We describe a new lizard taxon, Stefanikia siderea gen. et sp. nov., from the early-middle Eocene locality of Messel in Germany based on a nearly complete skeleton, which we studied using μCT methods. It shares many characters with the Eocene taxon Eolacerta, which is broadly distributed in the Eocene of central and Western Europe, but is much smaller and shows several important anatomical differences. The new discovery sheds light on the paleodiversity of these lizards in the Eocene of Europe, and the new family name Eolacertidae is proposed to encompass Eolacerta and Stefanikia. The relationships of Eolacerta have been intractable. Our phylogenetic analyses confirm that Eolacertidae is a member of the clade Lacertiformes and provide strong support for a sister-group relationship to Lacertidae. In some places, skin impressions are preserved, displaying the body scalation. As such, the exquisitely preserved specimens of Eolacertidae from Messel provide new insight into the morphology and ecology of lizards on the stem of Lacertidae, Europe’s dominant group of living reptiles. http://zoobank.org/urn:lsid:zoobank.org:pub:DFD01563-A913-4286-B64B-E0912474FD08 相似文献

We document Late Eocene vertebrate footprints from the Tarom Mountains of Iran that represent a significant addition to the record of proboscidean and perissodactyl footprints. These footprints are from sandstones and tuffaceous sandstones of strata equivalent to the Kond Formation that overlie middle Eocene sedimentary rocks and are overlain by Oligocene volcanics. The footprints are preserved at 16 tracksites from 10 distinct stratigraphic levels. The mammal footprints include the oldest known proboscidean tracks, assigned to Proboscipeda enigmatica Panin & Avram and to cf. Proboscipeda isp. Evident perissodactyl tracks are common, tridactyl footprints with distinct digit shapes and proportions assigned to the new ichnogenus and ichnospecies Moropopus elongatus. Footprints of small, hopping, rodent-like mammals are identified as Musaltipes taromi new ichnospecies. Other mammal footprints from the Tarom tracksites are indeterminate, and bird footprints are assigned to Avipeda isp. The Tarom tracksites document the oldest record of proboscidean footprints, and this indicates that proboscideans had reached the northern shore of Tethys by Late Eocene time. The abundance and distinctiveness of the Tarom perissodactyl tracks mirrors the abundance and diversity of moropomorph perissodactyls during the Middle-Late Eocene. The Tarom tracksites are the most extensive record of Eocene vertebrate footprints known from Iran. http://zoobank.org/urn:lsid:zoobank.org:pub:F430F9DB-728F-4162-9791-DC2A5CC5ED43 相似文献

A new genus and species, Succinapion telnovi n. gen. et n. sp. (Coleoptera: Curculionoidea: Brentidae: Apioninae: Kalcapiini) is described and illustrated from Upper Eocene Baltic amber. The new genus is similar to the genus Melanapion Wagner, 1930 but differs from it in having femora ventrally with spine at distal 1/3, simple claws, a longer rostrum, elytra weakly widened towards apex, longer antennae and slightly narrower elytral striae. http://www.zoobank.org/urn:lsid:zoobank.org:pub:2A95C49D-5589-4ACA-8A87-0DDF635BA25E 相似文献

The genus Pseudaeginella is analysed herein by cladistic methods based on a morphological data matrix of 49 characters × 18 terminal taxa. Based on the results, we comment on the phylogenetic position of Paradeutella within Pseudaeginella, and we propose Pseudaeginella multispinosa comb. nov. and Pseudaeginella tanzaniensis comb. nov. Pseudaeginella freirei sp. nov. is described from the Abrolhos Bank, north-eastern Brazil. We provide an updated key to the Pseudaeginella species. http://www.zoobank.org/urn:lsid:zoobank.org:pub:F573E845-822E-41D6-8F58-FE54C5653A53 相似文献

Three new species of Crenitis Bedel, 1881 are described from South Africa; C. castellus sp.n. and C. rupestris sp. n. from the KwaZulu-Natal Drakensberg, and C. quagga sp.n. from the Western Cape Province. All three new species were found in madicolous habitats, which appear to be characteristic for a number of species of the genus. A revised key to African species of Crenitis is included. http://zoobank.org/urn:lsid:zoobank.org:pub:18BE876C-46CB-4AD5-9BB0-EA6F8D711F09 相似文献

In this paper, fossil rodents (Hystricognathi: Caviomorpha) from the late Quaternary of the southwestern State of Piauí, northeastern Brazil, are described. The material comes from archaeological/palaeontological sites located in the region of the Serra da Capivara. The late Quaternary taxa of this region include Galea Meyen, 1832, Kerodon rupestris Wied-Neuwied, 1820, Hydrochoeridae indet., Dasyprocta Illiger, 1811, cf. Myocastor Kerr, 1792, Thrichomys Trouessart, 1880, Phyllomys Lund, 1839, Coendou magnus Lund, 1839 and a new taxon with chinchilloid affinities. The Coendou magnus and cf. Myocastor material represents the northernmost records of these taxa. The unexpected presence of a new extinct taxon contributes to the understanding of the ancient rodent faunas from South America. Today, the studied area is located within the Caatinga Biome but some of the fossil taxa, such as Hydrochoeridae and cf. Myocastor, indicate wetter environments and permanent water bodies during the late Pleistocene–early Holocene. http://www.zoobank.org/urn:lsid:zoobank.org:pub:92711BC3-8997-4474-A8AF-83DF4F91BB48 相似文献

The ability of beetles to form defensive spheres is a rare trait and confined to representatives in the families Clambidae, Leiodidae and Hybosoridae. However, the most compact spheres are formed by members of the Neotropical genus Ceratocanthus (Ceratocanthinae: Hybosoridae). A representative in Dominican amber described as Ceratocanthus emarginatus sp.n. differs from all known members of the genus by its unique notched clypeus. Additional specimens of at least two other species suggest that these sphere-forming beetles were fairly diverse in the Dominican amber forest. http://www.zoobank.org/urn:lsid:zoobank.org:pub:4329D0DA-57BD-4CEA-9464-ABD5D1577FC9 相似文献

The poorly known pleurodiran turtle ‘ Stereogenys’ libyca (Podocnemididae, Erymnochelyinae) is studied in this paper. It was defined in lower Oligocene levels of the Fayum Depression (Egypt), its presence in the upper Eocene levels of the same area being confirmed here. Its holotype corresponds to an almost complete and well preserved shell, that was until recently considered to be lost. No photograph of material attributable to this species had hitherto been published. Thus, the current knowledge about it was exclusively based on the limited information published more than a century ago. The recently rediscovered holotype, and also more than fifteen additional historical but unpublished specimens recognized here as attributable to this species, are studied in this paper. This species is attributed to a new genus, Andrewsemys, and the new combination Andrewsemys libyca is proposed. http://www.zoobank.org/urn:lsid:zoobank.org:pub:6D87831A-4510-4A3E-A624-C40FD644F448 相似文献

The distinctive braconine wasp genus Rhytimorpha Szépligeti is distributed through Africa and the Near East. We provide photographic illustrations of the type specimens of the two species of Rhytimorpha known up to the present, R. coccinea Szépligeti and R. nigriceps Szépligeti. Previous published records of R. coccinea from Israel by J. Papp are confirmed. A new species, R. pappi Quicke & Butcher sp. n. is described based on a female from Holot Agur, a semi-desert area in the Negev Dunes in northeastern Sinai Peninsula. http://www.zoobank.org/urn:lsid:zoobank.org:pub:B5CDA65C-5341-4A61-9C85-2A7A70D7D4C1 相似文献

Based on the examination of old literature, the names of two species of Batillus Schumacher, 1817, a subgenus of Turbo Linnaeus, 1758, are revised. Turbo cornutus [Lightfoot], 1786 should be restricted to the species endemic to southern China and Taiwan. Turbo chinensis Ozawa & Tomida, 1995 is the junior synonym of T. cornutus. The species of Japan and Korea has long been misidentified with T. cornutus. Turbo japonicus Reeve, 1848 has been used for two very different species: one from Mauritius and another from Japan, with the species from Mauritius being valid, and a member of the subgenus Marmarostoma Swainson, 1840, while the Japanese/Korean species, lacking an available name, is provided with a new replacement name, T. sazae nom. nov. http://www.zoobank.org/urn:lsid:zoobank.org:pub:7E99BA4B-CEB5-4510-BC5E-7852232926B8 相似文献

Diplecogaster umutturali sp. n. is described from five specimens, ranging from 9.5 to 26.9 mm in standard length. This clingfish is known to occur only at three localities along the northern Levant coasts, eastern Mediterranean Sea and is the third known species of the genus Diplecogaster in the Mediterranean and Black Seas. The species is distinguished from all its congeners in having a small snout, short caudal peduncle, large eyes, short anal fin and upper attachment of gill membrane opposite the 7th-8th pectoral ray. Diplecogaster umutturali sp. n. shows a 5.3% genetic divergence from its close relative D. bimaculata at the cytochrome oxidase I locus (COI). http://www.zoobank.org/urn:lsid:zoobank.org:pub:376298FE-C8A7-44BB-9B12-721E41D7F355 相似文献
