No full textErketu ellisoni Ksepka and Norell, 2006 HOLOTYPE: Geological Institute of the Mongolian Academy of Sciences (IGM) 100/1803, first six articulated cervical vertebrae, right sternal plate, and articulated right tibia, fibula, astragalus, and calcaneum. REFERRED MATERIAL: IGM 100 /1803, three articulated cervical vertebrae (fig. 1). These elements pertain to the holotype individual and are therefore assigned the same specimen number and considered part of the holotype. Measurements are in table 1. LOCALITY AND AGE: Bor Guvé, Dornogov Aimag, Mongolia. Provisionally referred to the Baynshiree Formation (early Late Cretaceous).Published as part of Ksepka, Daniel T. & Norell, Mark A., 2010, The Illusory Evidence for Asian Brachiosauridae: New Material of Erketu ellisoni and a Phylogenetic Reappraisal of Basal Titanosauriformes, pp. 1-28 in American Museum Novitates 2010 (3700) on page 3, DOI: 10.1206/3700.2, http://zenodo.org/record/535917

The contemporaneous Transylvanian and Haţeg basins are indicated; the Pui locality is just a few kilometers from the town of Haţeg.Published as part of Vremir, Mátyás, Witton, Mark, Naish, Darren, Dyke, Gareth, Brusatte, Stephen L., Norell, Mark & Totoianu, Radu, 2015, A medium-sized robust-necked azhdarchid pterosaur (Pterodactyloidea: Azhdarchidae) from the Maastrichtian of Pui (Haţeg Basin, Transylvania, Romania), pp. 1-16 in American Museum Novitates 2015 (3827) on page 4, DOI: 10.1206/3827.1, http://zenodo.org/record/536804
Psittacosaurus amitabha Napoli & Hunt & Erickson & Norell 2019, sp. nov.
No full textPsittacosaurus amitabha, sp. nov. ETYMOLOGY: The celestial Amitabha Buddha is the Buddha of infinite light, and one of his attributes is extreme longevity (fig. 1). Amitabha is the principal Buddha of Pure Land Buddhism and is highly venerated in Mongolia. HOLOTYPE: IGM 100 /1132, a nearly complete, undistorted skull with an associated partial mandible and fragmentary postcranial elements. The specimen was discovered by M.A. Norell and J.M. Clark. All elements represented in IGM 100 /1132 are listed in appendix 1, and select measurements are given in table 1. TYPE LOCALITY: Ondai Sayr, Ussuk, Tsaagan Nor basin, Central Mongolia (fig. 2). The Ondai Sayr locality has also been considered the Andakhuduk Formation (Jerzykiewicz, 2000). The age of the locality is generally considered to be Barremian (Jerzykiewicz and Russell, 1991). Other dinosaurian remains have been found at this locality, including juvenile specimens of Psittacosaurus (Coombs, 1982), but vertebrate fossils are extremely rare (M.A.N., personal obs.). A list of all American Museum of Natural History specimens from the Ondai Sayr locality is presented in appendix 2.Published as part of Napoli, James G., Hunt, Tyler, Erickson, Gregory M. & Norell, Mark A., 2019, Psittacosaurus amitabha, a New Species of Ceratopsian Dinosaur from the Ondai Sayr Locality, Central Mongolia, pp. 1-36 in American Museum Novitates 2019 (3932) on pages 3-6, DOI: 10.1206/3932.1, http://zenodo.org/record/459871
