Molecular features of fossil organic matter in remains of the Lower Cretaceous fern Weichselia reticulata from Przenosza basem

Przenosza (Western Carpathians, Poland) is an important palaeobotanical Cretaceous basement with morphologically well-preserved plant remains. Both the morphology of the macroremains and the microscopic examination of isolated plant cuticles correspond to typical species of coastal swampy palaeoenvironments, mainly the fern Weichselia reticulata (Stokes & Webb). After isolation of the plant rem...

Were early Tertiary monotremes really all aquatic? Inferring paleobiology and phylogeny from a depauperate fossil record.

The recent study of monotreme paleobiology and phylogeny by Phillips et al. (1) emphasized that the crown group Monotremata may have diverged relatively recently. However, they failed to discuss several aspects of the monotreme fossil record and functional morphology that may have a significant bearing on their conclusions. It is important to note that the paucity of tachyglossid like monotreme...

Chronology for the Cueva Victoria fossil site (SE Spain): Evidence for Early Pleistocene Afro-Iberian dispersals.

Cueva Victoria has provided remains of more than 90 species of fossil vertebrates, including a hominin phalanx, and the only specimens of the African cercopithecid Theropithecus oswaldi in Europe. To constrain the age of the vertebrate remains we used paleomagnetism, vertebrate biostratigraphy and (230)Th/U dating. Normal polarity was identified in the non-fossiliferous lowest and highest strat...
