HOLOTYPE: ALMNH 2792 (figs. 2–4, 7, 10, 11), from the Early Campanian Mooreville Chalk (unnamed member below the Arcola Limestone Member), Harrell Station Paleontological Site, Marion Junction, Dallas County, Alabama: an associated series of six anterior vertebrae (ALMNH 2792 -C; fig. 2), an almost complete left palatoquadrate approximately 125 mm long (ALMNH 2792 -A), most of a ceratohyal approximately 120 mm long (ALMNH 2792 -B), a small fragment of cartilage from the braincase, possibly part of the postorbital process (ALMNH 2792 -D), plus numerous smaller indeterminate fragments of tessellated calcified cartilage (hereafter abbreviated to TCC). REFERRED MATERIAL: ALMNH 1040 (fig. 8), including: almost complete right palatoquadrate approx. 143 mm long (ALMNH 1040-A); anterior part of left palatoquadrate (ALMNH 1040-B); two fragments of expanded arcualia from the first vertebra (ALMNH 1040-C); incomplete second vertebra (ALMNH 1040-D); vertebral centrum of uncertain position (ALMNH 1040-E.); heavily abraded vertebral centrum showing fine concentric rings (ALMNH 1040-F); numerous indeterminate fragments of calcified cartilage.Published as part of Maisey, John G., Ehret, Dana J. & Denton, John S.

Cretasquatina Maisey & Ehret & Denton 2020, new genus
No full text<i>Cretasquatina</i> new genus <p>This published work has been registered in ZooBank, http://zoobank.org/ urn:lsid:zoobank. org:pub: 168DD149-4390-4E54-9382-8084F7C39180.</p> <p>DIAGNOSIS: Squatinid elasmobranch in which only the anteriormost two basiventrals of the vertebrae are expanded laterally. First basiventral process much broader distally than proximally, with rounded distal extremities and strongly recurved posterior borders surrounding the second basiventral and almost reaching the third centrum. Second basiventral process sharply angled posterolaterally, straight sided and slightly tapered distally. First vertebra with a vestigial anterior vertebral spool completely enclosed by the first basiventrals, notochordal canal does not reach anterior surface of first basiventral cartilage. Vertebral centra increase in width to centrum 5, then decrease in width. Palatoquadrate orbital process with smoothly rounded apex formed in tessellated cartilage and with a slight anterior projection on its anterolateral surface. Jaws smaller relative to the size of the occipital region than in other squatinids. Teeth unknown.</p> <p> ETYMOLOGY: From the Latin <i>creta</i> (“chalk”) plus <i>squatina</i> (Latin, “skate”).</p>Published as part of <i>Maisey, John G., Ehret, Dana J. & Denton, John S.

FIG. 5 in A new genus of Late Cretaceous angel shark (Elasmobranchii; Squatinidae), with comments on squatinid phylogeny
No full textFIG. 5. AMNH FF 22425, Late Cretaceous, Ramanessin Brook, NJ; isolated first vertebra referred to Cretasquatina: A, anterior view; B, posterior view; C, dorsal view; D, ventral view. The centrum is visible posteriorly but does not emerge onto the anterior surface of the element. Large paired concavities of the cranial-vertebral articulation are present anteriorly. Note also the large size of cartilage tesserae covering surfaces of the arcualia and cotyli (compare with figs. 3, 4).Published as part of Maisey, John G., Ehret, Dana J. & Denton, John S.S., 2020, American Museum Novitates 2020 (3954) on page 1, DOI: 10.1206/3954.1, http://zenodo.org/record/535551
Meridional Water Vapor Transport in Tropical and Sub-Tropical Regions
No full textAirborne differential absorption lidar (DIAL) measurements of tropospheric water vapor and aerosol from south Europe to Brazil in mid-March 2004 are presented and compared to operational analyses of the Euro-pean Center for Medium Range Weather Forecast (ECMWF). The two 2-D sections across the tropical and sub-tropical Atlantic (5°S–37°N) reveal two different meteorological regimes. South of 20°N the Hadley circulation is evident as a humid fountain near the equator with synoptic scale inflow below 4 km (16°N) to 8 km (0°N), upper tropospheric (UT) outflow till 15°N and a dry sub-tropical subsidence layer in between. The 2nd section along the north-west African coast is controlled by mid-latitude dynamics. A deep strato-spheric intrusion is associated with the cyclonic shear along a trough from the Canary Islands towards Gi-braltar. In the sub-tropical layer and the intrusion, H2O mixing ratios q 0.01-0.1 g/kg are measured while q > 0.5 g/kg is found in the lower tropospheric air having been lifted to UT levels. The dynamical features and the water vapor mixing ratios are quite accurately analysed by the ECMWF at T511/L60 operational resolution. Largest deviations arise from shifts of structures/gradients and occasionally from assimilation inaccuracies. The averaged q-bias between both data fields is below 10%. While at mid-latitudes low water vapor regions are associated with filaments of enhanced particle backscatter, the H2O signature of the tropi-cal circulation is not correlated with the aerosol
