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, i've found plant fossils on a Carboniferous site in the Aspe valley, near Etsaut. I thought those could be sigillariae. What do you think ? Item 1 Item 2 Item 3 Item 4, here i think i have some calamites, my question is more about what is seen at the upper left corner, calamites too ?

Hi, today i went back were i found my first trilobites but this time my husband and i went a little further on the way. It's a mythic col in the history of the cycle race Tour de France, a hard pass to reach and the cycles amateurs love to climb it. They were numerous to do so, the sun was shining and hot, it is summer and as childs are on holidays there was a lot of families. So, we arrived there early to have the most time possible alone. For that we woke up at five o'clock, started at six and were up there at about eight. There, among some lovely flowers,

Hi everybody. This year i decided to try new sites to find trilobites. I firstly decided to try a site in the Pyrénées, maybe those who love cyclism and the Tour de France will have heard about the Col d'Aspin and Col du Tourmalet. At the Col d'Aspin, altitude 1489 meters, the landscape is fantastic, green with great trees. The landscape is fantastic, but the trilos didn't show up. Maybe the next time will i be more successful. The only fossil i found is that tiny item, less than a centimeter at the widest. So we decided to head up here, at the observatory of the Pic du Midi de Bigorre : At the foot of that Pic lies the ski station of La Mongie and, above the station, the Col du Tourmalet. There was no fossil to find here, only little cristallizations And an unexpected herd of Llamas The point of view is great

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 guess about it:

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

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 paper about this issue? Thanks

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 Quadratirhynchia vasconcellosi Soaresirhynchia sp. Soaresirhynchia (Alméras, 1994) (former Stolmorhynchia) is a genus of little brachiopods first described by Alméras in a study about Portugueses Toarcian specimens, but are common in all the Iberian-Pyrenean Toarcian basin, from Portugal to South France. Unfortunately, they show great morphology diversity, and I must confess the I am not be able to distinguish one specie from another (S.bouchardi, S.flamandi, S.rustica). Maybe @ricardo could help. These are some examples: Homoeorhynchia batalleri And finally, the only Liospireferina falloti I found, though in poor condition:

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 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.
