Ichthyovenator [SEP] Classification
In addition to tooth fossils, a spinosaurid skeleton that possibly belongs to "Siamosaurus" was excavated from the Thai Khok Kruat Formation in 2004 and was identified as a definite spinosaur in a 2008 conference abstract by Angela Milner and colleagues, eight years prior to "Ichthyovenator"s description. In 2012, Allain and colleagues assigned "Ichthyovenator" to the Spinosauridae; more precisely to the subfamily Baryonychinae in a basal position as the sister taxon of a clade formed by "Baryonyx" and "Suchomimus". In Allain's 2014 abstract, he found "Ichthyovenator" instead as belonging to the Spinosaurinae, due to the lack of serrations on its teeth and the similarities of its vertebrae to those of "Sigilmassasaurus".
