This dataset contains the raw confocal laser scanning microscopy (CLSM) slices for the holotype of Coslonatus rasnitsyni (NIGP177330) from mid-Cretaceous Burmese amber. This dataset is associated with the publication "An aberrant colydiine-like tenebrionoid from mid-Cretaceous Burmese amber (Coleoptera: Tenebrionoidea: Zopheridae)" (DOI:10.11646/palaeoentomology.4.6.10). Confocal images were obtained with a Zeiss LSM710 confocal laser scanning microscope, using the 488 nm Argon laser excitation line. The original CZI files are provided, which could be opened by the ZEISS ZEN software.
