The new taxon is based on composite skull and mandible including premaxilla, maxilla, jugal, quadrate, braincases, predentary, dentaries, surangular, and maxillary and dentary teeth. It is diagnostic by such characters as, sagittal crest extending along entire dorsal surface of the parietal and reaching the frontoparietal suture (autapomorphy), transversely straight frontoparietal suture, caudodorsally faced supraoccipital, no participation of the supraoccipital in the foramen magnum, mesiodistally wide leaf-shaped dentary tooth with primary and secondary ridges on the lingual surface of the crown, perpendicularly-erected and large coronoid process of dentary, and nonvisible antorbital fossa of the maxilla in lateral view. Phylogenetic analysis revealed <i>S</i>. <i>khoratensis</i> as among the most basal hadrosauroids. <i>Sirindhorna khoratensis</i> is the best-preserved iguanodontian ornithopod in Southeast Asia and sheds new light to resolve the evolution of basal hadrosauriforms.</p></div>", "links"=>[], "tags"=>["Sirindhorna khoratensis gen", "Nakhon Ratchasima Province", "maxilla", "dentary", "nonvisible antorbital fossa", "basal hadrosauroid dinosaur", "New Basal Hadrosauroid Dinosaur", "Cretaceous Khok Kruat Formation", "surface", "frontoparietal suture", "supraoccipital"], "article_id"=>1630289, "categories"=>["Biological Sciences"], "users"=>["Masateru Shibata", "Pratueng Jintasakul", "Yoichi Azuma", "Hai-Lu You"], "doi"=>"https://dx.doi.org/10.1371/journal.pone.0145904", "stats"=>{"downloads"=>7, "page_views"=>1, "likes"=>0}, "figshare_url"=>"https://figshare.com/articles/_A_New_Basal_Hadrosauroid_Dinosaur_from_the_Lower_Cretaceous_Khok_Kruat_Formation_in_Nakhon_Ratchasima_Province_Northeastern_Thailand_/1630289", "title"=>"A New Basal Hadrosauroid Dinosaur from the Lower Cretaceous Khok Kruat Formation in Nakhon Ratchasima Province, Northeastern Thailand", "pos_in_sequence"=>0, "defined_type"=>3, "published_date"=>"2016-01-05 14:53:57"}
