Devonian antiarch placoderms from Belgium revisited
-
Anatomical, systematic, and paleobiogeographical data on the Devonian antiarchs from Belgium are reviewed, updated and completed thanks to new data from the field and re-examination of paleontological collections. The material of Bothriolepis lohesti Leriche, 1931 is enhanced and the species better described. An undetermined species of Bothriolepis is recorded from the Famennian of Modave (Liège Province), one species of Asterolepis redescribed from the Givetian of Hingeon and another one described from the Givetian of Mazy (Namur Province). Grossilepis rikiki sp. nov. is recorded from the Famennian tetrapod-bearing locality of Strud (Namur Province) and from the Famennian of Moresnet (Liège Province). It is the first occurrence of Grossilepis after the Frasnian and on the central southern coast of the Euramerican continent. Its occurrence in the Famennian of Belgium may be the result of a late arrival from the Moscow Platform and the Baltic Depression, where the genus is known from Frasnian deposits. Remigolepis durnalensis sp. nov. is described from the Famennian of Spontin near Durnal (Namur Province). Except for the doubtful occurrence of Remigolepis sp. in Scotland, this is the first record of this genus in Western Europe. Its occurrence in Belgium reinforces the strong faunal affinities between Belgium and East Greenland and the hypothesis of a hydrographical link between the two areas during the Late Devonian.

Didelphodus caloris, new species (Mammalia, Cimolesta), from the Wasatchian Wa-0 fauna of the Paleocene-Eocene Thermal Maximum, Clarks Fork Basin, Wyoming
-
The Wasatchian Wa-0 mammalian fauna from the Paleocene-Eocene Thermal Maximum (earliest Eocene) is reasonably well sampled in North America, but mammals of small body size are still poorly known. Here we describe a new species of the insectivore Didelphodus based on a cranial rostrum, both dentaries, and a nearly complete upper and lower dentition, all found by screen-washing. The new species, D. caloris, is the oldest species of the genus known in North America. It differs from later early Eocene Didelphodus in being substantially smaller, in having relatively simple premolars, and in having a more reduced M3 relative to preceding molars. Precursors of Didelphodus are not known with certainty, and the species D. caloris may be an immigrant to mid-continent North America. D. caloris is tentatively interpreted as a dwarfed form like other Wa-0 mammals because of its small size relative to the better-known successor species D. absarokae.

Diet Records for Snakes from Guinea, West Africa
-
We present various predation records based on museum-preserved snakes from southeastern Republic of Guinea, West Africa: Aparallactus niger (Atractaspididae) on an earthworm (Oligochaeta); Crotaphopeltis hotamboeia (Colubridae) on Sclerophrys sp. (Anura; Bufonidae); Grayia smithii (Colubridae) and Natriciteres variegata (Natricidae) on Arthroleptis sp(p). (Anura; Arthroleptidae); Grayia tholloni on Xenopus cf. tropicalis (Anura; Pipidae); Toxicodryas pulverulenta (Colubridae) on Agama cf. sankaranica (Agamidae); Elapsoidea semiannulata moebiusi (Elapidae) on Hemisus cf. guineensis (Anura; Hemisotidae); Naja savannula (Elapidae), Afronatrix anoscopus (Natricidae) and Causus maculatus (Viperidae) on Sclerophrys regularis; Psammophis phillipsii (Psammophiidae) on Trachylepis cf. affinis (Scincidae); Causus maculatus on Ptychadena sp. (Anura; Ptychadenidae); Limaformosa guirali (Lamprophiidae) on Atheris chlorechis (Viperidae); and Atheris chlorechis on Hyperolius sp. (Anura; Hyperoliidae). Diagnostic morphological characters are provided for all snakes involved in these records, as well as clutch sizes for pregnant females (Crotaphopeltis hotamboeia and Causus maculatus). We provide identifications for some insects found in the stomachs of the ingested amphibians.
