  1. Maastrichtian fieldtrip in Belgium

    Today @Natalie81 and I went on a field trip with our geology club to the quarry of Eben-Emael In Belgium. We were over 50 participants today an I had the oportunity to meet aan other TFF member @ziggycardon This location is not far from the stratotype in Maastricht in the Netherlands and a multitude of fossils can be found in the marls and chalks. We had a slow start, but after searching through scree piles I found a small and a big sea urchin, and later on a few belemnites. Natalie hadn't got much luck at the start of the prospection, but she did eventually find the find of the day: a fragment of a turtle shell ( Allopleuron hofmanni ) with a few verts in association. We did have a great day and Ziggycardon had also his bag full of fossils and a great first fossil fieldtrip. the quarry: Maastrichtian marl ( formation of Emael ) Ziggy in action Natalie's turtle fragment: Home with the finds: A quick cleanup of the big sea urchin: Hemipneustes stratoradiatus

  4. Hi, Some weeks ago, I found those spatangoid echinoids in my usual Upper campanian/Lower Maastrichtian hunting zone of SE of Pyrenees: I think they fit well with Diplodetus brevistella, as shown in http://www.echinologia.com/galeries/micrasteridae/index.html#diplodetus But, I found no other references of Diplodetus in the Pyrenees, and hardly in distant zones of Spain, which makes me doubt (Diplodetus is a genus mostly found in Northern Europe)
  5. Aristotle's lantern ?

    Hi, I found this crushed echinoid in an Upper Campanian/Lower Maastrichtian stage of the Pyrenees. "Not much of a piece", I tought (likely a Micropsis or a Phymosomatoid). But I wonder if this can be its crushed Aristotle's lantern: Close-up: The other side:
  6. Hi everyone! After the recommendations of @Manticocerasman, @gigantoraptor & @Joeri_R I joined the BVP (Belgian Association for Paleontology). Today I got my confirmation mail of the membership. I have long been wanting to go out on fossil hunts especially in my own region which consist of cretaceous limestone from the Maastrichtian. Luckily for me the next fossil excursion planned by the BVP is a trip to the Romontbos quarry in Eben-Emael which is only a 20 - 25 minute drive for me. So I did sign up for said excursion but since it's my first ever fossil hunt I want to go prepared and I was wondering if any of you have any tips on what tools and stuff to take with me to the quarry and what tools are best for excavating said limestone. I already know that a safety helmet, safety gloves and a fluorescent jacket are required and that safety glasses and steeltipped working shoes are recommended. I was also planning on taking enough water to stay hydrated, a backpack and a good strong bag to transport excavated fossils and perhaps some matrix to examine later. And I was planning on purchasing this kit from my regular fossil shop. Are there any other tools or items that I should bring? Or does anyone have some tips for an inexperienced beginner? Or is anyone is familiar with the location feel free to share. Thank you in advance and I look forward to my first hunt!
  7. Hey everyone - It's Christian. For the past few months, I was inactive on TFF as I had a lot of schoolwork.. But now, I've got a lot more time on my hands - which means that I can get back to all things fossil related This of course includes making preparations for my 3rd Møns Klint Fossil Excavation (MKFE - the fieldwork aspect of my Møns Klint Fossil Research Program). I'll be going for 2 weeks, in mid-August - I'm really excited! As I said in a post from a few months ago, the collection policy of this MKFE is essentially the same as last time's (cephalopod, crustacean, echinoderm and vertebrate material). This time, though, there'll be a bigger focus on articulated and/or associated material - eroded sea urchin spines and belemnite fragments are getting too numerous... On the first days of the field trip, I'll have to do quite a bit of prospecting for new sites to work at, because there's a chance that the landslide spoil heap from last year has most likely been washed away by the waves. I'm already having some ideas of particular projects for this field trip, which include a comprehensive collection of washout microfossils - to determine relative abundances of various faunal groups. Another project is the in-depth analysis of fossil material from different layers of chalk - which I hope will yield some zone fossils. Of course, I'm still hoping to find a lil' mosasaur tooth I'll also use this field trip as an opportunity to donate to the GeoCenter Møns Klint some of the fossils I found during the 2nd MKFE. I'll keep you guys posted! Stay tuned I'm so excited to getting back there! -Christian
  8. hoffmanni tooth or beaugei tooth ?

    I bought this tooth as Mosasaurus hoffmanni on internet site. Size: 2,32 inch Location: Oued Zem, Morocco Formation: Ouled Abdoun Basin (Phosphate beds) Is it really hoffmanni ? or beaugei ?
  9. Does anyone have a copy of the following paper: Ricardo C.Ely & Judd A.Case (2019) Phylogeny of a New Gigantic Paravian (Theropoda; Coelurosauria; Maniraptora) from the Upper Cretaceous of James Ross Island, Antarctica. Cretaceous Research (advance online publication)doi: https://doi.org/10.1016/j.cretres.2019.04.003Â https://www.sciencedirect.com/science/article/pii/S0195667118300120 Imperobator is quite notable as the first Gondwanan non-avialan paravian to be named from Antarctica.
  10. This weekend we had a quick stop near the city of Mons in the south of Belgium. It is not commonly known that in some forrests in this area are ancient quarries of Maastrichtian phosphatic chalk, not all are accessible but with a reasearch on old maps some of them can be found with a little effort you can clear out a spot on the ground and search for a multitude of small fossils. we only stayed 2 hours, but we did find our fair share of tiny but beautiful brachiopods, bryozoans, shark teeth, dentaliums, bellemnite fragments,... . @Tidgy's Dad , you'll like those little critters and even a few teeth and an echinoid spine:

  14. Plans for the 3rd Møns Klint Fossil Excavation

    Nowadays, I'm mostly focused on preparing for my high school finals. But in my free time... Well I started to plan the 3rd Møns Klint Fossil Excavation (MKFE), as part of the larger Møns Klint Fossil Research Program. This field session has been planned for mid-August, and will last about 2 weeks - needless to say, I'm pretty excited Especially when considering the success of the 2nd MKFE... Collection policy will remain mostly the same as last time, meaning that arthropod, cephalopod, echinoderm and vertebrate material will be the priority. Of course, there will be a slight change; with more focus on articulated/associated remains (because single, eroded fragments are becoming a bit too numerous...). Also, last year, when I was collecting anything significant (e.g. articulated echinoderm remains), I forgot to try and find associated zone fossils. This time, I'll remember to collect zone fossils (brachiopods and belemnites), as they can be pretty useful for determining more precisely the age of a specimen. Of course, I'll use this field trip as an opportunity to donate to the GeoCenter museum some of the fossils from the 2nd MKFE. Can't wait to go back there!! -Christian
  15. Yesterday I made a visit to the Natural History Museum of Maastricht (The Netherlands) for my Birthday The museum is only a 40 minute drive from where I live and it showcases the entire natural history of the region, the cool thing about this museum is that the fossils which are showcased here are all regional fossils from The Netherlands, Germany & Belgium. I am starting the topic off with 2 pictures of the special exhibit called Microsculptures, which shows giant detailed photographs of insects to show how magnifecent they are. Then I went on to the "Mosaleum" which holds "Bér" the holotype specimen of Prognathodon saturator
  16. Beekite rings

    Last January 12, I found some Exogyra sp. oysters in a limestone Late Campanian / Early Maastrichtian strata (SE Pyrenees, Catalonia, Spain), who turned to show abundant beekite rings. I owe to @abyssunder my knowledge of this mineral phenomenon, which, in my area,occurs mainly over laminar-type shells like oysters' (It can occur on other fossils, though). Have you fossils with beekite rings ?

  19. Hi everyone. I would expose a paleontological ID question that intrigues me. Let me do it in a storytelling style. Prologue Last November I found this beautiful bug in a limestone Upper Campanian /Lower Maastrichtian strata in the SE of Pyrenees, Catalonia (Spain). So, I start a little detective process... which turned not to be so little. This cidaroid specimen is almost complete, retaining even its plates, which is rather rare. In fact, its plates are of most importance in this story. Chapter 1 In 1933 French paleontologist Jules Lambert found some cidaroid specimens in the Pyrenees, in a place not far from I live, called Falgars (a Holy Mary sanctuary surrounded by meadows and woods, a very nice place). He described the species as Typocidaris falgarsensis, designing a holotype. He donated –among others- the holotype to the Museu Geologic del Seminari de Barcelona (Seminary’s –catholic- of Barcelona Geological Museum). But during the turmoil of revolutionary events of Spanish Civil War the Seminary’s was sacked in 1936 and the holotype was lost. In 1997 paleontologist J.J.Carrasco did a revision of the species and fixed a neotype, a specimen found some 4 km west of Falgars, in strata continuity, near the little village of Sant Julià de Cerdanyola. He reclassified it as Temnocidaris (Stereocidaris) falgarsensis (Lambert 1933). He did it in this paper (in Spanish) (The exact site where the original holotype was found is now forgotten) Sant Julià de Cerdanyola village I went to the MGSB museum, where director Dr. Calzada kindly allowed me to compare my specimen with the neotype, and as far as I know they are the same. ID solved? Not entirely In 1991 North-American paleontologists D.B.Blake and W.J.Zinsmeister described a new genus and new species of cidaroid echinoid from the Maastrichtian of Seymour Island, Antarctic Peninsula: Almucidaris durhami. As they said here The species is unique in that the plates of the female expanded and hollowed to form marsupia. Maybe not so unique, though, as during the last 90’s (I don’t know when exactly) some specimens of cidaroid echinoids forming marsupia were found around... Sant Julià de Cerdanyola. You can see them in this thread of the Spanish Foro Nautilus (my specimen is the last one, and was found some 15 km. west of Sant Julià, not far from the town of Berga. Note that it has no marsupia, so it is arguably male). Andrew B. Smith took the view that Pyrenean Upper Cretaceous cidaroids showing marsupia should be classed in the genus Almucidaris, as he stated in The Echinoid Directory. In fact A.B.Smith made for the first time this statement in: Smith, A.B. & Jeffery, C.H. 2000. Maastrichtian and Palaeocene echinoids: a key to world faunas. Special Papers in Palaentology 63, 1-406. Unfortunately, I have no access to this paper. I have sent some messages to TED, with no answer. Unsolved enigmas So, we Spanish amateur or professional paleontologists have assumed Andrew B. Smith’s view, calling our specimens Almucidaris falgarsensis. But some questions remain unresolved. a) If specimens with marsupia are females, what about the male ones (as mine)? The belonging of arguably male specimens of Temnocidaris (Stereocidaris) falgarsensis to the genus Almucidaris can’t be stated? This would lead to a very paradoxical situation, with females of one species belonging to a genus and male ones remaining in another (a bizarre sort of sexual discrimination ). b- Are Almucidaris durhami and Almucidaris falgarsensis the same species or only belong to the same genus? c) Have been found specimens in other places, apart from Antarctica and Pyrenees, of cidaroid echinoids having developed large brood chambers in the plates? I highly appreciate any information and suggestions, and I hope I have not bored you.
  20. Cretaceous turtle, Oued Zem

    Hey everyone I ordered this piece last night, it will probably arrive in the course of this week. According to the listing it is a turtle bone from the cretaceous phosphate layers of Oued Zem in Morocco, but the exact species wasn't identified. But unfortunatly I am not very familiar with Cretaceous sea turles from Morocco, I just found it a nice piece to add to my Oued Zem display. So does anyone know which turtle species can be found in the cretaceous phosphate layers of Oued Zem? The only species that came out while googling was Lytoloma elegans, but I am sure some of you might know other species that lived in Oued Zem during the Cretaceous? Thanks in advance!
