  1. I found this mandible last year, and have been trying to id it. I think it's squirrel, but I'm not sure. Difficult for me, since it's just a partial. If it is squirrel, genus/species ideas would be greatly appreciated. Thank you! Glacial deposits, E Kansas, USA Has no teeth. Missing lower and rear section of mandible.

    Moroccan Mosasaur ID

    hi I recently wanted to find a Tylosaurid tooth from Morocco, but I'm confused about the tooth morphology of this ID. Because I found that some teeth described as Tylosaurid had very distinct protruding prisms (likes figure 3 and 4) on their crown surfaces, while some teeth were indeed relatively smooth (picture 1 and 2). Which one is correct?

    Tiny moroccan shark teeth

    I got these tiny teeth in some bulk Moroccan stuff, I assumed carchihinid but I saw another dealer has similar larger stuff as Physogaleus secundus. My largest tooth is about 3-5mm Any advice or rescources from the wise heads here is appreciated in advance
  4. Hi mosasaurs lovers, I looked around on different american fossils web sites , and I found, is nowhere a description or list about different species of Mosasaurs from Morocco . So I'll try humbly to fix it . Feel free to correct me if you see something wrong. The Moroccan phosphate history began in 1921 , Moroccan phosphate mines operate three layers of phosphates . Level 1 : Ypresian phosphate bed Level 2 : Thanetian phosphate bed Level 3 : Maestrichian phosphate bed Level 4 : Maestrichian grey phosphate at Sidi-Chenan quarry, ben guerir and youssoufia Level 5 : Maestrichian, grey phosphate,white bones: ben guerir and youssoufia level 6: Maestrichian, grey phosphate,white bones: ben guerir and youssoufia Most of the material on a market belong to oued zem and sidi -daoui zone; even though you will find them under Khouribga denomination, nothing comes from Khouribga... Of course, mosasaurs belong to the level 3, and 4 different species are studied by scientists of the French Museum of Natural History in Paris . Today the last record of different mosasaurs species is at list 18 and probably 20. (personal opinion ) Listed like below : †Halisaurus. arambourgi .(Bardet, Pereda Suberbiola, Iarochène, Bouya & Amaghzaz, 2005) †Halisaurus.sp not described yet †Halisaurus walkeri .(Lingham-Solier, 1998) ( i used this name temporarily, until one studie about this mosasaur show-up ) †Prognathodon sp Dollo, 1889 †thalassotitan atrox 2022 ex †Prognathodon anceps ex leiodon anceps slender form massive form perhaps sexual dimorphism ( personal opinion ) †Prognathodon solvayi Dollo, 1889 †Prognathodon hudae kaddumi 2009 †Prognathodon. currii (Christiansen & Bonde, 2002) †Eremiasaurus heterodontus , gen. et sp. nov sp ( AR. H. LeBlanc, M. W. Caldwell, and N. Bardet. 2012) †“Mosasaurus" baugei Arambourg 1954 ( Mosasaurus beaugei Arambourg, 1952 (Squamata, Mosasauridae) from the Late Cretaceous phosphates of Morocco Nathalie Bardet , Xabier Pereda Suberbiola , Mohamed Iarochene , Fatima Bouyahyaoui , Baadi Bouya , Mbarek Amaghzaz . 2004 ) †Mosasaurus hoffmanni Mantell, 1829 †hainosaurus boubker, 2022 slender form long premaxillary like tylosaurus proriger massive form short premaxillary like hainosaurus personal constatation † Stelladens mysteriosus (Nicholas R.

  5. Hello crew. I was wondering if you all might help with identification of this egg. It was given to me as a gift, about 20 years ago. It's from Hong Kong (which makes me immediately suspicious). I checked out the thread on how to identify a fake, but not being an expert, I really can't tell one way or another. Now if it were a 60s Mustang, or a vintage computer, I could for sure tell you all about it! Hoping you brave souls might take a crack (haha) at verifying whether not it's real, and what species it might be if it were. It looks great on my hutch behind my desk regardless, so no need to be gentle. Thank you for your time!

    Paralejurus species?

    I found this trilobite of the Paralejurus genus and now it has been prepared and I would like to know if is possible to know the species. It was found in Ihandar formation, near Alnif. It's a lower devonian formation. The trilobite measures 7cm. I will tag you @piranha as I think you are my best hope.

    Naming nomenclature

    Hi all, A bit of a newbie so apologies if this is a dumb question but was hoping for the naming nomenclature a bit more. I understand that sp. means species (used when the species is unknow, but the genus isn't) and indet. means indetermined. But what does cf. mean? classification? I've seen it used before the genus and also after followed by a person's name. For example, I read on this forum a tooth found in the Bull creek canyon formation belonging to cf Coelophysis. Aswell as ready of a Apachesaurus cf. A gregorii. Are there any other terms that are frequently used?

    Trilobite Species?

    Got this trilobite at a show on the weekend, was wondering if anyone could possibly help me identify the species. (I know there are a lot of trilobite species so I’m not sure if this will even be possible). The place I got it from said they source their fossils from Madagascar, Morocco, and France. Not sure exactly where this guy came from tho. Thanks for any help.
  9. Hi all, I could not resist to get these 3 beautiful hadrosaur eggs. Those have been the last ones in my price range, and from a renowned local seller. Was wondering if anyone could give more insights. Here is what I have Possibly saurolophus 80 mio. year old, Cenomanian, Late Cretaceous Egg size 10.5 to 12cm (4 to 4.5"), about 8-9kg (18lbs) Xixia Basin, Henan province, China From an old collection Hoping no one tells me I bought some fakes .... (well, then I will return them ...). I am so curious. Getting them by tomorrow. Any comments from the experts here? Thanks a lot in advance. mr.rod

  12. Hola, necesito ayuda para poder determinar la especie de este fósil, procede del sur de Marruecos y está encajado en una pieza de 155cmx 113cm, sabemos que petenece a la familia Mosasauridae pero tenemos dudas con respecto al género y si es un adulto o una cría. (Translation added and post moved...) Hello, I would appreciate your help to identify a fossil, it comes from southern Morocco and is embedded in a bed of clay, its measurements are 155cmx113. We've been told it's a Mosasaurus, but we have some doubts about the genus.

    ChatGPT

    I just had a general discussion about Fossils with ChatGPT, It's a language model created for the purpose of holding a conversation with the end user. A search engine indexes web pages on the Internet to help users find the information they need. I have to say I'm impressed it was able to find species level information as well as specific information on geologic formations in my area. Of course, I don't really know how good the information is. As an example, here is a question I ask and the corresponding answers it returned What is the difference between Rafinesquina alternata, and Rafinesquina crenulata ? Rafinesquina alternata and Rafinesquina crenulata are both species of brachiopods, which are a group of marine invertebrates that have a bivalve-like shell. The two species belong to the genus Rafinesquina and are found in the fossil record of the Ordovician period. The main difference between the two species is in the shape and ornamentation of their shells. Rafinesquina alternata has a sub-triangular shape with a convex ventral valve and a concave dorsal valve. The shell is smooth and has a curved hinge line. Rafinesquina crenulata, on the other hand, has a more circular shape with a convex ventral valve and a concave dorsal valve. The shell is ornamented with crenulations or small, rounded ridges along the margin of the valve. Both species lived in the shallow sea environments of the Ordovician period, and are found in the fossil record in North America and Europe. They are important fossils for biostratigraphy and help in dating of the rocks and understanding the faunal change through the time. It's worth noting that species identification of fossils might be difficult and uncertain, as it is based on morphological characteristics, and not all characteristics are preserved in fossils.
  14. Is the dinosaur, or so called dinosaur Deltadromeus Agilis an actual valid species of dinosaur. As some people claim it to be. Others do not. I do not have a clear view of the situation and I'd love someone to properly explain it.
  15. Was hoping someone could tell me what the fossils I found are from and about how old they might be but any information is useful thanks
  16. Is it possible to put forward a proposal to name an unnamed fossil species? Where (organization name) would such a proposal be sent? Thank You, -G
  17. Hi folks! I’m kind of stuck on this one. I presume this is a gastropod and not a cephalopod because of its small size (diameter around 2 cm). But what order, family, genus and species? Its found at Mt Billingen in Sweden, in a layer from middle Ordovician (middle to upper Darriwilian).

    Pecopteris Species ID Help

    I am nearly finished with my review and reevaluation of all of my plant and fern findings from the Late Pennsylvanian Llewellyn Formation of Pennsylvania. I think that I have been fairly successful at identifying everything with their proper genus and species using the guide "Fossil Plants From the Anthracite Coal Fields of Eastern Pennsylvania." My hope is use this information with some nice photographs to put together an album under the Member Collection tab. However, one of the last things I need to review are my Pecopteris (or former Pecopteris) finds. I was wondering if any of the members with greater knowledge in paleobotany (@paleoflor @fiddlehead) might be able to verify my suspicions or offer an identification suggestion. It is possible that the ferns did not preserve enough to make a species identification feasible. Any help is greatly appreciated. Thank you! #1- Pecopteris lepidorachis??? - Pinnulets on lefthand side measure ~7mm; pinnulets on righthand side measure ~1cm #2- Pecopteris lepidorachis??? - Pinnulets measure ~6-8mm #3- Left: Pecopteris lepidorachis??? - Pinnulets measure ~7mm Right: Pecopteris miltoni??? - Pinnulets measure ~1.4cm #4- Pecopteris cistii??? - Pinnulets measure ~5mm #5- Pecopteris miltoni??? - Pinnulets measure ~8-9mm #6- Pecopteris miltoni??? - Pinnulets measure ~1cm #7- Acitheca polymorpha??? - Pinnulets measure ~9mm #8- Pecopteris arborescens??? - Pinnulets measure ~4mm #9- ??? - Pinnulets measure ~6mm #10- Pecopteris miltoni??? - Pinnulets measure ~1.5-2cm #11- Lobatopteris lamuriana??? - Pinnulets measure ~1.3cm #12- Lobatopteris lamuriana??? - Pinnulets measure ~1cm #13- Pecopteris miltoni??? - Pinnulets measure ~7mm
