|Sato T.,Kase T., Shigeta Y., De Ocampo R.S.P., Ong P.A., Aguilar Y.M., Mago W. (2012) Newly Collected Jurassic Ammonites from the Mansalay Formation, Mindoro Island, Philippines // Bull. Natl. Mus. Nat. Sci., Ser. C, 38, P. 63–73. |
Four species of Jurassic ammonites, newly discovered from the Mansalay area in Oriental Mindoro, Philippines, are described and figured herein. Described are Physodoceras cf. gortanii and Perisphinctes (Liosphinctes) sp. from the Amaga River valley near Mansalay, and Perispinctes (Liosphinctes) cf. laevipickeringius and an unidentifiable Perisphinctid from Colasi Point south of Mansalay. This assemblage is indicative of middle Oxfordian age as a whole, in concordance with the correlation previously proposed. It indicates an obviously close affinity with the Tethys–Pacific faunas.
