Study of a nearly complete skeleton of a small amniote, preserved as part and counterpart in Upper Carboniferous limestone slabs of the Hamilton Quarry, Kansas, indicates that it is a new genus and species of varanopid synapsid. Archaeovenator hamiltonensis gen., and sp. nov. is the oldest known varanopid. Phylogenetic analysis indicates that it is the sister taxon to all other known varanopids. Discovery of this new varanopid is important because it improves our knowledge of the terrestrial fauna of the Hamilton quarry, expands the known diversity of Late Carboniferous basal synapsids, and extends the fossil record of Varanopidae deeper within the Stephanian. Varanopidae has the longest fossil record (Late Carboniferous – upper Middle Permian) of all known clades of basal synapsids.

Abstract The Australian pterosaur record is poor by world standards, comprising fewer than 20 fragmentary specimens. Herein, we describe the new genus and species Ferrodraco lentoni gen. et sp. nov., based on the most complete pterosaur specimen ever found in Australia, and the first reported from the Winton Formation (Cenomanian–lower Turonian). The presence of premaxillary and mandibular crests, and spike-shaped teeth with subcircular bases, enable Ferrodraco to be referred to Anhangueria. Ferrodraco can be distinguished from all other anhanguerian pterosaurs based on two dental characters: the first premaxillary and mandibular tooth pairs are small; and the fourth–seventh tooth pairs are smaller than the third and eighth ones. Ferrodraco was included in a phylogenetic analysis of Pterosauria and resolved as the sister taxon to Mythunga camara (upper Albian Toolebuc Formation, Australia), with that clade occupying the most derived position within Ornithocheiridae. Ornithocheirus simus (Albian Cambridge Greensand, England), Coloborhynchus clavirostris (Valanginian Hastings Sands, England), and Tropeognathus mesembrinus (upper Aptian–lower Albian Romualdo Formation, Brazil) were resolved as successive sister taxa, which suggests that ornithocheirids were cosmopolitan during the Albian–Cenomanian. Furthermore, the stratigraphic age of Ferrodraco lentoni (Cenomanian–lower Turonian) implies that anhanguerians might have survived later in Australia than elsewhere.

New Genus And Species

A new genus and species, Glanomerope virgoferroa gen. et sp. nov., the first Permian record of a scorpionfly from Germany, is described from the Niedermoschel black shale, Meisenheim Formation, Lower Rotliegend of the Saar-Nahe basin. It is assigned to the Protomeropidae, the oldest known family of the holometabolous superorder Panorpida, ranging from the Bashkirian-Moscovian (Late Carboniferous) to the Roadian. It confirms that this family was very diverse in Central Europe during the Early Permian. Protomeropidae possibly became extinct in the course of major climatic changes that progressively affected the supercontinent Pangea after the Artinskian, although generally these changes seem to have more severely affected some other insects such as the palaeopteran Dictyoneuridae than holometabolous groups.

Lunge Feeding

The early evolution of toothless baleen whales (Chaeomysticeti) remains elusive despite a robust record of Eocene-Oligocene archaeocetes and toothed mysticetes. Eomysticetids, a group of archaic longirostrine and putatively toothless baleen whales fill in a crucial morphological gap between well-known toothed mysticetes and more crownward Neogene Mysticeti. A historically important but perplexing cetacean is “Mauicetus” lophocephalus (upper Oligocene South Island, New Zealand). The discovery of new skulls and skeletons of eomysticetids from the Oligocene Kokoamu Greensand and Otekaike Limestone permit a redescription and modern reinterpretation of “Mauicetus” lophocephalus, and indicating that this species may have retained adult teeth. A new genus and species, Tokarahia kauaeroa, is erected on the basis of a well-preserved subadult to adult skull with mandibles, tympanoperiotics, and cervical and thoracic vertebrae, ribs, sternum, and forelimbs from the Otekaike Limestone (>25.2 Ma). “Mauicetus” lophocephalus is relatively similar and recombined as Tokarahia lophocephalus. Phylogenetic analysis supports inclusion of Tokarahia within the Eomysticetidae alongside Eomysticetus, Micromysticetus, Yamatocetus, and Tohoraata, and strongly supports monophyly of Eomysticetidae. Tokarahia lacked extreme rostral kinesis of extant Mysticeti and primitively retained a delicate archaeocete-like posterior mandible and synovial temporomandibular joint, suggesting that Tokarahia was capable of at most, limited lunge feeding in contrast to extant Balaenopteridae, and utilized an alternative as-yet unspecified feeding strategy.

Triangular Area

The Palaeozoic archaeorthopteran order Cnemidolestodea Handlirsch, 1937 (sensu Béthoux, 2005; not sensu Aristov, 2014) currently comprises only the family Cnemidolestidae Handlirsch, 1906. They are easily characterized by the presence of a more or less triangular area delimited by the vein MA and the first anterior fork of MP+CuA+CuPa, this last vein having several parallel posterior branches. Dvořák et al. (2021) listed the included genera, and described the new genus and species Piesbergopterum punctatum from the Moscovian of Piesberg (Germany), characterized by the presence of a pattern of rounded spots in numerous cells all over the forewings. Nel & Poschmann (in press) noticed that the Cnemidolestidae show an important diversity of patterns of coloration on their forewings, possibly related to cryptic behaviors in the vegetation.

AbstractKazachostylops occidentalis Nesov, 1987b, based on partial maxilla and dentary from the upper Paleocene Zhylga locality in South Kazakhstan, is redescribed. A new phylogenetic hypothesis of Arctostylopida is proposed based on phylogenetic analysis of 26 characters and 17 taxa. Kazachostylops is recovered as a sister taxon to the Arctostylopinae, the advanced clade of Asian and North American arctostylopids characterized by pseudohypocone on upper molars and reduced trigonid of lower molars, with the ectolophid being attached labial on the trigonid. Kazachostylops differs from more basal arctostylopids (Asiostylops, Allostylops, Bothriostylops, and Wanostylops) by higher-crowned molars, M1–3 metaconule absent, m1–3 entoconid connected with ectolophid by entolophid, and m2 wider than m1 and m3. Principal component analyses of the upper and lower dentition of arctostylopids show great distinctness of Kazachostylops from other members of the group. The arctostylopid taxa are reviewed, and the new genus Enantiostylops is erected for ‘Sinostylops’ progressus Tang and Yan, 1976 from the lower Eocene of China, because of uniquely concave parastylar area on upper molars.UUID: http://zoobank.org/a46d8f29-fd73-4e59-88dc-fcc55b12d1d3

A collection of 17 isolated rodent molars from a cave in the eastern part of Duivelsklip, Curaçao, Dutch West Indies, isdescribed as Dushimys larsi, new genus and species. The new species is characterized by relatively large size, broad mo-lars, absence of mesolophid and presence of anterolophid and anterolabial cingulum on m3, absence of metaloph on M3,and m2 with three roots. Phylogenetic analysis could not conclusively resolve the position of the new species, and it isprovisionally regarded as a representative of an otherwise unknown oryzomyine genus. The material is likely middle Pleistocene in age.

A new genus and species, Lissaclita melaniae (Tetraclitidae), is described from the Gulf of California, Baja California Sur, Mexico. Lissaclita has a secondarily divided single row of parietal tubes without septa, lack of tubes in the radii, diametric shell growth, and a membranous basis. This combination of characters does not agree with any currently described subfamily within the Tetraclitidae. Lacking a detailed phylogenetic analysis of the entire family, we place the new genus in the Tetraclitidae without assigning it to a subfamily.

A new genus and species Allorapisma chuorum gen. sp. nov. is described from the Early Eocene locality at Republic, Washington, U.S.A. The forewing venation of Allorapisma is most similar to that of the genus Principiala Makarkin & Menon from the Early Cretaceous of Brazil and Britain. A new, informal suprageneric taxon consisting of these genera is proposed, the Principiala group. The habitats of extant and fossil Ithonidae are briefly discussed.
