Seed morphology of the paleotropical tribe Paropsieae (Passifloraceae, Malpighiales), and paleobotanical implications

The fossil record of the diverse subfamily Passifloroideae (>750 species and 17 genera) is relatively poor. Despite distinctiveness its leaves (glandular often emarginate), most fossils from this group have been described seeds. Fossil seeds recovered Europe, North South America. A lack information on seed morphology for all genera tribes has prevented a tribe-level identification better understanding their biogeographic patterns. divided into three tribes: Passifloreae with 10 genera, Paropsieae six monotypic Jongkindieae. This study provides new descriptions 15 5 mostly Afrotropical tribe based herbarium material, introduces an online database key 100 compiled literature direct observations. Our shows low morphological diversity among in comparison to much larger within Passifloreae. Some rare morphologies are only present can be used assign tribe. Within Paropsieae, Androsiphonia that very distinct those other also rest subfamily. genus Paropsia exhibits two main morphotypes, while Barteria, Paropsiopsis Smeathmannia similar highly conserved morphology. These results suggest living or cannot identified confidently solely characters.

Flying squirrels (Rodentia, Sciuridae, Sciurinae, Pteromyini) have a long and complex history in North America. First recorded during the Late Eocene, they vanished early Miocene (at about 9 Ma) only to re-appear Pliocene Pleistocene. The first flying be after this gap are surprisingly attributed Eurasian genus of giant squirrel Miopetaurista. These just two specimens from Florida that purportedly belong Miopetaurista webbi, an endemic species. In work we review these occurrences further describe new specimen Early (latest Hemphillian or Blancan) Gray Fossil Site Tennessee, which may represent oldest record We validate their attribution webbi found species probably closely related thaleri, known occurrence Miopetaurista eastern America is puzzling, as it set far away geographical range its sister taxon, extant Petaurista. hypothesize Miopetaurista, was linked warm forested environments, dispersed into via Bering Land Bridge phases frame major faunal dispersal involving many other taxa. Later climatic cooling isolated warmer refuges, such Florida, until finally became extinct
