Koutalisaurus

Koutalisaurus (meaning "spoon lizard", in reference to the shape of the dentary) is a potentially dubious genus of lambeosaurine hadrosaurid dinosaur based on a mostly complete dentary recovered from the Maastrichtian-aged (Late Cretaceous) Tremp Formation near the town of Abella de la Conca, Lleida, Spain.

==Discovery and naming== The holotype dentary, IPS SRA 27, had previously been referred to Pararhabdodon in 1999, but comes from a different locality, is based on non-comparable material, and has unusual characteristics, leading Prieto-Marquez et al. (2006) to place the dentary in the new species Koutalisaurus kohleorum. Koutalisaurus was later found to be an invalid nomen dubium, although later studies do not reflect this hypothesis and still classify Koutalisaurus as a valid genus.
