Description
Paraseraphs cantamessae Maxwell, Rymer & Congdon, 2018
Figure 7C
1974 Paraseraphs cf. armoricensis Cossmann — Jung 1974, p. 37, pl. 11, figs. 1–6.
2018 Paraseraphs cantamessae Maxwell, Rymer & Congdon, p. 37, fig. 1.
Type material. Holotype — USNM 135097 A. The type measures 56.9 mm in length and 11.6 mm in width (Maxwell et al. 2018a).
Type locality. White Limestone Group, Port Antonio, Jamaica [Priabonian].
Diagnosis. The shell is very slender with slightly concave whorls. There is a distinctive elongation of the shell on later whorls. The base of the shell is anteriorly quadrate. The shell spire is acute.
Distribution. EOCENE—Priabonian— Jamaica Port Antonio (Jung 1974).
Remarks. Paraseraphs cantamessae is comprised of eight specimens, which are internal casts. The shape of P.
cantamessae is much narrower than the larger and more dorso-ventrally convex P. procerus (Merian, 1844), which shares a similar geological record. P. cantamessae is similar to other Paraseraphs from Europe, and particularly to P. armoricensis (Cossmann, 1897), and was likened to that taxon by Jung (1974), but occurs after that species disappears during the Bartonian. Paraseraphs canatemessae is similar also to P. propedistortus (de Gregorio, 1880), being slender with an acute spire, but the latter is restricted to the Lutetian of the Mediterranean.
