Aspect of the humerus morphology, shape of the deltopectoral crest and ratios of the wing elements suggest that T. regalis is an azhdarchid rather than pteranodontian pterosaur, as originally proposed. A high abundance of azhdarchid remains in the open marine setting of the Moroccan phosphates casts doubt on suggestions that Azhdarchidae are largely terrestrial pterosaurs.
