Abstract Early Jurassic flora in the Romanian Carpathians is well known by the study of fossil foliages found in the "Liassic" coaly deposits. The identified flora belongs to bryophytes, pteridophytes, pteridosperms, cycads and gymnosperms. With a few exceptions, few data have been published as regards the Early Jurassic lignoflora from the Romanian Carpathians. The present xylotomic study performed on a rich collection of petrified woods found in the Lower Jurassic coaly deposits from the Holbav and Cristian areas in the Bra ov region, located in the easternmost part of the South Carpathians, allowed the identification of five newly described Early Jurassic gymnosperm lignotaxa, such as Agathoxylon holbavicum sp. nov., Brachyoxylon holbavicum sp. nov., B. cristianicum sp. nov., Protophyllocladoxylon holbavicum sp. nov. and Palaeoginkgoxylon sp. This new Early Jurassic gymnosperm lignoflora may shed an outstanding light on the regional paleobiogeographic, paleoecologic and paleoclimatic significance of the Early Jurassic flora in the Romanian Carpathians.
Keywords: Carpathian Early Jurassic Flora, Petrified Forest, Gymnosperms, new taxa.

UPPERMOST CRETACEOUS CALCAREOUS NANNOFOSSILS IN RED PELAGIC SEDIMENTS (ROMANIAN CARPATHIANS)
Acta Palaeontologica Romaniae, 14 (2), 2018: 35 - 44

Abstract Calcareous nannofossil investigations were carried out on successions cropping out in an expanded section situated in the Romanian Carpathians bend area (nearby the Pucheni village, Dambovita River basin). Nannofossil biostratigraphy indicates a Santonian - late Maastrichtian age for the investigated deposits. The studied red and variegated sediments are correlated with similar deposits occurring in the bend region of the Romanian Carpathians.
Keywords: Santonian-Maastrichtian interval, Romanian Carpathian Bend, red marine beds, nannofossil biostratigraphy.

Abstract Since decades the taxonomic status of the "orbitoliniform" larger benthic foraminifer Paracoskinolina? jourdanensis (Foury & Moullade) described from the Barremian of France is ambiguous. Based on material mainly from the Valanginian and Barremian of Romania and the Valanginian of Serbia, it is taxonomically revised. It is here redescribed as Moulladella jourdanensis (Foury & Moullade) n. gen., nov. comb. (synonym Conicopfenderina? balkanica Peybernes, 2004, Valanginian of Bulgaria) removed from the Orbitolinidae and assigned to the Pfenderinidae. M. jourdanensis is palaeobiogeographically restricted to a stripe along the northern Neotethyan margin, with occurrences stretching from the Spanish Pyrenees to Bulgaria.
Keywords: Foraminiferida, taxonomy, biostratigraphy, palaeobiogeography, Lower Cretaceous.
