The taxonomy, geographic distribution, and paleoenvironmental context of azhdarchid pterosaurs are reviewed. All purported pteranodontid, tapejarid, and azhdarchid specimens from the Cenomanian Kem Kem beds of Morocco are referred to a single azhdarchid taxon, Alanqa saharica. The four proposed autapomorphies of Eurazhdarcho langendorfensis from the lower Maastrichtian Sebeş Formation of Romani...

BACKGROUND Eolambia caroljonesa is known from copious remains from the lower Cenomanian Mussentuchit Member of the Cedar Mountain Formation in eastern Utah; however, the taxon has been only briefly described. Thus, we present herein a complete osteological description of Eolambia. METHODOLOGY/PRINCIPAL FINDINGS The description of Eolambia presented here is based upon the holotype partial skel...

The biostratigraphy of platform carbonates and adjacent basins outcropping in the Prebetic Zone of Alicante, south-eastern Spain, is presented. With this aim, 42 sections from 13 major outcrops, of Aptian–Middle Cenomanian age, were analysed. Ten biostratigraphic units based upon benthonic foraminifers have been distinguished within this interval. Comparison with other previously published bioz...

Harlanjohnsonella annulata Elliott in Granier & Deloffre, 1993, non 1968, was originally described from Cenomanian strata in Serbia. Herein, we report its first occurrence outside the type area, i.e., in Lebanon, and in older strata, i.e., earliest Bedoulian or Late Barremian in age. Our specimens are compared with topotypic material. The species was recently revised by Radoičić & Schlagintweit...

Abstract We investigate the tectonic evolution of Wetterstein and Mieming mountains in western Northern Calcareous Alps (NCA) European Eastern Alps. In-sequence NW-directed stacking thrust sheets this thin-skinned foreland belt lasted from Hauterivian to Cenomanian. In more internal NCA major E-striking intracontinental transform faults dissected at Albian–Cenomanian boundary that facilitated a...

Investigations on the calcareous nannofossils of Gulneri Formation are being done in northern Iraqi Dokan and Pushen areas, Sulimani, Northern Iraq. In this work, one biozone was established based results a detailed examination used to identify fifty species nannofossils; Quadrum gartneri Biozone (CC11) Lucianorhabdus maleformis (CC12) section, although study, three biozones were suggested; Mic...

Abstract Centennial- to millennial-scale climate variations are often attributed solar forcing or internal system variability, but recognition of such in the deep-time paleoclimate record is extremely rare. We present an exceptionally well-preserved, millimeter-scale laminated marlstone from a succession precession-driven limestone-marlstone couplets deposited Western Interior Seaway (North Ame...
