'''''Kazaklambia''''' is an [[extinct]] [[genus]] of herbivorous [[lambeosaurine]] [[dinosaur]] known from the [[Late Cretaceous]] [[Dabrazinskaya Svita]] ([[Santonian]] stage) of southern [[Kazakhstan]]. It contains a single species, '''''Kazaklambia convincens'''''.<ref name=Kazaklambia>{{Cite journal | last1 = Bell | first1 = P. R. | last2 = Brink | first2 = K.

''Kazaklambia'' was first described in [[1968 in paleontology|1968]] as a species of ''[[Procheneosaurus]]'' by [[Anatoly Konstantinovich Rozhdestvensky]]: ''Procheneosaurus convincens''. The [[specific name (zoology)|specific name]] refers to the fact that the specimen, the most complete dinosaur fossil ever discovered on Soviet territory, convincingly proved that dinosaurs could be found above the so-called "dinosaur horizon".<ref name=AKR68>{{cite book |last=Rozhdestvensky |first=A.K. |authorlink=Anatoly Konstantinovich Rozhdestvensky |editor=Tatarinov L.P. et al.

Bell]] and [[Kirstin S. Brink]].<ref name=Kazaklambia/>

''Kazaklambia'' is known from a nearly complete [[skeleton]] of a [[juvenile (organism)|juvenile]] missing only the snout, the front of the lower jaws, some dorsal vertebrae and end of the tail, [[holotype]] '''PIN 2230''', found by G.A. Belenkiy in 1961.<ref>G.A. Belen’kiy, “Geological structure of the Tashkent area Chule,” Tashkent Gos.

Bell & Brink suggested that ''Kazaklambia'' is morphologically distinct from other [[Eurasian]] taxa and known juvenile lambeosaurines at a similar [[Ontogeny|ontogenetic stage]] in having a prefrontal process of the postorbital with a thickened dome lateral to the frontal dome, doming of the [[nasal bone|nasal]] above and in front of the [[Orbit (anatomy)|orbit]], and a frontal length/width ratio of less than one.

Bell and Brink (2013) assigned ''Kazaklambia'' to the [[Lambeosaurinae]], in a basal position. [[Morphometrics]] and [[Morphology (biology)|morphological]] information suggest that ''Kazaklambia'' might be closely related to the basal lambeosaurines from Asia ''[[Amurosaurus]]'' and ''[[Tsintaosaurus]]'', which was seen as proving an Asian origin of the Lambeosaurinae.<ref name=Kazaklambia/>
