A new species of <i>Armigatus</i> (Clupeomorpha, Ellimmichthyiformes) from the Late Cretaceous of Morocco, and its phylogenetic relationships

<p>A new species of the genus <i>Armigatus</i> is described from the Cenomanian/early Turonian Akrabou Formation of Morocco. Similar to other ellimmichthyiforms, <i>Armigatus oligodentatus</i>, sp. nov., has parietals in contact with each other along the midline, has a beryciform foramen in the anterior ceratohyal, and lacks the recessus lateralis. The new species is placed in the genus <i>Armigatus</i> based on the incomplete predorsal series of heart-shaped scutes with rounded and smooth posterior border. However, this new species differs from the other known members of the genus in the lack of teeth on the parasphenoid and endopterygoid bones. This is the first report of a species of <i>Armigatus</i> from southeastern Morocco; previously, the genus was known only from the Late Cretaceous deposits of the eastern part of the Tethys. Therefore, <i>Armigatus oligodentatus</i> sp. nov. extends the distribution of the genus across the Tethys Sea and provides valuable information about the evolutionary history and paleoecology of the Ellimmichthyiformes.</p> <p>http://zoobank.org/urn:lsid:zoobank.org:pub:FD65FEA4-E219-4892-8AA4-6254E60EE5DB</p> <p>SUPPLEMENTAL DATA—Supplemental materials are available for this article for free at <a href="http://www.tandfonline.com/UJVP" target="_blank">www.tandfonline.com/UJVP</a></p> <p>Citation for this article: Vernygora, O., and A.

The fishes of Bukwa, Uganda, a lower Miocene (Burdigalian) locality of East Africa

<p>Renewed research at the early Miocene fossil site of Bukwa in northeastern Uganda has resulted in new fossil finds, including fish, with representatives of two families, Cichlidae and Alestidae. Although the two families were previously briefly reported from Bukwa, we here give a more detailed account of the fishes based on newly collected material. The cichlid material, mainly composed of vertebrae, can be tentatively assigned to one or more species of Pseudocrenilabrinae. The alestid material, comprising a diversity of teeth, likely represents several different species of <i>Alestes, Brycinus</i>, and/or <i>Bryconaethiops</i>. Although the ichthyofaunal diversity of Bukwa is low, the fishes are important for indicating the paleoenvironment and hydrographic connections of Bukwa. The early Miocene was a critical time for African faunas, because it was during this time that the Afro-Arabian and Eurasian plates came into contact with one another, ending the long isolation of Africa, which, along with rifting in East Africa, created new terrestrial and hydrological connections allowing faunal interchanges. Bukwa is one of only a few African early Miocene localities known that sample fish and, based on these fish, the site probably represents an area of interconnected lakes and large rivers, including floodplains.</p> <p>SUPPLEMENTAL DATA—Supplemental materials are available for this article for free at <a href="http://www.tandfonline.com/UJVP" target="_blank">www.tandfonline.com/UJVP</a></p> <p>Citation for this article: Murray, A.
