Data to "Evidence for the evolution of eusociality in stem ants and a systematic revision of †Gerontoformica (Hymenoptera: Formicidae)" published in Zoological Journal of the Linnean Society

These are the µCT Datasets used in the study "Evidence for the evolution of eusociality in stem ants and a systematic revision of †Gerontoformica (Hymenoptera: Formicidae)" published in the Zoological Journal of the linnean society.
In the study, an amber piece containing 4 specimens of the stem ant genus †Gerontoformica was investigated, one of them being a pupa belonging to †G. gracilis (CASENT0741231), one adult belonging to †G. gracilis (CASENT0741232) and two adults of the newly described species †G. sternorhabda (CASENT0741233 and CASENT0741234). The adult specimen of †G. gracilis (CASENT0741232) had exception internal preservation, so higher magnification scans for anatomical details were performed. The dataset includes full body scans of all of these individuals, adjusted datasets in which the adult specimens were segmented out of the amber matrix (used for the volume renderings in the article) and the two head focused scans of †G. gracilis (CASENT0741232). The scanning parameters can be taken from the uploaded Scans Metadata Excel file, which is also part of the supplementary material of the related article. The two adult scans of †G. sternorhabda (CASENT0741233 and CASENT0741234) are in DICOM file format, all other data are in TIFF image format.
