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...

of the open ocean as the source of the material as in the case of the Sargasso-sea faunas. Such is the Genessee shale which like the Genundewa limestone contains in the abundant Styliolinas a typical planktonic element, the Genundewa limestone representing a Devonian pteropod-ooze. The widely extending Chatanooga shale is characterized by the conodonts, now recognized as the teeth of cyclostome...

A small, protected karstic feature exposed in a limestone quarry in Bermuda preserved abundant sedimentary and biogenic materials documenting a transgressive phase, still-stand, and regressive phase of a sea-level in excess of 21.3 m above present during Marine Isotope Stage (MIS) 11 (400 ka) as determined by U/Th dating and amino acid racemization. Cobbles and marine sediments deposited during...
