Koutalisaurus
A spoon-jawed hadrosaurid from Late Cretaceous Spain.
Koutalisaurus is a potentially dubious genus of lambeosaurine hadrosaurid dinosaur from the Late Cretaceous of Spain. Its name means 'spoon lizard', referring to the shape of its dentary. The genus is based on a mostly complete dentary recovered from the Tremp Formation near Abella de la Conca, Lleida.

Facts from the source article.
Did You Know?
- The dentary is very elongate with a long toothless portion bent steeply downward and inward, giving the jaw a spoon-like shape when complete.
- The dentary is comparable in size but on the small side and with unusual proportions compared to other hadrosaurid dentaries.
- A 2020 study by Nick Longrich and colleagues found Koutalisaurus to be an arenysaurin.
Discovery and naming
The holotype dentary, IPS SRA 27, was originally referred to Pararhabdodon in 1999, but it comes from a different locality and is based on non-comparable material with unusual characteristics. Prieto-Marquez et al. (2006) placed the dentary in the new species Koutalisaurus kohleorum. Koutalisaurus was later considered an invalid nomen dubium, though subsequent studies have not reflected this and still treat it as valid. A 2007 poster suggested many hadrosaur specimens from the Basturs Poble bonebed might belong to Koutalisaurus, but this was rejected after those remains were reclassified as lambeosaurines such as Adynomosaurus and cf. Pararhabdodon.
