'Morturneria' Cabrera, 1941
'Morturneria' is a junior synonym of Aristonectes (Gasparini et al. 2003). The taxon was originally introduced as 'Turneria seymourensis' by Chatterjee and Small (1989) but the genus name was preoccupied and so Chatterjee and Creisler (1994) later revised the name to 'Morturneria seymourensis'. The taxon was based on TTU P 9219, an incomplete skull and mandible plus associated cervical vertebrae.
