Fossil plants in the Tierra del Fuego Province, Argentinean Patagonia, are known since the expedition of Charles Darwin to the Beagle channel. However, only a few fossil plants have been described. In this work, a new fossil leaf collection is studied. It was collected from outcrops of the Cullen Formation (middle Miocene) located in the Atlantic coast of Tierra del Fuego, Patagonia, Argentina. Over two hundred pieces were collected in three localities: Cabo Espiritu Santo, Arroyo Beta, and Canadon de los Mineros. The taxonomic studies reveal the presence of nine fossil species; six of them are related to Nothofagus Blume (Nothofagaceae), one to Myrtaceae, one to Gesneriaceae and the last one to the genus Podocarpus Labill. Our study agrees with previous ones, which suggested that the Nothofagaceae were dominant in the Cullen Formation area, and support the development of a cold temperate and humid forest in the area. The megafloral association studied result similar to others paleofloras developed in Patagonia during the Neogene, according to the cluster analysis performed. Finally, it was characterized like a Subantartic paleoflora sensu Troncoso & Romero.
阿根廷巴塔哥尼亚火地岛省的植物化石，自查尔斯·达尔文远征比格海峡以来就已为人所知。然而，只有少数植物化石被描述过。在这项工作中，研究了一个新的叶子化石集。它是从位于阿根廷巴塔哥尼亚火地岛大西洋海岸的卡伦组（中新世中期）的露头中采集的。在圣埃斯皮里图角（Cabo Espiritu Santo）、阿罗约贝塔（Arroyo Beta）和米涅罗斯运河（Canadon de los Mineros）三个地方收集了200多件藏品。分类学研究揭示了九个化石物种的存在；其中6个与Nothofagus Blume（Nothofagaceae）有亲缘关系，1个与Myrtacee有亲缘关系；1个与苦苣苔科有亲缘关系。我们的研究与以前的研究一致，表明在卡伦组地区，Nothofagaceae占主导地位，并支持该地区冷温带湿润森林的发展。根据进行的聚类分析，巨型植物群协会研究的结果与新第三纪巴塔哥尼亚形成的其他古植物群相似。最后，它被描述为一个亚南极古植物群，感觉Troncoso和Romero。

Two new species Paraconularia are described from rocks of lower–middle Permian (Kungurian to Capitanian) age in the Las Delicias Formation, northeastern of Torreon, into the State of Coahuila, Mexico. These species are the first conulariids reported from the Permian of Mexico, and they have affinities with faunas of the Grandian Province from the Palaeoequatorial Realm.

The large hadrosauroid dinosaur Eolambia caroljonesa was named in honor of Carol Jones, the discoverer of the place where the type specimens were found. However, according to the article 31.1.2 of the ICZN, the form caroljonesae should have been used and, thus, caroljonesa represents an incorrect original spelling subject to a justified emendation. Such emendation is required in cases on which the incorrect original spelling of a species-group name must be corrected, as stated by the article 32.5.1 of the ICZN. Therefore, based on the express application of the nomenclatural rules, the name of the species must be corrected to Eolambia caroljonesae.

The first record for Uruguay of the dinomyid rodent Tetrastylus Ameghino, an almost complete right mandible from the upper Miocene Camacho Formation, is described. According to the p4 and m3 morphology it is inferred a juvenile-subadult ontogenetic stage for this specimen.
