This paper describes a new species of fossil wood, Wataria yunnanica Li et Oskolski, from the Dajie Formation of the middle Miocene in southern Yunnan province, China. This species shows the greatest similarity to the modern genus Reevesia Lindl. from the subfamily Helicteroideae of Malvaceae. The fossil specimen is ascribed to the genus Wataria Terada & Suzuki based on its combination of ring-porous wood and the presence of tile cells. It differs from other Wataria species because vessel groups are common in its latewood. This is the first record of Wataria in China. Other species of this genus have been reported from Oligocene and Miocene deposits in Japan, and from Miocene deposits in Korea. The occurrence of ring-porous wood in the Dajie Formation suggests that there may have been a seasonal (probably monsoonal) climate in southern Yunnan during the middle Miocene.

Ceratodus diutinus, a new species of ceratodont lungfish similar to but not identical with Ceratodus kaupi Agassiz, 1838–1844, is described from the Lower Cretaceous Griman Creek Formation at Grawan and Lightning Ridge in northern New South Wales, Australia, and the Toolebuc Formation at Canary Station near Boulia in western Queensland. The species also occurred in one Late Oligocene–Middle Miocene deposit at North Prospect, Lake Pinpa, South Australia (Namba Formation). This is the first record from Australia of a species of Ceratodus similar to the Triassic ceratodonts of Europe. The Australian species lasted much longer than the related European species, C. kaupi, which is restricted to Triassic deposits.

Abstract A nearly complete dentary with preserved i2, p3 and m1 of a relatively large soricomorph from the Dota locality, Kani Basin, Early Miocene (ca. 18.5 Ma), Nakamura Formation of the Mizunami Group in central Japan, is described as a new species of Plesiosorex. It represents the first record of the genus in East Asia. Plesiosorex fejfari sp. nov. has a slender dentary, posteriorly elongated angular and condyloid processes, p3 with two roots, and m1 without hypoconulid or cingulid. Cladistic analysis of Butselia gracilis and seven species of Plesiosorex shows that Butselia is basally positioned with respect to Plesiosorex, and it seems likely that Plesiosorex originated in Europe at the beginning of the Miocene and expanded its distribution to East Asia and North America during the Early Miocene. Two Middle Miocene North American species are more closely related to each other than to European species of the same age.

AbstractThe order Intejocerida is an enigmatic, short-lived cephalopod taxon known previously only from Early–Middle Ordovician beds of Siberia and the United States. Here we report a new genus, Cabaneroceras, and a new species, C. aznari, from Middle Ordovician strata of central Spain. This finding widens the paleogeographic range of the order toward high-paleolatitudinal areas of peri-Gondwana. A curved conch, characteristic for the new genus, was previously unknown from members of the Intejocerida.UUID: http://zoobank.org/21f0a09c-5265-4d29-824b-6b105d36b791
