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 ?

Hi, today i went to my favourite trilobite site in my favourite mountains. When i arrived that morning, i discovered under my feet a nice white sea of clouds, making the peaks looking like islands on a sugar sea. The weather was bright and hot Fossils were at the rendez-vous : corals and brachiopods, but also, for the first time, pyrite : And, of course, trilobites

Dear TFF-members, Can anyone help me identify the fossils in the photographs below? I have trouble identifying the concentric patterns that are visible on these (apparently hollow?) shell-like fragments. They were found in the Pyrenees, Spain. The formation in which they were found is Mesozoic in age, most likely Jurassic. Note these are outcrop photographs, so I cannot make additional images to aid identification, unfortunately. Thanks for any feedback you may be able to provide. Kind regards, Tim

Hi, From time to time I found in Upper Campanian strata of SE Pyrenees some big steinkerns looking much like the American "Deer heart clams". So, my initial guesses are genus Cucullaea/Pholadomya/Arca, especially Cucullaea/Pholadomya royana, but my knowledge of bivalves other than rudists is very limited. Can anybody help? @Ludwigia @fifbrindacier Size of the biggest are 92 x 80 x 68 mm Center one is the best preserved (75 x 67 x 53 mm) : is Finally a different, smaller, specimen from same area and strata. I have no

I found those spherical, almost shapeless (or vaguely champignon-like) pieces in an SE Pyrenees Upper Campanian site with rudists, corals, ostreids and brachs. Could They be Siphonia sponges? A broken part of the last one

First described as Terebratella lujani by Luis Mariano Vidal in 1921. In 1984 Dr. Sebastian Calzada revised and created the new genus Ortholina: https://www.researchgate.net/publication/39118241_ORTHOLINA_n_gen_Brachiopoda_Cancellothryridacea_Cretacico_sup_Pirineos The genus was accepted in the Treatise in 2006.

Hi, Recently I found this quite complete (both valves) oyster shell in an Upper Campanian to Lower Maastrichtian strata in SE of Pyrenees. My guess is Amphidonte pyrenaicum, a widespread species in the Tethys at this epoch. Supposing my guess is correct, problem is that I find that species named as (from older to newer papers): Exogyra pyrenaica, Ceratostreon pyrenaicum, Amphidonte pyrenaicum, Amphidonte (Amphidonte) pyrenaicum, and Amphidonte (Amphidonte) pyrenaica. So, I understand that former Exogyra genus has been splitted, Anyone knows of a

Hi everyone. Here are some specimens from an Upper Campanian - Lower Maastrichtian reef in the Catalan Pyrenees, which species’ diversity amazes me. In fact, they are collected in a 30 meter-radius point. I’ve only been able to approximate their genus (thanks to @Pachy, mostly) . So, I’ll strongly appreciate any help. Well, let’s start with the tiniest ones: Heliopora sp. (=Polytremacis), an Octocorallian: Columactinastrea sp.: Synastrea ? (Only my guess)

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)

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:

Hi all, Some weeks ago, I found a site pretty rich in brachipods from the Late Pliensbachian/Early Toarcian in my area (Pedraforca Zone, SE Pyrennes) So, I made a parenthesis in my Upper Cretaceous usual issues, for a change, and I have been picking & preparing them last weeks. This site is very well studied in this paper (in French), and in fossilworks. I probably i found all the species mentioned from the site: Telothyris pyrenaica Telothyris jauberti Q

Hi, I have found this piece in a well-known jurassic site where brachs abound (Late Pliensbachian/early Toarcian, Tenuicostatum biozone, Iberian-Pyrennes basin) My guess is genus Pleuromya. At species level, Pleuromya rotundata is mentioned in the zone, but I find nothing about it (I fear of an invalid or junior species). It looks like Pleuromya uniformis, of whitch @Ludwigia and @nala have posted some pictures.

I found yesterday this -I guess- pieces of crinoid columnals in a Lias (Hettangian) strata. In my area -Pedraforca zone, SE of Pyrenees- Jurassic sites and crinoids are rare (most sites are Upper Cretaceous), so I know very little about them. Tne only crinoid mentioned for the area and period is Pentacrinites. Can you confirm/refute my guess? Thanks.

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
