Confocal and micro-CT data of Rhomeocalpsua torosa, holotype, NIGP180054

This dataset contains the raw confocal laser scanning microscopy (CLSM) slices and X-ray microtomography (micro-CT) slices for the holotype of <em>Rhomeocalpsua torosa</em> (NIGP180054) from mid-Cretaceous Burmese amber. This dataset is associated with the publication "<em>Rhomeocalpsua torosa</em> gen. et sp. nov., a unique lineage of Endomychidae from mid‑Cretaceous Burmese amber (Coleoptera: Coccinelloidea)" (DOI:10.11646/palaeoentomology.5.2.7). Confocal images were obtained with a Zeiss LSM710 confocal laser scanning microscope, using the 488 nm (Argon) or 566 nm (DPSS 561-10) laser excitation lines. The original CZI files are provided, which could be opened by the ZEISS ZEN software. Micro-CT data were obtained with a Zeiss Xradia 520 Versa 3D X-ray microscope. Scanning parameters were as follows: isotropic voxel size, 1.9324 μm; power, 4 W; acceleration voltage, 50 kV; exposure time, 1.5 s; projections, 3001. The TIFF stack is provided.
