Uktenadactylus wadleighi ( Lee, 1994)

Holotype: SMU 73058 , an anterior portion of the rostrum displaying the alveoli from the 1st to the 8th pair of teeth ( Fig. 4 ).

Type locality: Tarrant County, Texas, USA.

Type horizon: Paw Paw Formation (Albian).

Material.— Holotype only.

Emended diagnosis.— Uktenadactylus species with slightly convex anterodorsal margins of the deltoid facet; a deep and oval (higher than wide) depression above the first tooth pair; a sharp palatal bulbous projection; and second pair of upper alveoli not as lateralised as in U. rodriguesae .

Remarks.—As noted above, Lee (1994) considered this specimen as representing a new species of the genus Coloborhynchus . “ Coloborhynchys ” wadleighi was reassigned to the newly erected genus Uktenadactylus by Rodrigues and Kellner (2008), whose updated generic attribution was also recently considered by other workers ( Witton 2013; Bantim et al. 2014; Jacobs et al. 2019, 2020). For further details see the diagnosis and remarks for the genus.

Stratigraphic and geographic range.— Type locality and horizon only.
