Troodon Posted September 8, 2019 Share Posted September 8, 2019 Here is paper on a topic many Dinosaur collectors may be interested in. Unfortunately its paywalled so I rented it to screen grabbed the info to pass it along. https://onlinelibrary.wiley.com/doi/full/10.1002/spp2.1282 Sauropod teeth from the Middle Jurassic of Madagascar, and the oldest record of Titanosauriformes Gabriele Bindellini, Cristiano Dal Sasso First published: 06 September 2019 https://doi.org/10.1002/spp2.1282 The material comes from the Mahajanga Basin, see map, Sakahara Formation (Isalo IIIb subunit) which is dated to the Bathonian stage of the middle Jurassic. At least three sauropod taxa are known Archaeodontosaurus descouensi, Lapparentosaurus madagascariensis and 'Bothriospondylus madagascariensis' (this taxon name is regared as invalid but still used to indicate a Bathonian non-neosauropod eusauropod from Madagascar). Eight Morphotypes were identified. Morphotype J1 are referred to as non-neosauropod eusauropoda Morphotype J2 are referred to as non-neosauropod eusauropoda Morphotype J3 are referred to as a basal brachiosaurid or at least a titanosauriform. Not possible to refer this as L. madagascariensis but some authors would be in agreement. Morphotype J6 are referred to as a basal brachiosaurid or at least a titanosauriform. Not possible to refer this as L. madagascariensis but some authors would be in agreement. Morphotype J7 are referred to as a basal brachiosaurid or at least a titanosauriform. Not possible to refer this as L. madagascariensis but some authors would be in agreement. Morphotype J4 & J5 are assigned to Archaeodontosaurus descouensi Morphotype J8 can be referred to a basal taxon of Diplodocoidea 9 Link to comment Share on other sites More sharing options...
