An evening bat (Chiroptera: Vespertilionidae) from the late Early Eocene of France, with comments on the antiquity of modern batsSuzanne J. Hand, Bernard Sigé, Michael Archer and Karen H. BlackKeywords: evolution; palaeobiogeography; Prémontré; Western Europe; Ypresiandoi: 10.18563/pv.40.2.e2 Abstract Bats are among the most numerous and widespread mammals today, but their fossil record is comparatively meagre and their early evolution poorly understood. Here we describe a new fossil bat from dental remains recovered from late Early Eocene sediments at Prémontré, northern France. This 50 million-year-old bat exhibits a mosaic of plesiomorphic and apomorphic dental features, including the presence of three lower premolars, a single-rooted p3, short p4 with metaconid, myotodont lower molars and a tall coronoid process of the dentary. This combination of features suggests it is an early member of Vespertilionidae, today’s most speciose and geographically widespread bat family. The Prémontré bat has bearing on hypotheses about the origins of vesper or evening bats (Family Vespertilionidae), as well as crown-group chiropterans. Article infos Published in Vol.40-2 (2016) |

First record of the genus Megaderma Geoffroy (Microchiroptera: Megadermatidae) from Australia.Suzanne J. HandKeywords: Australia; Chiroptera; Megaderma; Megadermatidae; Pliocene; Rackham's Roost Site; RiversleighAbstract A new Tertiary megadermatid is described from Rackham's Roost Site, a Pliocene limestone cave deposit on Riversleigh Station, northwestern Queensland, Australia. It appears to represent the first Australian record of Megaderma GEOFFROY, 1810, a genus otherwise known from Tertiary African and European taxa and the living Asian species M. spasma (LINNAEUS, 1758) and M. (Lyroderma) lyra PETERS, 1872. Megademza richardsi n. sp. is one of the smallest megademiatids known. It exhibits a mixture of plesiomorphic and autapomorphic features, the latter appearing to exclude it from being ancestral to any living megadermatid. The new species is one of eight megadermatids identified from the Australian fossil record, most of which are referable to Macroderma MILLER, 1906.

An Australian Miocene Brachipposideros (Mammalia, Chiroptera) related to Miocene representatives from FranceBernard Sigé, Suzanne J. Hand and Michael ArcherKeywords: Australia; bats; Chiroptera; MioceneAbstract A new middle Miocene hipposiderid bat is described from a limestone deposit on Riversleigh Station in north-western Queensland. Hipposideros (Brachipposideros) nooraleebus n. sp. is the first record of this subgenus from anywhere in the world outside of France. The palaeoecological setting of the fossil bats appears to have been a relatively quiet, sunny lime-enriched tropical pool that contained tortoises, crocodiles and fish. It is possible that the bats were washed into the pool from an adjacent cave. Article infos Published in Vol. 12, Fasc. 5 (1982) |
