Fig. 2. A. Remingtonocetus sp. (IITR-SB 2630) from Lutetian; Kachchh, India; right P4. B.?Remingtonocetidae indet. (USNM 449550) from Lutetian– Bartonian; Martin Marietta Quarry (formerly Superior Stone Quarry), near Castle Hayne, North Carolina, USA. Shown as if it were an upper premolar for comparison, but it may also represent a lower premolar as well. Note the extreme narrowness of the tooth. In lateral (A2, B2), medial (A1, B1), and occlusal (A3, B3) views.
Fig. 1 in The first possible remingtonocetid stem whale from North America
Fig. 1. PCA ordinations of differences in tooth morphology for sampled archaeocetes. This plot includes data from both adult and deciduous premolars. The numbers next to the axis labels indicate the percentage of explained variation in morphology for that axis. The tooth shapes around each point represent the outline generated using the harmonic coefficients produced by elliptic Fourier analysis to achieve 99.9% harmonic power. See SOM: table 1 for a list of included specimens.
ERA5-Land selected indicators daily aggregates for the Latin America region, 2023
<p>This deposit contains NetCDF files with daily aggregates from Copernicus Era5-Land eight selected indicators, covering the Latin America region, for 2023.</p> <p>Each file represents one indicator aggregation for one month of the year. Inside each NetCDF file, the layers contain the daily aggregates.</p> <p>For 2m dewpoint pressure, 10m u component of wind, 10m v component of wind, surface pressure, the mean function was used for aggregation. For total precipitation, the sum function was used for aggregation. For 2m temperature, the functions maximum, mean and minimum were used for aggregation.</p> <p>Those files were created using the <a href="https://github.com/ErikKusch/KrigR">KrigR</a> package.</p>

FIGURE 2 in Fossil snakes of the Penny Creek Local Fauna from Webster County, Nebraska, USA, and the first record of snakes from the Early Clarendonian (12.5-12 Ma) of North America
FIGURE 2. Composite time-stratigraphic chart of the Neogene of Nebraska correlated with the number of snake genera presently identified from the Central Great Plains for each North American Land Mammal Age (NALMA) substage. Abbreviations: He (Hemingfordian), Ba (Barstovian), Cl (Clarendonian), Hh (Hemphillian). Each point on the snake richness chart is summarized for each substage at that substage's midpoint, and is not necessarily correlated with a particular rock unit on the right.Species richness values include fossils from the entire Central Great Plains region, while localities from Nebraska specifically and discussed in this study are listed at each substage point and come from the rock units to the right. The star represents the data from this study, which updates the previous lack of data from Cl1 across North America (represented by the gray hashed line) with data from UNSM Wt-13B. NALMAs and substages are correlated with time based on data and figures from Tedford et al. (2004). Rock Units are adapted from Joeckel et al. (2017) and Tedford et al. (2004). Snake generic richness is modified and updated from Jacisin et al., 2015).

FIGURE 15 in Comparison of Miocene to early Pleistocene-aged Castor californicus (Rodentia: Castoridae) to extant beavers and implications for the evolution of Castor in North America
FIGURE 15. Comparison of the skull and dentary of extant Castor canadensis (MVZ 80744) and C. fiber (USNM 248154) to fossil C. californicus (USNM 26154). Note that the North American species C. canadensis and C. californicus share shorter nasals, wider occiput, and more posteriorly positioned orbits than Eurasian C. fiber; both also display more anterior placement of the anterior margin of the pterygoid insertion and greater spread of the posterior processes (coronoid, condylar, angular) than C. fiber.

FIGURE 14. Variation line graph calculated by coefficients of variation with sample size correction for Castor canadensis and C. californicus postcranial measurements. Note that C. fiber is excluded due to limited sampling. Castor canadensis and C. californicus both contains high levels of variation in postcranial elements. See Table 17 for descriptive statistics, coefficients of variation, and ANOVA results.
