Data to Richter et al. 2020 Comparative analysis of worker head anatomy of Formica and Brachyponera (Hymenoptera: Formicidae) in Arthropod Systematics & Phylogeny

This dataset contains the ant head µCT-Sanning Datasets used for the article "Comparative analysis of worker head anatomy of Formica and Brachyponera (Hymenoptera: Formicidae)" by Richter et al. published in Arthropod Systematics & Phylogeny 2020. In addition, the image plates from that article (in highest resolution as TIF files) and a series of supplementary 3D-volume render video files are deposited. The datasets for CASENT0709409, CASENT0709411 and CASENT0790267 are deposited as they were used in this study (with transformation to adjust the orientation of the ant head to the global axes and cropped to reduce file size) while CASENT0709419 is deposited as the original scanning result as it was not modified for the work in this article. Scanning details can be found in the materials and methods section of the article. Scanning parameters were as follows: Power (W): 3W all specimens Voltage (kV): 40kV all specimens Voxel Size: CASENT0709409: 1,1557 µm3;  CASENT0709419: 1,2244 µm3;  CASENT0709411: 2,5527µm3 ; CASENT0790267: 2,8337 µm3  Exposure Time (s): CASENT0709409: 25 s;  CASENT0709419: 15 s;  CASENT0709411: 7 s ; CASENT0790267: 5 s Source Distance (mm): CASENT0709409: -9,5038 mm;  CASENT0709419: -9,5321 mm;  CASENT0709411: 10,038 mm ; CASENT0790267: 13,0037 mm Detector Distance (mm): CASENT0709409: 46 mm;  CASENT0709419: 43,0166 mm;  CASENT0709411: 16,5043 mm ; CASENT0790267: 18,0015 mm

Figure 1 in Contributions of Walter G. Ridewood to systematic comparative anatomy, especially of the osteology of ''lower'' vertebrates

Figure 1. Photograph to show how Ridewood disarticulated a fish skull in order to preserve the maximum amount of original articulation as well as to reveal the greater part of the internal skeleton. This is a skull of Scleropages leichardti (Günther 1864). Top: braincase and the right palate, hyomandibular, preopercle and lower jaw shown in medial view. Middle: left palate, hyomandibular and opercular bones in lateral view. Bottom: the ventral gill arches seen in dorsal view. This specimen (The Natural History Museum registration number BMNH 1905.3.20.6) was prepared and used by Ridewood (1905a) in his description of osteoglossid fishes.

FIGURE 4. 40 in New leontiniid Notoungulata (Mammalia) from Chile and Argentina: comparative anatomy, character analysis, and phylogenetic hypotheses

FIGURE 4. 40Ar/39Ar age spectra and inverse isochron plots for samples CH-31 (above) and CH-32 (opposite page). Age spectra illustrate apparent age versus cumulative fraction of 39Ar released. Shaded boxes indicate steps used to calculate weighted mean plateau ages. Plotting these steps suggests that most of them fall on simple isochrons with a 40Ar/36Ar ratio of the trapped component somewhat higher than atmospheric gas, giving a more reliable estimate of the ages at ~19.5 Ma, or ~19.8 Ma when corrected for a revised age of the Fish Canyon Tuff standard.
