Burianosaurus is anextinctgenus ofornithopoddinosaur that lived in what is now theCzech Republic (it was found in 2003 near the city ofKutná Hora), being the first validly named dinosaur from that country. The type species,B. augustai, was named in 2017; the genus name honours the CzechpalaeoartistZdeněk Burian, and the species name honours the Czech palaeontologistJosef Augusta.[1] Theholotype specimen is a femur discovered in sediments belonging to thePeruc-Korycany Formation in 2003, which was described as possibly belonging to aniguanodont in 2005.[2]
When the fossil was first described in 2005, it was said to be most morphologically similar to Early Cretaceous members ofIguanodontidae, as opposed to later taxa such asRhabdodon.[2] Madziaet al. (2017), the study which named the genus, ran twophylogenetic analyses to test the relationships of the taxon. The first, based on the matrix of MacDonaldet al. (2012), found it within thecladeRhabdodontomorpha, with support very strong for it being outside ofAnkylopollexia. The analysis based on the Boydet al. (2015) matrix, which they considered more strongly supported, due to better taxon sampling of basal ornithopods andneornithischians, found it to be one of the most basal ornithopods, sister to thecladeIguanodontia.
