could assist me as I don't have many specimens. YOU DO NOT have to donate the specimens; you can lend them (depending on if they are suitable specimens). If you have any questions, or specimens you are interested in loaning or donating I would love to hear from you and we can discuss it further. I should mention if costs (i.e. shipping) are an issue I assure you we can get around this without you being out of pocket. Please let me know if you have any questions. Best wishes, Joe
  18. New Welsh Dinosaur

    Hi Here's a selection of news links to the new Welsh Dinosaur that was found by Nick Hanigan and Rob Hanigan in South Wales, UK There are lots of stories out there. We made all the UK newspapers yesterday, we were trending on Twitter and the BBC website in the top stories. We made most news bulletins throughout the day and appeared on a number of radio and TV shows. The story seems to be slowly filtering overseas as we've had reports from Europe and the US.

  19. Jurassic Sidestep

    I must admit that I like Triassic ammonoids more but Jurassic ammonites are very interesting too. So two friends and I went on a Jurassic field trip last Saturday. One friend is a specialist of lower Jurassic (Hettangian) Alpine ammonites. We visited two old locations which were unknown to both friends. Weather was very fine. It was one of these golden mountain days in autumn, with warm sun, the smell of fresh fallen leaves and virgin snow on the higher tops. While hiking from one location to the other I was lucky and found a Jurassic/Toarcian Lytoceras sp. The upper side was pretty dissolved due to strong condensation of the limestone I will prep it from the downside which is normally better preserved. The rest of the day we spent at a Hettangian location where we found smaller ammonites which were covered with a black ferro-manganese crust. Andreas
  20. Semionotus tenuiceps

    From the album Fossildude's Finds

    Front half of the early Neopterygian fish Semionotus tenuiceps from the early Jurassic (Hettangian)Shuttle Meadow Formation of Connecticut. This fish needs some prep, but appears to have the entire skull present. This is identified as an S. tenuiceps by the large "hump" directly behind the skull. I believe this is the only identifiable example of this fish in my collection.

  22. Have We Found A Lower Jurassic Dinosaur?

    Hi Me and my brother are hoping that we've found a dinosaur. It was found in Lower Jurassic marine deposits in the UK. The age of the deposits are Hettangian and we think it's from the Psiloceras Planorbis zone, which is almost at the base of the Jurassic. I've posted a thread on the UK Fossil Forum here: http://www.discussfossils.com/forum_posts.asp?TID=5455&title=lavernock-point-dinosaur The important picture so far is this one: It shows what I think is a line of tail verts, with some neurals broken of and some still buried under the matrix. At first I thought they might be plesiosaur phlanages but they were with some long bones that looked like land animal bones. I think the large flat bone that I have partly uncovered is the animal's pelvis. To give you an idea of scale, the verts are about an inch long. Land animals in this deposit are virtually unheard of. My hope is that it is a dinosaur, but a crocodile is another possibility. Again crocodiles from these deposits are unheard of, so that'd be great as well. If anyone has any thoughts then I'd really like to hear from them. I've spent most of the week on the internet researching this as I have virtually no knowledge of dinosaur anatomy. What I have found out is that if it is an animal, especially a dinosaur, then it is extremely rare. Thanks Nick
  23. Large Redfieldius from Shuttle Meadow Formation.

    From the album Fossildude's Finds

    Redfieldius gracilis from the Early Jurassic Shuttle Meadow Fm. Connecticut. Found on 11/10/2013. This bad boy would have measured in at close to 12 inches if complete,... very large for this species.
