Runner64 Posted December 18, 2019 Author Share Posted December 18, 2019 Two more in my collection I am just now realizing I accidentally left out: Hadrosauroidea indet. (cf. Batyrosaurus rozhdestvenskyi) Cretaceous (Santonian-Campanian) Bostobe Formation Akkurgan (135 km north of Dzhusala railway station), Kzyl-Orda Oblast, Kazakhstan Theropod indet. Cretaceous (Berriasaian) Chamblanc Quarry Cherves Richemont, Cherves-de-Cognac, France 5 Link to comment Share on other sites More sharing options...

Runner64 Posted December 22, 2019 Author Share Posted December 22, 2019 A small update but an update nonetheless: Ceratosauria indet. Jurassic (Bathonian) Isalo IIIb formation Ambondromamy, Madagascar Came to the conclusion using a paper by Maganuco, S., et. al. (citation below). They analyzed theropod teeth from the Isalo IIIb formation and attributed them to 8 morphotypes. Mine would fall under morphotype 2 by having a mesial serration density of 14/3mm and a distal serration density of 11/3 mm. The tooth is also labiolingually compressed. Maganugo, S., Cau, A., Pasini, G. "First description of theropod remains from the Middle Jurassic (Bathonian) of Madagascar". 01/01/2005. 146:165-202. 6 Link to comment Share on other sites More sharing options...

Troodon Posted December 22, 2019 Share Posted December 22, 2019 Always enjoy seeing material from the uncommon localities. Nice additions. Quite a good paper you found it characterizes the teeth quite well and why its necessary to analyze isolated teeth to try to get close to an ID and not just rely on photos 1 Link to comment Share on other sites More sharing options...

This is especially true for theropod and sauropod teeth from the Jurassic (Morrison, Isalo IIIb, Lourinha Formation, etc.). Heck, even most small theropod teeth from the Hell Creek formation require an in-depth analysis as well. Link to comment Share on other sites More sharing options...

Unfortunately to many collectors believe you can ID a theropod tooth based on a couple of photos. Hopefully this forum can change that thinking. 2 Link to comment Share on other sites More sharing options...
Runner64 Posted January 3, 2020 Author Share Posted January 3, 2020 Here is a new tooth from a very odd location and the oldest in my collection: cf. Spinophorosaurus nigerensis (Eusauropoda) Jurassic (Aalenian-Callovian) Irhazer Shale (Irhazer II formation) Agadez Region, Niger Paper used to help analyze this tooth: Remes, Kristian, et al. “A New Basal Sauropod Dinosaur from the Middle Jurassic of Niger and the Early Evolution of Sauropoda.” PLOS ONE, Public Library of Science, journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0006924.

Runner64 Posted January 3, 2020 Author Share Posted January 3, 2020 Just received three rooted hadrosaur teeth from Kazakhstan: Hadrosauroidea indet. (cf. Batyrosaurus rozhdestvenskyi) Cretaceous (Santonian-Campanian) Bostobe Formation Akkurgan (135 km north of Dzhusala railway station), Kzyl-Orda Oblast, Kazakhstan Tooth 1: Tooth 2: Tooth 3: A basic overview of dinosaur teeth from the Bostobe Formation: dyke, Gareth J., and Dmitry V. Malakhov. “Abundance and Taphonomy of Dinosaur Teeth and Other Vertebrate Remains from the Bostobynskaya Formation, North-East Aral Sea Region, Republic of Kazakhstan.” Cretaceous Research, Academic Press, 23 Aug. 2004, www.sciencedirect.com/science/article/pii/S0195667104000631. Unfortunately, am not familiar if any papers have been released talking about these hadrosaur teeth. A maxilla was found with the holotype so no teeth can definitively be attributed to Batyrosaurus rozhdestvenskyi. @Troodon are you familiar? 6 Link to comment Share on other sites More sharing options...

Thanks Frank, a few more papers to add that I have used in the past but did not cite previously. Paper on dinosaur fossils of Eastern USA with an in-depth list of all cataloged dinosaur specimens in institutions: Ebersole, Sandy M., and James L. King. “A Review of Non-Avian Dinosaurs from the Late Cretaceous of Alabama, Mississippi, Georgia, and Tennessee.” Research Gate, 2011, www.researchgate.net/profile/Sandy_Ebersole/publication/319376516_A_Review_of_Non-Avian_Dinosaurs_from_the_Late_Cretaceous_of_Alabama_Mississippi_Georgia_and_Tennessee/links/5b6c3f4545851546c9f930bd/A-Review-of-Non-Avian-Dinosaurs-from-the-Late-Cretaceous-of-Alabama-Mississippi-Georgia-and-Tennessee.pdf. Interestingly the following claim is made: "currently all tyrannosauroid material from this area is now regarded as A. montgomeriensis (D. Schwimmer, pers. comm.)." Paper on theropod teeth of Maevarano Formation: "Theropod tooth assemblages from the Late Cretaceous Maevarano Formation and the possible presence of dromaeosaurids in Madagascar" Looks at theropod morphologies and classifies them in several groups Paper I used to help ID megalosaur teeth in Tiouraren Formation in Niger: Hendrickx, Christophe, et al. “The Dentition of Megalosaurid Theropods.” BioOne Complete, 2013, www.app.pan.pl/archive/published/app60/app000562013.pdf.
