Ieldraan melkshamensis was named by Foffa et al. (2018) [Metriorhynchid crocodylomorph with the following unique combination of characters (autapomorphic characters are indicated by an asterisk*): apicobasal parallel flutings on the middle facet of the labial surface*; enlarged tooth crowns; denticulated keeled carinae with microscopic, poorly developed, non-contiguous, non-uniform in size and shape denticles; ornamentation of skull and mandible elements consisting of small pits and shallow fine grooves (shared with Geosaurus); greatly enlarged basioccipital tuberosities*. Additionally, the hypoglossal nerve opening is situated below the level of the ventral rim of the foramen magnum*. This could also be a diagnostic feature, but without CT scans from a well-preserved specimen it is difficult to be sure of the correct location of the hypoglossal nerve opening (see Description).]. Its type specimen is NHMUK PV OR 46797, a partial skull (an incomplete and severely diagenetically damaged skull (including fragments of maxilla, portions of the nasals, frontal, both prefrontals, postorbitals, left s), and it is a 3D body fossil. Its type locality is Melksham, which is in a Callovian open shallow subtidal claystone in the Oxford Clay Formation of the United Kingdom.
