Anomotodon Posted April 8, 2019 Share Posted April 8, 2019 Here is another piece of my dinosaur collection - this time material from Eurasian countries. Unfortunately don't have any Triassic or Early Jurassic material, so let's begin with Middle Jurassic (Bathonian) of Itat formation, Krasnoyarskyi region, Russia. Theropods are the most common dinosaurs from there, yet their teeth rarely exceed 15 mm in length. Here is my largest one - could be from Kileskus aristotocus, an early Proceratosaurid (ancestor of Cretaceous tyrannosaurs) and the only described dinosaur from this location. Here are a bunch of Kileskus teeth I had before There also likely were more theropod species, similar to contemporary Chinese Dashanpu formation - methriacanthosaurids (equivalent to Sinraptor), megalosaurids and ceratosaurs. Some teeth I have or had that could be megalosaurids due to bulkier shape and finer serrations (all around 1 cm). In addition I have some specimens from diverse herbivores - Stegosaurids Long-necked sauropods (Mamenchisauridae), possible embryonic teeth Heterodontosaurid fang tooth, 5 mm (huge for this species!) 11 The Tooth Fairy Link to comment Share on other sites More sharing options...
Anomotodon Posted April 9, 2019 Author Share Posted April 9, 2019 Then comes Late Jurassic. Have a Stegosaurid tooth from Kimmeridge clay of Oxfordshire, UK - Dacentrurus armatus. (one of my rarest teeth!) A sauropod vertebra, could be Duriatitan humerocristatus Similar faunal composition can be found in Morrison formation (USA), Tendaguru beds (Tanzania) and Portuguese Lourinha and Alcobaca formations. A theropod from Lourinha, likely Piatnyzkisauridae indet. A Turiasaur tooth, likely cf. Zby atlanticus A sauropod vert from Lourinha France also has some deposits near Late Jurassic-Early Cretaceous boundary, here is a Theropod tooth, possible basal Spinosaurid (tooth has very fine serrations and some enamel flutting - almost ribs like in Spinosaurus) 9 The Tooth Fairy Link to comment Share on other sites More sharing options...
Anomotodon Posted April 9, 2019 Author Share Posted April 9, 2019 Early Cretaceous is well represented in Europe, especially UK. First, there is 140 mya Valanginian Wadhurst clay in Sussex, contrary to the popular opinion, species like Baryonyx or Neovenator cannot be found there, because the deposits there are older than in Isle of Wight. Here is a tiny 7 mm ?Spinosaurid tooth (Suchosaurus cultridens is the only one described) A few microteeth (<5 mm) some of which may or may not be Theropod 8 mm Iguanodont spitter, maybe Hypselospinus Smaller 5 mm ornithopod tooth, cf. Valdosaurus canaliculatus Next come deposits from Isle of Wight - Wessex formation. These teeth are Barremian in age, 130 mya, I have two theropod teeth - cf. Neovenator salerii and ?Megalosauridae indet. No Baryonyx teeth yet unfortunately. The last tooth is very interesting because it has mesial serrations preserved - mesial carina ends half-way and distal serrations are around 4/mm, typical for Megalosauroids 10 The Tooth Fairy Link to comment Share on other sites More sharing options...
fossilsonwheels Posted April 9, 2019 Share Posted April 9, 2019 I do not know much about European Dinos but these are awesome fossils Tim ! Great coolection Link to comment Share on other sites More sharing options...
Anomotodon Posted April 9, 2019 Author Share Posted April 9, 2019 And now we go back to Asia again - Barremian deposits can also be found in Sao Khua formation in Thailand. I have a small Siamosaurus suteethorni spinosaur tooth. Aptian (115 mya) deposits are known in Siberia - Ilek formation. Have a sauropod tooth (cf. Sibirotitan astrosacralis) and an undescribed theropod. 9 The Tooth Fairy Link to comment Share on other sites More sharing options...

Anomotodon Posted April 9, 2019 Author Share Posted April 9, 2019 Thanks everyone! The last group of teeth for now are Late Cretaceous, Turonian (90 mya) of Bissekty formation, Uzbekistan. Most common species from this locality, frequently found on auction sites, is a basal tyrannosaur Timurlengia euotica. Recently sold my only tooth but soon will get a new one that is much better. Possible Dromaeosaurid tooth (25 mm), Itemirus medullaris is described from Uzbekistan. Serrations are poorly preserved unfortunately, but looks like there is a mesial twist to the carina. Now is the most exciting part. Recently acquired some herbivore material, first the undescribed Therizinosaurid. I have a foot claw and a tooth (8 mm). Also a Titanosaurid sauropod tooth (25 mm) A hadrosaur spitter, cf. Levnesovia 7 The Tooth Fairy Link to comment Share on other sites More sharing options...
Runner64 Posted April 9, 2019 Share Posted April 9, 2019 Never seen any herbivore teeth from the Bissekty formation so the sauropod and therizinosaur teeth are super cool! Link to comment Share on other sites More sharing options...

-Andy- Posted April 10, 2019 Share Posted April 10, 2019 Amazingly rare teeth, all of which you won't see in most collector's homes. Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday! Link to comment Share on other sites More sharing options...
