FIGURE 6 in Pteropoda (Mollusca, Gastropoda, Thecosomata) from the Paleocene-Eocene Thermal Maximum (United States Atlantic Coastal Plain)
FIGURE 6. Heliconoides mercinensis (Watelet and Lefèvre, 1885). Computed tomography (CT) scan of the specimen pictured in Figure 5.1-3. Resolution 1.9 micrometer/voxel, 165 kV, detector exposure timing 750 ms. For animated version, see online at palaeo-electronica.org/content/2016/1662-pteropoda-from-the-usapetm. By clicking on the image, the interactive 3D model is activated, and the reader can use the mouse to rotate the specimen and change magnification.

FIGURE 1 in Pteropoda (Mollusca, Gastropoda, Thecosomata) from the Paleocene-Eocene Thermal Maximum (United States Atlantic Coastal Plain)
FIGURE 1. Map of the northeastern coast of the USA, showing part of the northern portion of the Atlantic Coastal Plain and the location of the studied cores: BR = Bass River; C = Clayton; WL = Wilson Lake; CD = Cambridge-Dorchester; MCBR = Mattawoman Creek-Billingsley Road. The New Jersey Coastal Plain is the northern section of the Salisbury Embayment. In outcrop, the Fall Line marks the change from Precambrian and Paleozoic rocks of the Piedmont province in the west to the relatively undeformed, slightly dipping Mesozoic and Cenozoic sediments of the Coastal Plain in the east (Gibson and Bybell, 1994). For visual ease, the New Jersey Coastal Plain and the Salisbury Embayment labels are delineated offshore.
FIGURE 5 in Pteropoda (Mollusca, Gastropoda, Thecosomata) from the Eocene/Oligocene boundary interval of three cored boreholes in southern coastal Tanzania and their response to the global cooling event
FIGURE 5. Limacina robusta (Eames, 195); RGM 777423b, apertural view. Bar equals 100 μm.
FIGURE 2 in Pteropoda (Mollusca, Gastropoda, Thecosomata) from the Paleocene-Eocene Thermal Maximum (United States Atlantic Coastal Plain)
FIGURE 2. Specimen storage in the Naturalis (Leiden, NL) fossil holoplanktic mollusk collection.
Figure 1 from: Burridge AK, Janssen AW, Peijnenburg KTCA (2016) Revision of the genus Cuvierina Boas, 1886 based on integrative taxonomic data, including the description of a new species from the Pacific Ocean (Gastropoda, Thecosomata). ZooKeys 619: 1-12. https://doi.org/10.3897/zookeys.619.10043
Figure 1 - Holotype and paratypes of Cuvierina tsudai and holotype of Cuvierina pacifica. A Holotype (RMNH.5004167) and B–I paratypes (RMNH.5004168-72) of Cuvierina tsudai and J holotype of Cuvierina pacifica (RGM 458.690) photographed in a ventral view. Photographs of RMNH.5004169-72 from Burridge et al. (2015); RMNH.5004167-68 taken by R. van der Hulst and RGM 458.692 taken by E.F. de Vogel, this study. RMNH = Naturalis Biodiversity Center, mollusc collection and RGM = Naturalis Biodiversity Center, fossil planktonic mollusc collection, Leiden.

Figure 2 - Shape variation in Cuvierina tsudai and Cuvierina pacifica by means of Relative Warp (RW) data. Ordination of RW data of Cuvierina tsudai and Cuvierina pacifica for the first ventral and apertural RWs (N = 167 excluding 1 specimen with only one orientation). On the X-axis, RW1 depicts 78.26% of the total ventral shape variation. On the Y-axis, 69.43% of the apertural shape variation is explained by its RW1. Shape variations depicted by ventral and apertural RW1 (with subsequent RWs = 0) are shown.
