  4. Scapanorhynchus puercoensis teeth

    Here are two teeth from a fairly recently (2011) described Scapanorhynchus species from the Upper Cretaceous Santonian in New Mexico. Scapanorhynchus puercoensis has a dentition similar to S. lewisii and was likely very similar. My son and I do classroom science presentations about fossils and our shark program features Scapanorhynchus. He used the lewisii as the basis for his illustration and now we can actually provide teeth that are a closer match to that than S. texanus likely was. This also allows him to draw S. texanus in a more Sand Tiger like form which we both think it was. I put quite a bit of research in our programs and we strive for accuracy so I am really digging these teeth !!!
  5. 'Moose' the mosasaur

    I had the opportunity and good fortune to participate in the excavation and preparation of a mosasaur this past year. The specimen was discovered by a new friend, Allison, in a small unnamed stream adjacent to family property in east-central Mississippi (? Prairie Bluff Fm, Upper Cretaceous, Late Maastrichtian).Allison found the first bones in early May and contacted me for help in identifying the bones through a mutual friend. I'm far from an expert, but was able to ID the bones (a radius and vertebra) as mosasaur. She was really excited, since the bones were her first vertebrate fossils other than a few Pleistocene horse teeth from the same creek, and promised to continue searching. On her next trip, Allison exposed part of a mosasaur jaw and sent pics to me while still in the creek. Long story - short version -- We (Allison, my grandson, Logan and I) began serious excavation in early June 2018 and continued collecting (several trips) and preparation through November. Dr. Lynn Harell, Paleontologist with the Alabama Geological Survey viewed photos of the specimen as I prepped them and helped to ID individual bones and confirmed the genus as Mosasaurus. Dr. Takehito Ikejiri, Alabama Museum of Natural History, worked with me to compare "Moose' (named by Allison) to many specimens in the archives of the Museum. Both were extremely helpful to me as we tried to confirm the ID and agreed that it should be labeled as Mosasaurus sp. until further study. George Phillips of the Mississippi Museum of Natural Science identified associated invertebrate specimens in hopes of confirming the geology of the site (still unconfirmed). 'Moose' was donated to the Dunn-Seiler Museum at Mississippi State University in December 2018. It will be studied as part of a graduate students research. Following are a large number of photos documenting the site, excavation, prepration, and bones of 'Moose'. Thanks for looking.
  6. Hell Creek crush plate?

    Fossil teeth found in the Hell Creek badlands of southeastern Montana! measures approx .42 inches long Amphibian? They are from uppermost Cretaceous age (Maastrichtian) deposits, in the Hell Creek Formation, Carter County, Montana. Any help identifying would be appreciated.
  7. Hoploscaphites Spedeni

    Originally the specimen was collected as a concretion from upper Pierre Shale Formation near the lowest level of the Fox Hills Formation. The collection location is Cedar Creek about seven miles south of Glendive, Montana. The Date collected was Oct. 12, 2018. Later, I removed most of the concretion/matrix with diamond blade and bits. Two of the hoploscaphites spedeni were badly crushed and fractured during fossilization and are missing half of shells. During prep, I miscalculated the depth of cutting blade, slightly damaging the middle scaphites.
  8. New Cretaceous Pterosaur from Southeastern France

    Just got this report of a new pterosaur (Mistralazhdarcho maggii) from the Upper Cretaceous of southeastern France The specimen was collected from the highly fossiliferous "Velaux-La Bastide Neuve" site (Bouches-du-Rhône region), a site known for diverse tetrapod remains. The remains described consist of a mandibular symphysis, a few vertebrae, and several limb bones (including 2 humeri, a radius, a pteroid, a metacarpal and a wing phalanx). The authors of the paper (see attached below) consider that due to incomplete ossification of the bones, the specimen might represent an immature individual. M. maggii helps to provide more insight into the Late Cretaceous European azhdarchid radiation. Romain Vullo, Géraldine Garcia, Pascal Godefroit, Aude Cincotta & Xavier Valentin (2018): Mistralazhdarcho Maggii, Gen. Et Sp. Nov., A New Azhdarchid Pterosaur from the Upper Cretaceous of Southeastern France, Journal of Vertebrate Paleontology, DOI: 10.1080/02724634.2018.1502670 Abstract: A series of pterosaur bones from the Upper Cretaceous (Campanian) of Velaux (Bouches-du-Rhône, southeastern France) is described. This material, including both cranial and postcranial elements found in close association and likely belonging to a single immature individual, is assigned to a new genus and species of azhdarchid pterosaur, Mistralazhdarcho maggii. This large-sized taxon (wingspan ca. 4.5 m in the holotype, possibly reaching 5–6 m in mature individuals) is characterized by a slightly downturned mandibular symphysis that shows a ‘V’-shaped cross-sectional profile and bears a well-developed, anteriorly located median eminence on its dorsal surface. The presence of a median eminence suggests that Mistralazhdarcho might be closely related to Alanqa from the Cenomanian of Morocco. The material described here represents the first partial skeleton of a pterosaur recovered from the Late Cretaceous deposits of western Europe, and the new taxon is one of the most completely known European azhdarchids. Mistralazhdarcho is intermediate in size between the medium-sized genus Eurazhdarcho and the giant-sized genus Hatzegopteryx, two azhdarchids from the Maastrichtian of Romania. The discovery of Mistralazhdarcho suggests the presence of a third azhdarchid size class in the continental ecosystems of the latest Cretaceous European archipelago. photography of the mandibular symphysis of M. maggii (measures 264mm).

  10. Sponge ?

    Hi, I've found today this tiny but interesting piece in a Campanian-Maastrichtian coral-rudist lithosome in SE Pyrenees. I've found there branched corals and bryozoans, but this one don't seem to me neither coral nor bryozoan. Could it be a sponge ? Thanks
  11. New tyrannosaurid from New Mexico

    Hey everyone There's this new bit of research from PeerJ, describing the partial remains of a new tyrannosaurid, Dynamoterror dynastes (pretty cool name, huh? ). The remains were from the Menefee Formation (Upper Cretaceous) of New Mexico, and are a valuable addition to our knowledge of North American tyrannosaurids. Partial cranial material of D. dynastes. McDonald et al. (2018). A new tyrannosaurid (Dinosauria: Theropoda) from the Upper Cretaceous Menefee Formation of New Mexico. Abstract: The giant tyrannosaurids were the apex predators of western North America and Asia during the close of the Cretaceous Period. Although many tyrannosaurid species are known from numerous skeletons representing multiple growth stages, the early evolution of Tyrannosauridae remains poorly known, with the well-known species temporally restricted to the middle Campanian-latest Maastrichtian (∼77–66 Ma). The recent discovery of a new tyrannosaurid, Lythronax argestes, from the Wahweap Formation of Utah provided new data on early Campanian (∼80 Ma) tyrannosaurids. Nevertheless, the early evolution of Tyrannosauridae is still largely unsampled. We report a new tyrannosaurid represented by an associated skeleton from the lower Campanian Allison Member of the Menefee Formation of New Mexico. Despite fragmentation of much of the axial and appendicular skeleton prior to discovery, the frontals, a metacarpal, and two pedal phalanges are well-preserved. The frontals exhibit an unambiguous autapomorphy and a second potential autapomorphy that distinguish this specimen from all other tyrannosaurids. Therefore, the specimen is made the holotype of the new genus and species Dynamoterror dynastes. A phylogenetic analysis places Dynamoterror dynastes in the tyrannosaurid subclade Tyrannosaurinae. Laser-scanning the frontals and creation of a composite 3-D digital model allows the frontal region of the skull roof of Dynamoterror to be reconstructed. You can download (for free!) the paper from this link: McDonald et al. 2018 Dynamoterror dynastes Hope you like this! -Christian
  12. Fossil identification from Comox valley

    Hi folks, I found these two fragments on the Puntledge River in Courtenay, British Columbia, Canada. These are from shale rock of Upper Cretaceous age. I think the one on the right might be a heteromorph ammonite and but I have no idea on the left one. Perhaps a thick shell? The pieces are about 5cm in length in the photo. I would really appreciate any ideas on what type of fossils these are. Cheers, Martin
  13. Armigatus brevissimus 1.jpg

    From the album MY FOSSIL Collection - Dpaul7

    Armigatus brevissimus Fish Fossil Cenomanian of Hakel, Lebanon Upper Cretaceous Period (100.5-66 Million Years Ago) Armigatus is an extinct genus of clupeomorph fishes belonging to the order Ellimmichthyiformes. These fishes lived in the Upper Cretaceous (Cenomanian / Turonian, about 95-90 million years ago); their fossil remains have been found in the Middle East and North Africa. Armigatus has an osteoglossid-like tooth patch, a large foramen in the anterior ceratohyal and a series of subtriangular dorsal scutes, giving rise to their scientific name. The Latin genus name armigatus, means bearer of armor. Brevissimus signifies "shortest, smallest". Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Subclass: Neopterygii Infraclass: Teleostei Superorder: Clupeomorpha Order: †Ellimmichthyiformes Genus: †Armigatus Species: †brevissimus

  17. Cretaceous corals

    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)
  18. Kummelonautilus?

    While on an adventure with @Pilobolus, exploring the Dakota Sandstone and underlying shales, I found something very exciting*... ...my first coiled Nautiloid! Coiled Nautiloid Upper Cretaceous (Cenomanian) Paguate Member of the Dakota Formation Sandoval County, New Mexico Now, after a bit of research, I write here to lean on this Forum for assistance with identification. I find that this specimen sits well in the genus Kummelonautilus...what say you? Many thanks for your help, -P. *Bryan can attest to my yelling and jumping around. @FossilDAWG
