Mesozoic Market | Fossil Collector & Amateur Paleontology A fossilized dinosaur tooth of an indeterminate theropod from the Hell Creek Formation in East-Central Montana, USA. This morphology, likely a premaxillary tooth, lacks serrations on the mesial carinae. #FossilFriday #dinosaur #fossil #paleontology #tyrannosaurid #dromaeosaurid #theropod
Mesozoic Market | Fossil Collector & Amateur Paleontology A fossilized dinosaur tooth of a Nanotyrannus sp. from the Hell Creek Formation in Powder River County, Montana, USA. Nanotyrannus is not a true tyrannosaurid but a nanotyrannid eutyrannosaur. #FossilFriday #dinosaur #fossil #paleontology #nanotyrannus #tyrannosaurid #theropod
Mesozoic Market | Fossil Collector & Amateur Paleontology A mosasaur tooth, possibly Tylosaurus rex from the Ozan Formation in Fannin County, Texas, USA. This marine lizard, the T. rex, is the largest known tylosaurine mosasaur and one of the largest species of mosasaur. #FossilFriday #mosasaur #fossil #paleontology #tylosaurus
Mesozoic Market | Fossil Collector & Amateur Paleontology A group of Permian lungfish tooth plates from the Wellington Formation in Waurika, Jefferson County, Oklahoma, USA. I'm not sure what genus these belong to, but they seem closer to the younger aged Ceratodus than to things like Gnathorhiza. #FossilFriday #fish #lungfish #fossil #paleontology
Mesozoic Market | Fossil Collector & Amateur Paleontology A dinosaur tooth of an indeterminate theropod, possibly a coelurosaur from the Kem Kem Group in Morocco. It's hard to say what this tooth belongs to. Megaraptorans are a possibility, as are dromaeosaurids and basal coelurosaurs. #FossilFriday #dinosaur #fossil #paleontology #theropod
Mesozoic Market | Fossil Collector & Amateur Paleontology A worn dinosaur tooth of an indeterminate tyrannosaur, supposedly from the Judith River Formation in Montana, USA. Unfortunately, the provenance for this tooth is absent other than Northern Montana. #FossilFriday #dinosaur #fossil #paleontology #gorgosaurus #daspletosaurus #tyrannosaurid #theropod
Mesozoic Market | Fossil Collector & Amateur Paleontology A dinosaur tooth of a cf. Afrovenator abakensis from the Irhazer Group in Marandet, Aderbissinat, Agadez, Niger. The cookies 'n cream colors can be quite pretty, albeit, the tooth is still fractured like most. #FossilFriday #dinosaur #fossil #paleontology #afrovenator #megalosaurid #theropod
Mesozoic Market | Fossil Collector & Amateur Paleontology A dinosaur tooth of an indeterminate tyrannosaurid from the Judith River Formation in Valley County, Montana, USA. The serrations are oddly weakly developed, though it's unclear what that implies. #FossilFriday #dinosaur #fossil #paleontology #gorgosaurus #daspletosaurus #tyrannosaurid #theropod
Mesozoic Market | Fossil Collector & Amateur Paleontology A fossilized partial placoderm head shield from a Bothriolepis canadensis from the Escuminac Formation in Escuminac Bay, Quebec, Canada. Bothriolepis was a highly prolific Devonian aged genus of armored fish found across the world. #FossilFriday #fish #placoderm #fossil #paleontology #bothriolepis
Mesozoic Market | Fossil Collector & Amateur Paleontology A pair of fragmentary fossilized teeth of a giant beaver or Castoroides dilophidus from Columbia County, Florida, USA. This extinct beaver genus lived alongside American beavers that are still around today. #FossilFriday #synapsid #mammal #fossil #paleontology #castoroides #beaver #rodent
Mesozoic Market | Fossil Collector & Amateur Paleontology Three indeterminate crocodylomorph teeth from the Csehb谩nya Formation in Veszpr茅m County, Hungary. The teeth possibly belong to either cf. Allodaposuchus sp. or cf. Theriosuchus sp. #FossilFriday #crocodylomorph #fossil #paleontology #allodaposuchus #theriosuchus
Mesozoic Market | Fossil Collector & Amateur Paleontology A dinosaur tooth of an indeterminate sauropod, likely a titanosauriform from the Irhazer Group in the Agadez Region of Niger. I'm not entirely sure what it is, but the robust torpedo shaped morphology would suggest a macronarian of some kind. #FossilFriday #dinosaur #fossil #paleontology #sauropod
Mesozoic Market | Fossil Collector & Amateur Paleontology A partial dinosaur tooth of an indeterminate tyrannosaurid from the Two Medicine Formation in Pondera County, Montana, United States. Unfortunately, the mesial carinae is completely worn down. #FossilFriday #dinosaur #fossil #paleontology #gorgosaurus #daspletosaurus #tyrannosaurid #theropod
Mesozoic Market | Fossil Collector & Amateur Paleontology A fossilized lungfish of a Dipterus valenciennesi from the Achanarras Limestone Member, Old Red Sandstone at the Achanarras Quarry in Caithness, Scotland. These basal lungfish are found in various Devonian-aged deposits in Europe. #FossilFriday #fish #lungfish #fossil #paleontology #dipterus
Mesozoic Market | Fossil Collector & Amateur Paleontology A fossilized bird jaw of a Dasornis sp. from Oued Zem, Khouribga, Morocco. Pelagornithids like the Eocene aged Dasornis are known as false-toothed or pseudotooth birds for their serrated beaks. #FossilFriday #dinosaur #bird #fossil #paleontology #dasornis #theropod
Mesozoic Market | Fossil Collector & Amateur Paleontology A fossilized lobe-finned fish of an Osteolepis panderi from the Old Red Sandstone near Skinnet Farm, Hill of Forrs, Thurso, Caithness, Scotland. Osteolepidids are more closely related to tetrapods and lungfish than to ray-finned fish. #FossilFriday #fish #fossil #paleontology #osteolepis
Mesozoic Market | Fossil Collector & Amateur Paleontology A fossilized armored millipede segment of an Arthropleura sp. from the Orzeskie Beds, Upper Silesia Coal Basin, Poland. These giant Carboniferous aged myriapods grew over two meters. The fern genus Zeilleria can also be seen on the slab. #FossilFriday #myriapod #fossil #paleontology #arthropleura
Mesozoic Market | Fossil Collector & Amateur Paleontology A dinosaur tooth of an indeterminate saurornitholestine dromaeosaurid, possibly Saurornitholestes langstoni or Bambiraptor feinbergi from the Judith River Formation in Fergus County, Montana, USA. #FossilFriday #dinosaur #fossil #paleontology #saurornitholestes #bambiraptor #dromaeosaurid #theropod
Mesozoic Market | Fossil Collector & Amateur Paleontology A mosasaur tooth of an indeterminate prognathodontin, possibly cf. Thalassotitan sp. from the Peedee Formation in Holden Beach, North Carolina, USA. This robust tooth morph is comparable to Thalassotitan atrox from Morocco. #FossilFriday #mosasaur #fossil #paleontology #thalassotitan #prognathodon
Mesozoic Market | Fossil Collector & Amateur Paleontology A fossilized crocodylomorph tooth of an Doratodon carcharidens from the Csehb谩nya Formation in Veszpr茅m County, Hungary. This Cretaceous aged terrestrial ziphosuchian croc had serrated teeth similar to those of theropod dinosaurs. #FossilFriday #crocodylomorph #fossil #paleontology #doratodon
Mesozoic Market | Fossil Collector & Amateur Paleontology A dinosaur footprint of the ichnotaxon Eubrontes giganteus from the East Berlin Formation in Connecticut, USA. This Jurassic aged ichnogenus is possibly from Dilophosaurus or a similar species. #FossilFriday #dinosaur #fossil #ichnology #paleontology #eubrontes #gigandipus #dilophosaurus #theropod
Mesozoic Market | Fossil Collector & Amateur Paleontology A fossilized crocodylomorph tooth of an Iharkutosuchus makadii from the Csehb谩nya Formation in Veszpr茅m County, Hungary. Unlike the leaf-shaped teeth of herbivorous crocs like Simosuchus, this genus evolved mammal-like dentition. #FossilFriday #crocodylomorph #fossil #paleontology #iharkutosuchus
Mesozoic Market | Fossil Collector & Amateur Paleontology A rooted dinosaur tooth of a Nanotyrannus sp. from the Hell Creek Formation in Carter County, Montana, USA. This unserrated basal morphology was previously known as the tooth taxon, Aublysodon amplus. #FossilFriday #dinosaur #fossil #paleontology #aublysodon #nanotyrannus #tyrannosaurid #theropod
Mesozoic Market | Fossil Collector & Amateur Paleontology A dinosaur tooth of a Nanotyrannus sp. from the Hell Creek Formation in Carter County, Montana, USA.
