Abstract Nummulites fayumensis n. sp. and Nummulites tenuissimus n. sp. are described from the Munqar El-Rayan Section, Fayum, Egypt. Nummulites tenuissimus belongs to the N. partschi group, while N. fayumensis belongs to the N. gizehensis group, based on diameter and protoconch sizes, septal shape and granulations. Both new species are of Lutetian age, assigned to SBZ14/15, and encountered in shallow-marine facies. Wadi El-Rayan is an important site for vertebrate fossils in Egypt and the abundant larger benthic foraminiferal assemblage provides insight into paleoenvironmental parameters associated with the deposition of Eocene-age rock units of the Munqar El-Rayan Section.

A New Species

AbstractA new species of Hypolophites (Chondrichthyes, Myliobatiformes) is described from an assemblage of isolated pavement teeth recovered from the Lower Clayton Limestone Unit of the Midway Group (Paleocene) near Malvern, Arkansas. These teeth were collected from several localized lag deposits containing an abundance of chondrichthyan and osteichthyan teeth, invertebrate remains, and trace fossils indicative of a marginal-shallow marine depositional environment. To date, only four additional species of Hypolophites have been reported from Paleocene deposits that occur along the west coast of central-northern Africa and in central New Jersey, USA. The identification of Hypolophites beckeri n. sp. in southwestern Arkansas extends the distribution of this biostratigraphically significant genus ~1,750 km westward into the Mississippi Embayment and Gulf Coastal Plain of the USA. The distribution of Hypolophites species during the Paleocene attests to the uniformity of shallow marine shelves between western Africa and the Atlantic and Gulf Coastal Plains of the USA, as well as myliobatiform diversification following the K/Pg mass extinction event.UUID: http://zoobank.org/3a1580d1-a2f4-49b6-8170-69a778c49181

AbstractThree durophagous mosasaur species are represented by isolated teeth in the Upper Cretaceous (Maastrichtian) phosphatic beds of Morocco. Globidens phosphaticus nov. sp. is characterised mainly by a strong heterodonty, with mid-posterior teeth being bulbous, irregularly oval in crosssection, and having an inflated posterior surface, a large eccentric located and recurved apical nubbin, vertical sulci on medial and lateral faces, no carinae and an enamel surface covered by anastomosing ridges. Teeth of Prognathodon currii are broad and tall, straight cones, slightly swollen at the base, and with two serrated carinae. These two taxa have been collected from all the phosphatic series (lower to upper Maastrichtian) in the Ganntour Basin (Morocco). Globidens phosphaticus nov. sp. is probably also represented at other Maastrichtian phosphatic sites along the southern margin of the Mediterranean Tethys. Prognathodon currii was previously known only from the Upper Cretaceous phosphates of Negev. Of the third taxon, Carinodens belgicus, only a single tooth (now lost) is known from the Oulad Abdoun Basin (Morocco); this is low, swollen, laterally compressed and bicarinate with a large apical nubbin. Previous records of this species include Europe and Brazil.

Abstract. The orbitoidal larger foraminifer Omphalocyclus maldonensis n. sp. is described from the Maldon Inlier of northwestern Jamaica, being the first record of this genus from the island. The limestone in which it occurs contains the Upper Cretaceous (Upper Maastrichtian) Titanosarcolites rudist fauna, together with larger foraminiferal specimens identified as Orbitoides megaloformis Papp &amp; Küpper. The new species differs from Omphalocyclus macroporus, the only other widely recognized species, in possessing a much smaller nucleus. At least some of the earlier records of Omphalocyclus from the Upper Cretaceous of Venezuela and Cuba should probably be referred to O. maldonensis.

Recently Dr. R. N. Sinha, of the Canadian Department of Agriculture, sent in for determination some spider mites causing serious damage to barley in Manitoba. Previously this same mite had been collected in North Dakota and Oregon. The mites proved to be an undescribed species of Tetranychus, a genus not usually associated with grasses.

The oligopygoid echinoidHaimea bajasurensisn. sp. is described from middle lower Eocene (”Capay Stage”) shallow-marine sandstones in the middle part of the Bateque Formation and shallow-marine limestones in the upper part of the Tepetate Formation, Baja California Sur, Mexico. The new species is both the earliest and the westernmost oligopygoid, and the first occurrence ofHaimeain North America.
