Plesiosuchus manselii
(Hulke 1870)

Young et al. 2012 | 1 specimen | ||||||||
NHMUK PV OR40103– incomplete skull (snout and occiput – lacking occipital condyle – with fragments of the supratemporal arches) and isolated right articular. NHMUK PV OR40103a – the right mandibular ramus, some isolated teeth, a humerus, and numerous ribs and vertebrae that are partially or completely imbedded in matrix. Two further specimens may belong to the P. manselii holotype: NHMUK PV OR40104– an occipital condyle, and NHMUK PV OR40105– carpal and tarsal bones. Both specimens were donated to the University of Toronto through Professor Ramsay Wright in 1900. From examining the relevant register in the NHMUK Earth Sciences Department, it is possible both specimens were part of NHMUK PV OR40103 (as they are all part of the same acquisition, NHMUK PV OR40103 lacks the occipital condyle and NHMUK PV OR40103a does not include carpal or tarsal bones). Unfortunately, as neither specimen could be located at the Royal Ontario Museum (K. Seymour, 2011 pers. com.) it is impossible to assess whether they too belong to the holotype | ||||||||||

Because NHMUK 39362 has been traditionally assigned to P. macromerus (Lydekker, 1889a; Tarlo, 1959b, 1960) and that it possesses important diagnostic features, NHMUK 39362 is here recommended to serve as the neotype of P. macromerus (a request to the International Commission on Zoological Nomenclature is in preparation). NHMUK 39362 has previously been assigned to P. grandis (Owen, 1869), but Lydekker (1889a) indicated that there is no evidence that the syntypes of this taxon even belong to Pliosaurus. Further, there exists no overlapping material between these syntypes and NHMUK 39362 (Tarlo, 1960). | ||||||||||

Stratigraphy comments: Outcrops of the Kimmeridge Clay formation are only Kimmeridgian age in Kimmeridge Bay itself.
"According to Morgans-Bell et al. (2001) and Gallois (2000), this area exposes the Aulacostephanus autissidorensis and Pectinatites elegans ammonite zones of the formation" (Knutsen 2012, p. 269) |
