  2. Last weekend Natalie and I went on a city trip to Maastricht in the Netherlands. After a 2h drive and a tour in the city we went to visit the "Natural History Museum of Maastricht" The museum in itself is relatively small , but there are plenty of Maastrichtian fossils on display. Of course the famous mossasaurs and turtle fossils, but also lots of display cases with invertebrates of all kind from the Maastrichtian marls in the area. There are also a lot of volunteers working there to work on recent discoveries and to talk to the visitors about those prepparations .
  3. Late Cretaceous chalk in North America

    Hey everyone I know I've been lately rather inactive on TFF; I was held back by fieldwork and other reasons (though do expect some posts about the fieldwork next weekend ). But anyway, onto what I came to talk about... Would anyone know of some good exposures of Late Cretaceous chalk in Canada or USA? I'm thinking specifically about Campanian chalk or, even better, Maastrichtian chalk.. It would be great if the exposed chalk is very fossiliferous, of course. Thanks for any help! -Christian

  14. Hi, a few days ago I went on my first ever fossil hunting trip to Eben-Emael, a Limestone quarry in Belgium that dates to the Maastrichtian and is part from the type location (the historical ENCI quarry being only a 3,5 km to the north. The trip was orginized by the BVP (Belgische Vereniging voor Paleontologie) and a short report of the trip with phot's and some of the finds can be found in this topic by @Manticocerasman who I was lucky enough to tag along with, cause I doubt I would have found many mention worthy fossils without the guidance of Kevin. But since I am into microfossils I decided to collect some samples of the limestone without the obvious fossils home to later be able to look for microfossils as it should be quite rich. I think I have around 1 - 3 kg of matrix left to look for microfossils. But I have never myself dissolved matrix, and although it seems easy, I don't want to make any mistakes. During the trip they advised me on two different approaches, depending on what kind of fossils I wanted to find. One approach was dissolving in water and the other in vinegar, but now the seeming obvious question. How exactly do I do that? Should I just take a bucket of a glass, fill it halfway with said liquids and just wait? Or should I use a sieve and lay the block there so only fossils remain in the sieve and the rest goes to the buttom. Does the limestone just dissolve or does some kind of putty residu where the microfossils will be in? If so, how to properly remove the fossils when you pour out the liquids without pouring out the fossils? I know I have many questions and some might be very obvious and straigh-forward, but I really haven't done this before and I would like to do it the right way from start. So thanks in advance for any tips & tricks, I would really appreciate any help!
  15. colorful belemnites

    I wanted to share a few belemnites in my collection, personaly I think they are a bit of an underrated fossil and could use a little more attention. They can be very beautiful and colorful and of course they are cephalopods Belemnites from Eben-Emael ( Belgium ) Maastrichtian: Belemnites from the area of Mons ( Belgium ) Maastrichtian: Belemnites of the area of Mons (Belgium ) Campanian (2 brachiopods infiltrated the picture )
  16. 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
  17. NYT article, with video, covers the uncovering of a triceratops skull in North Dakota badlands. Cool side story of one of the discoverers losing chance at internship in So. Cal., La Brea Tar Pits, and gutting out excavation in the badlands. Enjoy. Alice (Triceratops) in Badland

  19. 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)
  20. 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:
  21. 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!
  22. 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
  23. 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 ?
  24. 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.
