Uktenadactylus

Uktenadactylus is a genus of anhanguerid pterodactyloid pterosaurs from the Early Cretaceous Paw Paw Formation of Texas, United States and the Wessex Formation on the Isle of Wight, England. Fossil remains of Uktenadactylus dated back to the Early Cretaceous period (Barremian to Albian stages), from about 125 to 100 million years ago.

==Discovery and naming== In 1994, Yuong Nam-Lee named a new species within the genus Coloborhynchus: Coloborhynchus wadleighi, based on a partial snout found in 1992 in Albian layers in Tarrant County, holotype SMU 73058 (Shuler Museum of Paleontology, Southern Methodist University at Dallas). The specific name honors the collector of the fossil, Chris Wadleigh. The reference of the species to the genus Coloborhynchus was based on the fact that both C. wadleighi and the type species of Coloborhynchus, Coloborhynchus clavirostris, share the trait of having three pairs of teeth laterally placed within a broad snout tip. This would distinguish both from the species Criorhynchus simus and justify a revival of the genus Coloborhynchus that since an analysis by Reginald Walter Hooley in 1914 had generally been considered identical to the genus Criorhynchus or the genus the latter had again been sunk into, Ornithocheirus.
