Representatives of fossil mantis shrimps from the Jurassic (about 150 my old). Micro-fluorescence images. Specimens exposing areas of possible interest for comparison with our new data on Erugosquilla massavensis (Kossmann, 1880) (for taxonomic discussion on fossil species names, see[13]). A, C. ?Sculda pusilla, SMNS 67505. B, D. ?Sculda pennata/spinosa, SMNS 63293. A, B. Overview images; anterior body end to the right. C, D. Close-up of the dorsal areas of tagma III. C. Mandibles are well exposed in this specimen. The condensed area of the maxillipeds makes it difficult to detect if there are still tergites developed in this region (marked with question mark). D. Sclerotized valley folds are possibly developed in this specimen, but the interpretation is difficult. E. ?Sculda pennata/spinosa, MB.A.528. Early juvenile specimen, demonstrating the “normal” preservation, i.e., all details of the dorsal area of functional units II and III concealed by the shield. Abbreviations other than before: pl = pleomere; sh = shield; ts = trunk segment.
